Abstract
PURPOSE: To eject fuel without pulsation, by providing a regulator means for eliminating pulsation of fuel and a control circuit section for controlling the valve opening time of a metering valve in accordance with the amount of intake air, in a mixture supplying system comprising an electromagnetic metering valve and a regulator means.
CONSTITUTION: Fuel is supplied from fuel tank 13 and pressurized by pump 11 after passing through filter 12. Then, fuel is carried into regulator 10 which functions to keep fuel pressure Ps at the inlet of electromagnetic metering valve 6 constant. Control circuit 14, receiving signals from pressure sensor 15 and ignition coil 16, calculates the quantity of intake air from the product of pressure PB in the intake pipe and engine speed Ne and indicates to metering valve 9 an appropriate valve opening time τ suited to the quantity of intake air thus calculated. With such an arrangement, fuel is supplied intermittently into regulator chamber 8 and fuel pressure is controlled therein such that pressure difference with respect to pressure at the inlet of carburetor is kept constant Pa. At the same time, pulsation of fuel is absorbed in chamber 8, so that fuel is ejected from nozzle 6 uniformly in an analogous manner free of pulsation.
