It is shown that by means of recirculation there could be recieved the high coefficient of oxidizer (air) excess in engine cylinder when the coefficient of new oxidizer-consumption and fuel is rather low. It permits to reduce considerably the contents of the products of incomplete combustion. Moreover, during recirculation the temperature at the end of combustion reduces which influence the decrease of nitrogen oxide in exhaust gases.
