Claims20
A sensor for indicating the phase of an internal combustion engine comprising an engine output shaft, a camshaft, means for driving said camshaft from said engine output shaft, said camshaft having at least one lobe thereon for operating a poppet valve of said engine, and a sensor fixed to said engine in proximity to said cam lobe for providing an output signal when said cam lobe passes said sensor.
A cylinder head arrangement for an overhead valve, internal combustion engine having an output shaft, a camshaft journalled in said cylinder head and having a cam lobe for operating at least one valve therein, means for driving said camshaft from said engine output shaft at one half engine output shaft speed, a cam cover affixed to said cylinder head and enclosing said camshaft, and a sensor carried by said cam cover and in proximity to said cam lobe for providing an output signal when said cam lobe passes said sensor.
