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.
