Mr. Moizkhan A. Fadwala completed his term work in mechanical engineering in October 2015. The document then discusses the cooling system used in internal combustion engines. It explains that the cooling system maintains optimal engine temperature to allow for smooth operation while protecting the engine. It describes the key components of a liquid cooling system like the water pump, coolant, radiator and thermostat. It also discusses air cooling systems that use fins and baffles to increase heat transfer from the engine through convection.
