01 ENGINE

Turbo

Turbochargers consist of a housing, a blade assembly, inlet ducts for low pressure

air and outlet ducts for high pressure air, an intercooler, oil inlet and return, coolant

inlet and return, and boost control circuits.

The turbine blade is on the exhaust side of the turbocharger and the compressor

blade is on the intake side of the turbocharger. The turbine blade is spun by exhaust

pressure.The compressor blade spins and pressurizes the intake air.

The hot/high pressure air coming out of the turbo is sent to the intercooler to cool it

and make it denser.

The shaft between the turbocharger’s blades rides on bearing surfaces and a thin

ﬁ lm of oil. The turbo’s center upper housing has an oil feed line that connects to the

engines lubrication system to provide pressurized oil. On the bottom of the turbo

housing is an oil drain line to return oil back to the engines crankcase.
