Pre-ignition for an automobile engine to continue on for thousands of kilometers with mild detonation, pre-ignition can destroy an engine in just a few strokes of the piston. Pre-ignition Pre-ignition (or preignition) in a spark-ignition engine is a technically different phenomenon from engine knocking, and describes the event wherein the air/fuel mixture in the cylinder ignites before the spark plug fires. Pre-ignition is initiated by an ignition source other than the spark, such as hot spots in the combustion chamber, a spark plug that runs too hot for the application, or carbonaceous deposits in the combustion chamber heated to incandescence by
Piezo ignition connection is required, though wires are sometimes used to locate the sparking location away from the crystal itself. Piezo ignition systems can be operated by either a lever, push-button or built into the control knob. An electric spark is usually generated once per turn of the knob or press of the button. Piezo ignition Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters, and potato cannons. Piezo ignition uses the principle of piezoelectricity, which, in short, is the electric charge that accumulates in some materials in response to high pressure.
