Advanced design and sophisticated manufacturing, adapt to a variety of harsh working conditions, high strength, strong ability to work under heavy loads.
The cylinder block and cylinder head adopt an integrated design to prevent the occurrence of engine water and oil leakage. The parts are about 40% less than other similar engines, and the failure rate is greatly reduced.
Using forged steel camshaft and crankshaft, high-strength cylinder block design, multiple parts cast on the cylinder block, high rigidity, high pressure resistance, good reliability, and longer service life.
The cylinder bore adopts a platform mesh honing design, which is perfect The geometric structure effectively prevents oil leakage, and adopts advanced technologies such as new piston ring components and gasket crimping molding to reduce oil loss.
Adopt Holset supercharger with integral wastegate valve, low-speed response and strong power, three-stage fuel filter to ensure a balanced level of particulate dispersion, protect the main components of the fuel system, and maximize the life of the engine.
Electronic control system can intelligently switch the working mode according to the environment and operating conditions, and has the functions of self-diagnosis, alarm and remote monitoring.
