Abstract
A method is provided for regenerating a diesel particulate filter within a diesel engine system that includes, but is not limited to at least a combustion chamber defined by a reciprocating piston inside a cylinder, at least an exhaust valve for cyclically open the combustion chamber towards an exhaust line, and the diesel particulate filter located in the exhaust line, wherein the method comprises injecting an amount of fuel into the combustion chamber by means of least two consecutive after-injection pulses (AIP-AIP), each of which starts (SOI) after the piston has passed the top dead center (TDC), and sufficiently near to the latter for the fuel to burn at least partially inside the combustion chamber.
