ABSTRACT:
A method and apparatus is disclosed for periodically oxidizing particulate matter trapped in and on an exhaust gas purifying device used in conjunction with a diesel engine. Fuel normally delivered to selected combustion chambers is diverted to a fuel burning device associated with the purifying device. The diversion deactivates the combustion process in the selected chambers. The diverted fuel is then burned by the burning device to increase the exhaust gas temperature flowing through the purifying device and effect oxidation of collected particles.
