Low Speed Pre-Ignition

24/08/2018

LSPI is the phenomenon when the fuel air mixture ignites sooner than the engine designer intended - ignition occurs before the plug sparks. This pre-ignition causes an excessive pressure to build up inside the cylinder which, if mild, can simply cause abnormal engine noise, but if severe, will cause damage. The peak pressure observed during LSPI may be three times that encountered when the engine fires normally.
