The
Basic function of the turbocharger is essentially the same as the
first turbo designed by the Swiss engineer, Alfred Buchi.
A
Turbocharger consists of six basic components, the turbine wheel
an shaft (hot wheel), a compressor wheel (cold wheel) the bearig
housing and bearing system, the compressor and turbine housings
and the actuator and wastegate assembly. The shaft of the turbine
wheel runs though journal bearings that are lubricated by engine
oil.
A
turbocharger very simply is an air pump designed to operate on the
normally wasted engine exhaust gas energy. These gases drive the
turbine wheel and shaft which is coupled to the compressor wheel.
This rotating grou rpvides a high volume of air to the engine combustion
chambers. Under load, turb rotating group speed often exceeds 200,000
revolutions per minute. Turbine exhaust temperatures can easily
surpass 1800 degrees Fahrenheit.
Although precision built, a turbocharger is basically a very simple
but durable component. It does, however, require maintenance and
care as any other piece of working machinery.
