weichai

The Weichai WP12.375E50 is a robust and efficient 6-cylinder, in-line, 4-stroke diesel engine renowned for its exceptional durability, reliable power, and superior fuel economy . With a substantial 11.596-liter displacement and featuring turbocharged and intercooled aspiration, this water-cooled engine is engineered to deliver consistent performance in the most demanding transportation, construction, and industrial environments . Its proven technology and robust construction make it a trusted power source for a wide range of heavy-duty equipment .
For a quick overview, here are the core specifications of the WP12.375E50 engine:
The Weichai WP12.375E50 engine is built to be the powerhouse behind a range of heavy-duty equipment :
Construction Machinery: It is a key power source for 100-ton mobile cranes, such as the ZTC1000V653 model from Zoomlion .
Heavy-Duty Trucks: This engine powers short-range lightweight tractors like the XCMG G5 series, and is also found in 8x4 dump trucks .
Commercial Vehicles: Its reliable performance makes it suitable for sanitation vehicles, postal trucks, and construction dump trucks .
Passenger Transport: The engine is also applied in 12-14 meter coaches and 14-18 meter buses .
Advanced Common Rail Fuel System: The engine utilizes a high-pressure common rail fuel system, which ensures precise fuel injection . This technology leads to optimized combustion, reduced fuel consumption, and lower emissions .
Efficient Turbocharging and Intercooling: The turbocharged and intercooled system forces more dense, cool air into the cylinders, significantly boosting power output and torque while optimizing combustion for improved fuel efficiency .
Low Speed & High Torque: The engine delivers a massive 1800 N.m of torque at a low RPM range (1000-1400 rpm) . This provides 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 .
SCR Emission Control System: To meet stringent emission standards like China National Stage V, the engine employs SCR (Selective Catalytic Reduction) technology, effectively reducing NOx emissions .
