Function and Application of WD615 Engine Assembly
The WD615 engine, manufactured byWeichai Power Co., Ltd., is a
classic heavy-duty diesel engine widely used in heavy trucks,
buses, construction machinery, and power generation equipment. Its
core functions and applications are as follows:
1. Power Output and Performance Features
• High Power and Torque Delivery:
• The WD615 engine features aninline six-cylinder, water-cooled,
four-strokedesign with a displacement range of9.726 liters to 15.3
liters. It delivers a maximum power output of343 kW to 353 kW
(460–480 hp)and a peak torque of2,100–2,300 N·m.
• This engine meets the power demands of16-ton to 40-ton heavy-duty
vehicles, making it suitable for long-haul transportation, heavy
cargo transport, and high-load operations.
• Multi-Variant Configurations:
• Available innaturally aspirated, turbocharged, and turbocharged
intercooledversions, allowing users to select the optimal power
configuration for specific applications.
2. Key Technical Advantages
• Robust Durability:
• Designed for heavy-duty use, the engine features reinforced
components (e.g., forged crankshaft, high-strength cylinder block)
to withstand extreme operating conditions.
• Fuel Efficiency:
• Incorporates advanced combustion technology and electronic
control systems to optimize fuel consumption while maintaining high
power output.
• Low Emissions:
• Complies withEuro II to Euro IVemission standards (depending on
variant) through exhaust gas recirculation (EGR) and selective
catalytic reduction (SCR) technologies.
3. Industrial Applications
• Heavy-Duty Trucks and Buses:
• Powers long-haul freight trucks, dump trucks, and city buses,
ensuring reliable performance in diverse road and load conditions.
• Construction and Mining Machinery:
• Used in excavators, loaders, and cranes, where high torque and
durability are critical for demanding tasks.
• Power Generation:
• Serves as a prime mover in diesel generator sets, providing
stable electricity supply for industrial, commercial, and emergency
applications.
