摘要： The output of an oxygen sensor is fed in parallel to the inputs of amplifiers having amplification in different portions of the sensor output range and having different gain. The amplifier outputs are combined in a summing circuit. The result is to smooth out the characteristic of the measurement and to produce a signal that can drive an indicator to provide a meaningful indication in terms of air number. The temperature of the oxygen sensor must be regulated or compensated for for good results.

摘要： An apparatus is described for the removal of solid components from the exhaust gas of internal combustion engines, in particular for the removal of soot components from the exhaust gases of self-igniting combustion engines. Under the influence of electrostatic fields, the solid components are diverted and carried to a fresh-air current flowing toward the intake side of the engine. This recirculation of the solid components may be effected either by means of the recirculation of a partial flow of the exhaust gas which has been enriched with solid components, in which case the solid components are deflected into this partial flow in an electrostatic field, or these solid components may be guided into the fresh-air current aspirated by the engine, in this case with the cooperation of a mechanical transport means and electrostatic bonding forces.

摘要： A fuel injection pump for internal combustion engines, in particular an in-line injection pump for Diesel engines, is proposed having an injection quantity governor and an electrically driven feed pump, in which in order to assure an emergency shutoff in the event of a malfunction of the injection quantity governor, a check valve, the forward flow direction of which is toward a suction chamber filled with fuel by the feed pump, is disposed between the pressure-side outlet of the feed pump and the suction chamber. An emergency shutoff device responding to a malfunction switches off the feed pump drive, so that because of the lack of feed pressure the check valve closes and blocks off the suction chamber. The engine comes to a stop, as soon as a partial vacuum is established in the suction chamber, which occurs as soon as several revolutions later.

摘要： A method and an apparatus are proposed for determining and controlling an exhaust gas recirculation rate in internal combustion engines (Diesel engines), wherein an adjusting member in the exhaust gas recirculation line is adjusted by a regulator in order to attain precise regulation of the exhaust gas quantity recirculated to the aspirated air zone. The regulator is supplied with the exhaust gas temperature (T4) measured at a given time as the load signal for the engine. The comparison value of the regulator is then either an actual value of the exhaust gas recirculation rate, ascertained by means of effective temperature measurements in the intake zone of the engine, or a set-point differential temperature which is produced by means of measuring the aspirated air quantity at a given time and the rpm.

摘要： A regulator shaft, rotary centrifugal weights, and a governor member which is slidable on the regulator shaft, are arranged in a pressurized, fuel-filled inner chamber of a fuel injection apparatus. The centrifugal weights engage regulator springs via the governor member and a control sleeve. The governor member is closed adjacent the free end of the regulator shaft except for a throttle opening for communication with the inner chamber. The governor member is provided with a work chamber, one extremity of which is limited by the regulator shaft. A conduit leading to a fuel tank communicates with the work chamber. A magnetic valve connected to an electronic control device for control of the fuel flow is provided in the conduit. Opening the magnetic valve causes a pressure drop in the work chamber which in turn causes the governor member to press against the centrifugal weights, thus enhancing the fuel injection quantity so as to reduce deviations from those desired and pre-set.

摘要： A fuel injection device for mixture compressing, externally ignited internal combustion engines, which serves to meter the fuel proportional to the intake air and aspirates the air-fuel mixture. The fuel injection device includes an air flow rate meter located downstream of a butterfly valve in the air induction tube. The bearing shaft of the air flow rate meter includes a fuel metering valve which can be activated directly by the air flow rate meter. To correct the air-fuel mixture because of air density downstream of the butterfly valve, the fuel injection device is so arranged, that when the butterfly valve is in its idling and full load positions a rich air-fuel mixture can be regulated, and when the butterfly valve is in a partial load position a lean mixture can be regulated.

摘要： A fuel metering valve assembly includes an air flow metering member which actuates the movable part of a fuel metering valve. Depending on the displacement of this movable part, two cooperating openings, a control slot and a shaped control orifice, together define the effective flow cross section for the fuel delivered to the engine. In order to improve the resolution of the path of the moving part of the valve assembly, one of the cooperating openings, e.g. the control orifice, is formed as a triangular opening in a sleeve or bushing surrounding an axially slidable shaft which supports the air flow rate-responsive member. The triangular opening may also be defined within the wall of the shaft. The width of the control slot is defined by a spacer ring between two coaxial partial bushings and one edge of the triangular opening is defined by the oblique line separating two partial sleeves.
