1.	The efficiency of IC engine is normally of the order of1. 15 - 20%2. 20 - 25%3. 25 - 30%4. 30 - 35%
Answer» Correct Answer - Option 4 : 30 - 35% Explanation: Steam engine: The heat engine that converts heat energy of steam into mechanical energy to perform many works is called a steam engine. Internal combustion engine: An engine that converts chemical energy into mechanical energy by combustion of a fuel and generates mechanical power. Internal combustion engine: The combustion of fuel takes place inside the engine cylinder. It has a noisy operation. The working pressure and temperature inside the engine are very high. It does not require a boiler and other components for energy transfer, therefore it is light and compact. It has a thermal efficiency of 30 to 35 %. It can start instantaneously.
