Understanding the Governor in Briggs and Stratton Lawn Mowers

To understand the governor in Briggs and Stratton lawn mowers for tuning, you need to know what it is and how it works. That’s why we’ve included two sub-sections: what a governor is and the mechanics of a governor in lawn mowers.

What is a Governor?

Governor is a device that maintains a machine’s desired velocity under varying loads. It adjusts the engine’s throttle to make sure it works safely and efficiently. This helps extend engine life, as it prevents it from running too fast.

Small engines, like in lawn mowers, don’t have mechanical governors. Instead, they use electronic sensors and microprocessors. Governors have been used for centuries – like James Watt’s steam engine governor from 1788. It was mainly used to regulate machinery speed in textile mills and other factories.

So, understanding the governor is important for keeping your Briggs and Stratton lawn mower in good shape. Proper care and maintenance of this device will ensure your lawn looks great all season!

How does a Governor work in Lawn Mowers?

The governor in Briggs and Stratton lawn mowers is a must-have part of the engine system. It adjusts the throttle to maintain optimal speed when the load increases.

What sets Briggs and Stratton apart is their special mechanical governor. This is less likely to fail and needs less maintenance than the electronic governors used in most machines.

The governor also acts as a safety feature by avoiding overspeeding which can damage the engine or even harm the operator. Newer models come with advanced governors that optimise fuel efficiency.

Governors were first used in steam engines during the Industrial Revolution to control power. Later they were adapted for other machinery, like lawn mowers. It’s hard to believe we used to operate an engine without them! Adjusting the governor on your mower is like giving it a performance-enhancing boost – without the risk of getting caught!
