The idea of mult fuel engine isn't new - the UK army had Rolls Royce develop a series of them for army jeeps, turucks etc. to allow flexibilty in a war zone but LPG was not included then.
The claim that it doesn't need DEF etc is interesting so I wonder if it is only for of road applications or for makets where emissions regs for trucks are stl minimal ?
