WP12 Series

Safe and Reliable

High-strength design of structural components including the engine block, pistons, and bearings ensures diesel engine reliability under high peak firing pressures.

Leverages the Weichai global supplier system to ensure reliable component quality.

Undergoes the most rigorous endurance testing to ensure the reliability of critical components.

Advanced self-diagnosis system, comprehensive fail-safe modes, and secure control strategies.

Powerful Performance

Precision electronic control for electronically governed models provides high injection pressure, minimal speed fluctuation, and robust power output.

Low-speed, high-torque design featuring a 25%-35% torque reserve, rapid response, and quick acceleration.

Economical and Fuel-Efficient

Optimized injection strategies precisely control injection pressure, quantity, and timing, ensuring thorough fuel atomization with a minimum specific fuel consumption of 192 g/kW·h.

Comfortable and Environmentally Friendly

Electronic control models support multiple injection strategies, including pre-injection and post-injection, reducing noise and vibration by 20% compared to mechanical pump systems.

Water-jacketed exhaust manifold and tailpipe are designed to lower engine room temperatures.

Complies with IMO Tier II emission standards.

High Practicality

Horizontal air filter and rear-mounted turbocharger reduce the overall height, facilitating engine room installation.

Control strategies are adjustable to meet diverse performance requirements.

Supports multiple control signal inputs/outputs to meet automated control requirements.
