This first 6UEC33LSH-C2 type main engine will be equipped on a coastal bulk carrier built by Yizheng Yangzi Shipbuilding Industry Co., Ltd.

The UEC33LSH-C2 engine was developed as a strategic core engine for UE licensing business to strengthen the lineup of the LSH series, which has received a number of orders, J-Eng said. The engine is characterized by a wide range of ratings – approximately 34% higher than the original rating – that covers a wide range from low to high engine speed so that it can be used on various types of vessels such as small bulk carriers, chemical tankers, cement carrier and LPG carriers.

The new engine also meets the demands for the energy saving and environment-friendliness required by tightened regulations, J-Eng said. It applies the structures and specifications of the latest technologies from the LSH series engine and incorporates new design concepts such as high-performance turbocharging and a low-pressure SCR system. Compared to the earlier UEC33LSII engine, a 4% reduction in fuel oil consumption is achieved, the company said.

This engine was developed and launched into the market in a very short period under the close cooperation between J-Eng and YDE in order to meet the growing demands for replacement of coastal vessels in China. YDE said it already has 10 sets of engine orders.
