Q2. Which type of ic engine
Ans. 
Internal combustion engines are classified into two main types: spark ignition (SI) engines and compression ignition (CI) engines.
• Spark ignition (SI) engines use a spark plug to ignite the fuel-air mixture, commonly found in gasoline engines.

• Compression ignition (CI) engines rely on the heat generated by compressing the air in the cylinder to ignite the fuel, commonly found in diesel engines.

• Each type of engine has its...read more

Q1. What is stress ,draw stree strain diagram
Ans. 
Stress is a measure of the internal resistance of a material to deformation, while a stress-strain diagram shows the relationship between stress and strain.
• Stress is the force applied per unit area on a material, measured in units like Pascals or psi.

• Strain is the measure of deformation of a material in response to stress, typically expressed as a percentage.

• A stress-strain diagram plots stress on the y-axis and strain...read more

Q2. Draw different cycles of IC engine and explain in detail
Ans. 
Different cycles of IC engines include Otto, Diesel, Dual, and Atkinson cycles.
• Otto cycle: Ideal cycle for spark-ignition engines, consisting of four processes - isentropic compression, constant volume heat addition, isentropic expansion, and constant volume heat rejection.

• Diesel cycle: Ideal cycle for compression-ignition engines, with four processes - isentropic compression, constant pressure heat addition, isentropi...read more
