Brief Introduction to YC6M Series mono-fuel Engine

YC6M series mono-fuel engine is a compressed natural gas (CNG/LNG) mono-fuel engine specially co-developed by Yuchai and US E-controls Company for heavy-duty trucks. Its main components are interchangeable with those of YC6M diesel engine, and it has maintained all the advantages of YC6M diesel engine.

Application: Heavy-duty trucks

●Higher reliability

Electronic control system: gas feeding, ignition and engine management system;

platinum-plated electrode spark plug: High efficient combustion plus long service life;

 Air intake & exhaust and combustion system specially designed for gas engine;

Garrett GT37 water-cooled exhaust gas turbocharger: featured by higher efficiency and longer service life;

E-controlled air intake method: low density gas combustion, gentle combustion, high thermal efficiency, low exhaust temperature;

Oxygen sensor: a broad range of air-gas ratios accurately-controlled

Closed-loop control system for all working conditions plus self-learning and diagnosis.

●Lower noise

Gentle combustion, ultra-low noise, minor vibration, ease and comfort. Specifically, the average noise level < 93dB（A）

●Low emission

Oxidation catalyst converter, up to Euro III standard, further engines up to Euro Ⅳ available by upgrading, no visible carbon smoke and particle-free

●Easier maintenance

Human-oriented design, higher interchangeability and better approachability

 

●Higher performance & price ratio and better composite benefit
