The Los Angeles County Metropolitan Transportation Authority (Metro) completed an engine retrofit project to reduce emissions on a significant number of its fleet of more than 2,200 compressed natural gas (CNG) fueled buses.
Metro repowered 125 of its transit buses with new Cummins ISLG and L9N Near Zero Emission Natural Gas-Fueled Heavy Duty Engines, which will reduce emissions of nitrogen oxides (NOx) by 90% and greenhouse gases by 9%.
