Analytical and Experimental Model of the Diesel Injector
An analytical-experimental model has been proposed to determine sac volume pressure changes and fuel doses injected into the diesel cylinders. The model takes into account friction forces and the mechanical properties have been identified. Engine performance results have been analysed statistically....

| Sumario: | An analytical-experimental model has been proposed to determine sac volume pressure changes and fuel doses injected into the diesel cylinders. The model takes into account friction forces and the mechanical properties have been identified. Engine performance results have been analysed statistically. The results of the Lilliefors, Pearson, Shapiro-Wilk and Jarque-Bera tests have provided evidence to reject, under certain engine operating conditions, the hypothesis about the compatibility of the measurement data with the normal distribution. Measurement uncertainty for the injector needle lift has been estimated. The difference between the measured and predicted fuel dose values have amounted to approximately 3 %. |
