Features
The use of four valves per cylinder, an electronic governor and P11 high pressure oil pump can effectively improve combustion and emission to deliver smooth operation and efficiency. With a gantry cylinder block, rear gear chamber and reasonably distributed strengthening rib, the engine features good rigidity, compact structure, and minimal vibration and noise. The split camshaft design ensures accurate control of valve and injection timing. The optimized cam profile can reduce impact force and improve the reliability and durability. Equipped with an electronically controlled priming oil pump, the automatic oil pre-supply is achieved when starting up. This engine satisfies Off-Road China II emission standards.
