Patent ID: 8725390

Claim:
A system for optimizing fuel injection in an internal combustion engine, the system comprising: a control circuit having a processor, a memory, and an input/output interface, wherein the control circuit: adjusts start of fuel injection from a source angle to a destination angle; calculates whether one of advancing or retarding the start of injection will provide a shortest path from the source angle to the destination angle; determines, based on the source angle and a given injection pulse width and angle increment, whether fuel injection will overlap with a specified engine event if start of fuel injection is moved in a direction of the shortest path; sends a signal via the input/output interface to increment start of fuel injection in the direction of the shortest path if it is determined that fuel injection will not overlap with the specified engine event; and sends a signal via the input/output interface to increment start of fuel injection in a direction opposite that of the shortest path if it is determined that fuel injection will overlap with the specified engine event.
