The paper aims at providing a concise revision of current knowledge of engine knock phenomenon based on previously published works. Theories behind the origin of knock are discussed. Differences between knocking combustion in spark-ignition and hard work of compression-ignition engines are explained. An overview of direct and indirect methods of knock occurrence detection is given. The most commonly used indices for the evaluation of knock intensity are presented.

Artykuł ma na celu zwięzłe podsumowanie obecnego stanu wiedzy w zakresie zjawiska spalania stukowego na podstawie dotychczas opublikowanych prac. Omówiono teorie dotyczące powstawania spalania stukowego. Nakreślono różnice między spalaniem stukowym w silnikach o zapłonie iskrowym i twardą pracą silników o zapłonie samoczynnym. Scharakteryzowano bezpośrednie i pośrednie metody wykrywania spalania stukowego, a także przedstawiono najczęściej stosowane wskaźniki do oceny intensywności spalania stukowego.
