Abstract
A method and apparatus for regenerating exhaust treatment devices. Incomplete combustion products may be selectively provided in at least one cylinder of multi-cylinder internal combustion engine. This may then be followed by directing the products to an engine exhaust treatment device. The temperature of the engine exhaust treatment device may then be increased due to exposure to the products of incomplete combustion. The catalyst in the converter may then be regenerated due to the temperature increase.
