    摘要: In a device for adjusting the injection timing in a diesel engine fitted with EDC, a basic value (SBGWs) of injection timing for operation in the static or steady state is stored in a first characteristic field (20) and a basic value (SBGWd) for operation in the dynamic or unsteady state such as acceleration and deceleration is stored in a second characteristic field (22). These basic values are dependent on desired injected fuel quantity (Q) and engine speed (n). The characteristic field (20) for the static state is designed empirically or otherwise to optimize fuel consumption whereas the characteristic field (22) for the dynamic state is designed for minimum pollutant emission. A gradual changeover from one mode to the other is achieved by the gradual change of a multiplying factor (c) from 0 to 1 or vice versa responsively to dQ/dt departing significantly from zero or becoming zero.

    摘要: The invention is directed to a safety arrangement for an internal combustion engine having self-ignition where, in the sense of an overall system monitoring, specific signals relating to the operating conditions of the internal combustion engine are continuously monitored. These signals are indicative, for example, of the position of the throttle pedal, the computed rack-travel nominal or desired value, and the rotational speed. The monitored signals are processed and a corrected rack-travel nominal value is generated by means of a minimum-value selection circuit. The corrected rack-travel nominal value signal generated in this manner is fed to the rack controller of an EDC unit. At the same time, a deviation in rack travel is determined utilizing the corrected rack travel nominal value in combination with an actual-value signal of the rack travel fed back from the rack-travel sensor. The signal indicative of actual rack travel also serves for a comparison with the upper and lower limits of the rack-travel sensor voltage; and, depending on the error condition occurring, either the output stage of the rack controller is de-energized and/or the fuel-injection pump is simultaneously shut off by means of an electrical shutoff valve (ELAB); or, a decision for an emergency operation is made.

    摘要: The invention is directed to a method for determining the full-load limit of an internal combustion engine wherein a limit surface of a predeterminative full-load characteristic field is shifted to thereby compensate for the manufacturing tolerances occurring in the production of the internal combustion engine. The embodiment described relates to a diesel engine equipped with an electronic control unit. The full-load characteristic field of this internal combustion engine includes a smoke limit surface, an exhaust gas temperature limit surface and a combustion pressure limit surface. A further limit surface of constant torque is added to these limit surfaces. In order to provide for compensation of the manufacturing tolerances occurring in the production of internal combustion engines, the constant torque limit surface is shifted so as to possess a specific predeterminative value. In the subsequent operation of the internal combustion engine, a minimum value selection takes place so that at a specific air quantity always the smallest fuel quantity defined by one of the limit surfaces is injected into the internal combustion engine. An apparatus for carrying out the method of the invention is also disclosed.

    摘要: In a turbocharged diesel engine (10), the charging pressure P.sub.La is adjusted to run the engine (10) with an empirically determined optimum fuel consumption. A charging pressure feedback signal P.sub.La is fed to a regulating device (40) which receives various operating parameters, including ME.sub.d which represents the power output. A characteristic field in a memory zone (50) in the regulating device (40) determines a control variable (TV) which operates a turbine by-pass valve (22) via an electro-pneumatic converter (28) and a penumatic (vacuum) actuator (26). The characteristic field is such that the charging presssure P.sub.La is reduced in the part load range (cruising speed) to improve fuel consumption.

    摘要: Sensors for motor vehicles emit a base signal when the variable which they measure takes on a base value. For example, a road-speed transducer supplies no pulses when either the vehicle is at standstill or when the sensor is defective. A method for providing a reliable operation of a motor vehicle includes the step of starting a substitute/emergency-function immediately when only the base signal is received from the sensor. If it is later determined that the base signal was only emitted because the measured variable took on its base value, then the substitute/emergency-function is again reversed. By starting a substitute/emergency-function basically always when a checked sensor emits no signal, it is ensured that safety measures are taken as rapidly as possible.

    摘要: The invention is directed to a safety arrangement for an internal combustion engine with self-ignition such as a diesel engine or the like wherein the operational signals of throttle position, rack travel and rotational speed are continuously monitored and compared with upper and lower limit values for these signals. From this comparison, comparison signals are generated and are combined with each other to provide an overall monitoring of the operation of the diesel engine so that the latter can be shut off when impermissible ranges of operation are present or, if conditions permit, the engine can be switched to an emergency mode of operation so that the motor vehicle may be driven to the next service station for repair.
