Abstract
The temperature and air-fuel ratio of the exhaust gases of an internal combustion engine are sensed to generate signals indicative thereof and the amount of fuel to be injected into the engine is determined in accordance with the signals, thus controlling the air-fuel ratio at a predetermined value and thereby decreasing the abnormal temperature rise in the exhaust system.
