Abstract
An ignition performance increasing method of an automobile may include inputting a crank position sensor signal to detect a rotational position of a crankshaft of an engine, generating an engine angle tick, acquiring an engine synchronization by determining a position of the crankshaft and a position of a cam, setting a sync task at a specified position, and performing fuel injection and ignition.
Claims6
An ignition performance increasing method of an automobile, comprising:
- inputting a crank position sensor signal to detect a rotational position of a crankshaft of an engine;
- generating an engine angle tick which is a rotation angle of the crankshaft per tick;
- acquiring an engine synchronization by determining a position of the crankshaft and a position of a cam;
- setting a sync task at a specified position;
- and
- performing fuel injection and ignition,
- wherein the engine angle tick is generated as a virtual angle until a next crank position tooth is reached, regardless of the engine synchronization
- wherein in the setting of the sync task, a nearest sync task is compared with a current angle
- wherein when the sync task is compared with a current angle and the current angle is equal to or greater than the current angle plus one (“+1”) tooth, a first sync task is set at a point corresponding to the current angle +1 tooth.
