Abstract

PURPOSE: To provide an exhaust turbo-supercharged engine, in which arrangement is such that a portion of supercharging air supplied from blower compressor to engine is blown to the exhaust system at the time of accelerating and decelerating engine, so as to enrich the mixture ratio of mixture supplied to the engine, whereby it is enabled to simplify the structure of mixture-ratio controlling system.
CONSTITUTION: In order to control air-fuel ratio of mixture supplied to engine 1, which is of a fuel injection type and is equipped with an exhaust turbo-supercharger 4, to keep it substantially constant, supercharging passage 9 extended from blower compressor 6 to engine 1 is connected to the exhaust system via blow passage 16. Control valve 17 disposed in the blow passage 16 is so arranged that it is opened when the load of engine 1 is low and closed with delay of a proper time period when the engine load is increased. With such an arrangement, a portion of supercharging air supplied from turbo-supercharger 4 to engine 1 is blown to the exhaust system at the time of idling, accelerating and decelerating engine 1 by opening the control valve 17, thereby enriching the mixture at the time.
