Can I use a 220v engine to build up a RC car?
The motor you have found is probably AC and runs at a high voltage (although there is no harm in trying it out with a low DC voltage as mentioned in case it is not 220VAC driven).
Whilst in theory it is possible to use any motor if you drive it correctly, this is not the right type for an application such as this. The high voltage makes it needlessly dangerous, and would need to be created from a lower voltage DC source (i.e. a battery)
So rather than convert a low voltage DC source, you are better off using a low voltage DC motor. If you check on any RC hobby store site, you should see many suitable options, and the batteries to power them (plus servos, and other things you need for an RC car)   

Here is one such motor from Hobby King which runs from 7.4V to 11.1V DC:
