Abstract

PURPOSE:To minimize a discharge of HC and NOx in the exhaust, by controlling an EGR valve on a basis of the calculated value given in calculation of the amount of suction air per revolution in accordance with a set formula, upon detection of fuel consumption per one revolution. CONSTITUTION:In a Diesel engine 1 with a built-in supercharger for EGR, an EGR valve 12 is installed on a point midway to an EGR capillary tube 11 which short-circuits between the upstream side of a turbine part 9 of an exhaust tube 6 and the downstream side of a compressor part 10 of a suction tube 7, and the said EGR valve 12 is opened or closed by a diaphragm unit 15. In this case, an air flow sensor 20 is installed in a suction passage and at the same time an accelerator lever opening sensor 25 is as well installed by way of fuel consumption detecting. And, when fuel consumption per revolution is regarded as f and constant as d and B1, the amount of a suction air Ga per revolution is calculated from an equation of Ga=alphaf-beta1f<2> by a computer 50, a result from which a three-way solenoid valve 18 is governed, thereby controlling the opening of the EGR valve 12.
