Cummins Inc has announced the readiness of its on-highway engine product line to meet the United States Environmental Protection Agency (EPA) and California Air Resources Board (CARB) emissions standards for 2007.

The firm’s engine line will be certified and compliant for 2007 with incremental improvements. Cummins will continue to use its cooled Exhaust Gas Recirculation (EGR) technology with the addition of exhaust aftertreatment provided by the integrated Cummins Particulate Filter and a crankcase ventilation system. This technology is consistent on all Cummins on-highway diesel engines for North America, including the Heavy-Duty ISX and ISM, as well as the MidRange ISL, ISC, and ISB engines.

The entire line has integrated electronic controls, with a single ECM (Electronic Control Module) that controls the engine and aftertreatment. All engines will use the patented sliding-nozzle Variable Geometry Turbocharger (VG Turbo), which offers an electric actuator for 2007 with improved response and precision in adjusting airflow to the engine.

Cummins’ Particulate Filter includes a diesel oxidation catalyst (DOC) and a diesel particulate filter to reduce particulate matter by 90%. The DOC optimizes the regeneration capability of the particulate filter. The crankcase ventilation system includes the Fleetguard Enviroguard coalescing filter, which captures and filters crankcase emissions and returns oil directly to the sump.
