Cummins Westport division debuts a Near Zero emissions version of their ISL G engine at this week’s 2017 NTEA Work Truck show. The engine received EPA and CARB certification of 0.02 g of NOx per horsepower per hour, which earns a designation of “near zero” emissions.
You may think of pickup truck and semi truck turbo-diesel engines, when you hear the Cummins name. The company is well known for powerful diesel engines across various classes of trucks. Cummins is an engine and powertrain specialist, but they offer a wide variety of power solutions and components: heavy equipment engines, marine engines, power generators, and much more. The Cummins Westport division is specializing in engines powered by natural gas.
Here are the specifications for the ISL G Near Zero engine. This 8.9L turbocharged inline-6 engine comes in five distinct power levels. This engine is meant for medium duty commercial applications, such as in school bus and waste management trucks. It’s no slouch, as the top power rating is 320 hp @ 2,000 rpm and 1,000 lb-ft of torque @ 1,300 rpm.
Here is a closer look at the Cummins turbo-diesel engine factory in Columbus, Indiana. One of the engines that is produced here is the 5.0L V8 turbo-diesel that is used in the Nissan Titan XD.
