Turbo Charger and Super Charger

Difference between a Turbo Charger and a Super Charger 

A Turbo Charger and a Super Charger is a device which is used to increase the output power of the engine by compressing more Air/Fuel Mixture in the cylinder .Both have the similar purpose to pressurize air in the intake manifold the difference lies in the shape and the way it compress the air in the manifold

Left:Turbo Charger

Right: Super Charger

Turbo Charger:-

                                           It uses the energy from the burned gases coming out of the cylinder,This way it is more economical then its counterpart . A Turbo provide more Power at high RPMs then at Low RPMs , But because it dose not waste useful energy it is more popular then the Super Charger

How It Works:-

                            Its Working as a electric turbine used in Dams. When the Exhaust gases from the engine come out of the cylinder by the push of the pistons exhaust stroke it creates pressure in them which moves the turbine wheel too which another turbine wheel is fitted via a shaft which is called compressor wheel . As shown on the right . The Exhaust gases(Red Lines) coming from the engine rotates the turbine wheel to which the compressor wheel is attached which creates vacuum thus sucking air from the air outside and pumping it in the intake manifold (Blue Lines).

Care and Maintenance:-

                                          Since is has more components then the Super Charger it requirement more Care and Maintenance . The Turbo Charger becomes very hot because of  the exhaust thus it requires oil from the engine to cool the shaft transferring the centrifugal force . If the oil is not supplied to the shaft it will jam the bearings in the Turbo thus damaging the Turbo . And a Boost pressure Regulator simply known as a Blow-off Valve is used to control the pressurized air in the manifold that it dose not become too much for the intake to hold . If the Pressure is too much the Turbo will start making a Shuttering sound which causes damage to the Engine's and the Turbo's Life.

Problems and Causes:-

1. The main problem with a turbo is that it becomes jammed in many cars due to carelessness when you use a turbo and are about to shut off the engine do it after waiting at idle for about 3-5 minutes too let the Turbo cool down if u don't the hot oil in the turbo will stop moving due to which the hot oil will cause bearing ware thus jamming the turbo fans
2. Turbo Shuttering is caused because of the blow-off valve not set properly, Setting it properly will solve that problem the setting of the blow-off valve depends on the size of the Turbo
3. Some Turbo Chargers use Intercoolers , If the intercooler is choked because of dust of other contamination's the vehicle will start missing or start back firing . So it is advise to keep the intercooler clean. 

 Super Charger:-

                                            The Super Charger uses the Power of the crankshaft to work , Thus it wastes the power of the engine but provide better response then at low RPMs .Because it is working if the engine is working.The Turbo doesn't work till meduim RPMs like 5000 RPMs.Where as the Super Charger Even Works at Idle speed (800 RPMs) 

 How It Works:-

                             It has Fins or Propellers shaped like Loops or Screws as Shown on the Right . The Fan Belt Rotates the main gear connected to both Fins which rotates the Fins which pushes the air inside the intake manifold . It has simpler mechanics then the Turbo.

That means More the Engine RPMs more the air is being compressed in the intake manifold.

Care and Maintenance:-

                                          Since it does not have that much components it is nearly maintenance free . The only maintenance it requires is that no dust or other solid particles does not reach the Super Charger through the Air Filter , Because it will cause its bearings to get stuck thus jamming the loops or fins

                                                                                                   

 Problems and Causes:-

                                        There is only one problem which occurs in Super Chargers if Fitted to a small engine it will start to cause back fire and miss fires in the cylinder which can be dangerous to the driver and can cause accidents (small Engine as in lower then 1.5 liters )

If there is a mistake in any topic because of my low knowledge point it out for me so i can study it again ! Thank You
