The deep rumble of the Cummins ISX engine pulls the big rig up steep hills, keeping pace with other heavily loaded trucks carrying goods to your local stores. The ISX engine is an option in nearly all manufacturers' heavy-duty trucks, reefers, and tankers. It is also an engine option in some motor coaches. It replaced the Cummins N14 in 2001 when new EPA regulations required that diesel engines meet the newest emissions requirements. The CM570, the original Cummins ISX engine, uses metering and timing valves to regulate the amount of fuel it supplies to the injectors. The following year, the CM870, or Cummins ISX EGR engine, incorporated an exhaust gas recirculation system to cool the exhaust fumes and recirculate them through the engine's intake to reduce nitric oxide and nitrogen dioxide emissions. More improvements on the ISX engines followed in 2008 and 2010, resulting in less particulate matter in the exhaust and continued improvement in emissions controls. When searching for Cummins ISX parts or accessories, the vast inventory on eBay provides a plethora of listings for the independent owner-operator, motor coach owner, or mechanic. Once the engine repairs are complete, the familiar Cummins diesel takes the truck back on the road, ready to deliver all necessities to your local retailers.Shop the extensive inventory of motors, parts, accessories, and Cummins commercial truck parts!
