Can someone please tell me step by step how a turbo charger works? Thank You?

Answer 1

Turbochargers are a type of forced induction system. They compress the air flowing into the engine (see How Car Engines Work for a description of airflow in a normal engine). The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the charging. This can significantly improve the power-to-weight ratio for the engine.

In order to achieve this boost, the turbocharger uses the exhaust flow from the engine to spin a turbine, which in turn spins an air pump. The turbine in the turbocharger spins at speeds of up to 150,000 rotations per minute (rpm) -- that's about 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the temperatures in the turbine are also very high.

One of the surest ways to get more power out of an engine is to increase the amount of air and fuel that it can burn. One way to do this is to add cylinders or make the current cylinders bigger. Sometimes these changes may not be feasible -- a turbo can be a simpler, more compact way to add power, especially for an aftermarket accessory. Turbochargers allow an engine to burn more fuel and air by packing more into the existing cylinders. The typical boost provided by a turbocharger is 6 to 8 pounds per square inch (psi). Since normal atmospheric pressure is 14.7 psi at sea level, you can see that you are getting about 50 percent more air into the engine. Therefore, you would expect to get 50 percent more power. It's not perfectly efficient, so you might get a 30- to 40-percent improvement instead.

Answer 2

Very simple:

It is a basic a high volume compressor that is powered by the forced and expanding exhaust gasses for better control and flexibility than a supercharger (belt/gear driven). Exhaust gases spin a common shaft like a side-ways pin-wheel. The low pressure tail-way is the center opening away from the common shaft. The common shaft spins a radial compressor. Air enters and is spun with the blades. Centripetal force moves the air to the outside of the disk where the space is gradually confined (compressing the air). This forced air is then directed into the engine in pretty conventional fashion.

A wasted gate regulates the exhaust (and bleeds off excess) making this more manageable and a Pop-off valve ensure a maximum amount of pressure isn’t exceeded in the intake system.

Answer 3

ok, as the exhaust exits your engine, it enters the header. with a turbo, before it goes into the exhaust pipe it passes through a turbine which is connected to another turbine on the intake side. this one draws in the outside air and compresses it before it inters the cylinder and the process repeats. more air + more fuel = more power.
