Abstract
An exhaust purification apparatus includes a regenerative burner for repetitively regenerating a trap element located in the exhaust system of an internal combustion engine. The regenerative burner has a combustion chamber adapted to permit flow of exhaust gases from the engine exhaust conduit to the trap element. A cup-shaped member is disposed within the combustion chamber to define therein an evaporation chamber which has an adequate supply of air-fuel mixture. The cup-shaped member has a peripheral wall formed with cutouts to permit air-fuel mixture from said evaporation chamber into said combustion chamber and also with a hole to permit fuel droplets to fall onto a glow plug located below the cup-shaped member within the combustion chamber. A protective cover is provided to cover the path of dropping of fuel droplets onto the glow plug to prevent air from flowing to cool down the glow plug and deviate the fuel droplets away from the glow plug.
