Cooling System Flashcards
1
Q
What is the function of the cooling system?
A
To maintain the engine’s optimal operating temperature by removing heat
2
Q
What is the role of the radiator?
A
Consists of inlet pipe for heated liquid and outlet pipe for cooled liquid
Cools liquid through high-efficiency heat exchange process
3
Q
How is heat removed from the engine?
A
Ducts are filled with coolant which removes heat from cylinders
4
Q
What is the role of the water pump?
A
Circulates coolant in a closed loop and rotated by a belt drive
5
Q
What is the role of the thermostat?
A
Divides system in 2 circuits
Longer one uses radiator, Shorter one is where cool coolant passes
6
Q
What are key features of the air cooling system?
A
- Air is the medium
- Cooling fins transmit heat
- Found in smaller engines
- Cheaper
- Easier to install
- Lower efficiency
- Noisy at high fan speeds
7
Q
What are the key features of the liquid cooling system?
A
- Coolant is the medium
- Coolant absorbs heat and transmit it to radiator
- Found in larger engines
- More expensive
- Higher efficiency
- Quiter operation
