Internal combustion engine with supercharger

摘要

An internal combustion engine with a supercharger, for use in a vehicle having an acceleration pedal. A throttle valve disposed in an intake system of the engine is interlocked with the acceleration pedal and is movable between an idle position when the acceleration pedal is in a non-load position and a full-open position when the acceleration pedal is in a predetermined intermediate-load position. The throttle valve is held in its full-open position when the acceleration pedal is between the predetermined intermediate-load position and a full-load position. A control device is interlocked with the acceleration pedal for controlling the operation of the supercharger so as to cause the same to perform its supercharging only when the acceleration pedal is between the predetermined intermediate-load position and the full-load position.
