In this video, I explained the difference between supercharges and turbochargers.
What is a Turbocharger?
A turbocharger consists of a compressor wheel and exhaust gas turbine wheel coupled together by a solid shaft and that is used to boost the intake air pressure of an internal combustion engine. The exhaust gas turbine extracts energy from the exhaust gas and uses it to drive the compressor and overcome friction.
Basically, a turbocharger is connected to an engine to give it more power. This allows smaller engines to put out more horsepower and torque than they ordinarily would. Turbochargers utilize the engine's hot, expelled air to spin the compressor wheel and take in outside air. This reduces the amount of waste produces.
What is a Supercharger?
A supercharger is an air compressor that increases the pressure of air supplied to an internal combustion engine. This aids in higher power output as the engine gets more oxygen in each of its intake cycles and helps it to burn more fuel. Superchargers can be powered mechanically by means of a belt, shaft, or chain connected to the engine’s crankshaft.
Here is some advantages and disadvantages of superchargers.
Advantages :
Higher power output.
Greater induction of charge mass.
Better atomization of fuel.
Better mixing of fuel and air.
Better torque characteristics over whole range.
Quick acceleration of vehicle.
Complete and smooth combustion.
Disadvantages :
Increased detonation tendency in SI engines.
Increased thermal stress.
Increased heat loss due to increased turbulence.
Increased gas loading.
Increased cooling requirements of the engine.
Here is some advantages and disadvantages of turbochargers.
Advantages :
Significant increase in horsepower.
Power vs size: allows for smaller engine displacements to produce much more power relative to their size.
Better fuel economy: smaller engines use less fuel to idle, and have less rotational and reciprocating mass, which improves fuel economy.
Higher efficiency: turbochargers run off energy that is typically lost in naturally-aspirated and supercharged engines (exhaust gases), thus the recovery of this energy improves the overall efficiency of the engine.
Disadvantages :
Turbo lag: turbochargers, especially large turbochargers, take time to spool up and provide useful boost.
Boost threshold: for traditional turbochargers, they are often sized for a certain RPM range where the exhaust gas flow is adequate to provide additional boost for the engine. They typically do not operate across as wide an RPM range as superchargers.
Power surge: in some turbocharger applications, especially with larger turbos, reaching the boost threshold can provide an almost instantaneous surge in power, which could compromise tyre traction or cause some instability of the car.
Oil requirement: turbochargers get very hot and often tap into the engine’s oil supply. This calls for additional plumbing, and is more demanding on the engine oil. Superchargers typically do not require engine oil lubrication.
