Products
（1）40kW~100kW prime genset, for continuous and stable power supply.
（2）45kW~110kW standby genset, for reliable and fast standby power supply.
Integrated water outlet manifold for cylinder head, reducing the sealing section and improving sealing reliability.
Advanced and mature BOSCH electronically-control common rail and high-efficient turbocharging technologies ensure accurate control of the fuel injection quantity and sufficient air intake, and thus sufficient combustion and low emission of the diesel engine under different loads.
Main structures such as the engine body, cylinder head, and crankshaft connecting rod are time-tested, ensuring high reliability. Good transient speed regulation and strong loading capacity, meeting the genset performance grade G3 requirements.
