The World’s Cleanest Heavy-Duty Engine Runs on Natural Gas

The Cummins Westport ISX12N 11.9L 400 HP natural gas engine offers a 90% NOx reduction over the current NOx standard. Designed to be the lowest emission engine available today, this natural gas engine sets a new standard for performance and reliability while offering near-zero emissions. Not only does this engine dramatically exceed standards, it runs 90% cleaner than the cleanest running diesel engines. Continuous innovation in natural gas engine technology delivers immediate answers to our emission challenges and a fast track to running cleaner fleets today. The first step on the road to zero carbon starts with natural gas. Clean. Efficient. Innovative. Natural Gas is NOW. #CleanFleetMonth
