    摘要： A fuel dispensing device used in an internal combustion engine comprises a throttle valve (7), engine operating state sensors (15,16,17,18), a control circuit (14) producing engine control signals in response to the outputs of the sensors, a pair of intake tubes (6) connected to an intake passage on the downstream side of the throttle valve. with each of the tubes branching at its downstream end into two parts connected to two of cylinders of the engine, an atomizer (10) including a pair of cylindrical atomizer rings (11) disposed in the intake tube pair and a driver (12) for vibrating the atomizer rings in response to a control signal from the control circuit, and a pair of injection valves (9) disposed by the respective atomizer rings. The injection valves operate to inject the fuel in response to the control signal onto the inner wall of the respective atomizer rings, so that the fuel is atomized by the vibration of the atomizer rings, while intermixing with air, and delivered to the respective cylinders.

    摘要： The invention relates to an air-fuel ratio controlling method and a device for internal combustion engines, having a detector (11) for a flow rate of the air supplied into a cylinder (4), a means (7) for detecting a ratio of a flow rate of the air supplied into the cylinder (4) to that of a fuel supplied thereinto, a control means (8) for setting an air-fuel ratio to an optimum level on the basis of output signals from the air-fuel ratio detecting means (7) and air flow rate detector (11) and a means (9) for controlling the supplying of the fuel into the cylinder in accordance with an output signal from the air-fuel ratio control means. The air-fuel ratio detecting means (7) has members for detecting the light generated by a flame in the cylinder and having at least two special wavelengths. The combustion condition corresponding to an air-fuel ratio in the cylinder is detected by the light-detecting members, and a signal representative of an actual air-fuel ratio is generated on the basis of outputs therefrom.
