    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: 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 fuel injection control system generates control pulses which open the fuel injection valves of the engine. The pulse duration is proportional to the injected fuel quantity and can be altered in dependence on air temperature by a circuit which includes a temperature-sensitive resistor. The voltage at this resistor controls a transistor which supplies a supplementary charging current for a timing capacitor.

    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 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 injection system of an internal combustion engine generates valve-actuating pulses for actuating electromagnetic fuel injection valves. The length, or duration, of these valve actuating pulses is a function of various engine conditions and they are generated by a pulse-length multiplying circuit from preliminary control pulses derived from two basic engine variables, e.g. engine speed and air flow rate. In order to compensate for the decreasing pressure drop across the injection valve orifice at high engine load due to increasing manifold pressure, the invention describes methods for lengthening the fuel valve-actuating pulses by engaging the pulse-length multiplying circuit, in order to change the charging or discharging times of the timing capacitor therein. Another method proposed is to engage the battery-voltage compensation circuit in the system to lengthen the valve-actuating pulses. Electronic circuitry to perform these corrections is also described.
