Abstract
A method to deliver spark during a start for an internal combustion engine is described. The method provides individual cylinder spark angle control based on the number of cylinders after synchronization between engine timing and an engine controller are achieved. The method offers improved engine emissions while maintaining engine speed run-up performance.
Claims31
A spark ignition controlling method for an internal combustion engine of a vehicle, comprising:
- counting a number of cylinder events after synchronization between engine timing and an engine controller is determined;
- and
- adjusting cylinder spark angle based on said counted number of cylinder events.
A spark ignition controlling method for an internal combustion engine, comprising:
- counting a number of cylinder events after synchronization between engine timing and an engine controller is determined;
- adjusting a first amount of said cylinder spark angle based on said counted number of cylinder events;
- adjusting a second amount of said cylinder spark angle independent of said counted number of cylinder events;
- and
- delivering spark to the engine based on said first and second amount.
A spark ignition controlling method for an internal combustion engine, comprising:
- counting a number of cylinder events from a start of an internal combustion engine;
- adjusting a first amount of said cylinder spark angle based on said counted number of cylinder events;
- adjusting a second amount of said cylinder spark angle independent of said counted number of cylinder events;
- and
- delivering spark to the engine based on said first and second amount.
A spark ignition controlling method for an internal combustion engine of a vehicle, comprising:
- counting a number of cylinder events after synchronization between engine timing and a engine controller is determined;
- and
- adjusting cylinder spark angle based on said counted number of cylinder events while operator input is substantially zero.
A spark ignition controlling method for an internal combustion engine, comprising:
- counting a number of cylinder events from a start of an internal combustion engine;
- and
- calculating cylinder spark angle based on said counted number of cylinder events while operator input is substantially zero.
A computer readable storage medium having stored data representing instructions executable by a computer to control a spark ignition internal combustion engine of a vehicle, said storage medium comprising:
- instructions for counting a number of cylinder events after synchronization between engine timing and an engine controller is determined;
- and
- instructions for adjusting cylinder spark angle based on said counted number of cylinder events.
