Advisory system for engine knock detection
Author: Kubíček Miroslav
This thesis is focused on the phenomenon
of knocking in spark-ignition
engines. Knocking is caused by the "bad"
burning of the air-fuel mixture in the combustion
chamber of the engine. It can lead
to its destruction. Oscillation of a piston
caused by knocking appears on relatively
constant frequency because it is mainly
due to its mechanical dimensions. The
object of this thesis is to detect the knocking
and its frequency using accelerometers
mounted near the combustion chamber.
The main part of this thesis is the library
of the advisory system with the program
that calls it. This allows it to display
the frequency characteristics required to
detect knocking and its frequency.
