    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: To provide for rapid interruption of the combustion process in an internal combustion engine, for example by inhibiting ignition or supply of fuel by a fuel injection system, speed pulses are integrated and the integrated signal evaluated with respect to a reference to determine whether the integrated signal, and hence the speed of the engine, exceeds a predetermined level; a timing circuit is connected to the evaluation circuit to provide a control signal for a predetermined time interval to inhibit fuel combustion of the engine for the predetermined time interval in case the speed is exceeded. If fuel injection pulses are to be inhibited, then the timing of the timing circuit is synchronized with the fuel injection pulses to provide for complete suppression thereof without pulse overlap.

    摘要: To prevent generation of a spurious spark at the spark plug if the distributor braker control assembly should have commanded an ignition control transistor to be conductive and when the ignition switch is disconnected under those conditions, thus cutting off power to the ignition control transistor rendering it non-conductive and causing spurious voltage pulses which results in a spark at the ignition, a control path is provided connected to a control transistor for the actual ignition transistor and connected in circuit with the current flow due to the energy stored in the ignition coil to control the emitter-collector path of the ignition switching transistor to continue to remain conductive for a short period of time to drain off the stored energy in the coil, although the main ignition switch has been opened.

    摘要: To prevent a spurious inductive spark when the master ignition switch of the vehicle is opened with the breaker terminals closed, so that current stored in the ignition coil might cause a spurious inductive voltage pulse, a protective circuit branch is connected in parallel across the primary of the ignition coil and includes an auxiliary semiconductor short-circuiting switch, preferably a thyristor, the conduction of which is controlled to close by an auxiliary control circuit which senses opening of the master ignition switch and permits application of a portion of the inductive current flow to the gate of the thyristor to render it conductive, thus short-circuiting the primary of the ignition coil and preventing an inductive voltage kick which might cause a spurious spark.
