WD615 truck special diesel engine has the following performance features:
■More fuel-efficient
WD615 truck diesel engine has a wide range of large torque and thus the better fuel efficiency under different conditions. With the optimization for the combustion and air intake systems, the engine performance has been significantly improved with the fuel consumption reduced by 10% or more.
■More powerful
176-280kW power covers broad range. The torque reserve up to 30% ensures that the vehicle is able to easily work in different conditions and deal with the complicated roads.
■More reliable
WD615 truck diesel engine has been through the several performance improvements and optimizations, with the unique frame type main bearing structure and robust body; the strict quality management system and the global sourcing of main components ensure the reliability of vehicle. The engine may work 10,000h without overhaul.
■More practical
One head for one cylinder facilitates the maintenance, and the components are versatile and most of them are interchangeable, reducing the costs; the dimensions of the whole series products keep consistent to facilitate the vehicle design and manufacturing.
■Greener
Through the optimization of combustion system, air intake system and fuel supply system, a full range of vehicle products of Weichai Power have the pollutant emissions lower than the limits of Euro II standard, with Euro III potential.
■More excellent
Good low-temperature start performance ensures that the engine is able to start normally at -15℃ without any auxiliary device; with the auxiliary device, it can start smoothly at -40℃; it can work normally at 5,000m plateau.
