摘要： PURPOSE:To prevent misfire and keep revolving performance of internal combustion engine, by arranging for output transistor to move to off gradually. CONSTITUTION:After transistor 11 is set to off, collector voltage of output transistor 5 gradually descends to zero. Then, condensor 15 is charged by circuit made of resistor 12, diode 17 and output transistor 5. After charging, positive polarity is given to connecting side to collector of transistor 11. As stated, collector voltage of output transistor 5 gradually descends when transistor 11 moves from on to off, and therefore voltage of very few positive polarity only generates in secondary coil of ignition coil 4. This almost perfectly prevents misfire which may generate when transistor 11 moves from on to off.

摘要： PURPOSE:To simplify a circuit for an ignition device having a plurality of power transistors therein and reduce its cost by connecting the emitters of the power transistor in common which are connected in turn to a resistor for detection of an electric current. CONSTITUTION:An ignition coil 7 has a primary winding 7a which are divided into two by a centertap 7c and a secondary winding 7b. Collectors of power transistors Tr5, Tr6 are connected to opposite ends of the primary winding 7a of the ignition coil 7 while emitters of the transistors Tr5, Tr6 are connected in common. A resistor 21 for detection of a primary electric current is interposed between the emitters thus connected in common and the negative electrode of a power source 12. An electric current control circuit is provided which controls the transistors Tr5, Tr6 so as to effect feedback control of the primary current in accordance with the primary current detected by the resistor 21, and ignition signal generators 1, 2 are further provided for generating an ignition signal for bringing the transistors Tr5, Tr6 out of conducting conditions at different ignition timings.

摘要： PURPOSE:To prevent after-burning or the like by discriminating the presence of accidental fire according to the signal of an ignition coil in an ignition system and producing data to nullify the effect of injection upon judging the presence of the accidental fire irrespective of calculated data of the injection amount, so that the fuel injection may be cut off. CONSTITUTION:When an engine is controlled by means of a microcomputer, each output from an A/D converter unit 104 and number of revolution counter unit 102 connected to each of sensors 1-3, those of intake amount, water temperature and intake air temperature is first incorporated in CPU100 to calculate fuel injection amount and ignition timing and write them in a memory unit 105. Next, the stored data are read out to send the output to a digital output unit 106 when instruction signals are supplied from an interrupting unit 101. Then, it is judged whether or not signals representing normal ignition in a latch circuit 110 are supplied, and the data for nullify the effect of injection are transmitted to fuel injection it an accidental fire occurs in an ignition system and the latch input is absent.
