Mitsubishi Heavy Industries, Ltd. (MHI) has started development of a new UEC45LSE
ships engine with a cylinder bore of 45cm as the latest LSE series of the UE diesel engine family. LSE engine series are now developed with the concept of Four “E”s: Excellent reliability & Economy, Environment friendly, Easy maintenance. MHI will pursue engine reliability based on the abundant experience accumulated through UEC68LSE, 60LSE, 52LSE, and 50LSE engines. The
cargo ships with new engine is targeted to be applied to 30,000 to 40,000DWT class bulk and product carriers. The new design concept also allows equipping the SIP lubricating system for cylinder liners which has a good reputation in the market. Moreover, the new engine follows the UE engine feature of high economy represented by low fuel oil consumption and low lube oil consumption. MHI own-developed high-precision analysis tools for in-cylinder combustion simulation, elasto-hydro dynamic (EHD) analysis for main bearings, etc., as well as the 3D-CAD system will be used to raise reliability, and simultaneously to shorten the time required for the development to achieve earliest marketing. For this class of engine, 250 units of UEC52LA diesel engines have been built and delivered mainly for 30,000DWT class bulk carriers since 1985 when the model was marketed. The UEC52LA is designed specially for cargo and
cruise ships built by licensees i n c l u d i n g Akasaka Diesels Limited and Kobe Diesel Co., Ltd. has been highly appreciappreciated in the market, for the high operational reliability of the engines, and at present, many engines are still listed in the backlog order book. However, the 20 years since the debut has led the company to develop a new engine satisfying today’s requirements for lighter, more compact, and higher performance. The UEC45LSE will thus be developed based on both new technologies of the LSE engines and reliability of the UEC52LA engines. The new UEC45LSE diesel engine is expected by the customers as a successor to the best seller UEC52LA diesel engine. Thus, MHI will continue to exert utmost effort with licensees to market the latest UEC-LSE series featuring high performance together with the other existing series including the UEC-LSII/LSE models. The engine is great for cruise ships, cargo ships and designed according to some innovations made to newest
yachts of the world.
