Cummins DCEC QSB5.9 engine advantages
• Advanced design and sophisticated manufacturing, adapt to a variety of harsh working conditions, high-strength, heavy-duty work ability
• The integrated design of the cylinder block and cylinder head prevents the occurrence of water leakage and oil leakage of the engine. The number of parts is about 40% less than that of other similar engines, and the failure rate is greatly reduced
• Adopt forged steel camshaft and crankshaft, high-strength cylinder block design, many parts are cast on the cylinder block, high rigidity, strong high pressure resistance, good reliability and longer service life
• Cylinder bore adopts platform mesh honing design, perfect geometric structure effectively prevents oil leakage, and adopts advanced technology such as new piston ring assembly and sealing gasket crimping molding to reduce oil consumption
• Adopt Holset supercharger with integral wastegate, low-speed response and dynamic performance
• Three-stage fuel filtration ensures balanced particle dispersion levels, protecting major fuel system components and maximizing engine life
• The 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
• Mature intelligent electronic control technology improves the overall performance of the engine, and the engine specifications can be customized according to application requirements
