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
A turbocharger is a fan powered by engine exhaust that compresses extra air into an engine intake. A super charger is not powered by exhaust, but by the engine itself or even electrically powered. Turbochargers have an inherent lag while superchargers are a bit faster. Turbochargers are more fuel efficient, while superchargers are faster with generally higher performance.
