摘要:
The invention relates to a regulating method for a turbocharger (1) with a turbine (4) which has a variable turbine geometry (VTG) provided with adjustable guide blades (5), having the following method steps: a) closing the guide blades (5) of the variable turbine geometry (VTG), as a function of the present operating point of the internal combustion engine which is turbocharged by means of the turbocharged (1), to the maximum possible closing position of the guide blades (5) for said operating point, and b) regulating the charge pressure (P2) by adjusting the position of the guide blades (5) in a closed regulating loop.
摘要:
The invention relates to a method for regulating or controlling the compressor (2) of an exhaust gas turbocharger (3) of an internal combustion engine (4), having the following method steps: measuring an ambient air pressure (PU); measuring a static pressure (PV) upstream of the engine inlet; measuring the rotational speed (U) of the exhaust gas turbocharger (3); determining a static pressure (PE) which is present directly at the compressor inlet (11) by calculating a vacuum (Pdyn) in the compressor inlet line (11) and subtracting the calculated vacuum (Pdyn) from the measured ambient air pressure (PU); determining a static pressure (PA) which is present directly at the compressor outlet (12) by calculating the pressure loss (PDV) in the compressor outlet line (18) and adding the calculated pressure loss (PDV-) to the measured static pressure (PV); and regulating or controlling the compressor operation corresponding to at least one of the determined pressure values (PE or PA) and the rotational speed signal (SU).
摘要:
A graphical user interface (GUI) for presenting representations of selected objects in a computer system. The GUI presents an object selected from a collection of objects using a selected visual representation selected from at least first and second visual representations to be initiated using different initiation techniques. A first input control causes the selected object to be presented using another visual representation instead of the selected visual representation. A second input control causes another object to be presented instead of the selected object using any visual configuration that is currently used in presenting the selected object. The first and second input controls may be located in an object header area that remains essentially unchanged when changing between the at least first and second visual representations.
