Abstract
A fuel dispensing device used in an internal combustion engine comprises a throttle valve, engine operating state sensors, a control circuit producing engine control signals in response to the outputs of the sensors, a pair of intake tubes 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 including a pair of cylindrical atomizer rings disposed in the intake tube pair and a driver for vibrating the atomizer rings in response to a control signal from the control circuit, and a pair of injection valves 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.
