AIR INTAKE AND EXHAUST SYSTEM
0003
1. DRY-TYPE AIR FILTER (Figure 4, Item 1) filters dust and dirt from the air before it enters the turbocharger and
the engine.
2. EXHAUST PIPE (Figure 4, Item 2) directs exhaust gases from the engine compartment.
3. TURBOCHARGER (Figure 4, Item 3) is an exhaust gas-driven turbine device which increases the amount of
pressure and air entering the intake manifold and engine. Each turbine is secured to a central shaft and is
contained in its own housing. As the exhaust gas passes over the exhaust turbine, it turns the shaft, thus
turning the intake turbine (compressor) which forces air into the intake manifold. The effect is to increase the
engine horsepower.
4. EXHAUST MANIFOLD (Figure 4, Item 4) collects exhaust gas from each cylinder of the engine and directs it
to the turbocharger.
5. INTAKE MANIFOLD (Figure 4, Item 5) distributes the pressurized air to the individual cylinders of the engine.

FUEL SYSTEM
0003
A low pressure fuel pump draws fuel from the tank through an inline fuel filter. The fuel is then pumped through a
fine fuel filter/water separator to the fuel injection pump which supplies fuel to the injectors.
