43rd Engine Yearbook shows second wind for engines

08 July 2022

Samuel Clemens, better known under the pen name Mark Twain, once supposedly told a reporter that “the rumors of my demise are greatly exaggerated.”

Mr. Clemens, meet the combustion engine.

Because despite all of the negativity surrounding fossil fuels and the evolving promise of new technologies like electrification and hydrogen fuel cells, it appears that over the last 12 months, engines have started to get a bit of a second wind.

The most obvious indication of that can be seen on the chart below (NAFTA Engine Production - May 2022), provided by Power Systems Research ([email protected]), the global consultancy that tracks engines. Looking at production in the North American region, literally every power node in diesel, natural gas and gasoline engines saw improved sales over each of the last two years, some very improved. And that’s happened while coming off the COVID-19 pandemic and in the face of supply chain issues that just don’t seem to want to get any better.

Most engine manufacturers would be able to sell a lot more engines if they could either get components or, for those manufactured outside of the U.S., if they could just get engines.

Anecdotally, we’ve heard some suggest that they could see sales rise another 20% if they could just get products. There has also been talk of OEM customers being put on allocation, meaning that instead of X-number of engines, they’re only going to get Y, with Y being fewer. It’s got to be one of the most frustrating times in recent memory.

Compliance costs

At the same time, engines are still facing a lot of challenges. A case in point is the ever-increasing cost of compliance with upcoming engine emissions regulations. The Heavy-Duty Omnibus Regulations developed by the California Air Resources Board (CARB) set new standards, test procedures, warranty and reporting requirements for on-highway diesel engines used in trucks and buses. The new rules, which ratchet down NOx and greenhouse gas emissions significantly, go into effect in 2024.

There seems little question that engine manufacturers and their suppliers can once more step up their game and meet the new rules. But in this case, the age-old question “how much will that cost?” is the rub.

Estimates as to the compliance cost increase on 12 L and 13 L engines range from a low of just over $2000 per engine to a high of $80000, with the bulk of the guesstimates falling somewhere in between. For its part, CARB figures the additional per-vehicle price tag to be just under $8500.

Wherever the figure ends up, it’s going to be the latest in a long line of emissions-driven price increases that diesel engine and vehicle manufacturers – and ultimately vehicle operators – will have to find a way to again bear. And it won’t just be confined to California, since a lot of states tend to follow California’s lead on environmental issues, plus EPA is preparing its own regulations, which are not too dissimilar from CARB’s rules.

There are those who believe that part of the regulatory motivation is to make the cost of engines high enough that the financial difference between alternatives such as battery electrics and fuel cells won’t seem such a chasm. But that’s assuming a lot of things, particularly the existence of a widely available electric/hydrogen infrastructure, something that could cost trillions and take decades to create. In the meantime, there’s a lot of cargo to ship and other work to be done and engines will be around for a while to take care of that.

It should also be pointed out that the global engine manufacturing community isn’t exactly sitting around and waiting for something else to come along and take the business away. As shown in the following pages, engine manufacturers are doing what they ‘ve always done – working on products for today and innovating for tomorrow. As evidence of that, count how many times in the pages ahead you see the words “natural gas” and especially “hydrogen.”

It’s clear that we may be looking at something of a renaissance for engines in the next few years, with new technologies and new fuels bringing engines much nearer to the zero-emissions goal than seemed possible just a few years ago. A lot of that work is starting now, and you can read about a lot of it here. Enjoy!

For ease of installation, the IPUs are equipped with full aftertreatment mounting, an integrated cooling system, a full wiring harness and mounting for the ECM and fuel filter. This results in a plug-and-go design that Cat said saves the equipment manufacturers time through minimal engineering or design work, while still delivering the performance and efficiency customers expect from Caterpillar.

The engines are offered in ratings ranging to 74 hp for the C2.8 and to 134 hp for the C3.6. Full product support for the IPUs is provided by the global Cat dealer network.

Engine Technology

Caterpillar announced it is offering a whole-machine telematic solution that helps equipment manufacturers provide equipment owners and operators with the ability to view critical data output in real-time and better understand – and make use of – their machine’s operation. Leveraging the company’s years of experience with asset health monitoring, customers using this technology can locate, track and manage all of their connected assets independently.

