AIR INLET AND EXHAUST SYSTEM
8A INTRODUCTION
The combustion air passes the turbocharger and flows into the air cooler. The air
cooler cools the combustion air to receiver temperature.
In the air cooler there is a slight pressure drop. After the air cooler the combustion air
flows via the air receiver into the cylinders.
The reduction of the combustion air temperature, (raising of the specific mass), has
a good effect on the efficiency of the engine and on the temperatures in the engine.
When the cooling water temperature in the air cooler is too low, the receiver
temperature drops too much, resulting in a not--optimal combustion.
Contamination of the air cooler, the air part or the water part, gives a reduction in
capacity of the air cooler. As a result, the receiver temperature rises.
Contamination of the air part of the cooler decreases the pressure in the receiver.
See the Sub--suppliers manuals for a detailed description of the air cooler.
The exhaust manifold can expand in all directions. There are compensators between
the exhaust manifold and the turbocharger and in between the exhaust manifold of
each cylinder configuration.
All parts of the exhaust manifold are insulated and protected by a steel plate cover.
