Turbocharger and its working


The Working Principles of a Turbocharger

In an internal combustion engine where there is a need to increase the power, a turbocharger comes in application. In order to accomplish this, the turbocharger increases the mass flow rate of air entering the engine by the turbine action driven by it’s exhaust. It is widely applied in aircrafts, automobiles and motorcycles.



Turbocharger design and function


The turbocharger is like a miniature gas turbine, it is a small radial fan driven by the forward motion of the engine exhaust. Comprising the turbocharger are the turbine and the compressor sharing a single shaft. When the exhaust gasses enter, the fan rotates which drives a compressor. Air is then squeezed by the compressor before being delivered to the engine air intake manifold. Because air is compressed, the engine could then take in greater amounts of air to the cylinders. Usually the engine takes in air through a vacuum created by the downward stroke of the cylinder. The normal air pressure is at 14.7 psi and there is a limit to the pressure difference across the intake valves resulting in a limited air mass flow rate. In order to increase the intake, pressure must then be increased. In this way additional oxygen to the engine makes it possible to burn more fuel which increases the power of the engine. Increase air pressure is possible with the turbocharger application.



Turbochargers, although applies the same as superchargers except for small variations. Superchargers, particularly Centrifugal superchargers were spun by the rotation of the engine’s crankshaft. This made turbochargers more efficient in terms of recycling energy loss through the exhaust.



Although the turbocharger consists of a turbine and a compressor, several working components actually comprise it. The turbine and the impeller are contained in their own housing. The housings fitted around the compressor impeller and turbine directs the flow of gasses through the wheels. The motion of the gasses causes the impeller to spin. In this case the size of the impeller wheel dictates the amount of gas it could take. The single shaft connecting the turbine to the compressor is housed in the center hub rotating assembly (CHRA). The CHRA also contains bearing to minimized friction, lubrication and in some cases the turbocharger cooling system; water cooled models have entry and exit points for the engine coolants to cycle. Devices such as waste gates then control the spin of the turbine.

Front Mount Intercooler





You probably have seen cars driving around with this sort of arrangement under the front grill.This is called a Front mount Intercooler to cool down the turbo of the petrol engine.

hahah yeah go for it
okay tell me Supercharger is more beneficial or Turbocharger ?

Supercharged Car - like Kompressor C180/200 Mercedes

Turbo charged car - Like Nissan 240SX turbo

Supercharger and turbochargers are way too different'
Most of the people think they both do the same thing but nope.
turbo charger uses expelled gasses from the engine to run the turbine and then compressor and its instant as in the sense when you push your accelrator harder the turbo starts kicking in and you can feel it and it turns off when you take the foot off the pedals and drive it on ideal conditions.
But Supercharger is powered by the engine as its setup on the top of the head of the engine or can be at some other place where it can be driven by the engine belts. Its always working at the expense of our own fuel. It continously sends the compressed air to the engine,increasing the power output at all the time. It doesn't effect much if you press the accelarator harder.
Setup is easier than a turbocharger no doubt.
Turbo charger needs a separate intake manifold, a blow off valve , a pod filter, a Intercooler , a turbo timer, waste gate setup and above of all need a engine that can bear its power.

Apparently there are some cars that are both
Golf was to make one but they did make justa  engine which was a turbo charged and supercharged at the same time
