摘要： PURPOSE:To eliminate the temperature dependency of fuel injected from an injector, by providing a bypass passage bypassing between the upstream and downstream sections of a fuel pressure regulator to surely discharge air bubbles arises in the vicinity of the injector. CONSTITUTION:An injector 4 receives a fuel fed under pressure from a fuel pump through a fuel inlet port 5, and a fuel pressure regulator 6 regulates the fuel at a substantially constant pressure. The fuel is then injected from the injector 4 in which the time and cycle of opening of a valve are determined in accordance with the operating data of the engine. Above the outer periphery of the fuel pressure regulator 6 there is provided a passage 14 bypassing between the upstreamd part 13 and the downstream part (fuel outlet port 12). Further, a valve 16 integrally incorporated with a bimetal 15 opens in accordance with the temperature condition surrounding therearound so that air bubbles is discharged together with fuel from the outlet port 12 through the passage 14 bypassing the fuel pressure regulator 6. With this arrangement the temperature dependency of fuel injected from the fuel pressure regulator may be eliminated to enhance the control ability of air-fuel ratio.

摘要： PURPOSE: To prevent the fly-up phenomenon of the injected fuel and improve the atomizing property as well as the responding property of the device by a method wherein the sectional area of the path of a venturi part, into which a fuel injection valve is inserted, is made larger than the same of the periphery of a throttle valve under fully opened condition thereof simultaneously with the opening of the outlet port of a bypass air path.
CONSTITUTION: A part of suction air passes through the bypass air path 10 and is entered into the venturi part through outlet ports 8. Fuel, supplied from the fuel injection valve 9, is atomized and mixed with the suction air simultaneously when it is injected into the stream of the suction air, then, is sucked into the engine after passing around the throttle valve 5. When the engine is brought into a high-load operating condition and the throttle valve 5 is set at the fully- opened condition as shown by a broken line, a vacuum at the downstream of the throttle valve 5 becomes higher than the same generated in the venturi and the atoms of the fuel, injected from the injection valve 9, passes around the throttle valve 5 regularly without being flown up, thereby improving the atomization as well as the promotion of the supply of the fuel.

摘要： PURPOSE:To stabilize the supply of fuel injected from a main nozzle to improve Venturi performance by specifying the area ratio of each Venturi. CONSTITUTION:A carbureter 1 is provided in an intake path 2 with a large bore Venturi 5, medium bore Venturi 4 and small bore Venturi 3. Assuming the respective projected areas of Venturis 3-5 as S1-S3, these area ratios are set to S1/(S1+S2+S3)>0.1, S2/(S1+S2+S3)>0.2.
