摘要： PURPOSE:To facilitate the varying control of fuel pressure in accordance with the operating condition of an engine by providing a hollow cylinder type valve seat on a diaphragm which is displaced in accordance with the operating condition of said engine and engaging plural springs with said diaphragm. CONSTITUTION:First and second diaphragm 16, 26 are provided interposing a partition wall 15a in between, in a fuel pressure regulating device 14. A first spring 21 presses a valve member 18 against a valve seat 22. And, due to the opening/closing action of the valve member 18, the fuel pressure of a first chamber 19 is kept at a first set value determined by the first spring 21. The rise in temp. of a fuel injection valve 7 is detected by a temp. sensor 8, causing an electronic control device 34 to drive an electromagnetic selector valve 33, thereby, switching over the pressure of an air chamber 27 to the atmospheric pressure. As a result, the valve seat 22 is moved and the fuel pressure in the chamber 19 is increased. Thereby, the varying control of fuel pressure can be easily carried out in accordance with the operating condition of an engine.

摘要： PURPOSE:To aim at obtaining a high output power with one single large diameter intake-air passage and as well to enhance the control accuracy of air-fuel ratio in a range where the amount of intake-air is small, by providing venturies and a throttle valve in an intake-air passage so that the flow rate of fuel and the amount of intake-air are controlled by pressurized air controlled by a single solenoid valve. CONSTITUTION:Ventureis 3, 4, a throttle vavle 5 and an injection valve 11 are disposed in an intake-air passage 2. A solenoid valve 15 is controlled by an operating condition signal received by a control unit 47. Upon starting the solenoid valve 15 is opened so that pressurized air is fed through an air passage 27 to a control chamber 20 in a fuel regulator 13 to decrease the opening degree of a relief valve 23 so that the injection amount of fuel from a fuel injection port 12 is increased. Further pressurized air introduced into a control chamber 40 in an intake-air controller 39 through an air passage 29 is decreased so that the opening degree of a throttle valve 5 is increased by means of a cam 45. An air regulator 14 controls the pressure of air pressurized by an air pump 9.

摘要： PURPOSE:To stably supply fuel to an engine over its running range from idling to supercharge, by introducing the pressure in the downstream of a throttle valve to a fuel pressure regulator of a fuel injection device in the upstream of the throttle valve so as to change a regulating reference pressure in accordance with the operating condition of the engine. CONSTITUTION:An injector 4 is provided in the upstream of a throttle valve 5 in an intake pipe 22, and the intake pressure is introduced from the downstream of the throttle valve 5 through an intake pressure introducing pipe 21 to a fuel pressure regulator 20 connected to a fuel pipe 8 and a fuel return pipe 9. Size of a gap G in the pressure regulator 20 is determined in such a manner as to be balanced with tension of a spring S, holding fuel in the periphery of the injector 4 to a fixed pressure P2. At a low load when an intake pressure P1 is negative with a small opening of the throttle valve, the fuel pressure P2 decreases with a small injection pressure of the injector 4, decreasing an injection amount per unit time while increasing a fuel injection time. In this way, control accuracy of a flow can be enhanced.

CONSTITUTION:A partially protruded part, in which a fuel injection part 11 forming a small venturi 12 is provided, is provided in a suction air passage 2 at a location between a venturi part 4 and a throttle valve 3. An auxiliary throttle valve 10 is provided in the suction air passage 2 at a location near the fuel injection part 11 and formed in the sectional form of the suction air passage 2 with the part of the fuel injection part 11 is removed so as to clog the greater part of the suction air passage 2 during the running with small suction air quantity, resulting in passing the suction air through the small venturi part 12 and consequently accomplishing the atomization of fuel. Furthermore, an auxiliary throttle valve shaft 9 and a throttle valve shaft 8 are coupled with each other by means of a link mechanism 15, resulting in rendering not to change the opening of the auxiliary throttle valve due to vibration.
