A fuel injection system is described for injecting slurry fuels into the combustion chamber of a diesel engine, equipped with a fuel common rail, and fitted with a gas to fuel contactor chamber for dissolving supplementary atomizing gas into the continuous phase of the slurry fuel, at high pressure. Each fuel injector comprises a combined double valve for starting and stopping fuel injection, so that slurry fuel containing atomizing gas is only depressurized when injected into the engine combustion chamber, when such depressurization greatly improves fuel atomization and combustion efficiency. In this way small bore, high speed, diesel engines can be efficiently operated on high viscosity, low cost fuels such as tars from tar sands, tars from coal and biomass, and residual petroleum fuels.
