Knowing what you can use a spark plug for is important, since it helps one to understand the operating of their vehicle. This helps you to know how you can maintain your engine. By learning how a spark plug works as a component of the engine, you’ll learn how to keep your engine in peak condition, and at the same time lower emissions.
A spark plug, the electric device on the cylinder head of particular internal combustion engines delivers electric current to the combustion chamber. This electric current is transferred from the ignition system to a spark-ignition engine. This way, a spark plug delivers an electric spark in the engine’s combustion’s chamber, therefore, igniting the compressed air-fuel mixture. The spark delivered by the plug is transferred from a car battery through an ignition coil which acts as a transformer that transforms the insufficient 12-volt from a battery to around 20,0000 volts needed to create a spark.
The spark of electricity emitted by across a small gap in spark plugs creates an ignition for the required combustion, thus starting an engine. This electric spark puts the engine in motion, powering up your vehicle. Your vehicle can stay powered up and continue to have a smooth burning of the compressed air-fuel mixture. It is now obvious that your car cannot start or go anywhere for that matter without a spark plug. It is important, therefore, to keep your spark plugs healthy.
Some of the problems you might experience with bad spark plugs include poor engine performance, ignition problems, and low fuel economy. While spark plugs cannot create heat, they can remove heat from the combustion chamber. At the end of the plug’s firing end, the temperature must be kept low enough to prevent pre-ignition yet high enough to prevent fouling. By pulling from the combustion chamber unwanted thermal energy and transferring heat to the cooling system of an engine, a spark plug functions as a heat exchanger.
The ability to dissipate heat from the tip is considered as the heat range of a spark plug. Different spark plugs have different heat ranges. Consider this when looking for an ideal spark plug for your vehicle. There are other purposes of a spark plug. When spark plugs are not firing, in Saab Direct Ignition they are used to measure ionisation in the cylinders. This is achieved through the system putting a low voltage over spark plugs when they are not fired. The ionic current measurement is an alternative to the ordinary cam phase sensor, knock sensor as well as misfire measurement function.
So basically, a spark plug is used for ignition in engines so that internal combustion can occur, therefore, starting and powering a vehicle. It is useful to know how a spark plug operates since this will help you to understand when to replace a spark plug. Besides igniting automobile and other engines, spark plugs may also be used in other applications like furnaces where there is a need to ignite a fuel-air mixture. Sometimes during such an application, the spark plugs are known as flame ignitors.
