Diesel engine WP9H series

6-cylinderturbo-intercoolercommon rail

Compact structure, high reliability, high power performance and excellent economy. The new generation of Weichai engine products, which combine the achievements of new technology to meet Euro V/VI emissions, are more powerful, economical, and reliable than competing products, applied in port tractor. Extreme reliability •The engine has a high degree of reinforcement and a large design surplus, and the total length of the bench test has exceeded 15,000 hours, while the total length of the road test has exceeded 50 million kilometers •Life exceeds 1.8 million km/30000 hours Modular design •Parts are more than 30% less than similar products - integrated fuel filter module, primary filter and fine filter integrated design •Filter module, oil filter, cooling, rotor filter, water filter integrated design •Integral cylinder head with integrated air intake pipe for compact design Lightweight design •The total machine weighs only 805kg - powerful CAE analysis capability, optimized design while maintaining strength and reliability Intelligent control •Self-contained ECU, fully self-developed, responsive, high-precision air control system •Total performance, multi-level control strategy Excellent NVH performance •Less than 96dB(A) per meter of rated power point - the body is drum-shaped skirt design, with high body strength and low vibration, which greatly reduces noise •Rear gear chamber, high precision gear is used to shear gear, which provides stable operation and further reduces mechanical noise •Multiple injection technology to reduce combustion noise significantly
