The invention relates to an air-cooled internal combustion engine comprising a fan for forced cooling, whereby water is injected into the cooling air flow of the internal combustion engine and serves to additionally cool the engine by evaporation. A fire-fighting vehicle is operated with this air-cooled internal combustion engine and comprises a conical, turbine-operated extinguishing and cooling fan tube with water injection for fire-fighting and for cooling the tunnel air. This results in the provision of a particularly rugged, air-cooled internal combustion engine combined with a fire-fighting vehicle for use in complicated operating conditions involving fires in parking garages, mining galleries, tunnels, etc.
