WP4.1N 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.

Major components such as the turbocharger, starter, and fuel system are sourced from world-class suppliers.

Subjected to the most rigorous bench, high-temperature, high-altitude, and high-humidity testing to ensure the reliability of key components, with an overhaul interval exceeding 12,000 hours.

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

Powerful Performance

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

Low-speed, high-torque design featuring high 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 and a wide economical operating range, with a minimum specific fuel consumption of 193 g/kW·h.

Comfortable and Environmentally Friendly

Rear-mounted gear train and enclosed flywheel housing effectively reduce noise, with standard-condition noise 4 dB(A) lower and unloaded noise 2.5–4 dB(A) lower than competing products.

Utilizes a secondary balancing mechanism and an offset piston pin design to deliver superior vibration characteristics compared to competing products.

Complies with IMO Tier II emission standards.

High Practicality

Optional configurations include dedicated LCD instruments, vibration-damping pads, and water-jacketed exhaust manifolds.

Over 95% of components are common with the N-series, facilitating ease of maintenance.

Control strategies can be adjusted according to different performance requirements.

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