Question

The control of cooling system in air-cooled system is not easier than in water-cooled system.

(a) True

(b) False

I have been asked this question in an international level competition.

My enquiry is from Air Cooled Systems topic in section Heat Rejection and Cooling of IC Engine

Answer 1

The correct answer is:

(b) False

The control of the cooling system in an air-cooled engine is generally considered easier than in a water-cooled system. This is because air-cooled systems rely on the direct flow of air over the engine components (such as the fins on the cylinder head), and there are no complex coolant pumps, thermostats, or radiator systems to manage. In contrast, water-cooled systems require more components, including a pump, radiator, thermostat, and coolant fluid, all of which need to be controlled and maintained. Therefore, air-cooled systems tend to have simpler cooling management.
