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.

Method and system for determining cylinder position with an internal combustion engine

A system for controlling a fuel injector in accordance with an injection control strategy for an engine includes programmable control logic to provide selectable threshold signals for comparator circuits and/or control logic configured to receive various control signals in the control circuit and determine one or more timing signals. The programmable control logic allows the drive circuit to be modified, without changing any hardware, to accommodate injectors having different characteristics and to change the pulse modulation strategy. The control logic that receives the control signals produces injection timing signals to allow enhanced monitoring and control over the fuel injection process.

An improved key and lock assembly in which an electronically coded circuit is embedded in the handle of a conventional key and at least one electrical terminal extends from the handle adjacent to and electrically isolated from the key shank so as to contact a similarly located and biased terminal on the lock assembly when the key is fully inserted therein.
