Spark plug with single side electrode An electric spark on the spark plug. A spark plug (sometimes, in British English, a sparking plug, [1] and, colloquially, a plug) is a device for delivering electric current from an ignition system to the combustion chamber of a spark-ignition engine to ignite the compressed fuel/air mixture by an electric spark, while containing combustion pressure within ...
Scientists have devised a way to replace spark plugs with laser beams to reduce fuel consumption and emissions. Also I have heard from a mechanic friend of mine that ford or someone has created an engine without spark plugs using insted a tessla coil like device. --Doom Child 04:13, 16 April 2006 (UTC)
Laser ignition is an alternative method for igniting mixtures of fuel and oxidiser. The phase of the mixture can be gaseous or liquid. The method is based on laser ignition devices that produce short but powerful flashes regardless of the pressure in the combustion chamber.
A wasted spark system is a type of ignition system used in some four-stroke cycle internal combustion engines. In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. The extra spark during the exhaust stroke has no effect and is thus ...
Doing so can help keep the spark plugs running optimally and make sure your car is getting the right amount of air flowing into the engine. Most replacement air filters cost between $20 and $75.
The spark plugs then use this burst of high-voltage electricity to ignite the air-fuel mixture. The ignition coil is constructed of two sets of coils wound around an iron core. Older engines often use a single ignition coil which has its output directed to each cylinder by a distributor , a design which is still used by various small engines ...
