(d) all of the mentioned

The question was asked in homework.

The doubt is from Liquid Cooling Systems in division Heat Rejection and Cooling of IC Engine

Answer 1

The correct answer is:

(d) all of the mentioned

The various methods used for circulating water around the cylinder and cylinder heads in liquid cooling systems include:

• Thermo-syphon cooling: This method relies on natural convection, where hot coolant rises and is replaced by cooler liquid as it circulates through the system.
• Forced or pump cooling: In this method, a pump is used to circulate the coolant, providing better control and flow rate, which is more efficient for high-performance engines.
• Cooling with thermostatic regulator: This method involves using a thermostat to regulate the coolant flow, maintaining the engine temperature within a specified range.

All of these methods are used in different types of liquid cooling systems depending on the engine's requirements.
