Abstract
A method of responding to a detected blowout in a coil ignition system is provided in this disclosure. The method includes receiving a characteristic regarding operation of a coil ignition system; determining a blowout condition exists for the coil ignition system based on the characteristic; and providing a command to the coil ignition system based on the determination that the blowout condition exists, wherein the command is structured to reduce a residual charge amount in the coil ignition system.
Claims19
An apparatus, comprising:
- a coil signal generator module structured to alternate a leading coil in a multi-coil ignition system each engine cycle;
- and
- a charging module structured to determine whether a coil of the multi-coil ignition system is operational based on operation data regarding the coil relative to an operational threshold when the coil is the leading coil.
A system, comprising:
- a coil ignition system including:
- a first set of primary and secondary coils;
- a second set of primary and secondary coils;
- and
- an ignitor electrically coupled to the first and second sets of primary and secondary coils;
- and
- a controller communicably coupled to the coil ignition system, the controller structured to alternate between the first set and second set of primary and secondary coils as a leading coil for the coil ignition each engine cycle.
A method, comprising:
- alternating, by a controller, a leading coil of a coil ignition system each engine cycle;
- receiving, by the controller, a charging current threshold for the leading coil;
- receiving, by the controller, a time duration for reaching the charging current threshold for a coil of the coil ignition system when the coil is the leading coil;
- and
- determining, by the controller, an operational status of the coil based on the time duration for the coil relative to an operational threshold time duration.
