Abstract
An apparatus for controlling the atomization of fuel in an electronically fuel injection device for internal combustion engine, by jetting air or exhaust gas into the injection device so as to mix the air or the exhaust gas with the fuel thereby to atomize the fuel. The apparatus has a regulator adapted to maintain the pressure of the air or the exhaust gas at a level higher than the pressure in the main air passage by a predetermined pressure. The regulator has a housing in which a back pressure chamber and a control chamber are defined at both sides of a diaphragm accommodated by the housing. The back pressure chamber receives the air pressure transmitted from the downstream side of a throttle valve and accommodates a spring which urges the diaphragm toward the control chamber, while the control chamber receives the air from the upstream side of the throttle valve or the exhaust gas. A valve operatively connected to the diaphragm opens and closes the passage between the control chamber and the fuel injection device thereby to control and regulate the pressure of the air or the exhaust gas supplied to the fuel injection device.
