Title: Ignition device for internal combustion engine
Inventor: ONO TAKASHI
IPC: F02P15/00
Filed: 2008-04-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine which can prevent an IGBT from being brought to the Re-ON position caused by the noise included in an ignition signal.  <P>SOLUTION: By providing an OFF-delay circuit part 15, the first electric potential 16 is made a threshold value as a reference electric potential Vref when a charge electric potential Vc of a capacitor 3 drops. When the charge electric potential Vc rises, the second electric potential 17, which is larger than the first electric potential 16, is made a threshold value as a reference electric potential Vref. Because of this, since only the difference between the first electric potential 16 and the second electric potential 17 can be recharged in excess when the capacitor 3 is recharged, the charge electric potential Vc is prevented from falling short of the reference electric potential Vref (the first electric potential 16) because of the amount recharged in excess even when the charge electric potential Vc has dropped because of noise. Thus, the IGBT 14 can be prevented from being brought to the Re-ON position caused by the noise.  <P>COPYRIGHT: (C)2010,JPO&INPIT
