WD615
weichai

The Weichai WD615 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 9.726-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 WD615 engine series:
The Weichai WD615 engine is a versatile powerhouse, built to be the driving force behind a wide array of machinery :
Heavy-Duty Trucks & Buses: An ideal power source for heavy-duty transportation, providing reliable performance for long-haul and demanding routes .
Construction & Engineering Machinery: Extensively used in heavy equipment such as excavators, loaders, and cranes, where its durability is critical .
Marine Applications: Powers various vessels, including luxury yachts, inland waterway transport, and fishing boats, for both main propulsion and auxiliary power .
Power Generation: Serves as a reliable prime mover in diesel generator sets for prime, standby, and continuous power applications .
Agricultural Machinery: Provides dependable power for agricultural operations .
Robust Engine Design for Longevity: The engine incorporates a unique framed main bearing structure that creates a high-strength body, enhancing its ability to withstand high combustion pressures and ensuring a long service life . Key components are sourced through global procurement to guarantee reliability .
High Torque Reserve: With a torque reserve of up to 30%, the engine ensures strong acceleration and powerful performance under varying loads and complex road conditions, preventing stall and improving drivability .
Excellent Fuel Economy: Optimized combustion and advanced fuel system tuning result in very low fuel consumption across a wide power and speed range, leading to significant operational cost savings .
Outstanding Environmental Adaptability: The engine is designed for reliable operation in extreme conditions. It can start at temperatures as low as -15°C without assistance (and -40°C with aids) and perform efficiently at altitudes up to 5,000 meters .
Practical and Easy Maintenance: Featuring a "one-cylinder-one-head" design, maintenance and repairs are simplified, reducing downtime and service costs. Strong parts commonality across the series further streamlines inventory and upkeep .
Enhanced Safety with WEVB System: The optional WEVB (Exhaust Valve Brake) system acts as an engine brake, increasing the vehicle's total braking power by up to 55%, significantly improving safety on downhill slopes .
