For the cylinder power imbalancing/balancing methods proposed earlier in this research work by the authors, measurements of the angular speed of the crankshaft with sufficient quality is essential. In this paper different aspects of speed measurement are presented. A method is in addition is outlined for identification of the torque-noise component due to Quantization noise & Geometric errors in the speed measurement setup. As the influence of mass torque and noise due to geometric noise is constant on the reconstructed oscillating torque for small fuel injection adjustments, the resulting change in the oscillating torque can be directly attributed to the fuel injection and gas torque change. The phase-angle diagram of the engine can consequently be identified through parameter estimation. © 2012 Jordan Journal of Mechanical and Industrial Engineering. Source
