Overhead camshaft

The camshaft design reduces the engine weight and improves rigidity through the one gap bridge valve.

Four valves per cylinder design

Two intake and two exhaust valves improve the intake and exhaust performance and efficiency. The maximum lift of the valve is reduced, improving the power performance of the valve system.

Charge air intercooling system

The diesel engine intake density is improved by adopting a charge air intercooler. Diesel engine output power and economy have been greatly improved without increasing heat load. NOx emissions are effectively reduced.

Integrated design of the exhaust manifold and heat exchanger

The integrated design of the exhaust manifold and heat exchanger places the exhaust manifold in a cavity surrounded by water. Outside circulating water lowers the exhaust gas temperature. The cooling effect is better and the noise is lower. The heat exchanger replaces a radiator tank and cooling fan to make the structure more compact.

OVERVIEW

Kipor uses an advanced emulation technology. Simulation analysis is conducted and an optimal design based on engine performance is established. Many systems such as intake, exhaust, and cooling make the performance and reliability excellent. The engine features four valves per cylinder, an overhead camshaft, turbocharging and inter-cooling. These make the engine stable in operation, lower in noise, higher in power and better in economy. The self-developed electronic speed regulator and common rail fuel system technology meet the Europe II Emission Standard, becoming a truly “Green Engine”. Power per liter and a specific weight and emission index are leading the field. They are the best choice of driving power for construction machinery, marine vessels and generators.
