The K12S 307-350kW Diesel Engine is designed and manufactured independently by Kangwo Power. Two fuel injection control systems are available for the series, which includes a common rail direct fuel injection and electronic unit pump system. Diesel engines in this series are highly reliable, high powered, and feature a stable operation with low noise levels.

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.

1. The 4-valve cylinder and camshaft designed piston engine top are designed to control the opening and closing of the valve.
2. Engines in this series are made of high strength materials.
3. Post-cast aluminum gear chamber: The gear chamber is manufactured using a lightweight and high-strength cast aluminum material. It has a light weight and low fuel consumption, with a maximum high burst pressure of 190bar.
4. The high-performance diesel engine has strict requirements in regards to the structure. Taking advantage of the combination of an overhead camshaft and roller rocker, the valve lash adjustment interval is doubled. A tight cylinder clearance design and multiple oil filters make maintenance of the machine easy.
5. The cold-start temperature is -15℃ without the use of any intake air heating devices during its assembling. The cold-start temperature is -30℃ with the use of an intake air heating device. It can be used in extremely cold areas, such as Russia.
