Signal-based diagnostics of the gasoline injection engine

Abstract

The paper addresses one of the methods of diagnosing the gasoline injection engine available on the vehicle, namely signal-based diagnostics. The most used algorithms for signal-based diagnostics are highlighted. The possibilities offered on an experimental basis are presented and the tests performed in this respect are presented. Time-frequency analysis techniques are applied to detect defects caused in the case of the Audi A6 car engine.
