Com funcionen les bugies

Under the action of high voltage, the air between the central electrode and the side electrode of the spark plug will rapidly ionize, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain value, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulation, and the gap forms a discharge channel, Fent que el fenomen "desglossament" es produeixi . en aquest moment, el gas forma un cos emissor de llum, és a dir, "Spark" {{3} El cilindre .
