Automatic fuel

I don't understand your question. But, I want to say that Water is not inflammable also it is incompressible. So it cannot be used as a fuel.

In case of Diesel, it can be compressed and can be ignited. So it is used as a fuel.

@farjand, may be the user is trying to take our attention towards the chemical side of both these compounds.
@elumalaime, nice riddle. Please give us some clue to decode the answer.

ElumalaimeYou will find fuel from water. What is in diesel,what is't in water. You will search this matter and will you finish this project...

The only way to get fuel from water is to dissociate it into Hydrogen and Oxygen. Once that is done the rest is trivial.