Able to be integrated with existing telematics regardless of brand, the engine-ready solution can help provide a clear picture of a machine’s health by collecting all the machine data and displaying the results through an online dashboard. Users of the system can use it to monitor various functions, including machine location, uptime, fuel use, engine status and maintenance alerts. Data is customizable and reports can be scheduled and shared.

Equipped with remote services capabilities, the engine-integrated telematics solution can help minimize downtime via remote troubleshooting that can run diagnostic testing and pinpoint potential issues while the machine is in operation. If a repair is required, an OEM or dealer technician would be alerted and be able to complete the repair correctly in a single visit, Cat said.

Cummins announced what it called the industry’s first unified, fuel-agnostic engines. The new platforms, the first of which is expected to be launched in 2024, will be suitable for a wide range of on- and off-highway applications and will use engine blocks and core components that share common architectures, optimized for different low-carbon fuel types.

Derived from a common base engine, they will have a high degree of parts commonality. Below the head gasket, each engine will largely have similar components and above the head gasket will be different components for different fuel types. Each engine version will operate using a different single fuel.

This new design approach will be applied across the company’s B-, L- and X-Series engine portfolios, which will be available for clean diesel, natural gas and hydrogen. This technology approach will allow end users to select the right powertrain for their application and duty cycle with the lowest CO2 impact, Cummins said.

Common engine footprints will reduce vehicle and equipment manufacturer complexity and allow them to offer a range of fuel capabilities depending on customer needs, the company said. Parts commonality can provide similar troubleshooting and service intervals with minimal costs to train technicians and re-tool service locations.

Gas Engines

As part of the fuel-agnostic program, Cummins said it will bring to market a 15 L natural gas engine for heavy-duty trucks. The engine will offer ratings up to 500 hp and 1850 ft.-lb. of torque. Cummins said it is expected to weigh 500 lb. less than comparable current 15 L diesel engines while not requiring selective catalytic reduction (SCR) to meet 2024 California or Environmental Protection Agency emissions standards. When powered with renewable natural gas (RNG), the system can be credited with a neutral to negative carbon index, resulting in net greenhouse gas (GHG) emissions at or below zero, the company said.

Cummins said the universal 15 L platform for heavy-duty is also the basis for the hydrogen internal combustion engine currently part of the UK government supported Brunel project, which also includes the company’s medium-duty 6.7 L engine.

The development of the 6.7 L hydrogen engine will focus on medium-duty truck, bus and construction applications, such as excavators and wheel loaders. The 15 L platform offers the potential to bring hydrogen-fueled engine capability to heavy-duty long-haul trucks.

Cummins global technical centers will work together to achieve commercial viability for the H2-ICE project on a global basis. Part of the development work to be undertaken at Cummins’ Darlington, UK, facility will be supported by a funding award recently received from the UK government, provided through the Advanced Propulsion Centre.

Using proven and existing engine platforms for the H2-ICE program also means that Cummins will be able to use its existing engine production facilities and service support network, reducing costs and improving efficiency. In addition, the company can reduce vehicle and equipment re-development timelines, as many existing driveline components can be retained when paired with the hydrogen-fueled engines.

Corporate News
Cummins made a series of acquisitions earlier this year. In January, it acquired a 50% equity interest in Momentum Fuel Technologies from Rush Enterprises. The joint venture between Rush and Cummins will manufacture Cummins-branded natural gas fuel delivery systems for the commercial vehicle market in North America.

In February, Cummins and Meritor announced a definitive agreement through which Cummins will acquire Meritor, a global supplier of drivetrain, mobility, braking, aftermarket and electric powertrain solutions for commercial vehicle and industrial markets, for approximately $3.7 billion. The deal is expected to close by the end of the year.

Also in February, Cummins agreed to acquire Jacobs Vehicle Systems (JVS), a subsidiary of Altra Industrial Motion Corp., and a supplier of engine braking, cylinder deactivation, start and stop and thermal management technologies. The deal, worth $325 million, closed in April and is intended to provide growth opportunities for Cummins’ current and future advanced diesel engine platforms.

