I am writing a paper, need some review. I want to send it to IEEE, without the name of my co-authors. I might get acceptance. I need to know, in that case, will I be allowed to add my co-authors or not?

Short answer: Hell no!
Depending on the editorial policies of the venue you submit, they may or may not allow to add co-authors during the review process. Some may even accept you to add co-authors after acceptance of the paper.
However, note that in all cases, it is unethical not to have a correct/honest list of co-authors at time of the first submission. All persons who have made significant scientific (or “intellectual”) contributions to the work should be co-authors in the submitted version of the paper.
“Hiding” co-authors during the first submission, even if you intend to add them at a later point, is a clear ethical violation. It probably also violates the journal's (or conference's) policy, which typically stresses the importance of having an appropriate authors' list (and even sometimes provides criteria for authorship).
The reason that editors may allow you to add authors is for special cases or circumstances. The main reason why it would be used is when, during revision of the work to address reviewers' comments, someone who wasn't a co-author of the initial manuscript has been brought onto the team. For example, if you asked someone to run some extra analyses and his contribution warrants authorship of the revised manuscript.
I agree with F'x's answer, but let me expand on it a little: intentionally submitting a paper without listing your coauthors is a potentially career-ending mistake. If I caught you doing that at a journal I edit (or as a referee), I would fully inform everyone - your coauthors, department head, university administration, etc. - and I expect it would lead to severe consequences, such as expulsion from grad school or tenure denial. Ethical violations vary in how serious they are, and deliberately omitting coauthors is among the most serious.
Even if you confess and ask for your coauthors to be added, people may not believe you always planned to add them. Instead, some people will suspect that you initially intended to take all the credit but lost your nerve or feared getting caught. You may know that was never your plan, but your word won't mean much when you're already confessing to something unethical.
It will be even worse if you get caught during the process. For example, one of the referees might already be aware of who is involved in this work, or might even be a coauthor. If they turn you in, you'll be in a particularly bad situation.
In either case, your coauthors will likely be furious with you. They presumably don't think the paper is ready to submit (if they do, then you should submit it with their names on it!), and they also don't want it circulated with just your name on it. Regardless of the journal's policies, you'll have to answer to your coauthors.
Even if you manage to salvage your career, this will stay with you forever. In short, don't do it.
As @F'x and @AnonymousMathematician said, don't do that by any means.
If you feel there is some good reason that @Suresh cannot find then on the basis of that reason you can request a double-blind review.
Due to the way you worded the question, my guess is that you don't have good reasons to do that. You should agree with your co-authors whether you want to send a paper or not before sending it for review.
Besides of the ethical reasons provided, there could be legal consequences, AFAIK you are not the holder of the copyright of what your co-authors did, and if you disclose, publish or attempt to publish some information without their consent then they could start legal actions. If you had their consent, holding their names for the review would be very dodgy and ruin your reputation.
Therefore, to answer the question: "will I be allowed to add my co-authors or not?", the answer is "no", and it doesn't really matter if you try to add them or omit them, this has many chances of backfiring in a dreadful way. Hopefully you didn't send it already, if you did and no review was started then withdraw it asap. If the reviews started, then start to apologize deeply to everybody.
In general this depends on the conference regulations, so the advice is to check them.
Usually you must put information about all authors before the submission deadline. For instance, here are the rules on EDAS submission system regarding this matter.
You can add other authors later and you can change the order of authors. Note that some conferences do not allow that you add or delete authors after the submission deadline, to prevent that authors try to defeat the conflict-of-interest detection mechanisms by omitting authors.
