Cummins upgrades engines lineup for North American truckers

ABR Staff Writer Published 23 March 2012

Cummins has carried out upgrade work across a full lineup of its diesel and natural gas commercial vehicle engines that the company says will deliver 2% fuel economy and better reliability.

The new enhance engine versions will be available to North American trucking customers in 2013, according to the company.

Cummins engines will use the same high-pressure common rail fuel systems, VGT Turbocharger and fully integrated electronics for combustion efficiency, performance and reliability.

The parasitic load on the engine through high-efficiency water, fuel and lube pump systems has been reduced with the new base engine improvements.

Cummins said that its engines will meet the 2014 fuel efficiency and greenhouse gas (GHG) standards beginning in January 2013.

All commercial vehicle diesel engines feature the Cummins emission solutions EcoFit ultra-low emissions exhaust aftertreatment system, integrating a diesel particulate filter (DPF) and selective catalytic reduction (SCR), while on-board diagnostics (OBD) will be extended across the entire lineup.

Cummins will also continue to offer the Westport ISL G, a natural gas engine, and will also introduce Westport ISX12 G which will go into full production in 2013.
