Turbocharged engines seem to be much more popular in recent years, especially on smaller engines. How does a turbocharger “turbo”, and what is a supercharger?
In: 4
Turbochargers and Superchargers both exist to increase the pressure of the charge, i.e. the gulp of air a cylinder takes which fuel is combined with to burn. They’re both air compressors that compress the intake air to the engine.
The more air, the more fuel can be burned, the more powerful the resultant explosion, and the more power the engine makes.
The difference between the two his how this compressor is powered. With a supercharger it’s powered by a belt directly off the engine. With a turbocharger it’s powered from a turbine that sits in the exhaust gas flow.
