WAVE PISTON
The next evolution in piston design
Mack’s innovative wave piston design delivers 2% improvement in fuel economy and 90% reduction in soot. The waves in the piston bowl redirect flames in the combustion chamber to utilize all available oxygen for a cleaner and more complete burn than standard diesel pistons.

This direct injection system delivers ultra-precise control over fuel injection pressure, timing and volume. The result is more power and efficiency, with less engine noise. Save fuel, gain power and lower emissions.
CLEARTECH™ ONE
Do more with less
This next-generation single box exhaust aftertreatment system combines Selective Catalytic Reduction (SCR) technology and Diesel Particulate Filter (DPF) to deliver near-zero emissions and low maintenance in a lighter, more compact unit.
A turbo for all speeds
Variable Geomoetry Turbocharger
