Cummins QSB3.9 Diesel Engine

Product Advantages

• 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.
