WP10H Engine for Special-purpose Vehicle

Ultra-high reliability: The engine features high reinforcement and large design margins, with over 15,000 hours of accumulated bench testing and over 50 million kilometers of vehicle road testing; Service life exceeds 1.8 million kilometers/30,000 hours.

Modular design: Number of components reduced by over 30% compared to similar products—integrated fuel filter module with combined coarse and fine filtration; Engine oil filter module with integrated oil filtration, cooling, and water filtration; One-piece cylinder head with integrated intake manifold for a compact design.

Lightweight design: Total engine weight of only 815 kg—leveraging powerful CAE analysis capabilities to optimize design while ensuring strength and reliability; Extensive use of high-polymer materials or aluminum alloys for components such as the flywheel housing, water pump, oil pan, rocker cover, and intake manifold.

Intelligent control: Proprietary ECU, fully independently developed, providing rapid response and high-precision air control system; Full-operating-condition, multi-layered control strategies.

Excellent NVH performance: Noise at rated power point measured at one meter is below 96 dB(A), 2–3 dB(A) lower than competing products—engine block features a drum-shaped skirt design for high structural rigidity and low vibration, significantly reducing noise. Rear-mounted gear train uses high-precision gears and shear gears for stable operation and further reduction of mechanical noise; Multiple injection technology significantly reduces combustion noise.

Ultra-low fuel consumption: Minimum specific fuel consumption is 181 g/kW·h, with fuel consumption in common operating conditions 3%–5% lower than that of competing products; Low-speed fuel consumption zone covers the 1000–1400 rpm range typical for trucks, offering greater fuel efficiency.

High braking power: WCBS in-cylinder braking with a rated-speed braking power of 226 kW (23.8 kW/L); Compatible with a 630 L/min high-displacement air compressor to fully meet the air supply requirements of heavy-duty applications.

High adaptability: No power derating at altitudes of 2800 meters, and ultra-low power loss in common operating conditions at 4500 meters; Zero-failure start at -20℃ in low-temperature environments.
