Reflection Essay

When people talk about race cars or high-performance sports cars, the topic of turbochargers usually comes up. Turbochargers also appear on large diesel engines. A turbo can significantly boost an engine's horsepower without significantly increasing its weight, which is the huge benefit that makes turbochargers so popular. A turbo basically makes your car go faster by forcing compressed air into the engine. It’s a type of force induction system; it forces more air into the cylinder which means more fuel can be added in which results as more power is produced. It increases the power to weight ratio, and which is good because the turbo charger in addition does not weigh very much.

What it needs to do to achieve this boost is the turbocharger uses the exhaust flow from the engine to spin a turbine; which spins an air pump. The turbo charger spins at about 150,000 rpm on average. That is around 30x faster than a normal car engine. A big factor for the exhaust section of the turbocharger is the westgate. The westgate is a device with the intentions of controlling the boost pressure of the turbocharger, it is rarely found in diesel engines. But there are different types of westagates, internal and external. They both are a means of air flow from the exhaust to the Turbines. Bypassing the exhaust reduces the power driving the turbine wheel to match the power required for a given boost level.

And that concludes my explanation for turbochargers
Now onto my explanation of how superchargers work. Super chargers basically do what a turbocharger does, except they still are different and have different properties to them. A supercharger puts more oxygen into the cylinder per cycle to put more support for the combustion stroke of the engine. And that makes it so more fuel can be burned at once and more of the stroke to be done at once power for the supercharger can be provided mechanically by a belt, gear, shaft or chain connected to the engine’s...
