Abstract
An exhaust passage extends from an internal combustion engine to conduct exhaust from the engine. A filter is disposed in the exhaust passage to catch particles in the exhaust. A burner is disposed in the exhaust passage at a position upstream of the filter. The burner receives a mixture of air and fuel and burns the mixture to burn off the particles deposited on the filter. The burner includes a vaporizing member and a guide member.
