Mack LR and TerraPro models are now available with the Cummins Westport L9N natural gas engine, enabling customers to meet near zero NOx emissions levels while providing excellent performance and efficiency.
The spark-ignited L9N is capable of running on compressed natural gas (CNG), liquefied natural gas (LNG) or renewable natural gas (RNG). It produces 320 hp and 1,000 lb.-ft. of torque.
According to Cummins Westport, the L9N is among the lowest certified NOx emission engines available in North America, producing NOx exhaust emissions that are 90 percent lower than the current EPA limit of 0.2 g/bhp-hr. The L9N is also certified to the EPA’s GHG2017 emission requirements.
