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 dual fuel supply system for an automotive engine has a fuel tank adapted to contain both methane and propane at pressures up to 17,000 kPa. A switching valve assembly directs methane to the engine fuel metering apparatus when the fuel tank pressure exceeds 1400 kPa and directs propane to the engine fuel metering apparatus when the fuel tank pressure is less than 1400 kPa.

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.

摘要： Control of a fuel rate and an air rate delivered to an exhaust gas heater over successive control periods by determining and periodically updating a desired heater air quantity and a desired heater air/fuel ratio, by commanding an air rate in accord with the desired heater air quantity, by adjusting the commanded air rate in accord with a sensed actual air rate, and by commanding a fuel quantity in accord with the desired heater air/fuel ratio and the sensed actual air rate or the desired heater air quantity. A quantity of excess fuel is purged from the system at the end of a control period and provided in usable form to the engine. Compensation for fuel residue in the system is made at the start of subsequent control periods.

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： A pressure transducer of the manometer type comprises two interconnected columns of liquid with means for applying differential pressure across the columns. The liquid is a magnetic liquid and a magnetic field is impressed on the columns to attract the liquid by magnetic force to a reference position. The applied differential pressure acts counter to the magnetic force to shift the columns so that their difference in lengths reflects the pressure. By using capacitor plates to define the walls for the liquid columns and a magnetic liquid which is a dielectric, the capacitance between the plates is a function of the column lengths and therefore is a function of the applied differential pressure.
