• Higher working efficiency: A longer stroke ensures more full combustion gas expansion, higher effective power output and lower fuel consumption under strong power; and the advanced 4-valve structure brings about higher horsepower, more thorough air combustion, and increased low-speed torque output, thereby improving the working efficiency.
• Leading manufacturing process: The forced-cooling articulated piston can withstand extremely high mechanical load and thermal load, and ensures a strength comparable to that of heavy-duty engines; the strengthened cylinder design greatly reduces the noise and vibration.
• Strong power: The air-to-air cooling and turbocharging technology ensures a better engine power performance.
• Lower emission: The center-arranged injector and symmetrical combustion chamber make the air-fuel mixture in the cylinder more uniform, the combustion fuller and the emission lower.
• Higher fuel economy: The fuel economy is higher, the service life is longer, and the durability and reliability are much higher than similar engines in China.
