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 road adaptability tests of approximately 3 million km (including high-temperature, alpine-cold, and plateau tests) and rigorous reliability bench tests of approximately 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

Supports high-efficiency turbocharger, fine calibration based on market segments and applications, improved 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 conditions

5. Safety and Comfort

Maximum speed control, limp-home mode, 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
