622 Series Engine
622 series diesel engines are China’s largest high-speed and high-power diesel engines independently developed by Henan Diesel Engine Industry Co., Ltd (HND) through technological innovation. HND adopts mature high-pressure common rail and intelligent control technologies from both domestic and international sources. 622 series diesel engine bore/stroke: 170/215mm, power coverage: 2080-4000kW, speed range: 1500-1800rpm. Mechanical pump diesel engines meet Tier II and Tier III emission standards.
622 series diesel engines have the characteristics of compact structure, high reliability, small size, light weight, convenient operation and maintenance, and reasonable appearance layout. They are now widely used in ships, power stations, locomotives, engineering machinery and other fields.
