Kit 4 Glow Plugs Adaptable Renault Scenic II 1.900 Diesel 81/85/88/92/96kw from 2003>

• Preheating : When the engine is started, the glow plugs heat up rapidly to increase the temperature of the air in the combustion chamber, making it easier to ignite the diesel fuel.
• Ignition : In a diesel engine, the fuel ignites by compression; however, in cold conditions, the glow plug helps ensure that the diesel fuel ignites properly.

• Materials : Glow plugs are generally made of heat and corrosion resistant materials, such as steel or ceramic.
• Design : They can come in a variety of shapes and sizes, but typically look like small coils or tubes that fit into the cylinder head.

• Standard Voltage Glow Plugs : They heat up to a set temperature and maintain that heat for a certain period of time.
• High Voltage Glow Plugs : They heat up faster and reach higher temperatures, reducing engine start times.

Glow plugs can wear out over time and lose efficiency, so it is advisable to check them regularly and replace them if necessary, especially if you notice difficulty starting the engine.

In summary, the diesel glow plug is a key element for the correct functioning of diesel engines, contributing to the efficiency and reliability of the vehicle, especially in adverse weather conditions.
