How does a speed limiting device work? This article is focused on how a speed limiting device works and also, it will answer the bulk of your questions as regards the device.
Sometimes referred to as the speed governor, a Speed Limiting Device is an electronic device installed in a vehicle, with the sole purpose of ensuring the vehicle maintains a speed limit according to the regulations of Nigeria.
Today, let's find out the functions of these speed limiters with Naijacarnews!
1. How does speed limiting device work?
Basically, the device is for safety. It does not give the driver enough room to accelerate beyond the specified speed limit, as stated by law, and as programmed in the vehicle as well. So, no matter how often the driver uses his accelerator, the pre-set speed limit will not be exceeded.
When installed, a series of sensors detect how fast you're going, then communicate that information to the engine's computer, which manages nearly all the engine's functions. Once you reach a pre-determined top speed, the computer steps in and restricts the flow of air and fuel to the engine and even the sparks that cause combustion.
Either way, you'll be unable to exceed the top speed as determined by the car's manufacturer.
