"The bus's engine stopped after the alternator belt snapped under the hood."The possessive noun is bus's (the engine of the bus).
Mainly, yes, but there are minor differences, and of cource the bus engine is usually largest :)
You would have to know the size and type of engine, the age of the engine, the age of the bus and weight of the bus. As a general rule, a diesel engine on a bus would get around 6-15 miles per gallon.
The bus that the Chinese are currently developing is rear engine motor bus. This engine allows the vehicle to move at faster speeds and get to places faster.
Tanks, frags, and mostly guns.

It means the engine is in the rear of the bus or RV.
It depends on what you're trying to say. "In the bus" means that you're inside, or it could refer to a part of the bus that's inside the engine. "On the bus" can mean that you have gotten on the bus and are riding it, or it can mean that you're on top of it!
