摘要: An injector has a single tapered valve controlling fuel flow to a plurality of outlet passages. The entrance to each outlet passage has an orifice surrounded by a raised valve seat. Each valve seat is separated from the other valve seats by a recessed space. The valve pivots as it is displaced from the valve seat to allow fuel flow through the outlet passages, and is constrained against other motion within the injector. The valve seats are clustered beneath the free end of the valve. The orifices are sized to compensate for the unequal lift of the tapered valve from the valve seats.

摘要: In a fuel injection system for a multi-cylinder internal combustion engine, a plurality of injection nozzles discharge fuel adjacent the engine inlet ports, and a single injector meters the fuel to all of the injection nozzles. The injector may include an annular valve surface, a plurality of discharge passages opening through the valve surface to direct fuel to the nozzles, and a single valve member associated with the valve surface to control fuel delivery to the discharge passages. The injector may include a rectifier valve that admits air to the discharge passages when the valve member precludes fuel delivery to the discharge passages. The fuel discharge lines that connect the injector discharge passages to the nozzles may be surrounded by air lines.

摘要: An electromagnetic fuel injector is provided with a tapered armature valve plate operatively positioned by means of a locator so that it is arranged so as to, in effect, pivot from a spring biased position at which it seats against a valve seat associated with a plurality of orifice discharge passages located concentrically about the axis of the injector to a second position adjacent to the working surface of the pole piece means of the associate solenoid. Preferably, the electromagnetic fuel injector is of the bottom feed type whereby it can be supplied with fuel in excess of the amount to be injected, with the flow path of fuel being arranged so that the excess fuel will purge vapors from the injector and cool the solenoid coil therein.

摘要: A method for recalibration of parametric relationships used in exhaust gas recirculation EGR control. When such recirculation would typically be inactive, relationships between parameters are measured, such relationships being normally measurable only with inactive EGR. New information from those measurements is combined with information from previous calibrations to provide update information necessary for subsequent EGR control.

摘要: A motor vehicle combustion engine has an exhaust gas recirculation system in which the flow of recirculated exhaust gas is controlled through an orifice having exhaust back pressure on one side and a control pressure on the other as determined by an EGR valve. A pressure transducer compares the control pressure with a reference pressure provided in part by an electromagnetic force to provide an operating pressure for positioning the EGR valve to obtain a control pressure equal to the reference pressure. At engine idle, the EGR valve is closed and the control pressure is equal to the exhaust back pressure. When this condition exists, the electromagnetic force is varied until the reference pressure is substantially equal to the control pressure, the magnitude of the electromagnetic force being a measure of the control pressure at idle and which comprises a calibration value that is stored for use as a reference for controlling exhaust back pressure during other engine operating conditions.

摘要: A valve for an automotive vehicle emission system is provided which includes a valve housing with an inlet communicating the valve housing with an air pump; an outlet fluidly communicating the valve with a catalytic converter, the outlet having a check valve preventing flow from an engine exhaust conduit through the valve to the air pump; an upper diaphragm in the valve housing creating a first chamber in the housing which is fluidly exposed to the inlet; a lower diaphragm in the housing creating a second chamber between itself and the first diaphragm, the lower diaphragm forming a third chamber between itself and the housing generally opposite the first chamber; a sealing wall located within the housing separating the second chamber from the inlet, the sealing wall having a surface forming a valve seat with the lower diaphragm, dividing the inlet from the second chamber; a spring urging the lower diaphragm toward the first chamber; and a valve stem connecting the upper and lower diaphragms wherein the air pressure within the lower chamber causes a generally equal force on the upper diaphragm to move in a first direction as it causes on the lower diaphragm to move in a second direction opposite from the first direction, moving the lower diaphragm away from the sealing wall.
