Definitions
- the invention relates to a method for operating an internal combustion engine with a plurality of combustion chambers, in which the combustion chambers are filled with fuel and air or with a fuel / air mixture.
- the invention also relates to an internal combustion engine with a plurality of combustion chambers which can be filled with fuel and air or with a fuel / air mixture. Furthermore, the present invention relates to a control device for such an internal combustion engine.
- the invention also relates to a memory element for a control device of an internal combustion engine, on which a computer program is stored, which can run on a computing device, in particular on a microprocessor.
- the memory element is designed in particular as a read-only memory, as a random access memory or as a flash memory.
- the invention also relates to a computer program.
- the invention relates to multi-cylinder internal combustion engines with fuel injection, both conventional internal combustion engines with an intake manifold injection and direct-injection internal combustion engines of a more modern design.
- an intake pipe of the internal combustion engine is used
- the fuel is injected directly into the combustion chambers of the internal combustion engine at different times during an operating cycle.
- Direct-injection internal combustion engines can be operated in different operating modes. There is a shift operation, which is used in particular for smaller loads, and a homogeneous operation with larger loads applied to the internal combustion engine. Further operating modes are, for example, an operating mode for heating an exhaust gas catalytic converter, an operating mode for desulfurization of an exhaust gas catalytic converter or for nitrogen oxide (NOx) regeneration of an exhaust gas catalytic converter.
- an operating mode for heating an exhaust gas catalytic converter an operating mode for desulfurization of an exhaust gas catalytic converter or for nitrogen oxide (NOx) regeneration of an exhaust gas catalytic converter.
- NOx nitrogen oxide
- fuel is injected into a combustion chamber during a compression phase in such a way that a fuel cloud is in the immediate vicinity of a spark plug at the time of ignition.
- This injection can take place in different ways. 'Thus, it is possible that the injected fuel cloud already during or immediately after the injection is located in the spark plug and is ignited by this. It is also possible that the injected fuel cloud is guided to the spark plug by a charge movement and only then ignited. In both combustion processes there is no uniform distribution of fuel, but a stratified charge.
- the advantage of the shift operation is to / that there with a very small quantity of fuel adjacent the lower loads of the internal combustion engine can be performed. However, larger loads cannot be met by shift operation.
- homogeneous operation corresponds approximately to the mode of operation of conventional internal combustion engines with intake manifold injection. If necessary, homogeneous operation can also be used for smaller loads.
- stratified operation the throttle valve in the intake pipe leading to the combustion chamber is opened wide and the combustion is essentially only controlled and / or regulated by the fuel mass to be injected.
- the throttle valve is opened or closed depending on the requested torque and the fuel mass to be injected is controlled and / or regulated depending on the air mass drawn in.
- the fuel mass to be injected is additionally controlled and / or regulated as a function of a plurality of further operating variables to an optimum value with regard to fuel savings, exhaust gas reduction and the like.
- the control and / or regulation is different in both operating modes.
- the present invention is based on the object of avoiding torque jumps during the operation of an internal combustion engine in a specific operating state, for example when switching off cylinders or when changing the operating mode.
- the invention proposes, starting from the method of the type mentioned at the outset, that the filling of the combustion chambers with fuel and air or with a fuel / air mixture is individually controlled or regulated for each combustion chamber.
- the different fillings can relate to the amount of fuel or air or to the composition of the fuel / air mixture with which the individual combustion chambers of the internal combustion engine are filled.
- the filling of the combustion chambers can be controlled or regulated, for example, via electromechanically or electrohydraulically controlled inlet or starter valves or via the injection valves.
- torque jumps such as when switching off individual ones Cylinder of an internal combustion engine or when changing the operating mode of a direct-injection internal combustion engine occur, can be avoided by a suitable control or regulation of the filling of the individual combustion chambers.
- any number of cylinders can be switched off depending on the operating state of the internal combustion engine. It would even be conceivable to selectively switch on or off each individual cylinder of an internal combustion engine depending on the load present.
- Torque jumps when switching off one or more cylinders or when changing the operating mode of the internal combustion engine can be prevented.
- the method according to the invention leads to a reduction in fuel consumption, particularly in stationary operation.
- the filling of the combustion chambers with fuel and air or with a fuel / air mixture be determined individually for each combustion chamber.
- the filling of the combustion chambers can be regulated to a predefinable setpoint.
- the filling be measured by a filling sensor that is specific to the combustion chamber.
- a combustion chamber pressure sensor for example, can be used as the filling sensor.
- the output signal of the charge sensor represents the actual charge in the combustion chamber.
- the filling be modeled from a torque that is recorded individually for the combustion chamber. Either the actual torque or a target torque can be recorded. Using a torque model, the cylinder-specific filling of the individual combustion chambers can be modeled from the actual torque as well as from the target torque. In a reciprocal application and calculated individually for each cylinder, the number of cylinders that have to be operated with a homogeneous mixture can be calculated from the torque model in order to achieve the required target torque. The remaining cylinders remain in the most economical shift operation.
