The product pictured here is Quanchai 4JR3 harvester diesel engine, which offers many advantages, for example
1. Compact structure, reliable performance
This engine is jointly developed by Quanchai, Shangchai and Foton, which is designed using internationally advanced technology and software. The combustion system is subjected to hundreds of performance match tests so as to select the optimum fuel pump and nozzle.
2. Low vibration, low noise
Twin shaft balance design helps to eliminate the second order inertia force and thus reduces vibration, noise.
3. Good tightness, cooling effect
Designed with every possible leakage in mind, our diesel engine adopts built-in pipeline, thus effectively reducing the risk of leakage. The optimized cooling water jacket layout ensures maximum cooling area and accelerated cooling of cylinder.
4. Strong power, good economy
4JR3 diesel engine is powerful, fuel efficient, and so is used extensively in large and medium combine harvesters as well as tractors, engineering vehicles and light trucks.
