AIR INLET AND EXHAUST SYSTEM
(Sheet 1 of 1)
Air inlet and exhaust system components are:
INLET MANIFOLD. Mounted on top of the engine the manifold
distributes the compressed air from the turbocharger. There are
eight passages, one going to each cylinder.
CYLINDER HEADS. Contains the valve components necessary for
the engine to intake oil and exhaust burnt fuel. For each cylinder
there are two intake valves and two exhaust valves. The fuel
injection nozzles are located in the cylinder heads to inject the fuel
into the cylinders.
EXHAUST MANIFOLDS. Located on each side of the engine, the
through the turbocharger.
AIR CLEANER. A dual element, dry type. Outside air is drawn
MUFFLER AND EXHAUST PIPE. Connects to the outlet of the
through the filter elements by a vacuum created in the turbocharger.
turbocharger to quiet and carry the exhaust gases away from the
When one, or both, of the elements get clogged, a "high vacuum"
switch in the air cleaner housing turns on the PLUGGED AIR FILTER
indicator on the instrument panel.
TURBOCHARGER. Pulls in the clean air from the air cleaner and
compresses it. The turbocharger is driven by the engine exhaust
gases; the exhaust gases turn the turbine wheel, which causes the
compressor wheel to turn. The compressed air then goes to the inlet
manifold of the engine. As the load on the engine goes up, more fuel
is supplied to the engine. This causes more exhaust which turns the
turbocharger faster supplying the engine with additional air.
