(OP)
What is the maximum vibration level that can be accepted in a car engine and the components mounted around the engine. If the maximum level varies depending on the number of cylinders, is there any formula for determining the target natural frequency value ?

Your vibration limits are set by 3 things
1) radiated sound power
2) vibration transmitted to other components such as ancillaries, gearbox, engine mounts for noise problems
3) durability of the engine and ancillaries and other components.
I don't know of any equations that really help.
