Final answer:
Turbochargers and superchargers improve power in engines by increasing the amount of air supplied to the combustion chamber, resulting in more fuel being burned and a higher output of energy.
Step-by-step explanation:
Turbochargers and superchargers improve power in engines by increasing the amount of air that is supplied to the combustion chamber. This, in turn, allows for more fuel to be burned, resulting in a higher output of energy. Turbochargers work by utilizing the exhaust gases from the engine to spin a turbine, which then compresses the incoming air. On the other hand, superchargers are driven directly by the engine's crankshaft, which forces compressed air into the engine.
For example, let's consider a turbocharged engine. As the exhaust gases pass through the turbine, they spin the turbine wheel, which is connected to a compressor wheel. The compressor wheel then draws in and compresses fresh air from the outside, which is delivered to the engine's intake manifold at a higher pressure. The increased air pressure allows for a greater amount of fuel to be added, resulting in more power being produced during combustion.
