Cummins engine line will be certified and compliant for 2007 with only incremental improvements. Cummins will use its proven 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.
