Important Information:

High Density of Power: Higher power output than competitive models at close displacement, the power of 3-cylinder can reach 4-cylinder level of competitors.
Low Fuel Consumption: Adopted European patent Quadram combustion chamber which can reduce fuel consumption, emission and noise, meanwhile raise engine power.
Good Appearance: Similar to original products of UK Perkins.
High Performance Cost Ratio: Having the similar performance of original products of UK Perkins, but the price is very competitive.
Good Cold Start Performance: Started normally at -10°C without pre-heater, starts smoothly at -25°C through flame preheating cold start device, meanwhile -40°C start solution is available.
Stability & Reliability: Stable and reliable engine performance, good market feedback.
