Why does an internal combustion engine have to run on liquid fuel?
I have a full knowledge of how petrol and diesel engines work so I know that it is far easier to get a liquid fuel into the combustion space than it would be a solid fuel. However this does not mean that that it would be impossible to introduce a solid chemical fuel broken down into a light powder. The problems would be to identify a suitable fuel and its costs. It would obviously be necessary to dispose of combustion by-products with minimal polluting effects. Does anyone have thoughts on this or do you think its a non starter?
I would appreciate any thoughts.
