Spark Plug - CCH404 CHAMPION

The spark plug is the most important element of the ignition system for internal combustion engines (ICE) with forced ignition of the working mixture. This device is designed to ignite the working mixture in the engine cylinder in order to obtain thermal energy, which is subsequently converted into mechanical work by means of the crank mechanism.

The principle of the spark plugs work

CHAMPION brand Spark Plug are the most widely used in modern automotive internal combustion engines. Ignition of the working mixture in such devices is carried out by an electric arc discharge in the form of a spark between the electrodes of a candle, which occurs when a powerful electric pulse with a voltage of several thousand or even tens of thousands of volts is applied to the electrodes. A thin layer of air in the spark gap cannot withstand the colossal voltage between the electrodes, and a kind of mini-lightning breaks through it, setting fire to the mixture.

The impulse is applied to the electrodes of the plug at a strictly defined point in time - when it is necessary to ignite the prepared working mixture in the cylinder.
