The HiMSEN engine has just passed another milestone. The next generation CLEAN (Customer, Liability, Environment, Acceptable Technology, No Defect) HiMSEN engine has now completed type approval testing in the presence of eight major classification societies including ABS, DNV/GL, LR and KR.

The four-stroke CLEAN HiMSEN engine (Model H21C) improves power output by 20 percent and fuel efficiency up to 2 percent compared to the existing same class four-stroke engines, H21/32, while physical size and weight are 10 percent lower, thanks to the utilization of high pressure combustion technology.

The IMO Tier III-compliant engine emits 98 percent less NOx with the use of HHI’s proprietary Hyundai Selective Catalytic Reduction technology, NoNOx.

Mr. Youn Joong-geun, executive vice president of HHI’s Engine & Machinery Division said, “Our next-generation CLEAN HiMSEN engine is the culmination of our 40 years of technological know-hows and experiences.
