The term turbo chargers is very common in advertisements of Diesel Engines specially SUVs, you must have seen they specially write in advertisement ‘Turbo Charged’ or “Turbo” on the vehicle body
You must have wondered what this turbo is.
Turbo Charger is an Exhaust Gas Turbine, a class of Supercharger, which is run by exhaust gases of a Diesel engine
Turbo Charger is Generally Used in Medium to Large Diesel Engines, from SUVs to Diesel Locomotives
The Exhaust Gases of Diesel Engines have lot of energy i.e. they can drive a Turbo Charger.
So what this Turbo Charger does?
Diesel Engines intakes only Air which is compressed to high temperature and pressure and then fuel (diesel) is spared in the Cylinders which burn due to high temperature of air and then explodes to release mechanical power
Now if by some means we can compress the intake air and raise its temperature slightly, we can increase the efficiency of the engine thus we will get better average (fuel efficiency) of our vehicles
The Turbo Super Charger uses exhaust gases of engine to compress the intake air and then it is send inside the cylinders, thus utilizing the exhaust energy and simultaneously increasing the engine efficiency
But Turbo Chargers are not effective in small diesel engines like of small diesel cars but are mandatory for large engines like of SUVs
