Heater plugs, often referred to as intake air heaters or grid heaters, are components found in some diesel engines to aid in starting and improve performance, particularly in cold weather conditions. Unlike glow plugs, which heat the air inside the combustion chamber, heater plugs warm the air entering the engine. Here’s an overview of their function, benefits, and maintenance:

Overview of Heater Plugs

Function

Preheating Intake Air: Heater plugs warm the air in the intake manifold before it enters the combustion chamber.

Facilitating Cold Starts: They help ensure that the air-fuel mixture reaches a temperature conducive to efficient combustion, making it easier to start the engine in cold weather.

Reducing Emissions: By aiding in better combustion from the start, heater plugs help reduce the emissions of unburned hydrocarbons and white smoke.
