Glow Plug Controller

A Glow Plug Controller is a component of the Engine Electrical System in non-aircraft engines. It is classified under the supply class Engine Electrical System Components, Nonaircraft, which falls under the supply group Engine Accessories.

The Glow Plug Controller is responsible for controlling the operation of the glow plugs in a diesel engine. Glow plugs are used to preheat the combustion chamber in cold weather conditions, ensuring reliable starting and smooth engine operation. The controller regulates the current flow to the glow plugs, allowing them to reach the optimal temperature for ignition.

The Glow Plug Controller typically consists of a control module, relays, and wiring harnesses. It receives signals from the engine control unit (ECU) or a temperature sensor to determine when to activate the glow plugs. Once activated, the controller supplies power to the glow plugs for a specific duration, based on the engine's requirements and ambient temperature.

By controlling the operation of the glow plugs, the Glow Plug Controller helps improve cold-start performance, reduce emissions, and enhance fuel efficiency in diesel engines.
