摘要： A method for determining the quantity of filling components in a cylinder of an internal combustion engine. The cylinder is connected to an air supply via an inlet valve and to an exhaust gas conduit via an outlet valve. The method includes the steps of obtaining an exhaust gas back pressure at a specified point in time when the outlet valve is opened during a work cycle of the internal combustion engine and calculating the quantity of the filling components at the specified point in time on the basis of the obtained exhaust gas back pressure. A controller is also provided for carrying out the method and a motor vehicle is also provided that includes the controller.

摘要： Methods and systems are provided for addressing pre-ignition by mechanically varying a piston displacement within a combustion chamber. In response to pre-ignition, a static compression ratio may be reduced until a threshold lower compression ratio is reached. Further pre-ignition is then addressed with enrichment, thereby reducing the amount of pre-ignition mitigating enrichment required overall.

摘要： Systems and methods for detecting and controlling knock in an engine are presented. In one example, engine knock sensors are selected based on whether or not certain cylinders are activated and combusting air and fuel or deactivated and not combusting air and fuel. Output of selected knock sensors is the basis for adjusting engine spark timing.

摘要： A system according to the principles of the present disclosure includes a first burn duration module and a spark control module. The first burn duration module determines a first duration of at least a portion of a fuel burn within a cylinder of an engine from a first time when a first predetermined percentage of a mass of fuel within the cylinder is burned to a second time when a second predetermined percentage of the fuel mass is burned. The spark control module controls a spark plug to adjust spark timing of the cylinder based on the first burn duration.

摘要： A first-half combustion period, for example, is estimated/evaluated, with a required accuracy, more simply than the conventional art, while reducing man-hours to produce a heat generation rate waveform of an internal combustion engine. Within a combustion period of an air-fuel mixture, a period from an ignition time FA to a heat generation rate maximum time dQpeakA where the heat generation rate is maximum is defined as the first-half combustion period a that is one of characteristic values of the heat generation rate waveform. The first-half combustion period a is estimated based on an in-cylinder volume at the heat generation rate maximum time, and furthermore by being corrected using an exponential function of the engine rotation speed with a value depending on a tumble ratio as exponent. Thus, the heat generation rate waveform is produced using the estimated first-half combustion period a.

摘要： Methods and systems are provided for adjusting spark and/or fuel injection to a cylinder based on late combustion, partial burn, or misfire in a neighboring cylinder. A pressure sensor coupled to a cylinder exhaust port is used to sample exhaust pressure pulsations over a cylinder exhaust valve event, and accurately estimate an amount of residuals generated in and released from the cylinder as well as residuals received from the neighboring cylinder. Mitigating actions are performed in the cylinder in accordance before the occurrence of a pre-ignition event.
