Title: METHOD AND CONTROLLER FOR DETERMINING THE QUANTITY OF FILLING COMPONENTS IN A CYLINDER OF AN INTERNAL COMBUSTION ENGINE
Abstract:
The invention relates to a method for determining the quantity of filling components in a cylinder (1) of an internal combustion engine. The cylinder (1) is connected to an air supply (13) via an inlet valve (12) and to an exhaust gas conduit (15) via an outlet valve (14). The method has the steps of obtaining (31) an exhaust gas back pressure at a specified point in time when the outlet valve (14) is opened during a work cycle of the internal combustion engine and calculating (32) the quantity of the filling components at the specified point in time on the basis of the obtained exhaust gas back pressure. The invention further relates to a controller for carrying out the method and to a motor vehicle comprising such a controller.
