Which one is more efficient? A four stroke engine or a two
stroke and why?

Answer Posted / manoj prabahar

Four stroke engine produces less pollution than two stroke,
since there is no valves the the little amount of fresh
charge escapes so it gives less mileage, but power produced
is more in two stroke since cycle of operation is 2, rather
in 4 stroke its 4. The power produced in 2 stroke engine is
app twice the 4 stroke for the same capacity engine....

Hello there, Im a Mechanical Engineer. I passed out in 2010 and have worked for 6 months in the Middle East as a Trainee Engineer. Im now in India and due to appear for an Interview for a firm in the Middle East. The post is of an Automobile Engineer. Im kinda nervous as to what to prepare for the interview. The training which I got was in different areas ranging from technical to managerial aspects. What I mean to say is that that was more of a crash training, where I couldn't stick to one section alone. The interview which Im attending is more of a technical one. What I would like to know, how and what I should be preparing? I have two weeks for the preparation. Should I go through the normal automobile aspects or everything in random. PS: I have excellent communication skills, the one area in which I'm very confident.
