Abstract
An engine ignition system can include a multifunction controller, and an exciter operatively connected to the multifunction controller. The multifunction controller can be configured to control the exciter to output an ignition voltage. The multifunction controller can be configured to perform at least one other engine control function.
Claims21
An engine ignition system, comprising:
- a multifunction controller;
- and
- an exciter operatively connected to the multifunction controller, wherein the multifunction controller is configured to control the exciter to output an ignition voltage, and wherein the multifunction controller is configured to perform at least one other engine control function, wherein the multifunction controller includes one or more ignition step up drivers.

(canceled)
A method, comprising:
- integrating heat sensitive logic components of an engine ignition system in an existing engine controller thereby reducing weight of the engine ignition system and thermally protecting the heat sensitive logic components of the engine ignition system.
An engine ignition system, comprising:
- a multifunction controller;
- and
- an exciter operatively connected to the multifunction controller, wherein the multifunction controller is configured to control the exciter to output an ignition voltage, and wherein the multifunction controller is configured to perform at least one other engine control function, wherein the exciter includes:
- an energy storage device;
- and
- a firing switch connected between the energy storage device and an ignitor output, wherein the firing switch is configured to be controlled by the multifunction controller, wherein the exciter includes a step-up transformer connected between a power supply input and the energy storage device.
