摘要

Method for Predicting the Rpm Regimen of an End-of-Stage Engine Crankshaft and Using Said Method for Predicting the Rpm Regimen of an End-of-Stage Engine Crankshaft The invention relates to a method for predicting the speed of rotation of a crankshaft (2) of an engine (1) in the final phase of rotation so that the actual crankshaft rotation speed (n) is determined and recorded by a crankshaft angular position path (t) (2), said path being defined by a first and second angular position; a constant (co) being determined on the basis of current velocities determined by the first and second angular positions, and a predicted rotational speed (n) being determined by a third angular position, which is not included in path (t), based on the constant and current velocity (n) which is determined by a fourth angular position included in said path and such that the spacing between the third and fourth angular positions is a multiple greater than or equal to said path. The invention also relates to the use of the method for predicting the stop cylinder.
