- Abstract
Engine cold testing process depends mainly on the feedback of the mounted sensors on the driveline and the engine itself. Feedback signals carry information about the rotating speed, the engine noise and vibration, the manifold pressures, and the torque values. The clarity of these signals affects the accuracy and utility of the cold test during the engine development. The engine, the driveline, and the electric motor system operate at high speeds that generate axial and lateral vibrations. The failure of any part of the assembly distorts the signals and induces backlash or harmonic amplifications. This paper presents results on the harmonic distortions and a methodology to locate and eliminate the mechanical interruption source.
