What are car spark plugs – Encyclopedia

The spark plug is one of the parts of the car that helps to start the engine by the combustion of fuel, because the purpose of the spark plug in the engine room is to generate the spark necessary to ignite the engine ; Although it is a small piece of metal, it has great value and importance inside the car, which is why drivers should know about it and when it should be replaced to avoid damage. damage resulting from its exposure to damage and how to examine it. We will get acquainted with the site of an encyclopedia about spark plugs, the damage that results from its damage and some methods by which spark plugs can be examined.

What are car spark plugs

• It is (spark plugs), as it is sometimes called spark plugs, and it is the connection between what is called the coil and the combustion chamber in the engine; In each of the cylinders there is often only one spark plug, and rarely two spark plugs per cylinder, due to the design of the cylinders.
• The spark plug is located inside the combustion chamber of the engine, and when air and fuel enter the combustion chamber, the spark plug emits a spark which ignites the fuel and generates gas. ‘energy.
• There are different types of buggies, including:

_ Types withstanding mechanical stresses.

_ Types withstanding shock and pressure stresses.

• It is also divided into other sections, and the choice is made depending on the type and design of the car. The manufacturer always determines the type of spark plug suitable for the car. A spark plug different from that specified by the company can be used, but it is not useful, and therefore you will have to change it constantly, and among these types:

Multi-Headed Spark Plugs: The purpose of this type is to increase combustion power by increasing the spark generated by the spark plug.

_ Single head spark plugs: There are two types available, the hot type, which is used in racing cars, and the cold type, which is used in the regular cars we use.

The problems to which Al-Bawaji is exposed

The spark plugs do not light and the engine does not start

When the spark plug cannot fire the spark that helps ignite the fuel, it causes the engine to run erratically, and the engine may stop running and then get back to work. Or the engine is running too fast even if the accelerator pedal is not depressed.

A different sound appears while the engine is running when the car is not moving

The engine running while the vehicle is stationary reaches a speed of 1000 rpm; And the work is in a calm and continuous voice; In the event of a fault, an unfamiliar, rough sound will appear when the engine is running.

Difficulty starting the car

Some may think the reason the car won’t start is because it needs fuel or the battery needs to be charged, but it could be the result of the spark plugs blowing out as it drains the battery.

Increased fuel consumption

If you notice an increase in the fuel consumption of the car, it may be due to damage to the spark plugs, and we find that the increase is more than 30%.

Difficulty accelerating the vehicle

The car’s ability to increase speed decreases due to the car’s inability to respond to pedal pressure or being delayed in responding to it than usual.

Spark plug check

Checking spark plug wires

This is done using one of several different manual lighting methods for easy examination looking for any faults in the spark plug wire and looking for any bends or cuts.

Examine the insulators surrounding the spark plug wire for damage from engine overheating and ensure there is no corrosion in the area between the base, spark plug and engine .

Engine start

Start the car engine, check for spark plug damage, check for arcing, and listen for unusual sounds that indicate an electrical leak.

Spark plug wire resistance test

The resistance index of the spark plugs is recognized by the vehicle manual attached to it; In order to determine the resistance of the wire, is it the right or the wrong resistance, this is done by using an ohmmeter and placing the gauge probes at the end of the wire and making sure they are correct, taking into account that the probes do not come into contact with any other metallic object.
