I would like to know if there is any possibilities of running an engine without fuel?
That really depends on how you define "fuel" for example any source of energy could be called the fuel, also you may want to take a look at electric cars which don't require conventional fuel. Also a future possibility that may interest you is solar cars which convert sunlight into energy that is used as the cars fuel, however i believe that they may only use the solar as a supplementary source of energy.

That would be a question to post in the General Physics forum. I'll watch for the discussion there. :)
Your question is vague, but it appears that you are asking if there is a possibility of an engine running without any power source. No.
