An engine control system ( 1 ) measures an amount of air sucked by an engine ( 2 ) based on the output of an air flow meter ( 14 ) provided in an air intake passage ( 4 ), on the downstream side of a throttle valve ( 12 ), calculates an injection amount of fuel based on the air amount measured, and injects the fuel from an injector ( 5 ). The air flow meter ( 14 ) is installed at a position on the downstream side of the throttle valve ( 12 ), away from the valve ( 12 ) by a predetermined distance corresponding to twice to four times the diameter of the air intake passage ( 4 ).
