Gas prices here is so expensive now 4$ a gallon it would be much cheaper if I used natural gas. and I want to experiment my experimental engine for testing. by putting pressure regulator to the tank of compressed natural gas and directly connect it with the intake manifold by a hose.
Is there other modification to the engine aside this

Yes! Modify your engine with a burn unit and an EKG!
Dude! Auto engines that run on natural gas are SERIOUSLY modified by PROFESSIONALS! You do not have the knowledge or capability to do it on your own.

If you happen to have compressed natural gas, it would probably work just fine. You'd have to fool with it to get the mixture correct for the various throttle settings; there are carburetor kits available that'll do this for you.
Note that compressed natural gas is not the propane you use for your backyard grill. Compressed natural gas requires an elaborate refrigerated tank because it's made of methane, which doesn't liquify so easily. Propane is far better behaved, and you can run a car on it as well.
Note that you probably won't save a dime with either of these gases. They're both expensive, and you'll eventually want to pay your fuel tax before the authorities catch up with you.

Yes, compressed natural gas can be used (and has been used) directly. Only minor changes are needed to the engine to use natural gas.

Not quite that simple . First natural gas will only compress a little and it becomes like trying to compress water.. The tank is very large.

I'm studying chemistry and I can't see anything wrong with it. As far as hydrogen goes its too expensive and hard to capture and facilitate. I would be more confident w/ a liquid in my car. I don't know anything about engines or natural gas. Keep at it and keep at it I guess... Good luck and best of safety! Also, I thought about biodiesel buts that the worst $!
