YC6MK Inline 6 High-Speed Marine Diesel Engine | 350–450HP Lightweight & Fuel Efficient
Product Feature
1. Leading technology
YC6MK engine is a medium- and heavy-duty diesel engine with a displacement of 10L. It is designed and developed in strict accordance with FEV's mechanical development programs, with reference to the advanced diesel engine concepts of AVL, Ricardo and other international professional organizations.
2. Wide application
The 6MK engine platform has been applied to the development of vehicle engines, engines for engineering machinery, G-drive engines and marine engines. After years of test, development and application, the engine has had quite mature and perfect systems, and has subject to rigorous and extensive reliability tests and verifications.
3. Reliability and durability
High-strength water-cooled cylinder block, and integral four-valve cylinder head.
Reliability development in strict accordance with FEV's mechanical development programs; passed the road adaptability test of about 3 million km (including high-temperature test, alpine-cold test and plateau test) and the rigorous. reliability bench test of about 30,000 hours.
Use of BOCSH high pressure common rail system, Kamax bolts, Federal-Mogul cylinder gaskets, ZYNP cylinder liners, and parts of other professional suppliers

4. High efficiency and economy
Application of a four-valve structure and Yuchai's patented combustion technology, achieving a minimum fuel consumption of 190 g/kW·h
Supporting high-efficiency turbocharger, fine calibration based on market segment and applications, better economy and power performance
Use of an intelligent fuel-saving switch: The position switch is adjusted according to the real-time load, allowing the vehicle to operate in the economical range all the time, thus reducing the fuel consumption by at least 10%
Power coverage: 300 ps ~ 420 ps; torque coverage: 1,500 N·m ~ 2,000 N·m; high gradeability under heavy load condition
