Further orders for J-ENG’s new UEC42LSH

Japan Engine Corporation (J-ENG) has confirmed that it has received six follow-up orders for its new UEC42LSH engine. The first reference for the engine is a handysize bulk carrier under construction at a domestic Japanese shipyard, which is in the final stages of development. The vessel will be fitted with a UEC42LSH-Eco-D3 type engine.
The company told The Motorship it was targeting March 2021 for the first delivery of the UEC42LSH in 2019. As previously reported in The Motorship, in Tier 2 operation, the UEC42LSH is expected to achieve a fuel consumption rate of 164 g/kWh at maximum rating.
The company noted that the new engine had a smaller footprint than the preceding engine platform, while the engine’s fuel efficiency at slower operating speeds was highly competitive in its core small and medium-sized engine market segments.
The 42LSH-EGR type engine is equipped with the low-pressure exhaust gas recirculation (EGR) system. The EGR solution eliminates the need for the discharge of EGR bleed-off water. J-ENG notes that restrictions on such discharges are expected to be extended in some areas around North America and Europe in the future.
