  • Method and system for determining cylinder position with an internal combustion engine
    Patent number: 7058500
    Abstract: An internal combustion engine having a crankshaft rotatable within an engine block of the engine and at least one camshaft driven by the crankshaft. The crankshaft is fixed to a crankshaft wheel having a plurality of crankshaft wheel marks and at least one crankshaft position indicia. The camshaft is fixed to a camshaft wheel having a predetermined pattern of camshaft wheel marks. A crankshaft sensor is fixed to the engine block for producing a crankshaft signal in response to detection of the crankshaft position indicia. A camshaft sensor is fixed to the engine block for producing camshaft signals in response to detection of the camshaft wheel marks. Rotation of the crankshaft generates a pattern comprising the crankshaft signal and the camshaft signals. A processor compares the generated pattern to a stored reference pattern for determining from such comparison the position of the crankshaft within the engine block.
