Turbocharging
SILVER 90 - 100.4
The turbocharger assembly covers the function of forcing more air
into the cylinders. This also allows the diesel fuel delivery capacity
to be proportionally increased.
Mixture increase is necessary to obtain greater engine power.
The turbocharger assembly is an extremely simple and rational
design and consists of a turbine and a compressor.
The turbine is operated by the exhaust gases from the engine (in
this way, a part of the gases’ kinetic energy which otherwise would
be wasted is recovered). The turbine drives the compressor, which
compresses the air sucked in the cylinder intake duct through the
filter.
Tests
A precise test on turbocharger efficiency can only be performed
on a test bed.
Tests performed with turbocharger mounted on engine can only
give approximate results.
Before starting checking operations make sure the engine fuel
supply system is operating correctly.
