See the large picture

Relying on outstanding performance and quality advantages, WD615 specialized truck diesel engines have always kept superiority in medium and heavy-duty market and held constantly the first place in the market.

With the features of strong power, reliable performance and low noise, Weichai Power specialized Euro II truck diesel engines are ideal power for trucks.

Characteristic Performance of Specialized Truck Diesel Engine

  • More economical: WD615 diesel truck engine has a broad range of big torque, and its fuel economy is fine at all conditions. The performance has been improved obviously and the fuel consumption decreased by more than 10% after optimization for combustion
  • More powerful: Wide power range(196-323kW) and high torque backup (up to 30??) of the engine insure the vehicle working normally under all kinds of conditions.
  • More reliable: High rigidity of cylinder block with special framed main bearing structure, strict quality management system and global sourcing for major components insure the reliability of the complete engine. The target of durability reaches l0000h without major overhaul.
  • More practical: One cylinder one head is convenient in maintenance. Major parts of WD615 and WD618 engines are interchangeable thus lowers the running costs. Outline dimensions of the whole series are the same which can make design and manufacture easier.
  • Environmental protective: By optimizing of combustion, intake and fuel supply systems of the engine, emissions of exhaust pollutants from any Weichai Power product for vehicle are prior to the limit in Euro II regulation and has the potential to meet Euro III.
  • Good starting performance at low temperature: The engine can be started normally at -15?? without any auxiliary equipment,and it can be started smoothly at-40?? with auxiliary equipment.The engine can be operated normally at plateau with an elevation of 5000m.

Besides, the brake system of the vehicle can be controlled effectively by WEVB (Weichai Exhaust Valve Brake) system, and the brake rate has been increased by 55%, and thus the safty of both vehicle and passangers are increased.
