MP®8HE
The MP®8HE combines the proven performance of our MP®8 engine with the high efficiency of Energy Recovery Technology to capture lost energy, convert it to torque and reduce fuel consumption.
Engineered for a new era of efficiency
With advances in design and engineering, the MP8HE engine earns up to 11 miles per gallon.
Improved Engineering
The improved wave piston design delivers a higher compression ratio inside a lighter, more efficient engine.
Advanced Efficiency
The updated turbo compound, auxiliary drive, gear ratio and EGR valve all work to deliver greater efficiency.
Training
The redesigned oil filtration system features two oil filters and uses a lesser viscosity oil for reduced consumption.
Evolved wave piston design
Mack’s innovative wave piston design redirects flames in the combustion chamber to utilize all available oxygen for a cleaner and more complete burn than standard diesel
pistons. The result delivers improved fuel economy and reduced emissions.
Next-Generation Energy Recovery Technology (ERT)
Capturing heat that would otherwise be lost, the MP8HE’s ERT feature converts exhaust emissions to mechanical energy and delivers it back to the crankshaft as torque. This
process enables the engine to operate at 1,000-1,100 RPM, saving fuel without sacrificing performance.
Power and performance
The MP8HE delivers consistent power and torque across a wide operating range that can be tuned to your needs for the right mix of power and high fuel efficiency.
Built to fuel efficiency
The direct injection common rail fuel system delivers ultra-precise control over fuel injection pressure, timing and volume. The result is more power and efficiency with less engine noise and lower emissions.
Cleaner emissions with ClearTech One
Mack’s improved exhaust aftertreatment system (EATS) is 17lbs lighter and takes up less space, which saves you fuel and money while improving flexibility.
