PURPOSE:To improve accelerating property by a method wherein a fuel regulator is provided with a driving mechanism, which increases fuel pressure by operating a release valve, while the same mechanism is operated in conjunction with a throttle valve through a link mechanism upon sudden acceleration. CONSTITUTION:In the engine, in which the fuel regulator 13 is provided in a fuel path 10 supplying fuel, delivered by a fuel pump 8 driven by a prime mover 7 together with an air pump 9, into the fuel injection port 12 of an injector 11 provided in a small venturi 4, the fuel regulator 13 is constituted of a fuel chamber 16, partitioned by diaphragms 17, 19 respectively, a vacuum chamber 18 and an air chamber 20. The driving mechanism 34, consisting of two sheets of diaphragms 29, 30, rods 31, 32 and a returning spring 33, is provided at the side of the air chamber 20 while the rod 31 is inserted into the air chamber 20 to approach it to the diaphragm 19. The diaphragm 30 of the driving mechanism 34 is connected to and operated in conjunction with the throttle valve 5 through the link mechanism 35 to constitute the accelerating device. |
