2. Radiator (engine cooling) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(engine_cooling)

   Electric fans are controlled by a thermostatic switch or the engine control unit. Electric fans also have the advantage of giving good airflow and cooling at low engine revs or when stationary, such as in slow-moving traffic. Before the development of viscous-drive and electric fans, engines were fitted with simple fixed fans that drew air ...

3. Fan clutch - Wikipedia

   en.wikipedia.org/wiki/Fan_clutch

   Engine fan with viscous drive. A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.

4. Crankcase ventilation system - Wikipedia

   en.wikipedia.org/wiki/Crankcase_ventilation_system

   On slow-moving delivery vehicles and boats, there was often no suitable air slipstream for the road draught tube. In these situations, the engines used positive pressure at the breather tube to push blow-by gases from the crankcase. Therefore, the breather air intake was often located in the airflow behind the engine's cooling fan. [1]

5. Internal combustion engine cooling - Wikipedia

   en.wikipedia.org/wiki/Internal_combustion_engine...

   Cooling system regulation includes adjustable baffles in the air flow (sometimes called 'shutters' and commonly run by a pneumatic 'shutterstat'); a fan which operates either independently of the engine, such as an electric fan, or which has an adjustable clutch; and a thermostatic valve or a thermostat that can block the coolant flow when too ...

6. Heater core - Wikipedia

   en.wikipedia.org/wiki/Heater_core

   The internal combustion engine in most cars and trucks is cooled by a water and antifreeze mixture that is circulated through the engine and radiator by a water pump to enable the radiator to give off engine heat to the atmosphere. Some of that coolant can be diverted through the heater core to give some engine heat to the cabin, or adjust the ...

7. Radiator - Wikipedia

   en.wikipedia.org/wiki/Radiator

   The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, [1] [2] having received a radiator patent in 1857, [3] but American Joseph Nason developed a primitive radiator in 1841 [4] and received a number of U.S. patents for ...

9. Radial engine - Wikipedia

   en.wikipedia.org/wiki/Radial_engine

   Kurt Tank designed a new cooling system for this engine that used a high-speed fan to blow compressed air into channels that carry air to the middle of the banks, where a series of baffles directed the air over all of the cylinders. This allowed the cowling to be tightly fitted around the engine, reducing drag, while still providing (after a ...
