FAQs on IC Engines Video Lecture - Thermodynamics - Mechanical Engineering
| 1. What is an IC engine? |  |
Ans. An IC engine, also known as an internal combustion engine, is a type of heat engine that converts chemical energy stored in fuel into mechanical energy. It operates by burning fuel inside a combustion chamber, creating high-pressure gases that move a piston, producing mechanical work.
| 2. How does an IC engine work? | |
Ans. An IC engine works on the principle of internal combustion, where fuel is burned inside the engine to produce energy. The process involves four strokes: intake, compression, ignition, and exhaust. During the intake stroke, fuel-air mixture is drawn into the cylinder. In the compression stroke, the mixture is compressed. Ignition of the mixture occurs in the ignition stroke, resulting in an explosion and a sudden increase in pressure. Finally, the exhaust stroke expels the burnt gases from the cylinder.
| 3. What are the types of IC engines? | |
Ans. IC engines can be classified into two main categories: spark-ignition (SI) engines and compression-ignition (CI) engines. SI engines, also called gasoline engines, use a spark plug to ignite the fuel-air mixture. CI engines, also known as diesel engines, rely on the heat generated by compression to ignite the fuel.
| 4. What are the advantages of IC engines? | |
Ans. IC engines have several advantages. They provide high power output, making them suitable for various applications such as automobiles and power generation. They offer good fuel efficiency and can run on a wide range of fuels. IC engines are also compact, easy to maintain, and have a longer lifespan compared to other types of engines.
| 5. What are the limitations of IC engines? | |
Ans. IC engines have some limitations. They produce harmful emissions like carbon dioxide, nitrogen oxides, and particulate matter, contributing to air pollution. IC engines also have lower thermal efficiency compared to other types of engines. They require a constant supply of fuel and may generate noise and vibrations during operation. Additionally, the combustion process in IC engines can lead to wasted energy in the form of heat.
