The Right Technology. EveryTM Time.

Cooled EGR is very effective at controlling Nitrogen Oxide (NOx). The EGR system takes a measured quantity of exhaust gas, passes it through a cooler before mixing it with the incoming air charge to the cylinder. The EGR system adds heat capacity and reduces oxygen concentration in the combustion chamber by diluting the incoming ambient air with cool exhaust gases.

During combustion, EGR has the effect of reducing flame temperatures which, in turn, reduces NOx production since NOx is proportional to flame temperature. This allows the engine to be tuned for the best fuel economy and performance at lower NOx levels.

Savings, Performance and Reliability.

Genuine Cummins EGR Coolers meet Cummins stringent specifications ensuring optimal performance for your ISX engine.
