Control apparatus of multi-cylinder engine

摘要

A control apparatus of a multi-cylinder engine (10) includes intake ducts (43A-43D) which supply the air through individual intake ports (17) to a plurality of cylinders (12A-12D) and an Impulse charger (50) which charges the impulse in each cylinder (12A-12D) at halfway points in each intake stroke during each intake valve (19) is opening the corresponding intake port (17), engine speed detecting means (66) which detects an engine speed, engine load detecting means (68) which detects engine load conditions and, control means (100) which controls operation of the impulse charger (50) based on detections by the engine speed and engine load detecting means. The control means (100) operates the impulse charger (50) at a low-speed region at low- and high-load regions except medium-load region at low temperature region including cold-start.
