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 ( 18 a) provided by opening an inner peripheral surface of the throttle intake-air passage ( 6 ) upstream of the injector ( 8 ).
