How does a Glow Plug

Control Unit work?

Today’s diesel engines are highly technical, operating at very high standards in order to meet performance expectations and environmental regulations. That means that all components need to be in top condition. Running the engine with worn or broken ignition parts causes lower performance, higher emissions, premature wear or even severe (and expensive) damage.

Quality BERU®️ Glow Plugs and Glow Plug Control Units, engineered and built to OE-standards, are recommended to ensure a smooth installation, long-lifespan and reduced exhaust emissions.

What is a BERU®️ Glow Plug Control Unit?

BERU’s innovative Glow Plug Control Units add even more intelligence to the modern diesel engine. The Glow Plug Control Unit plays a vital role in optimising the function of the glow plug to extract optimum performance from the engine, so it runs cleanly and smoothly during the start-up phase, even on the coldest mornings.

How does a BERU®️ Glow Plug Control Unit work?

The BERU®️ Glow Plug Control Unit is placed between the Engine Control Unit (ECU) and the Glow Plugs. It requests vital information from the ECU, including glow requests, engine speed, coolant temperature and the amount of injected fuel to an exact desired glow plug voltage. The Glow Plug Control Unit then uses this information to adjust the current on-board voltage to this value, optimising engine operation.

And, if an engine doesn’t operate as it should, the BERU®️ Glow Plug Control Unit offers additional diagnostical data.

In newer applications, the BERU®️ Glow Plug Control Unit enables constant communication with the ECU, while in older applications, it works mostly as a switcher for the glow plug.

Types of BERU®️ Glow Plug Control Units

There are three main types of BERU®️ Glow Plug Control Units:

  • Glow Plug Control Relay
  • Glow Plug Control Unit ASIC-based
  • Glow Plug Control Unit Micro-controller

Take a look at our connected blog post for more information on these variations.
