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.
