Advanced design and high-quality manufacturing, adaptable to severe operating conditions, high strength, and reliable operation under heavy load.
The integration design of cylinder block and cylinder head prevents the engine from water and oil leakage. The parts are about 40% less than engines of the same type, and the failure rate is greatly reduced.
Forged steel camshaft and crankshaft, high-strength cylinder, multiple parts cast on the cylinder block, high rigidity, high pressure resistance, good reliability, and long service life.
Plateau honing cross hatch cylinder bore, perfect geometric structure that effectively prevents oil leakage, advanced technologies such as new piston ring assembly and gasket curling shield that reduce oil loss.
Holset supercharger with integral wastegate offers low-speed response and dynamic performance.
The three-stage filter ensures balanced particle dispersion, protects main components of the fuel system and maximizes engine life.
The electronic control system intelligently switches to operation modes according to the environment and operating conditions. It has self-diagnosis, alarm and remote monitoring functions.
The mature intelligent electronic control technology improves the overall performance of the engine. The engine specifications can be customized according to application requirements.
