As a leading manufacturer of two-stroke diesel engine in the world, MITSUI E&S is proud of their abundant production record and experience.

Mitsui E&S Co., Ltd. has manufactured diesel engines in a single engine brand since it entered into the license agreement with MAN Energy Solutions SE (former Burmeister & Wain) in 1926. In June 2018, the accumulated production of MITSUI-MAN B&W diesel engines reached 100 million horsepower and exceeded 6,500 units As a leading manufacturer of two-stroke diesel engine in the world, we are proud of our abundant production record and experience. Today, LNG, ethane, methanol and LPG have been seen as alternative fuel selections for propulsion of ships, given its economic and environmental advantages. In accordance with the trend, demands for dual fuel diesel engines for marine use are increasing, called ME-GI/GIE/LGIM/LGIP which utilize them as fuel as well as heavy fuel oil and we proceed our production capacity and facility to provide various fuel engines. In addition, MITSUI E&S has been working for R&D with the Licensor to utilize ammonia and hydrogen as latest fuels for marine use. They are also taking positive steps to develop their own technologies and products for environmental and energy conservation. Turbo Hydraulic System type2 (THS2) is developed as a waste heat recovery system from turbochargers with hydraulic.
