Easily replace glow plugs, spark plugs and injectors
The Injector and Glow Plug Dismantling Aid helps loosen stuck parts, while the Injector and Glow Plug Grease facilitates installation and future maintenance by protecting against corrosion and seizure.
What are glow plugs, spark plugs and injectors?
Glow plugs are used in diesel engines and have the task of reducing pollutants and engine noise during cold starts. As diesel engines do not have spark plugs like gasoline engines, the fuel-air mixture is ignited by the high compression in the cylinder, which leads to the mixture heating up. However, at cold temperatures, this compression is often not sufficient to ignite the mixture. This is where the glow plugs come into play.
Function: Glow plugs are heated electrically to temperatures of up to 1000 degrees. This additional heat preheats the combustion chamber, making it easier to start the engine.
Position: They are located in the cylinder head and protrude into the combustion chamber in order to heat the mixture there in a targeted manner.
Spark plugs, on the other hand, are used in gasoline engines and are responsible for igniting the fuel-air mixture in the cylinder by means of an electric spark. Without it, the mixture in the cylinder would not burn, as compression ignition does not work as it does in diesel engines.
Function: Spark plugs generate an ignition spark, which ignites the fuel-air mixture in the combustion chamber and thus starts combustion.
Position: Spark plugs are also mounted in the cylinder head and protrude into the combustion chamber. They are positioned so that they can ignite the mixture.
Injectors in diesel and gasoline engines are responsible for precise injection of the fuel into the cylinder. In both types of engine they inject the relavant fuel into the combustion chamber, where the fuel-air mixture is ignited by the spark plug.
Function: They ensure precise metering and atomization of the fuel. This increases the combustion efficiency and performance of the engine.
Position: They are also mounted in the cylinder head and inject the fuel directly into the combustion chamber.
