FUEL FEED DEVICE FOR AN INTERNAL COMBUSTION ENGINE

摘要

The invention concerns a fuel feed device for an internal combustion engine (9), comprising the following elements: an air intake device which includes an intake air-dosing device (16) and is provided with manifold pipes (13) which lead to individual combustion chambers (10); a plurality of fuel injection valves (11) each of which is allocated to a combustion chamber (10); and a central fuel vaporiser (19) to which fuel can be fed by a fuel-dosing device (25). In order to reduce the emission of harmful pollutants during the engine's warm-up phase after ignition, it is proposed that fuel vapour produced in the fuel vaporiser (19) should be capable of being fed downstream of the intake air-dosing device (16, 18) into the air drawn in by the combustion chambers (10).
