Answer / chobe bapu

it is the extra ammountof air which is require for the
combustion of fuel in an engine because mixture of air and
fuel is not homogenous.

Answer / ahmed el- wakeel

In combustion there are two types of air
1- Theoretical air :- the min amount of air that supplies
enough oxygen for complete combustion. The mixture in this
case is called stoichiometric.
2- Actual air:-is more than the theoretical air by the
value of excess air.
So excess air is the amount of air supplied over or above
the theoretical air.
EX. 150% theoretica air means that the actual air supplied
for combustion is 1.5 times the theoretical air. Also means
that there is 50% excess air and it also can be expressed
in terms of "excess air factor"=1.5

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.
