Method for controlling of smooth running of reciprocating engines, involves selection of order so that odd multiple of half camshaft frequency with in row representation is taken into consideration, for generation of control divergence

摘要

The method involves application of Fourier series with Z-1 Summand an, bn and so on with n is equal to 2,3,..,Z (whereby Z is the number of cylinders of the engine) as a row representation of mean rotational speed values of the engine speed. The order n is so selected that an odd multiple of half camshaft frequency with in the row representation is taken into consideration, for generation of a control divergence en. Calculation of individual contribution for control divergence for each summand of the row representation by means of a predetermined value k is equal to k(n) and k(n) comes from a preliminary inspection. The method involves formation of complete divergence ez from the single contribution. An independent claim is included for the system.
