Abstract

Device for detecting anomalous combustion phenomena in internal combustion engines, characterized by comprising at least one transducer capable of detecting the instantaneous conditions of fixing the cylinder head to the cylinder block caused by pressure variations in the combustion chamber and independent of the static load or slow variations due to other phenomena.
