What Does Engine Derate Mean? (and What Causes It?)

Derating is a process that reduces the maximum capacity of a system to match the load. In other words, it’s when you reduce the power output of your engine to match the load. It’s a way to protect your engine from overheating and damage.

Why Does Engine Derate Occur?

The main reason why an engine derates is because of excessive heat generated by the engine. It can occur for many reasons, but it usually happens when you run your vehicle at higher speeds for long periods of time. For example, if you’re driving across country and want to go as fast as possible without stopping or slowing down, your car will overheat due to friction between moving parts in the engine block.

How Does Engine Derate Work?

There are two types of derating: static and dynamic. Static derating occurs when a machine operates at its maximum capacity without derating while dynamic derating occurs when a machine operates at or near its maximum capacity but may be capable of running higher than its current operating level. If there is no change in load conditions during operation, then static derating will occur automatically (for example, when using a soldering iron).
