Informational technology for identity estimation of duty cycles of internal combustion engines

Abstract

Method for identity estimation of internal combustion engines duty cycles based on signal of crankshaft rotational speed deviation processing is proposed. Mechanical system with 10 degrees of freedom as a mathematical model of multi cylinder engine is proposed. A transfer function of cylinders’ contribution to the rotational speed deviation of the first mass is obtained. Method and apparatus for compensation of kinematic error of the instantaneous crankshaft rotation speed sensor is proposed. Informational technology for digital processing of signal of speed and duty cycles identity estimation is developed.
