摘要： This invention relates to an apparatus for controlling at least one electrical switching element in internal combustion engines, particularly the main relay of the voltage supply, in accordance with one operating characteristic and with a switch position which indicates an operating condition, in which the signal corresponding to the operating characteristic can be fed to a storage device whose charging and/or discharging process can be influenced by the switch relative to the ignition with the value of the storage signal serving to control the electrical switching element. Furthermore, the signal in accordance with the operating condition and, indirectly or directly, corresponding to the operating characteristic can be fed to a connection point whose output signal can be switched to a switching device for heating the heating wire in an air flow rate meter to a red-hot condition.

摘要： The cyclic control pulses for actuating the fuel injection valves of an internal combustion engine are extended during engine starting at low temperatures. The degree of pulse extension, i.e. of fuel enrichment, is made dependent on engine temperature and decreases as a function of cranking time. In addition, a repeated starting attempt will be accompanied by reduced pulse extension to prevent excessive enrichment of the mixture. The pulse extension may also be retained for a period of time after engine cranking to insure smooth running.

摘要： There is described a method and an apparatus for use with the fuel preparation system of an internal combustion engine, for example, a fuel injection system which operates injection valves with electrical control pulses. When the gas pedal of a vehicle is actuated abruptly, the air flow measuring device of such systems is subject to oscillations around its equilibrium point, and the initial one of these swings is used to cause enrichment of the fuel-air mixture. The return swing generates an undesired lean signal which is suppressed by a "damping circuit". In addition, there is provided mixture enriching during steady applications of the gas pedal by means of a time-decaying enrichment signal generated by a slow acting circuit which operates in superposition to the action of the damping circuit. Both circuits may be suppressed by a blocking circuit during certain engine conditions, for example, during engine starting and engine overrunning as well as on the basis of temperature.

摘要： A method and an apparatus for generating fuel metering control pulse which may be used to control the operation of injection systems, carburetors, or any other controllable fuel metering mechanism. The system includes two signal generators one of which continually generates a signal related to engine conditions while the other is engaged in deriving therefrom a fuel metering control pulse of appropriate length. The duration of the pulses may be obtained by the charging and discharging constant of control capacitors or by a process of numerical countdown of digital data.

摘要： A method and an apparatus for overrunning control in an internal combustion engine are proposed, which operate with an overrunning cutoff and the reestablishment rpm of which is dependent on rpm and on time. At the onset of overrunning, a higher reestablishment rpm is selected, and once the rpm falls below a predetermined rpm value the reestablishment rpm is reduced according to a time function to a lower threshold value. The method may be realized by a controlled system, as well as by a control apparatus operating with analog circuitry.

摘要： A fuel mixture control apparatus for an electronic fuel injection system for internal combustion engines. In a warm-up controller, the fuel injection control pulses are lengthened for enrichment of the fuel-air mixture during engine warm-up on the basis of signals supplied by a temperature transducer. In order to make the warm-up enrichment dependent on prevailing engine states, for example on the conditions of idling and partial or full load, circuitry is provided to sense these conditions and to suitably alter the enrichment factor. A further circuit suppresses the dependence or enrichment on engine status during engine starting. Various embodiments are presented.

摘要： A control circuit of a fuel management control system for internal combustion engines monitors the operation of an exhaust line sensor. When the oxygen sensor is perceived to be inoperative, for example, due to low ambient temperature, the previously closed loop control process governing the fuel management control signals is interrupted and a direct forward control process is substituted therefor. The reference voltage is changed during this time for eventual adaptation to the changeover to closed loop feedback control after the oxygen sensor again becomes operational.
