ABSTRACT:
The present invention concerns a multi-cylinder engine comprising a throttle body (5) in which a throttle intake-air passage (6) is provided. A throttle valve (7) is arranged in this throttle intake-air passage (6). Attached to the throttle body (5) is an injector (8), a leading end portion (9) of which is arranged opposite to an interior area of the throttle intake-air passage (6) downstream of the throttle valve (7) and is opened to provided a liquid-fuel injection hole (10). An intake-air pressure sensor (15) is attached to the throttle body (5) together with the injector (8) and an intake-air pressure introduction passage (18) has an inlet (18a) provided by opening an inner peripheral surface of the throttle intake-air passage (6) upstream of the injector (8).
