FOTON® Vehicle Engine

FOTON® vehicle diesel engine offers high reliability, as the key machine parts have undergone rapid fatigue tests, and finite element analysis is adopted to calculate the structural strength and vibration response of those parts.

The advanced combustion system, novel and efficient supercharger, as well as the P-style fuel injector largely improves the emission performance and reduces fuel consumption. The vehicle engine conforms to Euro II emission standard.

The mean effective pressure, horsepower per liter, and other key parameters reach national and international advanced level. Hence, the machine is ideal to supply power for light duty trucks, coaches, pickup trucks, SUVs, and MPVs.
