A dual-fuel injector is provided which allows precisely controlled injection of liquid and slurry fuels into an engine or the like, which prevents separation of solid material from the liquid carrier in the slurry fuel, and which prevents abrasion of selected surfaces of the injector by the solid material. The preferred injector includes a housing and an electronically actuated liquid and slurry fuel assemblies. In operation, pressurized liquid fuel supplied to the injector is used to amplify the injection pressure of the respective fuels for discharge through respective nozzles. The slurry fuel is continously circulated through the injector to prevent separation of the solid material from the liquid carrier and liquid fuel is used to purge selected surfaces of the injector to prevent the abrasion thereof by the solid material in the slurry fuel.
