What does Wei Chai engine P 10 mean?

P 10 refers to the engine model, specifically, the displacement, engine structure and horsepower are different from other engines. For example, the comparison between P 10 and P 12 engines shows that:

1. Different displacement, P 10 is 9.726L, and P 12 is11.596L. ..

2. The structure of P12 is complicated.

3. The horsepower of P10 is 240-375, and that of P 12 is 270-570. Wei Chai engine P 10 refers to Steyr WP 10 diesel engine in Wei Chai, and P 10 means the total displacement is 10L.

WP 10 series diesel engines are energy-saving and environment-friendly diesel engines jointly developed by Weichai Power and Austrian AVL Company, which meet Euro III emission regulations and have Euro IV potential. Its fuel consumption, emission, noise, reliability and other technical indicators have reached the advanced level in the world, and it is mainly used in heavy vehicles, buses and special vehicles. Variant products can be used in construction machinery, ships and power generation.

brief introduction

Technical characteristics of WP 10 series diesel engines;

(1) power and reliability technology: the length of the whole machine is shortened by 5%, while the impact load bearing capacity of the machine body is improved by more than 20%. The original casting and machining processes are used to ensure the manufacturing accuracy, and a reliability development method based on equal life design is established and applied.

(2) Safety technology: The engine exhaust valve braking device and the limping control method based on this device are developed, which effectively solve the vehicle safety problems caused by braking failure.

(3) Energy-saving technology: the dual-mode intake valve late closing and control mechanism was invented, and the dual-cycle heat exchanger and intelligent engine accessories were developed, which improved the combustion efficiency and total energy utilization rate of the engine.

(4) Environmental protection technology: metal honeycomb catalyst carrier, aftertreatment pipeline device, aftertreatment electronic controller and control strategy are developed, which improves the conversion efficiency and service life of engine aftertreatment system.
