B3.9

•   More Fuel Efficient: Originating from advanced design and superior manufacturing from Cummins, USA, resulting in lower fuel consumption compared to similar domestic products. 20%。

•   Powerful Engine: The design of the exhaust bypass valve leads to improved low-speed performance and better power.

•   Excellent Reliability: The integrated design of the cylinder block and cylinder head eliminates engine water and oil leaks; fewer parts than other similar engines 40% resulting in a significant reduction in failure rate.

•   Lower Maintenance and Repair Costs: Fewer parts and lower failure rates significantly reduce overall engine repair costs, with repair time saved by 50% ; Cylinder bores utilize a platform grid honing design. The perfect geometry effectively prevents oil leakage and employs advanced technologies such as new piston ring assemblies and sealed gasket roll pressing, reducing oil consumption.

•   Excellent Cold Starting Performance: Equipped with an intake air electric preheating device and 6.6kW a high-power starter, thoroughly improving engine cold starting performance, passing the extreme low-temperature verification test in China's Arctic Village, Mohe, -36 ° C extreme low temperature verification.
