Fuel intake system for supercharged engine

摘要

A fuel intake system for a supercharged engine including an engine driven supercharger comprises a primary intake passage having a primary throttle valve for controlling the flow of an air-fuel mixture to be supplied to the engine, an auxiliary intake passage having an auxiliary throttle valve for controlling the flow of at least an air supercharged by the supercharger and adapted to be supplied to the engine, and an electromagnetic clutch for initiating and interrupting the transmission of the drive from the engine to the supercharger. The clutch is in position to establish the drive transmission between the supercharger and the engine only during the high load engine operating condition.
