Product advantages
• Advanced design and sophisticated manufacturing, adapt to various severe working conditions, high-strength, heavy-duty operation ability

• The cylinder block and cylinder head adopt integrated design to prevent the occurrence of water leakage and oil leakage of the engine. The parts are about 40% less than other similar engines, and the failure rate is greatly reduced

• Adopt forged steel camshaft and crankshaft, high-strength cylinder design, multiple parts are cast on the cylinder body, high rigidity, high pressure resistance, good reliability and longer service life

• Cylinder bore adopts platform net honing design, perfect geometric structure effectively prevents oil leakage, and adopts advanced technical processes such as new piston ring assembly and gasket crimping molding to reduce oil loss

• Use Hlset supercharger with integral wastegate valve, low speed response and strong power

• The three-stage fuel filter ensures a balanced level of particulate dispersion, protects the main components of the fuel system, and maximizes the life of the engine

• Electronic control system can intelligently switch working modes according to the environment and operating conditions, and has self-diagnosis, alarm and remote monitoring functions

• Mature intelligent electronic control technology improves the overall performance of the engine, and the engine specifications can be tailored according to application needs
