For jobs that need a lighter weight and lower-cost engine, Mack has partnered with Cummins to offer the L9 engine with the best-in-class power-to-weight ratio.
The Single Module aftertreatment system combines selective catalytic reduction (SCR) and a diesel particulate filter (DPF) to reduce size and weight.
The L9 is fully compliant with On-Board Diagnostics requirements, and meets 2017 U.S. Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) greenhouse gas and fuel-economy regulations.
