Product Parameters

ADVANTAGES

Product Feature

1. Reliability

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 reliability bench test of about 30,000 hours

Use of a high-strength open cylinder block and an integral cylinder head, ensuring higher strength and stability

2. Strong power

Application of an advanced high pressure common rail (HPCR) fuel system and Yuchai's patented in-cylinder combustion technology, effectively improving the engine power and torque, and maximizing the load-carrying capacity of vehicles

3. Fuel economy

Application of Yuchai's patented open combustion chamber, unique in-cylinder combustion optimization technology and HPCR technology, effectively reducing fuel consumption

Road spectrum collection and fine calibration according to market segment and applications, ensuring fuel economy

4. Comfort

Reduction soft meshing starter, ensuring smooth start

Damping silicone oil damper

Application of pilot injection technology, reducing the noise by 2 dB
