Chapter 5, Problem 30R

To determine

To state the device in which fuels are burnt inside chambers called cylinders.

Explanation of Solution

Introduction:

A device that converts thermal energy into mechanical energy utilizing some chemical energy in it is called a heat engine. An example of this engine is a car’s engine.

All heat engines contain two types of combustion engines (either of the two), called internal combustion engine and external combustion engine which burns fuel either inside or outside a set of cylinders. A combustion engine that burns fuels inside a set of cylinders is called an internal combustion engine and the combustion engine which burns fuel outside a set of cylinders is called an external combustion engine. Internal combustion engines are used in all modern-day automobiles and diesel engines while the external combustion engine was used in old fashioned steam engines. Internal combustion engines are considered better than the external ones as they have higher thermal efficiency and consume a little fuel.

Conclusion:

Hence, the device in which fuels are burnt inside chambers called cylinders is called an internal combustion engine.
