ABSTRACT
The Exhaust Gas Recirculation is a popular system of recirculation of the automotive vehicle emission. The principle of working depends on the forcing in the part of outlet gas to the combustion chamber. The polluted flowing valve of circuit has an influence on stability of engine’s work. The authors presents a new way of diagnosis in automotive vehicle which depend on detection and measure of vibroacustic vibrations that were subjected to digital signal processing. It seems that EGR circuit that does not work properly shouldn’t have an influence on vibrations generated by an engine. However, authors indicate that this statement is wrong.
