Abstract

A method of diminishing the thermal effects of the exhaust gas recirculation in an internal combustion engine of a motor vehicle generally consisting of sensing the temperature of the gas at a selected point along the flow thereof, comparing the sensed temperature with a selected temperature and adjusting the supply of the gas responsive to a selected deviation of the sensed temperature from the selected temperature.
