Cummins Westport Inc – the subsidiary of Cummins that produces natural gas engines for the commercial sector – are finishing field tests on its 8.9-litre “near-zero” NOx engine, with the company taking orders by the end of April.
The collaboration between the two companies brings in Cummins’ revolutionary engines with Westport’s natural gas innovations.
The company quotes that its engines meet or exceed the toughest emissions standards set by various agency’s including the U.S Environmental Protection Agency (EPA), The California Air Resources Board (CARB), and exceeds EURO emissions standard.
The ground-breaking power plant is said to reduce the emission of nitrogen oxide (NOx) – the gas which reacts with the ozone to produce smog.
The natural gas engine – labelled the ISL G NZ – is aimed at aiding trucking companies meet regulations set by the federal Environmental Protection Agency Clean-Air Standard that will be phased in from 2023 through to 2031 in the United States.
“These North America emission certifications result in a game-changing reduction in urban tailpipe and engine related emissions. This, combined with the reliability and operating improvements on the base ISL G engine, puts CWI natural gas engines at the forefront of cost-effective and dependable emission reduction strategies in transit, medium-duty truck and refuse applications,” said Rob Neitzke, President of Cummins Westport Inc
In practical understanding, if all 2200 transit busses in the city of Los Angeles converted to the Cummins Westport ISL G NZ (Near-Zero) engine, the total NOx output from the entire fleet would be equivalent to that of the emissions from just two buses in 1985 – a promising stride towards a greener future.
