Compressors: Basics, Types, Working Principles, Applications, Design (online calculator)

April 29, 2023

What is a compressor? As we know liquids are incompressible (theoretically) whereas gases or air can be compressed to a desired pressure (above atmospheric pressure). Practically, Gases can not be used for engineering purposes (such as in industrial pneumatic systems, blowers, household gas supply for heating, hospital oxygen supply systems, air-conditioning, etc.) at atmospheric pressure.

Auxiliary Belt Drive System (ABDS) in IC Engines/ Belt Starter Generator Micro Hybrid

February 20, 2023

The Auxiliary Belt drive system (ABDS) should not be confused with the Timing Belt drive system (Synchronous Belt Drive System -SBDS) of the internal combustion engine. Timing Belt drive takes power from the crankshaft and drives the camshaft/s that in turn drives the inlet and outlet valves of the engine. On the other hand, an
