Patent ID: 8676475

Claim:
A method for regenerating a diesel particulate filter within a diesel engine system that comprises a combustion chamber defined by a reciprocating piston inside a cylinder, an exhaust valve for cyclically opening the combustion chamber towards an exhaust line, and the diesel particulate filter located in the exhaust line, the method comprising: injecting an amount of fuel into the combustion chamber with at least two consecutive after-injection pulses, each of which starts after the reciprocating piston has passed the top dead center and sufficiently near to the top dead center for the amount of fuel to burn at least partially inside the combustion chamber; and regulating the number of after-injection pulses, wherein the regulating of the number of after-injection pulses comprises correcting the number of after-injection pulses, at least in an available time slot between top dead center of the reciprocating piston and the instant when the exhaust valve opens the combustion chamber.
