摘要： A fuel supply apparatus for internal combustion engines of a type including an air valve disposed in an intake conduit of the engine upstream of a throttle valve. A sensor is used for sensing the pressure in an air pressure chamber defined within the intake conduit between the air valve and the throttle valve and a feedback control unit is used for controlling the air valve in response to the pressure sensed by the sensor in order to maintain the pressure in the air pressure chamber at a preset value. A fuel flow metering valve is disposed in a fuel feed channel leading from a source of fuel under pressure to the intake conduit and the metering value is interlocked with the air valve in such a manner that the opening degree of the fuel metering valve is in proportion to that of the air valve. Also a pressure difference control unit is employed for maintaining the pressure difference of fuel across the fuel metering valve at a preset value, whereby the air-fuel ratio of an air-fuel mixture is maintained constant independently of the engine speed. The fuel supply apparatus of the above type further comprises a variable volume chamber defined by a cylinder and a piston slidably disposed within the cylinder and interlocked with the throttle valve. The pressure variation in the variable volume chamber according to operation of the throttle valve for acceleration or deceleration of the engine is transmitted to either the pressure difference control unit or the air valve control unit to correct the preset pressure difference across the fuel metering valve or the preset pressure in the air pressure chamber, whereby the air-fuel ratio is made richer or leaner during acceleration or deceleration of the engine.

摘要： In a fuel supply apparatus for an internal combustion engine, a fuel discharging apparatus includes a fuel discharge port opened in an air intake conduit and a fuel valve for injecting a controlled quantity of fuel into the air intake passage through the discharge port. An annular fuel whirling chamber is formed around the fuel valve to receive fuel flow in a tangential direction to cause the fuel flow to whirl within the annular chamber. On the other hand, an annular recess is formed in a passage communicating the discharge port and the fuel valve with each other to forcively feed air to the fuel flowing through the passage. The fuel is thus intensively mixed with air and can be easily atomized upon being injected into the air intake passage through the discharge orifice.

摘要： An air-fuel ratio control apparatus for an internal combustion engine has an air valve disposed in an intake passage downstream of a throttle valve to cooperate therewith to define an air pressure chamber and operative to maintain a substantially constant pressure therein. A fuel circuit includes a fuel discharge port open to the intake passage and a fuel-metering orifice operatively associated with the air valve such that the fuel-flowing section of the orifice is varied in proportion to the air-flowing section of the air valve. A constant differential fuel pressure valve is disposed in the fuel circuit to maintain a substantially constant fuel pressure difference across the fuel metering orifice during normal engine operation. The differential fuel pressure valve is mechanically operatively connected to a piston-cylinder assembly into which the fuel pressure upstream of the fuel-metering orifice is introduced. The position of the piston relative to the cylinder is varied when the engine operating condition is varied. The movement of the piston varies the fuel-flowing section of the differential fuel pressure valve thereby to vary the fuel pressure difference across the fuel-metering orifice whereby the air-fuel ratio is varied when the engine operating condition is varied.

摘要： An air-fuel ratio controlling system for a fuel-injection type internal combustion engine has an air valve disposed in an air intake duct upstream of a throttle valve and a fuel-metering variable orifice disposed in a fuel circuit. The air valve and the fuel-metering variable orifice are operatively associated with each other and controlled normally to maintain the air-fuel ratio at a substantially constant value. Pressurized fuel is used as a working fluid to operate the air valve. O.sub.2 sensor detects the oxygen content of exhaust gases to actuate a valve which varies the pressure of the working fluid to change the degree of opening of the air valve whereby the air-fuel ratio is adjusted in accordance with the output of the O.sub.2 sensor.
