HOW A TURBOCHARGER WORKS

The turbocharger has been the first choice when it comes to enhancing an engine's efficiency and power output. It has been used for decades from cars to ships and from aircraft to helicopters. The scope of the turbocharger is to force extra compressed air into the combustion chamber of an internal combustion engine, and proportionally more fuel, in order to gain power output due to the higher air/fuel mixture. The theory behind it is simple, but the turbocharger as a device is anything but simple. The shear stresses and temperatures that a turbocharger is exposed to maximises the necessity for good quality manufacturing materials and the need to obey all engineering tolerances given by the manufacturer. Failure to do so may result in catastrophic failure of the turbocharger itself and consequently of the machinery it's been installed to.