FPT Industrial has developed a new keel cooling system for its N40 250 E, N67 450 N and N67 570 Evo marine engines. The system is designed for vessels operating in brown and shallow waters looking to avoid the issues linked to seawater circuits.

Positioned along the keel or incorporated into the hull, the system is in constant contact with the water, enabling the efficient transfer of heat between the engine coolant and the water without circulation of salt water into the engine. This, FPT said, protects the engine from seawater corrosion and avoids continuous seawater filter obstruction and damage to the seawater impeller.

Diesel Hybrid

FPT Industrial has shown its vision of the powertrain of the future with the F28 Hybrid, a diesel engine paired with an e-flywheel that the company said results in an efficient, compact and sustainable solution for off-road applications.

The 2.8 L hybrid engine was developed to offer enhanced productivity and efficiency in compact equipment. With four inline cylinders, the engine delivers a maximum power of 74 hp, while the electric motor/generator adds 27 hp of continuous power and 40 hp of peak power. Light construction machines such as skid-steer loaders, drum rollers and backhoe-loaders can benefit from that peak power at certain times to complete their missions more efficiently, the company said.

In addition, the F28 Hybrid incorporates an optimized Start & Stop system for improved efficiency and a smoother engine start.

Emissions Technology
FPT said its newest patented HI-eSCR aftertreatment system is able to reduce the NOX levels more than 95% to meet EPA Tier 4 Final and EU Stage 4 emissions regulations. With no DPF, the system is maintenance-free and improves productivity by avoiding downtime during operation for filter cleaning or replacement, the company said.

For EU Stage 5 applications, FPT Industrial will integrate a maintenance-free filtering device on its SCR catalyst, thus enabling compliance with tightened limits on PM emissions within a compact package. This second-generation HI-eSCR 2 system, applicable for engines above 75 hp and below 750 hp, will maintain the same aftertreatment dimensions of the current Tier4 Final/Stage 4 applications while requiring no machine redesigns or layout changes for machine upgrades to the next emissions level.

Alternative Fuels
FPT Industrial supplied F28 natural gas engines for two New Holland TK Methane Power crawler vineyard tractors that are powered by biomethane and utilized at the Fontanafredda winery in the Piedmont region of Italy. The two tractors are part of a project with the wine producer to produce the first 100% sustainable wine.

The F28 four-cylinder engines are compact 2.8 L models rated 74 hp with 243 lb.-ft. of torque. The engines are designed without exhaust gas recirculation and utilize a three-way catalytic converter. The two biomethane tractor prototypes use biomethane produced locally from the anaerobic digestion of agricultural waste.

FPT Industrial is testing dimethyl ether (DME) in an 11 L heavy-duty diesel engine that is part of a project funded by the Swiss Federal Office for Energy (SFOE). Similar to LPG, the chemical properties of DME allow for very low NOx and particle emissions while maintaining high engine efficiency. Since DME combustion produces practically no particle emissions, a comparably simple SCR system without a particulate filter may be enough to comply with strict emissions standards, FPT said.

The first experimental data is showing promising results in terms of CO2 reduction, FPT said, along with very low NOx and particle emissions and similar engine efficiency to a diesel.

Gen-set Power

Available power when needed has become even more critical today with unpredictable hurricanes, tornadoes and storms. According to Isuzu, its open GenSet diesel power units can quickly put standby power solutions into customers’ hands for multiple generator applications.

The Tier 4-certified, 3.0 L, four-cylinder 4J Series rated 95 hp at 1800 rpm and the 5.2 L, four-cylinder 4H Series rated 171 hp at 1800 rpm are open power units engineered to provide pre-tested and over 90% validated ready power. Isuzu’s designs incorporate the SCR system in an over-the-flywheel mounting and the units are built with common components for multiple configuration options, including adjustable skid base crossmembers for bolt-on flexibility.

Isuzu said that its Tier 4 and Stage 5 engines and power units, branded under Isuzu REDTech in the USA, are designed to deliver quiet, low-maintenance, fuel-efficient power for existing and new applications. Flexible DOC (diesel oxidation catalyst) or DOC+SCR aftertreatment, with vertical or horizontal SCR configurations, are available and most of the Isuzu product lines are available with five-year/5000-hour warranties, the company said.

