Abstract
The invention relates to a process and a device for improving vaporization of a fuel injected into an internal-combustion engine so as to decrease harmful discharges in the exhaust gases . The engine comprises at least one cylinder (1) with an inlet pipe (6) , an exhaust pipe (4) , a secondary conduit (7) provided with a plug connecting for example the two pipes together so as to recycle towards the inlet pipe a fraction of the waste gases richer in unburned hydrocarbons. The process implemented here essentially consists in placing a fuel injector (9) in proximity to the intersection of inlet pipe (6) and secondary conduit (7) so as to take advantage of the high temperature of the recycled gases to vaporize fuel better and drive it towards the combustion chamber.
