INTRODUCTION
INTRODUCTION
In order to optimize the engine's performance, it is necessary to compress and to
regulate the temperature of the combustion air.
This is carried out by the use of a turbocharger and an air cooler
This paragraph is a general description of the function of engine parts in the air inlet
and exhaust system.
The main parts of the air inlet and exhaust system are shown in the general diagram
(paragraph 8F). These main parts have a number which corresponds to the number
in the diagram. This number is placed between brackets in the description below.
The supply of inlet air can be done:
-- Via the air filter of the turbocharger. In this case large volumes of air need to be
delivered close to the turbocharger intake (approx. 2 times the combustion air
usage).
-- Via an air intake air pipe tube from outside with a separately installed air filter.
Fresh air that contains too much dust and/or chemical pollution must be filtered
by a separately installed filter.
When the air filter becomes contaminated the resistance of the air filter increases.
If the air filter is defective or the filtering of the air is insufficient a reduction of the life
of engine components can be the result.
The turbocharger consists of a turbine and a compressor on one shaft. Energy from
the exhaust gases drives the turbine. The exhaust gasses expand (reducing the
temperature).
The compressor, driven by the turbine, compresses the inlet air (increasing the
temperature).
See the SUB--SUPPLIERS MANUAL for a detailed description of the turbocharger.
