Why do some combustion vehicles only run on a specific type of fuel?

Question

To my knowledge combustion is just burning fuel and if all you need is fire to burn a fuel shouldn’t any type of fuel work in any type of car?

That’s a lot like asking why some barbeque grills use charcoal, some use propane, and other use wood.

Yes, they are all fuels, but they each burn differently. Different types of grills are designed to work best with specific fuels. So are different types of car engines.
