Features spark plug failure

Come now to a very important issue that will be very useful in maintaining our car (at least if you have a gasoline-powered car, now let me tell you that diesel cars do not use spark plugs, and this is because in these engines the fuel is ignited when injected when the air is very hot due to its compression, so that the oil thus enters ignition)

 

Well, now it is clear that the engines do not use spark plugs diesels, will clearly also because gasoline cars do need them, since in these engines the fuel-air mixture is ignited with a spark, and the spark plug is responsible for genrarla by electric jump between two electrodes.

The spark plug is a highly durable piece, degree of thermal resistance should be very high since it comes into direct contact with the mixture to turn herself into the combustion chamber.

Nevertheless must maintain itself as cool as possible to avoid pre-ignition of the mixture (a pre-ignition on before that one time in the combustion chamber due to excess heat in it).

If we look at a spark plug having electrodes can see at one end which is to be inserted into the combustion chamber, along with a threaded portion, a body formed by an insulating material.

(Most ceramic case for its excellent properties) and ending at the other end the right way to connect the wires that feed electricity.
