  • Generating a once-per-cycle signal for a locomotive diesel engine
    Patent number: 5428992
    Abstract: A locomotive diesel engine test assembly generates a once-per-cycle signal phased to the top dead center of a predetermined piston in its cylinder. A locomotive diesel engine crankcase door is hermetically attached to the crankcase so as to cover a camshaft located therein. An outer tube extends through and is hermetically and fixedly attached to the crankcase door, and an inner tube extends through and is hermetically and pivotably attached to the outer tube. A proximity sensor is attached to the inner tube and positioned near and generally perpendicular to the camshaft. A marker is attached to the circumference of the camshaft and is detectable by the proximity sensor once per revolution of the camshaft.
