3. Internal combustion engines require a cooling system to function properly, which maintains the engine temperature at an appropriate value. Neither too high nor too low. There are several systems to control this temperature, the two best known are: • The classic one that uses a thermostat that regulates the flow of coolant (water), and where the fan is mechanically coupled to the engine. • In more recent vehicles, in addition to the thermostat, a temperature controller is used that turns an electric fan on and off. Select one of the two systems mentioned above and: a) Explain how it works, using diagrams. b) Make the typical block diagram of a feedback control system, identifying the components of the system. c) Classify the control system.

Transcribed Image Text:3. Internal combustion engines require a cooling
system to function properly, which maintains
the engine temperature at an appropriate value.
Neither too high nor too low. There are several
systems to control this temperature, the two
best known are:
• The classic one that uses a thermostat that
regulates the flow of coolant (water), and where
the fan is mechanically coupled to the engine.
• In more recent vehicles, in addition to the
thermostat, a temperature controller is used
that turns an electric fan on and off.
Select one of the two systems mentioned above
and:
a) Explain how it works, using diagrams.
b) Make the typical block diagram of a feedback
control system, identifying the components of the
system.
c) Classify the control system.
