Articulating Actuators: Actuators Explained

From alternators last week to actuators today, PowerMark is home to a wealth of genuine branded Diesel generator parts and the knowledge you need to ensure the part is right for you. This week, we’ll discuss what an actuator is, why your Diesel generator needs one, and why you need one from our quality UK range here at PowerMark.

What is a Diesel Generator Actuator

In the simplest of terms, a Diesel generator actuator is often used to refer to the part that controls the Diesel intake of the engine. However, an actuator could be any part of your generator that controls another mechanism, so you must ensure proper research is conducted. Our team of experts here at PowerMark can help you ensure you pick the right part for your needs.

How an Actuator Works For your Diesel Generator

An actuator can be controlled in one of two ways. Typically, older models will be governed by a mechanical governor, but nowadays many are controlled by an ECU / ECM. They work alongside the rest of the electrical governing system of a generator, including the magnetic pickup sensor, to ensure your generator can run optimally under load.

An actuator governs the fuel injected into your generator, increasing it when load increases and vice versa.

A mechanical governor does this using gears and flyweights to detect changes in load and opens or closes the throttle accordingly. An ECU is a type of embedded system (aka computer) that uses input from a sensor to regulate the unit injectors, rather than a mechanical system.
