Products
Power range：65kW~139.7kW
Applications：fishing boats, tourist ships of 10~20m, 55~75kW boat gensets, etc.
The water-cooled exhaust pipe + wet post-turbo pipe + efficient cooling heat exchanger and intercooler ensure good heat dissipation performance; the efficient combustion technology enables low fuel consumption and leading NVH performance in China.
Wide power range and high torque reserve.
Highly strengthened engine, with an overhaul period of over 10,000 hours.
Advanced high pressure common rail technology of Bosch enables accurate control and low fuel consumption.
