In internal-combustion engines with electric ignition, a plug, screwed into the cylinder head, connected with the induction coil or magneto circuit on the outside, and used to produce a spark to ignite the fuel-air mixture in the engine.
It is instrumental in converting high voltage energy into an arc that passes between its electrodes. This arc allows the gasoline-air mixture in the cylinder to ignite and expand, fetching power by pressing down the piston.
A device used on a petrol (gasoline) engine to produce the spark to ignite the fuel air mixture. The inner electrode is connected to a high voltage generator whilst the outer electrode is connected to the engine body to form a return path. The gap between the two electrodes is only small and the high voltage causes electricity to jump the gap and in so doing produces a spark. The high voltage source is only made available when a spark is required. and is triggered by the engine timing.
a device, inserted into the combustion chamber of an engine, containing a side electrode and insulated center electrode spaced to provide a gap for firing an electrical spark to ignite air-fuel mixtures
A device with two electrodes insulated from each other by a ceramic material, which screws into an engine combustion chamber. When the HT voltage is applied to the plug terminal, a spark jumps across the electrodes and ignites the fuel/air mixture.
The spark plug converts high voltage energy into an arc that passes between its electrodes. The arc causes the gasoline-air mixture in the cylinder to ignite and expand, providing power by pushing down the piston.
A little device sitting in the middle of the cylinder head, which generates an electric spark when the piston has reached the top point, and the air - fuel mixture is compressed. The spark will ignite the air - fuel mixture which will rapidly burn off. This in turn will drive the piston down again. Spark plugs are relatively cheap and should be checked often and replaced if necessary, typically every 4 to 5 races. A special spark plug tool is used to remove the plug. The temperature sensor is located around the base of the plug. The sensor to measure the RPM is attached to the spark plug cable. The spark plug cable is attached to the plug via the sending unit. The size of the gap at the bottom of the plug varies depending on the kind of spark plug and should be the gap specified by the engine manufacturer.
A device screwed into the combustion chamber of a spark ignition engine. The basic construction is a conductive core inside of a ceramic insulator, mounted in an outer conductive base. An electrical charge from the spark plug wire travels along the conduc
An ignition component threaded into the cylinder head that contains two electrodes extending into the cylinder that form a gap across which high-voltage electricity arcs to ignite the compressed air-fuel mixture.
A spark plug (also very rarely nowadays in British English, a sparking plug) is an electrical device that fits into the cylinder head of some internal combustion engines and ignites compressed aerosol gasoline by means of an electric spark. Spark plugs have an insulated center electrode which is connected by a heavily insulated wire to an ignition coil or magneto circuit on the outside, forming, with a grounded terminal on the base of the plug, a spark gap inside the cylinder. Early patents for spark plugs included those by Nikola Tesla (in for an ignition timing system, 1898), Richard Simms (GB 24859/1898, 1898) and Robert Bosch (GB 26907/1898).
