SILENCER:
Silencer is used to reduce the noise of exhaust gas /
Smoke.
The exhaust gas is sent through a number of small holes
provided inside the silencer which results in sudden
expansion of exhaust gases.
This results in reduction in exhaust noise.
For specific applications like Power Generation residential
mufflers are used to achieve reduction in noise levels.
INTER COOLER (APPLICABLE FOR TURBO CHARGED INTERCOOLED ENGINES):
Compressed hot air from turbocharger flows through the
tubes of intercooler.
Pusher type radiator cooling fan charges Cold air through the
intercooler fins carries away the heat from compressed hot air
flowing through the intercooler tubes thereby reducing the
temperature of air to the designed temperature levels. This
compressed cold air rushes in to the combustion chamber.
