5.9 L CUMMINS Engine
The Cummins 5.9L diesel engine has the advantages of small size, lightweight, and economy, as well as cleaner, quieter, and more fuel-efficient performance. Under strict adherence to maintenance regulations, the average time between failures reaches 1500 hours, and the average overhaul time reaches 6000 hours, or even longer. Even in extreme work cycle tests, this model still performs well, with low noise, lighter weight, and high power output per unit thanks to its world-class reliability.
5.9 L CUMMINS Engine
Cummins 5.9L engines include QSB59, 6BT5.9, and 6BTA5.9, all of which are inline six cylinder, four stroke water-cooled engines. The difference lies in the speed control and suction methods. QSB5.9 is an electronic speed control engine, with a turbocharged intercooling suction method. 6BT5.9 and 6BTA5.9 are mechanical speed control engines, with a turbocharged suction method.
QSB5.9
Power Range 103-209hp, emission level : China Stage-Ⅲ, The fuel mode is electronically controlled high-pressure common rail.
- Advanced design and sophisticated manufacturing, suitable for various harsh working conditions, with strong high-intensity and heavy load working ability.
- The cylinder block and cylinder head adopt integrated design, which eliminates the occurrence of engine water and oil leakage. The number of parts is about 40% less than other similar engines, and the failure rate is greatly reduced.
6BT5.9
Power range 125-132hp, emission level China Stage-I-Ⅲ, widely used in generator sets, excavators, ships and other equipment.
- Adopting forged steel camshaft and crankshaft, high-strength cylinder body design, multiple parts cast on the cylinder body, high stiffness, strong high-temperature resistance, good reliability, and longer service life.
- The cylinder hole adopts a platform mesh grinding design, with a perfect geometric structure that effectively prevents oil leakage, and adopts advanced processes such as new piston ring components and sealing gasket curling and molding.
6BTA5.9
Power range 152-180hp, emission level China Stage-Ⅲ, widely used in well-known brands of generator sets, rollers, excavators, loaders, and graders
- Adopting a Holset turbocharger with an integral waste bypass valve, it has strong low-speed response and power performance.
- The three-stage fuel filter ensures a balanced level of particle dispersion, protects the fuel system from major defects, and maximizes engine life.
