초록 ▼

In an ignition apparatus for an internal combustion engine, an ECU produces an ignition signal to an igniter/coil circuit with an igniter and ignition coil, which in turn sends back a monitor signal for ignition failure determination in the ECU. The ignition signal and the monitor signal are sent through a single signal line. The monitor signal is produced based on a primary current or a secondary current of the ignition coil.

대표청구항 ▼

An ignition apparatus for an internal combustion engine, which applies a high voltage to an ignition plug of the internal combustion engine, comprising: an ignition coil means having a primary coil and a secondary coil; and an igniter circuit means for connecting/interrupting a supply of an energizing current to said primary coil in response to an ignition signal; wherein: said ignition coil means and said igniter circuit means are assembled as a unit in an integral form, and said unit has a power supply terminal, a ground terminal, a terminal for the ignition signal, and an output terminal to which said ignition plug is connected; said igniter circuit means includes: a semiconductor switching element for connecting/interrupting the supply of the energizing current from said power supply terminal via said primary coil to said ground terminal in response to the ignition signal; a constant current controlling circuit for detecting an energizing current to said primary coil and for blocking an input of the ignition signal to said semiconductor switching element in response to a detected value; and a monitor signal transmitting circuit for detecting an energizing current to said secondary coil so as to determine whether an ignition operation is normal or abnormal, and for transmitting a monitor signal in response to a determination result; said monitor signal transmitting circuit is so arranged that after the ignition signal is ended, a voltage is applied to said ignition signal terminal, whereby said monitor signal is transmitted from said ignition signal terminal; and said igniter circuit means is further comprised of a mask circuit for blocking the supply of the energizing current to said primary coil by said semiconductor switching element while the monitor signal is transmitted.
