Internal combustion engine ignition system |
摘要 |
An ignition system for a distributorless internal combustion engine ignition system. Parameters related to the energization of a given ignition coil are stored and later utilized to control the dwell time for this same ignition coil. Another coil is energized and deenergized between the storing of parameters and the subsequent use of the parameters that relate to the given coil. The system causes a spark plug to be fired when a calculated spark timing signal is developed or at a time delayed from the occurrence of the calculated spark timing signal. Delayed spark plug firing occurs when certain conditions are not met prior to the time the calculated spark timing signal occurs. One of these conditions is that primary winding current has not attained a current limit value prior to the time that the calculated spark timing signal occurs.
