Air moves without restriction through the air cleaner and intake manifold (Figure 3-1 and 3-2) to the combustion chamber. The chamber is filled with air, then the air is compressed to a temperature that will ignite the diesel fuel when it is injected.
The intake manifold provides a mount for the air cleaner and EGR valve. Since the intake “ bridges” the injection pump, it must be removed when the injection pump requires removal.
The air cleaner assembly has a tuning chamber on the air inlet snorkel, called a resonator. It reduces air intake noise.
Figure 3-3 shows the available option K46 pre-cleaner chamber.
Figure 3-4 shows the air cleaner arrangement on the G-Van.
