Considering this, is a supercharger and blower the same thing?
We'll use the terms supercharger and blowerinterchangeably. The centrifugal supercharger is verysimilar to a turbocharger, except the centrifugalsupercharger is driven by a belt off the engine, while theturbocharger is driven by the force of the exhaustgases.
Likewise, what are the 3 types of superchargers? There are three main categories of superchargers forautomotive use:
- Centrifugal turbochargers – driven from exhaustgases.
- Centrifugal superchargers – driven directly by the enginevia a belt-drive.
- Positive displacement pumps – such as the Roots,twin-screw (Lysholm), and TVS (Eaton) blowers.
In this manner, how does a blower supercharger work?
A Roots-type blower pulls in air and compressesit in the engine's cylinders. The speed at which thesupercharger fills the cylinders depends on how quickly itis driven by a pulley and drive belt. The main drawback toRoots-style superchargers is the consistency of the aircharge.
Does a supercharger use more fuel?
The main reason for the increase in fuel economyis an increase in volumetric efficiency. A normally aspiratedengine cannot run at more than 100% volumetric efficiency,but a supercharged engine can, because it can pump more airthan the displacement of the engine would normallypermit.
