Abstract
In one embodiment, the present invention is directed to a method of igniting a fuel charge of a Gasoline Direct Injection engine. The method of this embodiment includes providing an ignition pulse to an ignitor, the pulse having a duration of at least 1 μs and an average power of at least 500W.
Claims22
A method of igniting a fuel charge of a Gasoline Direct Injection engine comprising:
- providing an ignition pulse to an ignitor, the pulse having a duration of at least 1 μs and an average power of at least 500W.
2 The method of claim 1, wherein the step of providing includes providing the ignition pulse such that it has a peak power of 1500W sustained for at least 0.5 μs.
A method for adjusting a Gasoline Direct Injection engine timing comprising acts of:
- (a) setting the ignition timing at a fixed delay from the injector timing;
- (b) following act (a) adjusting the injector timing relative to the crank angle until the desired ignition timing relative to the injection timing is achieved.
A method of operating a Gasoline Direct Injection engine comprising, in sequence, acts of:
- (a) determining a time when the fuel injector changes state;
- (b) delaying for a predetermined time;
- and
- (c) triggering an ignition sequence after the delay.
A method of operating a Gasoline Direct Injection engine comprising:
- coupling the ignition timing directly to the injector signal;
- and
- adding a delay, wherein the delay is greater that or equal to 0.
