Powerful: Optimized turbocharger, high-pressure fuel pump and fuel injector, with wide power coverage, larger torque reserve and high torque at low speed better for various working conditions.
Low fuel consumption: pulse conversion turbocharger makes combustion more adequate and fuel consumption lower, with wider low fuel consumption work area. Through the optimization of the oil seals, the oil consumption is reduced by 45%.
Fast start: The compression ratio is accurately calculated, and the high-power starter allows the engine to have stable idle speed and excellent low-temperature starting and acceleration performance.
High reliability: high-strength QT800 integral crankshaft, large-flow oil pump, oil is filtered first and then cooled to ensure reliable performance of diesel engine, less tube and split head design ensure the reliability and maintenance of the engine.
