Operation

Specific to:

Honda CR-V 2007-2008

The Exhaust Gas Recirculation (EGR) system is used to reduce nitrogen oxide emissions. EGR works by recirculating a portion of the engine's exhaust gas back to the engine cylinders. The exhaust gas increases the specific heat capacity of the mix lowering the peak combustion temperature. The EGR is controlled by the PCM for maximum efficiency.
