FAQs on Hand Written Notes: Combustion of IC Engine - Thermodynamics - Mechanical Engineering

1. What is the combustion process in an IC engine?
Ans. The combustion process in an IC engine involves the rapid burning of the air-fuel mixture inside the combustion chamber, resulting in the release of heat energy that is converted into mechanical work to drive the engine.
2. How does the combustion of fuel contribute to the working of an IC engine?
Ans. The combustion of fuel in an IC engine generates high-pressure gases that expand rapidly, pushing the piston downward and converting the chemical energy of the fuel into mechanical work to drive the engine.
3. What are the factors that affect the combustion process in an IC engine?
Ans. Factors such as air-fuel ratio, ignition timing, engine temperature, and compression ratio can significantly impact the combustion process in an IC engine, affecting its efficiency and performance.
4. How can the combustion efficiency of an IC engine be improved?
Ans. The combustion efficiency of an IC engine can be improved by optimizing the air-fuel mixture, ensuring proper fuel atomization, enhancing combustion chamber design, and using advanced ignition systems.
5. What are the environmental implications of incomplete combustion in an IC engine?
Ans. Incomplete combustion in an IC engine can lead to the formation of harmful pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides, contributing to air pollution and adverse health effects.
