Water cooling system

 
• In this type of engine water or coolant (heavy water) is used as a cooling medium. These engines are called “water cooled engines”. The liquid is circulated around the cylinders by means of jacket provided, to absorb heat from the cylinder walls and further the heated water is conducted through a radiator which helps in cooling the water as shown in Fig. 5.1.

There are four common methods of water cooling:
i. Open jacket or hopper method
ii. Thermo syphon method
iii. Forced circulation method
iv. Pressurized cooling
