ABSTRACT:
An apparatus for determining the timing of an internal combustion engine having a crankshaft, a camshaft, and a plurality of cylinders each having an electronically controlled fuel injector is disclosed. A crankshaft sensing device monitors the rotation of the engine crankshaft and responsively produces a crankshaft pulsetrain. Additionally, a camshaft sensing device monitors the rotation of the engine camshaft and responsively produces a camshaft pulsetrain. An engine control receives the crankshaft and camshaft pulsetrains, and responsively determines the period of each pulse, determines the rotational position of the crankshaft and camshaft, and produces an inject signal relative to one of the crankshaft and camshaft pulsetrains to the fuel injector in order to initiate fuel injection.
