MITSUI-Everllence B&W Engine
MITSUI E&S's Marine Engines Leading the World in Next-Generation Fuel Compatibility
MITSUI E&S boasts the top share in Japan for large low-speed two-stroke marine engines.Since entering into a technical partnership with Everllence (formerly Burmeister & Wain) in 1926, we have been manufacturing engines under the single brand "MITSUI-Everllence B&W" and in November 2024, we achieved a cumulative production of 120 million horsepower. Looking ahead, we have shifted the focus of our main products from heavy oil engines to dual fuel engines (DF) that can burn methanol and LNG in order to achieve zero net GHG emissions. While expanding our manufacturing capabilities for various DF engines, we are currently developping ammonia dual fuel and hydrogen dual fuel engines, which are the ultimate zero-emission fuels.

NOx Tier III Technologies
We provide technologies that comply with nitrogen oxide (NOx) regulations. EGR reduces NOx generation by cooling and cleaning a portion of the exhaust gas, then recirculating it to the exhaust receiver. SCR is a technology that reduces NOx contained in exhaust gas to nitrogen and water, rendering it harmless.
