Hyundai Heavy Industries (HHI), the world’s largest shipbuilder and marine engine maker, has recently completed type approval testing for its next generation CLEAN (Customer, Liability, Environment, Acceptable Technology, No Defect) HiMSEN engines with eight major classification societies present, including ABS, DNV/GL, LR and KR.
The CLEAN four-stroke HiMSEN (Hi-Touch Marine & Stationary Engine) engine (Model H21C) improves power output by 20% and fuel efficiency up to 2% compared to the existing same class four-stroke engines, H21/32. By utilising high pressure combustion technology, the engine’s size and weight are reduced by 10%.
The IMO Tier III-compliant engine emits 98% less nitrogen oxide (NOx) emissions with the attachment of HHI’s proprietary Hyundai Selective Catalytic Reduction (SCR) technology, NoNOx.
HiMSEN is the world’s most selling medium-speed marine engine and was developed by HHI in 2001.
Since then, HHI has exported about 10,000 HiMSEN engines, accounting for 21% global market share.
