Isimo se-surface ye-diesel engine knock siyefana nesenjini kaphethiloli, kodwa imbangela yokungqongqoza ihlukile.
Nakuba kokubili ukuqhunyiswa kwabangelwa ukushiswa kukaphethiloli okuzenzakalelayo, imbangela yokuqhunyiswa kwenjini kadizili imane nje iphambene nenjini kaphethiloli, ngoba udizili akulula ukusha okuzenzakalelayo, ukuqala kokuvutha okuzenzakalelayo, ukunqwabelana kukaphethiloli kusilinda okubangelwa kakhulu.
