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.
Claims20
An apparatus, comprising:
- a blowout module structured to:
- receive a characteristic regarding operation of a coil ignition system;
- and
- determine a blowout condition exists for the coil ignition system based on the characteristic;
- a residual charge module structured to provide 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.
A system, comprising:
- a coil ignition system including:
- a first set of primary and secondary coils;
- a second set of primary and secondary coils;
- a first high voltage diode electrically coupled to the first set of coils;
- a second high voltage diode electrically coupled to the second set of coils;
- and
- an ignitor electrically coupled to the first and second diodes;
- and
- a controller communicably coupled to the coil ignition system, the controller structured to:
- receive a characteristic regarding operation of the coil ignition system;
- determine a blowout condition exists for the coil ignition system based on the characteristic;
- and
- provide a command to the coil ignition system based on the determination that the blowout condition exists, wherein the command is structured to reduce an amount of residual charge in the coil ignition system.
A method, comprising:
- receiving, by a controller, a characteristic regarding operation of a coil ignition system;
- determining, by the controller, a blowout condition exists for the coil ignition system based on the characteristic;
- and
- providing, by the controller, 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.