Alternative Fuels
Isuzu’s alternative fuel engines and power units use natural gas or propane and can be equipped with a dual fuel system designed to allow the fuel source to be quickly reconfigured, eliminating complexity and downtime. The dual fuel power units can change from one fuel to another while on location and without shutting down the entire job site for the change, Isuzu said.

This means that when natural gas service is interrupted, the dual fuel engines and power units can be switched off and restarted using a readily available propane tank, said the company, to keep projects or emergency power running with a clean available fuel source.

Over the last 15 years, JCB Power Systems said it has delivered significant improvements around air quality objectives related to its engines, with as much as a 98% reduction in NOx and particulate emissions from those manufactured in 2000. The company’s strategy to drive its products toward Net Zero includes multiple approaches including HVO and electric. However, JCB said the most important strand of its product strategy is hydrogen.

The company’s hydrogen internal combustion engine is based on the JCB Dieselmax 448 four-cylinder engine. To enable a largely drop-in solution, the bottom two-thirds of the engine are relatively unchanged, while on top is a new head and combustion system designed to support hydrogen as a fuel. The engine also incorporates additional venting for purging of any excess hydrogen fuel at shutdown.

JCB’s first hydrogen combustion engines were up and running by the end of December 2020, with numerous iterations developed since. Prototype machines have been running since 2021, and late last year, JCB announced a $138 million investment in hydrogen engine production, with the aim of providing the first H2 machines to customers by the end of the year.

Corporate News
Late last year, JCB reported that it had reached a production milestone of 750000 engines. The number covers engines built in the UK and India, which began assembling engines in 2011.

JCB Power Systems has appointed new dealers in several global regions. They include GHP Group covering Russia and Latvia; LMA Industrial responsible for Argentina; DERCOMAQ in Chile; ERCESA in the Czech Republic and Slovakia; Pitteri Violini Spa in Italy and San Marino; and Dutch distributor Brinkmann & Niemeijer, which is now also responsible for Germany and the Benelux region.

Engines for other applications enabling CO2-optimized and climate-neutral operation will follow by the end of 2023.

Rolls-Royce said it is further developing its mtu gas engine portfolio for power generation and cogeneration to run on hydrogen and thus enable a climate-neutral energy supply. Within this year, gen-sets powered by mtu Series 500 and Series 4000 gas engines can be operated with a hydrogen content of 25%. Rolls-Royce said it will continuously market new mtu gas engines for use with up to 100% hydrogen and, beginning in 2023, on a design-to order-basis, conversion kits will be available to allow already installed gas engines in the field to run on 100% hydrogen.

Corporate Developments
Rolls-Royce is making a $17.4 million investment at its mtu Aiken manufacturing facility in Graniteville, S.C., for the addition of a new Remanufacturing and Overhaul Regional Center. The 109000 sq.ft. expansion project will provide dedicated and streamlined remanufacturing and overhaul operations to support growth based on customer demand.

In October, Rolls-Royce marked the 25th anniversary of its mtu Series 2000 and Series 4000 engines. The engines have been used in mobile, stationary and marine applications and more than 100000 engines have been sold, amassing over 320 million operating hours.

Power Range
Diesel: 250 to 1800 hp (marine)
Gaseous Fuel: 252 to 2770 hp
Hydrogen: 338 to 1430 hp (H2 blends up to 50%)

New Engines
Siemens Energy Engines said it is developing a new EPA-certified gaseous fuel engine family for prime and standby power generation applications. The new engines will be available in a power range of 710 to 1540 hp and will be able to accept loads 10 seconds after startup.

The company said it is also completing its SM family of propane engines with a new 1430 hp model. The engine line, which begins at 368 hp, is optimized for power generation and CHP applications in 50 Hz and 60 Hz markets.

Engine Updates
Siemens Energy Engines said it has developed a new fast-start feature for its 1380 and 1460 hp SGE 56SL engines for 50 Hz applications. The T30 option allows the engine to ramp up to full load in less than 30 seconds when starting from zero. The operation includes startup and speed stabilization, grid synchronization, switch closure and load ramp to 100% operating in parallel to grid.

