Electrodes

So at a time and working several sides of the electrodes, extending the life of rock candles. Combustion of the working mixture candles with multiple side electrodes is deteriorating due to the fact that her access to the most critical part of the chamber – the spark is difficult. Among other things, the more electrodes, the more intense the heat away from candles. For these structures over the possibility of formation of carbon and bad properties of the engine for CO and NO. As a result, designers and vividly explore another path – a candle with one lateral electrode minimum or … does not ground electrode. The last system in real life you can meet only on the sports car.

They perform the role of the whole ground electrode side edge and a sparkle in fact formed in the form of bundles of three or four bridges. Make candles with no lateral electrodes in the race cars have for use of heavy-duty charge. This charge, first, eats too soon electrodes of any material, and secondly, has probability 'jump' from the side ring in center. Another method of 'escape' from the use of ground electrode at the time suggested the company SAAB. In that system, its role fulfilled … piston. The idea was ingenious and easy. Ignition mixture of all the gasoline engine takes place when the piston moves upward when it compresses already previously received by the camera working mixture. On the surface of the piston was placed needle-shaped protrusion, with whom and went spark, getting after it on the center electrode plugs, located in the usual place for it.
