Exhaust-fuel recirculation is a technique to control oxides of nitrogen, that are shaped by the chemical response of nitrogen and oxygen at high temperatures during combustion.

To realize this, exhaust gasoline is piped from the exhaust manifold to the intake manifold. This dilutes the incoming gas-air combination and successfully lowers combustion temperature. The quantity of recirculation is a operate of throttle place however averages about 2 %.