The company has also developed a high-power version of its SGE 56HM engine in 50 Hz applications for both parallel to grid and island mode operation. The engines deliver 1810 hp for paralleling and 1720 hp for island mode using natural gas, sewage and landfill gas.

Engine Technology
Siemens has developed an on-engine fuel blending system designed to allow dynamic blending of natural gas and biogas as a standard, factory-designed and supplied option for gas engines. Integrated into the engine controls, the system maintains a constant output from the engine, irrespective of variations in biogas availability, and ensures consistent energy supply even if biogas production falls to zero, the company said.

The system can seamlessly switch from 100% of one fuel to 100% of another or any combination in between, while maintaining 100% power output, Siemens said. The system was developed for SGE-SL (335 to 1430 hp) and SGE-HM (695 to 1810 hp) engines operating at 1200,1500 and 1800 rpm.

Siemens has also created a series of Modernization and Upgrade kits to update existing engine models in field. These can be used to increase the engine’s output, improve emissions and change the amount of heat available from the cooling circuits.

Siemens Energy Engines has a product line specifically designed to work with synthesis gases with a hydrogen gas content of up to 40%. The company’s extensive experience, with more than 20 years of working with synthesis gases, has allowed it to establish a clear line toward developing a new product exclusively designed and optimized for H2 fuel.

The current configuration of Siemens Energy natural gas engines enables mixtures with up to 15% hydrogen to be used while retaining engine performance, the company said. Additional changes will allow them to work with up to 50% hydrogen, with only slight changes in engine output compared to conventional natural gas engines.

Taking the configuration of the natural gas engine as the starting point, Siemens Energy Engines is working on improving the internal engine configuration, optimizing both the combustion chamber and the combustion cycle to obtain the best results with up to 20% hydrogen. For installed gas engines in the field that would like to operate with hydrogen fuel mixtures, Siemens Energy Engines said it is simultaneously working on the creation of the adaptation kits.

Gasoline: 200 to 430 hp (marine)

Industrial Engines
Volvo Penta offers a wide range of solutions for industrial off-road and power generation applications in North America, leveraging the close working relationship with the technology resources of the other companies in the Volvo Group.

Volvo Penta’s off-road Stage 5/Tier 4 Final D16 was named the Engine of the Year Above 175 hp at the Diesel Progress Summit. The judges stated that the decision was based on the dual-stage turbo system with a water-cooled charged-air system to ensure boost temperatures stay stable and low. They also acknowledged its extraordinary fuel efficiency and lower emissions using an SCR-based exhaust aftertreatment system with no diesel particulate filter, eliminating shutdowns for regeneration.

Volvo Penta said its new D8 Stage 2 and Stage 3/Tier 3 D8 gen-set engines have made inroads in the North American power generation market due to their power density and small size. They are proving to be very popular choices for OEMs, with their reliability, low cost of ownership, quick and compact installation, ease of maintenance and low-noise and vibration-free operation, the company said.

Commercial Marine Engines
In the North American commercial marine segment, Volvo Penta continues to carve out its position in niche markets such as pilot launches, including both Integrated Propulsion Systems (IPS) and shaft drives. The company recently was selected to supply its IPS for another Virginia Pilots boat, making a majority of its fleet powered by Volvo Penta.

Another strong emerging market for Volvo Penta is crew transfer vessels (CTVs) to service the new offshore wind turbines being deployed on the U.S. coastlines. The Volvo Penta IPS has been specified for a number of new CTVs, which will be required by federal law to be built in American shipyards.

Marine Technology
Volvo Penta’s EVC 2 (Electronic Vessel Control) system is now available across its full diesel engine range. The electronic network platform is designed to seamlessly connect and integrate all system components from helm to engine to prop. In the future, EVC 2 will act as the primary enabler for remote diagnostics and connectivity, Volvo Penta said. It will form the foundation for connecting all future features in a boat and allow new services to be uploaded anywhere in the world as automated connectivity and electric features become available.

Early this year, Volvo Penta announced its new Coastal Series corrosion protection package for V6 and V8 gasoline sterndrive and Forward Drive boats operating in salt and brackish water. It includes a seven-year coverage plan that is transferable with the boat if it is sold.
