Abstract:
A method of synchronizing an ignition system, a fuel system, and an engine of a vehicle comprising:determining a crankshaft position; determining a camshaft position; identifying a reference engine cylinder in response to said crankshaft position and said camshaft position; determining at least one synchronization value in response to said crankshaft position and said camshaft position; enabling said ignition system and said fuel system in response to said at least one synchronization value and said reference engine cylinder; sensing a crankshaft rotation rate; and determining said at least one synchronization value in response to said crankshaft rotation rate comprising; determining an ignition system synchronization value in response to said crankshaft position and said camshaft position; and determining a fuel system synchronization value in response to said crankshaft position and said camshaft position; and enabling a fuel tank solenoid and a fuel rail solenoid in response to said crankshaft rotation rate.
