B3.9

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

• Powerful Performance: 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: The reduced number of parts and lower failure rate significantly reduce overall engine repair costs, with repair time savings of 50% ; Cylinder bores utilize a platform grid honing design. The perfect geometry effectively prevents oil leakage. Advanced technologies such as new piston ring assemblies and sealed gasket roll-edge pressing are used to reduce oil consumption.
