摘要： A transistorized ignition apparatus for driving plural ignition coils of an internal combustion engine comprising two power transistor circuits, each having a power transistor, and a pick-up coil for generating an ignition timing signal synchronized with the rotation of the engine. A wave-form shaping circuit receives the ignition timing signal and determines the conduction period of the power transistors, including the conduction starting point thereof. Two driver circuits, which are provided for respective power transistor circuits, produce driving signals thereto on the receipt of an output from the wave-form shaping circuit. Each power transistor circuit has a current limiter circuit which decreases the base current of the power transistor depending on the amount of the current flowing therethrough. The currents through the power transistors, therefore, are restricted to respective maximum values and the operations thereof are drawn into the non-saturation region. One maximum value is preset lower than the other. A feedback circuit monitors the voltage at the collector of the power transistor, the current through which is restricted under the lower maximum value, and detects the duration of the non-saturated operation thereof. In the wave-form shaping circuit, the conduction period of the power transistors, particularly the conduction starting point, is controlled depending on the output from the feedback circuit.

摘要： An ignition apparatus for a multi-cylinder reciprocating internal combustion engine has a plurality of spark plugs arranged in each of the cylinders with each spark plug having a high voltage generating circuit. The ignition apparatus comprises an ignition signal generating circuit for generating a timing signal in accordance with the rotation of the engine, an actuation signal generating circuit responsive to the ignition signal to actuate the respective high voltage generating circuits to generate high voltages for causing the spark plugs connected to the respective high voltage generating circuits to generate sparks, and a disabling signal generating circuit for generating a disabling signal for disabling the sparking of a selected one of the plurality of spark plugs. The actuation signal generating circuit responds to an ignition signal to apply actuation signals to the corresponding high voltage generating circuits to actuate them to generate high voltages for effecting the sparking of the spark plugs. If a disabling signal is generated, at the time when the one of the high voltage generating circuits corresponding to the selected ignition plug is already supplied with an actuation signal, the actuation thereof is continued until it finishes the ignition and thereafter the application of an actuation signal to the selected high voltage generating circuit is inhibited as long as the disabling signal continues. If a disabling signal is generated at the time when the selected high voltage generating circuit is not actuated, the application of an actuation signal to the selected high voltage generating circuit is inhibited as long as the disabling signal continues.
