Description
Kangwo collaborates with numerous power plants for consultation, manufacturing, debugging and maintenance of the diesel engines. We provide customized diesel engines according to client's technical requirements and offer feasible solutions. By working with an internationally known internal combustion engine manufacturer, we are able to design and produce the 64kW-171kW diesel engine.

Our diesel engines have reached the European IV emission standard and European V emission standard. And passed CE certification of EU, ISO9001 international quality authentication, GB/T28001-2011, OHSAS18001:2007 and other certifications.

Features
1. Four Valves
A four-valve structure ensures efficient space usage, which allows for a larger air flow opening during each valve's respective stroke.

Getting adequate air helps to improve the diesel engine's power per liter and torque per liter, which are the two standards by which the engine performance is measured. Therefore, a four-valve structure guarantees a high performance in the diesel engine.

2. Electronic Governor
The electronic governor allows for a high regulation precision, and meets the requirements for a high speed droop from the plant station.

3. Low Fuel Consumption
A P-type diesel fuel injector design is a new invention in the field. The design places the oil atomizer in the middle, allowing full fuel atomization and low fuel consumption.

4. Low Swirl Intensity and Mass Flow
The cylinder head is made of an alloy cast iron, which guarantees its stiffness and strength. The optimized design of the air passage meets customer requirements for a high power, low fuel consumption, and low emission.
