Method, computer program and control and/or regulating device for operating an internal combustion engine

Method and control apparatus for operating an internal combustion engine

Method and device for diagnosing a pop-off valve of a turbocharger

Method and device for providing air mass flow information in a supercharged internal combustion engine

Regulating position of hydraulic camshaft adjuster for internal combustion engine involves determining control parameters for PID regulator depending on hydraulic liquid state parameter(s)

Process and device to determine a secondary air mass in a combustion engine determines the pressure difference between two points of different cross section in the flow tube

Method for controlling combustion engine with combustion chamber, involves overflowing air mass from air intake system into waste gas system during valve overlap of gas shuttle valves

Internal combustion engine e.g. Otto engine, operating method for use in motor vehicle, involves determining characteristic value for suction output of cylinder in engine based on mass flow in suction pipe of engine

Compressor`s thrust circulating air-valve diagnosing method involves determining characteristic variable of signal of pressure sensor, comparing variable with predetermined value, and diagnosing function of valve based on comparison
