Combustion apparatus for vehicle

摘要

A combustion apparatus for a vehicle for regenerating a filter provided in an exhaust gas passage of an engine by burning and removing fine particles in the exhaust gas comprising an air supply passage for coaxially supplying air along the outer periphery of a fuel injection nozzle, a shut-off valve mounted at the downstream side end of said combustion chamber for preventing reverse flow of the exhaust gas, and a controller for allowing the inflow of the coaxial air for a predetermined period of time after stopping the fuel supply from the fuel injection nozzle and then closing the shut-off valve.
