Abstract

The method involves estimating variation of dilution rate of fuel based on a number of fuel injection phases in combustion chambers, quantity of the injected fuel, the position of pistons in the chambers during the fuel injection and supply pressure of the fuel. The variation of the dilution rate is calculated on a delayed injection phase and a rapid injection phase. An independent claim is also included for a method of controlling a motorization system having an engine and a particles filter.
