Exhaust line for diesel engine of motor vehicle, has fuel introducing device comprising fuel vaporizer equipped with vaporizing chamber, and heating unit partially located inside vaporizing chamber to vaporize liquid fuel

摘要

The exhaust line (5) has an exhaust manifold (19) provided with exhaust gas inlets (21). A fuel introducing device (29) introduces liquid fuel i.e. diesel, inside the manifold. The fuel introducing device has a fuel vaporizer (47) equipped with a vaporizing chamber (55). The vaporizing chamber has a liquid fuel inlet (57) and a vapor outlet (59) emerging inside the manifold. A heating unit i.e. spark plug (61), is partially located inside the vaporizing chamber to vaporize the liquid fuel.
