Cummins 07 Truck Engines Ready
Cummins Inc. said its on-highway engine product line is ready to meet the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emissions standards for 2007.
Cummins 2007 engine line will use cooled exhaust gas recirculation technology with the addition of exhaust aftertreatment provided by the integrated Cummins Particulate Filter and a crankcase ventilation system. This technology is consistent, Cummins said, on all its on-highway diesel engines for
The entire line also features fully integrated electronic controls, with a single electronic control module that controls the engine and aftertreatment. All engines will use the patented sliding-nozzle variable geometry turbocharger , which features an electric actuator for 2007 that Cummins says has faster response and improved precision in adjusting airflow to the engine.
The Cummins Particulate Filter includes a diesel oxidation catalyst (DOC) and a diesel particulate filter to reduce particulate matter by 90%. The DOC fully optimizes the regeneration capability of the particulate filter, a critical aspect for maintaining fuel economy comparable to today's engines, Cummins said. The crankcase ventilation system features the Fleetguard Enviroguard coalescing filter, which captures and filters crankcase emissions, and returns oil directly to the sump.
