Abstract
A fuel supply system for an automotive engine is provided in which fuel is injected from fuel injectors (31a to 31d) into the air that is drawn into the engine (30) through an intake passage (120) to produce a mixture of fuel and air; a microswitch (80) detects that the opening angle of a throttle valve (60) is equal to or greater than a predetermined opening angle, and then outputs a detection signal; a drive motor (110) is operated by a motor control circuit (90) on the basis of the output signal of an air flow sensor (20); and the air drawn into the intake passage (120) is compressed by an axial flow turbo fan (107) driven with the drive motor (110) and is supplied to the engine (30).
