2. Make sure you speak some sense at least thrice in the GD, and you're through.
3. They never once interrupted me in the PI. They waited for me to complete what I was saying, and then the next question was based on my last two sentences! So be very careful of what you're saying esp. while answering the technical questions. Most importantly, be very genuine throughout the interview- speak your heart out- and don't worry about how it's going, in the middle of it!
Good luck."

- Q1. How the diesel engine works?
- Ans.
Diesel engine works by compressing air in the cylinder and injecting fuel at the right time to ignite the mixture.
Air is compressed in the cylinder by the piston
Fuel is injected into the cylinder at the right time
The heat generated by the compressed air ignites the fuel
The expanding gases push the piston down, creating power
Diesel engines are more efficient than gasoline engines
- Q2. What do you mean by cc
- Ans.
CC stands for carbon copy, a term used in email communication to indicate additional recipients of a message.
CC is used to send a copy of an email to someone other than the primary recipient
CC recipients are visible to all other recipients of the email
CC is often used for informational purposes or to keep others in the loop
CC can also be used to show transparency in communication
- Q3. What is the compression ratio
- Ans.
Compression ratio is the ratio of the volume of gas in a cylinder when the piston is at the bottom of its stroke to the volume of gas when the piston is at the top of its stroke.
It is a measure of how much the engine compresses the air/fuel mixture before ignition.
Higher compression ratios can lead to better fuel efficiency and more power.
Compression ratio is calculated by dividing the volume of the cylinder at bottom
- Q4. What is swept volume
- Ans.
Swept volume is the volume of space swept by a piston in an engine cylinder during one stroke.
It is the volume of the combustion chamber when the piston is at the bottom of its stroke subtracted from the volume of the combustion chamber when the piston is at the top of its stroke.
It is used to calculate the engine displacement.
For example, a four-cylinder engine with a 500cc swept volume has a total displacement of 2,0...
