1. Leading technology

The 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 testing, development, and application, the engine has mature and perfect systems and has undergone 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

Uses BOCSH high-pressure common rail system, Kamax bolts, Federal-Mogul cylinder gaskets, ZYNP cylinder liners, and parts from 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

5. Safety and comfort

Maximum speed control, limp home, torque output control, fault indicator lamps, low oil pressure protection, and thermal protection and control

Application of pilot injection control, intelligent idle speed control and other electronic control technologies, effectively reducing engine vibration and noise

Application of the special in-cylinder brake system with a low braking speed jointly developed by Yuchai and JACOBS, achieving higher braking efficiency than similar products
