Products
（1）108kW~176kW prime genset, for continuous and stable power supply.
（2）120kW~190kW standby genset, for reliable and fast standby power supply.
The piston with the internal cooling oil passage technology effectively reduces the piston temperature and ensures a long service life.
High-strength alloy cast iron body, high-strength crankshaft, and cracking connecting rod are adopted, with high reliability which has been fully verified by experience. Meet the genset performance grade G3 requirements.
Advanced and mature BOSCH electronically-control common rail and high-efficient turbocharged & intercooled technologies ensure accurate control of the fuel injection quantity and sufficient air intake, and thus sufficient combustion, low fuel consumption, and low emission of the diesel engine under different loads.
