摘要： In an internal combustion engine with exhaust gas turbochargers which operate in parallel and of which at least one can be switched on and off by a charge air duct blocking arrangement including a charge air duct blocking element, the charge air duct blocking arrangement is adapted to provide for a certain movement characteristic of the charge air duct blocking element resulting in a slower movement of the charge air duct blocking element resulting in a longer duration for the air duct blocking element to reach its open position and a faster movement during closing resulting in a rapid closing of the charge air duct blocking element.

摘要： A method and a control device for monitoring the pressure in a crankcase of an internal combustion engine. The desired values for the pressure in the crankcase are defined for a plurality of operating points of the internal combustion engine. Furthermore, at least one of the defined desired pressure values is modified during operation of the internal combustion engine.

摘要： A method for improving the cold start capacity of an internal combustion engine which is cooled with water that is pre-heated for the cold start. The pre-heated hot water is conducted through flow paths in a region of the crankcase ventilating device and/or in a water/air heat exchanger of the crankcase ventilating device. An internal combustion engine with at least one cooling water circuit, at least one cooling water pump which is arranged in the cooling water circuit, and at least one crankcase ventilating device. The crankcase ventilating device is at least temporarily integrated into the cooling water circuit of the internal combustion engine, and the cooling water circuit has a pre-heating assembly for pre-heating the cooling water when the internal combustion engine is cold started.

摘要： An emission signature modification device for modifying an acoustic signature of an exhaust gas stream, including an exhaust gas guiding device that guides the exhaust gas stream in the flow direction thereof from an inlet area to an outlet area. An active acoustic emission modification device modifies the acoustic emission of the exhaust gas stream in predetermined operating states. If an actuator system of the active acoustic emission modification device is designed such that in a circumferential direction, the actuator system is surrounded by more than 30% of the guided exhaust gas stream, the actuating system can be protected against harmful influences from the environment by way of the exhaust gas guiding device on the one hand, and on the other hand, the required space signifier can be reduced as compared to a lateral, external arrangement of the actuating system.

摘要： An internal combustion engine including a cylinder head, a fresh air duct configured for providing a fresh air supply to the internal combustion engine, and a quick-closing valve arranged in the fresh air duct, upstream of the cylinder head of the internal combustion engine, in order to interrupt the fresh air supply. The internal combustion engine also includes an exhaust gas recirculation pipe that has an outlet opening that is arranged centrally in the fresh air duct and, in a flow direction of the fresh air supply, upstream of the quick-closing valve forming a minimum gap between the outlet opening and the quick-closing valve.

摘要： A method for correcting a fuel quantity injected by a fuel injection device during operation of an internal combustion engine, including: determining an air heat characteristic variable, on which an air heat stream fed to a combustion chamber of the engine functionally depends; determining an exhaust heat characteristic variable, on which an exhaust heat stream discharged from the combustion chamber functionally depends; determining a heat distribution factor, which specifies a fraction of the exhaust heat stream reduced by the air heat stream in relation to a heat stream fed with the injected fuel to the combustion chamber; calculating a fuel mass fed to the engine from the air heat characteristic variable, the exhaust heat characteristic variable and the heat distribution factor; calculating a comparison variable by comparing the calculated fuel mass with a fuel mass setpoint value and adapting actuation of the fuel injection device depending on the comparison variable.

摘要： A method and an assembly for controlling the pressure in a high-pressure region of an injection system in an internal combustion engine. A set high pressure is compared to an actual high pressure in order to determine a control deviation, the control deviation representing an input variable of a controller. A high pressure pump is controlled by a solenoid valve and the angle at which the delivery of fuel by the at least one high-pressure pump is to start is used as a manipulated variable of the high-pressure closed-loop control system.

摘要： A supercharging unit for an internal combustion engine has a high-pressure turbine which drives a high-pressure compressor so as to perform a rotational movement about a first axis and through which exhaust gas of the internal combustion engine flows, and having a low-pressure turbine which drives a low-pressure compressor so as to perform a rotational movement about a second axis and through which exhaust gas flows. The high-pressure turbine is arranged rotationally conjointly on a first shaft, and the high-pressure compressor is arranged rotationally conjointly on a second shaft, wherein the first and the second shaft are arranged parallel to one another and are arranged offset with respect to one another, wherein the first and the second shaft are mechanically operatively connected to one another such that the high-pressure compressor can be driven by the high-pressure turbine.
