Abstract

PURPOSE: To promote the atomization of fuel for economizing the fuel cost greatly and promoting the combustion efficiency by regulating the discharge of suction air according to opening degrees of a butterfly throttle valve and a variable Venturi tube arranged in parallel in a suction pipe.
CONSTITUTION: In this fuel supply unit for a gasoline engine, fuel is injected into a suction manifold by a positive pressure after being measured by a fuel discharge control system composed of an air discharge measuring unit 1 and a fuel discharge measuring unit 2. Here, a butterfly throttle valve 5 and a variable Venturi tube 19 are equipped in parallel in an air suction pipe 6 for regulating the discharge of suction air for an engine by adjusting their opening degrees respectively. Besides, under the condition of a partial load operation with less discharge of suction air for the engine, the variable Venturi 19 tube is solely used.
