Turbocharger
A turbocharger is basically a centrifugal compressor driven by a turbine that is driven by the exhaust gases or emission gases that leave the engine of your car. The compressor used in the construction compresses the air that is about to enter the engine, at high pressure. With increasing pressure, the weight or amount of fuel entering the same space inside the engine increases. In this way, fuel combustion is more efficient within the engine chamber and ultimately results in increased vehicle performance from the same engine displacement without the need for a larger displacement engine. For example, if you put 30% more fuel into the same engine cylinder, burning that fuel will produce about 30% more energy of the same engine size.
Supercharger
A supercharger is very similar to a turbocharger with a compressor used to force high pressure air into the engine. The main difference is that in the case of the supercharger, the engine itself runs on the turbocharger, while in the turbocharger, the exhaust energy from the exhaust gas or the emission, which otherwise goes to waste, is used to run The compressor. With more compressed air, more oxygen and fuel comes into the combustion chamber, therefore, more power is developed.
In general, a supercharger and a turbocharger are of the same type of provisions but have a set of characteristics that distinguish the two.
Difference between the supercharger and the turbocharger
• First, the driving power of the two units is considered. The compressors of the superchargers are driven by the power taken directly from the engine, whereas, as mentioned above for the driving of a turbocharger unit, the exhaust gases are used. Since the compressor directly extracts the mechanical energy from the engine, it is less efficient compared to a turbocharger that uses the energy of the waste gas.
• With this advantage of turbochargers over superchargers, the former are used where fuel economy is a concern, ie in many of today's cars, while superchargers are used in sports cars that are designed for faster speeds Fast and not better economy.
• Secondly a supercharger is easier to control in terms of output power, while turbochargers are known for their dramatic increase in tremendously high working pressures and temperatures making it intrinsically harder to control at the time when Deliver additional power.
• Another important difference between the two is that as the compressor is driven directly by the engine through belts, the response is quite instantaneous and a sudden increase in power is observed. On the other hand, in the turbochargers, the exhaust gases control the drive and, therefore, the system takes a little before it reaches the operating speed after opening the throttle, which is also known as Turbo Lag.
• Complexity in design is another factor and at this point the turbocharger takes the lead with its compactness and requires much less space. In contrast, a supercharger is more difficult to adopt in a car and the modification is too slow as more space is needed for it.
• Expensiveness of the two is quite different with the superchargers being more expensive than a conventional turbocharger. Now one day the whole vehicle that has either supercharger or turbocharger, will be intercooled. Since the temperature of the compressed inlet air is high, an intercooler is used to cool this air to make it more efficient in terms of combustion.
