PROBLEM TO BE SOLVED: To provide an engine capable of performing the fine control of fuel feeding corresponding to a load. SOLUTION: In the engine, a throttle valve 7 is arranged in a predetermined intake passage 6, a passage entrance 18a of an intake pressure introduction passage 18 is opened at the inner peripheral surface of the predetermined intake passage 6, and the intake pressure of the predetermined intake passage 6 is introduced to an intake pressure detection sensor through the intake pressure introduction passage 18. The intake pressure detection sensor and an engine revolution number detection sensor are cooperated with the fuel feeding means through a control means, and the fuel in an amount corresponding to the intake amount is fed from the fuel feeding means to intake air by the control means based on the detection of the intake pressure of the predetermined intake passage 6 and the number of revolutions of the engine. The annular inner peripheral surface of a predetermined width of the predetermined intake passage 6 is made to be a venturi part 6i, and a passage entrance 18a of the intake pressure introduction passage 18 is opened at the venturi part 6i.
