Construction Machinery Diesel Engine, 4GR3(Power From 46kw To 68kw)

This product page shows you Quanchai 4GR3 construction machinery diesel engine, which is one of our primary products. This diesel engine is jointly developed by Quanchai, Shangchai and Foton, which is the result of extensive experience, internationally advanced design technology and software. The combustion system is subjected to hundreds of performance match tests, which helps achieve optimal matching of combustion chamber, fuel pump and nozzle. In addition, the twin shaft balance design contributes to eliminating the second order inertia force, resulting in reduced vibration and noise. Moreover, built-in pipeline keeps possible leakage to a minimum, and optimized cooling water jacket layout ensures maximum cooling area and accelerated cooling of cylinder. These factors, coupled with high power, low fuel consumption and great reliability, have made our 4GR3 diesel engine increasingly used for construction machinery as well as tractors, harvesters, generators, etc.
