Cummins' ISL G natural gas engine for truck and bus.
Cummins unveiled the complete product portfolio for the transit bus market showcasing, diesel, diesel-electric hybrid and natural gas engines designed to meet the 2013 U.S. EPA emissions regulations and new greenhouse gas (GHG) and fuel-efficiency standards.
The EPA 2013 emissions regulations call for all on-highway engines to be equipped with On-Board Diagnostics (OBD). OBD monitors emissions-related engine systems and components and alerts the operator of any malfunctions. OBD is designed to further enhance the engine and operating system by providing early detection of emissions-related faults.
In addition, new regulations for 2014 have recently been finalized by the EPA and the U.S. Department of Transportation (DOT), instituting equivalent carbon dioxide and fuel-efficiency standards. By burning less fuel in the engine, Carbon Dioxide, which is the main GHG controlled under this regulation, is simultaneously reduced. Nitrous oxide and methane are the other regulated GHGs.
Cummins has announced that it will meet the OBD as well as the GHG and fuel-efficiency requirements by Jan. 1, 2013. "The ability to meet the GHG reduction standards ahead of time alongside the OBD requirements for 2013 allows us to assure customers that we are committed to bring clean products to market even sooner," stated Tom Hodek, general manager - North America Bus Business. "This approach provides customers with a single product launch so transit bus properties will not be faced with further product changes for 2014."
