Cummins Announces Compatibility With Select Renewable Diesel Fuels

Whether you manage a public transit system or pupil transportation, there is always pressure to be sensitive to environmental concerns. To reduce the carbon footprint of transit and school buses, Cummins B6.7™ and L9™ engine platforms are now compatible with paraffinic renewable diesel fuels meeting the EN 15940 specification. This approval is for current model year engines and prior years as well. Paraffinic diesel fuels offer the potential to reduce greenhouse gas (GHG) emissions by 40 percent to 90 percent over the total life cycle of the vehicle compared with conventional fossil-based diesel fuel, and can be used as a 100 percent substitute for standard EN 590 or American Society for Testing and Materials (ASTM) D975 Ultra-Low Sulfur Diesel (ULSD).

ISL G NZ Now Shipping

Concerns about air quality in our major cities continues to be a driving force behind the spec’ing of natural gas engines in North American transit fleets. This is particularly true in urban districts that have been designated as non-attainment zones by the U.S. Environmental Protection Agency (EPA). The good news is that Cummins ISL G Near Zero natural gas engine is now shipping for installation in transit buses. The ISL G NZ achieves 90 percent lower NOx levels than the current EPA limit of 0.2 g/bhp-hr, and meets 2017 EPA greenhouse gas (GHG) emissions requirements, with a 9 percent GHG reduction from that of the current ISL G.
