摘要:
A method for operating a hybrid vehicle and a hybrid vehicle are disclosed. The hybrid vehicle includes a supercharged internal combustion engine having an overboost function and at least one electric drive. An overboost phase of the supercharger of the internal combustion engine is followed by a regeneration phase of the supercharger and a corresponding drop in torque, wherein the at least one electric drive is used to at least partially compensate for the drop in torque of the internal combustion engine during the overboost regeneration phase of the supercharger. Thus, an improved driving behavior with an extended overboost phase can be achieved.
摘要:
A method for operating an internal combustion engine is disclosed, in which method test injections are carried out in order to adapt, during the operation of the internal combustion engine, the injection parameters used for the control of the injection processes. For this purpose, during the test injections, an electric machine which is coupled to the internal combustion engine generates negative torque impulses in a manner synchronized with the positive torque impulses generated by the test injections, which negative torque impulses counteract the torque impulses generated by the test injections. In this way, rotational speed oscillations generated by the test injections are eliminated. Also described is an internal combustion engine of said type.

An engine control system comprises a first control device which is associated with a first section of the cylinders, and a second control device which is associated with a second section of the cylinders. The first control device is designed in order to determine an intermediate required value (TQI_INT_SP_FAST) for a torque to be set quickly which is set by way of one or more final control elements for setting a quantity of fuel that is to be metered or an ignition angle. The intermediate required value (TQI_INT_SP_FAST) is determined depending on at least one operating variable of the internal combustion engine. The first control device is also designed in order to determine at least one correction value for the torque to be set quickly [lacuna] at least one operating variable. The first control device has a communications interface for communicating the intermediate required value (TQI_INT_SP_FAST) and the at least one correction value to a communications interface of the second control device. The second control device is designed in order to determine a required value (TQI_FAST2) of a fast torque to be set depending on the intermediate required value (TQI_INT_SP_FAST), the at least one correction value and at least one measured variable associated with the second control device, and in order to set the required value (TQI_FAST2).

摘要:
An engine-controlling unit/method for an internal-combustion engine with first and second combustion-chamber groups having a first and second catalytic exhaust-gas converter, respectively, having (a) a master control device that controls a combustion-air ratio for the first combustion-chamber group by forcibly exciting the first combustion-chamber group, further having (b) a slave control device that controls a combustion-air ratio for the second combustion-chamber group by forcibly exciting the second combustion-chamber group, and further having (c) a data link between the master and slave for control through the master. It is proposed (d) for the master to transmit a synchronizing signal to the slave over the data link during changeover between the rich and lean combustion-air ratio within the scope of forced excitation, and (e) on receipt of the synchronizing signal from the master for the slave to change over within the scope of forced excitation between the rich and lean combustion-air ratio.

An internal combustion engine has an air intake tract which comprises at least one inlet pipe leading to one intake duct per cylinder of the internal combustion engine. It also has at least one exhaust gas duct per cylinder of the internal combustion engine, at least a first actuator which is disposed in an inlet pipe or in an intake duct or in an exhaust gas duct and influences the gas exchange in the respective cylinder.
摘要:
An internal combustion engine has a plurality of cylinders having combustion chambers and each being associated with a spark plug designed for igniting a mixture of air and fuel in the combustion chamber, and at least two adjusting devices for adjusting the air supply to the combustion chambers of the different cylinders. To control the internal combustion engine, an individual ignition angle is detected for each group of cylinders to which the same air mass per working cycle is respectively supplied and during the respective working cycles of which the same loss torque is decisive. The decisive loss torque is the one associated with the cylinder that is in its intake cycle during the respective working cycle of the respective cylinder of the respective group. The individual ignition angle for each group is detected as a function of the decisive loss torque for the respective group.
