The compression ratio for a particular engine is limited by how strong the
engine block is. Too much pressure (compression) and something will break.
The best fuel will also depend on the design of the engine. But as a
general rule, the greater the energy content of the fuel, the greater the
efficiency (at least in terms of miles per gallon or km per liter). Water
has a low energy content and would not make a good fuel for example.

The limits to compression ratio are based on the knock limits of the fuel.
Knock is the term used to describe the auto ignition that occurs when a fuel
ignites because the pressure in the cylinder is such that combustion occurs.
In a spark ignited…
