A method for regenerating a particulate filter communicating with exhaust gases of an internal combustion engine 12 is provided. The method includes indicating that the particulate filter 48 needs to be regenerated. The method further includes adjusting the throttle valve 18 to decrease an amount of air inducted into one of the engine cylinders to increase a temperature of the exhaust gases while maintaining an engine speed above a predetermined engine speed. The method further includes increasing the speed of the engine 12 and injecting a predetermined amount of fuel into one of said cylinders late in a power stroke of the cylinder to further increase the temperature of the exhaust gases to regenerate the filter 48.

[ We claim:] [30.]30. An article of manufacture comprising:a computer storage medium having a computer program encoded therein for controlling a regeneration of a particulate filter communicating with exhaust gases of an internal combustion engine, said engine having cylinders, an intake manifold providing air to said cylinders, and a throttle valve controlling an amount of air entering said intake manifold, said computer storage medium comprising:code for indicating said particulate filter needs to be regenerated;code for adjusting said throttle valve to decrease an amount of air inducted into one of said engine cylinders to increase a temperature of said exhaust gases to thereby regenerate said particulate filter;code for maintaining an engine speed of said engine above a predetermined engine speed during said adjusting of said throttle valve; andcode for maintaining an air/fuel ratio of an air/fuel mixture combusted in one of said cylinders above a predetermined air/fuel ratio.
