Achieving optimum powertrain performance with proper service procedures
The Environmental Protection Agency (EPA) has established standards to reduce fuel consumption and greenhouse gas (GHG) emissions for the heavy duty trucking industry. These new standards have resulted in manufacturers developing every aspect of a truck’s powertrain to achieve optimum fuel efficiency. Part of this development includes calibrating engines to transmissions to maintain optimum powertrain
The perfect combination: The Zen of creating the optimum downsped engine/axle/drivetrain mix
Most truck engines, today, run at around 1,450 RPM at cruising speed to provide the 200 HP needed at the wheel-end. Engine downspeeding allows the truck to operate consistently in a more efficient range, generally between 1,100 to 1,200 RPM, while maintaining the same 200 HP at the wheel end. As a result, fuel efficiency
