Forced Circulation method
Forced Circulation method

-
In this method, a water pump is used to force water from the radiator to the water jacket of the engine (Fig. 5.3). After circulating the entire run of water in jacket, water comes back to the radiator where it loses its heat by the process of conduction. To maintain the correct engine temperature, a thermostat valve is placed at the outer end of cylinder head. Cooling liquid is by-passed through the water jacket of the engine until the engine attains the desired temperature. Then thermostat valve opens and by-pass is closed, allowing the water to go to the radiator.
