PURPOSE:To improve the volume efficiency and combustion efficiency of an internal combustion engine by installing a device for feeding the finely atomized water into an intake passage on the upstream side of a throttle valve and varying the mist generation quantity according to the opening/closing operation of the throttle valve. CONSTITUTION:On the downstream side of an air cleaner 8 and on the upstream side of an intake manifold 1, an injection hole unit 9 which consists of an annular hollow body and has a plurality of injection holes 9b formed on the inner peripheral wall is installed. One edge of a mist introducing pipe 10 is connected to one position on the outer peripheral wall of the injection hole unit 9, and the other edge of the mist introducing pipe 10 is connected with a water level adjusting container 11 having a rectangular parallelo piped form. Water is supplied from a water pump 14 into the container 11, and the water level is always kept at a prescribed level by the action of a float 12. A vibrator 17 with which a supersonic wave oscillation circuit 16 is connected is installed on the bottom part of the container 11, and the mist generation quantity is varied by controlling the oscillation intensity of the vibrator 17 on the basis of the output of a variable resistor 12 for detecting the operation of a throttle valve 2. |
