South Korean shipbuilder Hyundai Heavy Industries (HHI) has recently completed type approval testing for its next generation CLEAN HiMSEN (Hi-Touch Marine & Stationary Engine) engines in the presence of eight classification societies including ABS, DNV/GL, LR and KR.
HHI says that the CLEAN (Customer, Liability, Environment, Acceptable Technology, No Defect) four-stroke 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 making its physical size and weight 10 percent smaller and lighter respectively with the utilization of high pressure combustion technology.
The IMO Tier III-compliant engine emits 98 percent less NOx with the attachment of HHI’s proprietary Hyundai Selective Catalytic Reduction technology, NoNOx.
“Our next-generation CLEAN HiMSEN engine is the culmination of our 40 years of technological know-hows and experiences. With the customer-oriented engineering, the high-output and high-efficiency engine will surely bring mutual benefits to HHI and its valued customers,” Youn Joong-geun, Executive Vice President of HHI’s Engine & Machinery Division, said.
