Still, if youre not What Spark Plugs Fit My Car? The laser-guided arc technology could be useful in applications to deliver a spark of electricity to a precise spot.[15][16]. /SMask /None>> (Knock is sometimes referred to as spark knock.)Retarding the ignition timing will reduce knock. Triggered spark gaps are made in permanently sealed versions with limited voltage range and in user-pressurized versions with voltage range proportional to the available pressure range. 6) WebCD ignitions have very fast Voltage rise (short rise time) and therefore they also work very well with spark plugs that have high capacitance, such a spark plugs with multiple gaps and/or surface discharge spark plugs. The usual way that a spark plug is fired is to provide a low-voltage DC pulse to an ignition coil. Most commonly, this is a third electrode, as in a trigatron. This property is the reason uncontrolled electrical arcs in apparatus become so destructive since once initiated, an arc will draw more and more current from a fixed-voltage supply until the apparatus is destroyed. Low octane fuel has a low resistance to knock (low resistance to ignition). As the air temperature or humidity decreases, the air density increases, requiring a richer air-fuel mixture. Privacy and Security Statement endobj The first continuous arc was discovered independently in 1802 and described in 1803[7] as a "special fluid with electrical properties", by Vasily V.
