Primary Applications & Equipment

The Weichai WP12.430E50 engine is built to be the powerhouse behind a range of heavy-duty equipment :

  • Heavy-Duty Trucks: It is a key power source for dump trucks and high-efficiency tractors, including models from manufacturers like PROJEN and JAC .

  • Construction Machinery: This engine is perfectly suited for excavators, cranes, and loaders, providing the necessary torque for demanding tasks .

  • Passenger Transport: Its reliable performance and low noise levels make it an excellent choice for 12-14 meter coaches and 14-18 meter buses .

  • Special Vehicles: Also applied in sanitation vehicles and other specialized commercial vehicles .

Core Technologies & Key Features

  • Advanced Common Rail & SCR System: The engine utilizes a high-pressure common rail fuel system combined with Selective Catalytic Reduction (SCR) technology . This ensures precise fuel injection and optimized combustion for superior fuel economy and lower emissions, complying with stringent Stage V standards .

  • Efficient Turbocharging and Intercooling: The turbocharged and intercooled (ATAAC) system forces more dense, cool air into the cylinders, significantly boosting power output and torque while optimizing combustion for improved fuel efficiency .

  • Robust Engine Design for Longevity: Built for maximum durability, the engine features a sturdy construction with a high-rigidity cylinder block and key components sourced through global procurement, contributing to a long service life and reliability in tough conditions .

  • High Torque at Low RPM: The engine delivers its massive 2060 N.m torque at a low RPM range (1000-1400 rpm), providing strong starting acceleration and superior pulling power, which is crucial for heavy-duty hauling and machinery operation .

  • Excellent Fuel Economy: Through optimized combustion, the engine offers fine fuel economy, with a minimum fuel consumption rate as low as 187 g/kW·h, helping to reduce operational costs .
