Brief Introduction to YC6J Series mono-fuel Engine
YC6J series mono-fuel engine is a compressed natural gas (CNG/LNG) engine specially co-developed by Yuchai and US E-controls Company for medium-duty trucks. Its main components are interchangeable with those of YC6J diesel engine, and it has maintained all the advantages of YC6J diesel engine.
Application: Medium-duty trucks
Features
●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 TBP4 water-cooled exhaust gas turbocharger: featured by higher efficiency and longer service life;
E-controlled pressure regulating air intake method: low 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）
●Lower 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
