TURBO CHARGER

TURBO CHARGER

                  Turbocharged engines are very popular today because of their Jekyll and Hyde personality. Since the turbocharger generates extra power, it allows smaller turbocharged engines to equal larger nonturbocharged ones in acceleration. But because the turbocharged engines are smaller, they're also generally capable of better fuel economy. It's like having two engines in one: a small, economical engine for ordinary driving and a responsive, high-performance engine for passing and such.But turbocharged engines are only more fuel efficient when you drive with a light foot. Once you get the turbocharger all worked up, even a small turbocharged engine can suck down gas just like those larger engines. So if you drive aggressively, you may want to consider a larger nonturbocharged engine, as you're not likely to see huge fuel economy gains with that driving style.

                   

                     You also should consider that the turbocharger is another moving part that can fail. In fact, it often does fail during the life of the car. Not surprisingly, replacement turbochargers don't tend to be cheap.

Pros: A turbocharged engine is typically more fuel efficient than a regular engine at a given horsepower; pleasant punch for passing and merging

Cons: It can be thirstier than a regular engine if you have a heavy foot; turbochargers themselves can fail and be costly to replace

HOW TURBO CHARGER WORKS?

                   When people talk aboutr 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 turbos so popular!

In this article, we'll learn how a turbocharger increases the power output of an engine while surviving extreme operating conditions. We'll also learn how wastegates, ceramic turbine blades and ball bearing help turbochargers do their job even better. Turbochargers are a type of forced induction system. They compress the air flowing into the 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.
