摘要:
The invention is directed to an internal combustion engine, especially for a motor vehicle. The engine has a combustion chamber into which fuel can be injected in at least two operating modes. A control apparatus is provided with which a switchover between the operating modes can be effected. A desired value (rlmd$s) can be determined with the control apparatus for the air charge in the combustion chamber. The desired value (rlmd$s) defines a maximum value for the air charge in the combustion chamber which is not exceeded.

An internal combustion engine (1), especially of a motor vehicle, is described. The engine (1) is provided with a combustion chamber (4) into which fuel can be injected in a first operating mode during a compression phase and in a second operating mode during an induction phase. The engine (1) is provided with a control apparatus (18) for switching over between the operating modes. The engine (1) includes an exhaust-gas recirculation having an exhaust-gas recirculation valve (14). The engine (1) is switched by the control apparatus (18) into the first operating mode when the exhaust-gas recirculation valve (14) is jammed in the open state.

An internal combustion engine, especially for a motor vehicle, is described which is provided with a combustion chamber into which fuel can be injected in at least two operating modes. A control apparatus is provided with which a switchover can be made between the operating modes in dependence upon a desired operating mode. With the control apparatus, an operating-mode request can be determined in dependence upon whether the individual operating modes are in the position to generate the requested torque while maintaining pregiven lambda limits.
摘要:
The method for controlling operation of a vehicle having at least two possible operating modes includes calculating and/or determining the operating variables and/or control variables of at least one active one of at least two possible operating modes in a first continually repeated predetermined time interval and calculating and/or determining the operating variables and/or control variables of at least one inactive one of the at least two possible operating modes in at least one other continually repeated predetermined time interval. The first predetermined time interval is shorter than any of the one or more other predetermined time interval(s). A device for performing the method is also described.
摘要:
A method for adjusting the torque in an internal combustion engine is introduced having the steps: determining a desired torque; determining an operating point from measured values for air charge and rpm; determining a standard torque for this operating point; determining a desired efficiency from standard torque and desired torque; determining the lambda corresponding to this efficiency; determining the fuel quantity from the corresponding lambda and the air charge derived from measurement quantities. The fuel quantity in combination with the air charge yields the corresponding lambda for realizing the desired torque.
摘要:
An internal combustion engine is provided with an injection valve with which fuel can be injected directly into a combustion chamber either during a compression phase in a first operating mode or during an intake phase in a second operating mode. In addition, a control unit is provided for shifting between the two operating modes and for differentiated control and/or regulation of the performance quantities that influence the actual torque of the internal combustion engine as a function of a setpoint torque in both operating modes. A change in the actual torque during a shifting operation is determined by the control unit, and at least one of the performance quantities is influenced by the control unit as a function thereof.
摘要:
An internal combustion engine, in particular for a motor vehicle, is described. The internal combustion engine is equipped with an injection valve with which fuel can be injected directly into a combustion chamber either, in a first operating mode, during a compression phase or, in a second operating mode, during an intake phase. Also provided is a control device for switching between the two operating modes and for differing open-loop and/or closed-loop control, in the two operating modes, of the operating variables influencing the actual torque of the internal combustion engine as a function of a reference torque. A change in the actual torque during a switchover is operation is detected by the control device and as a function thereof, at least one of the operating variables is influenced by the control device.
