How do I find tail number?

How do I find the tail number of an aircraft flown on a regular commercial flight? All I can find is the flight number and the type of aircraft. Specifically I am looking for the engine type.

Thanks!

Or, given the operator and aircraft type, someone may be able to tell you which engine type they use.
