Features
The original Cummins high power, high torque and turbo-charging 4-cylinder direct injection engine guarantees the high reliability and durability. The air-air inter cooler system over the compressed air can enhance the oxygen content upon combustion markedly. The center fuel injection under high injection pressure allows the uniform atomizing of fuel, guarantees the normal combustion and reduces the exhaust emission. And the engine conforming to Euro III A emission standard is optional.
