摘要： There is described a method for detecting the ambient pressure by means of a pressure sensor in the intake pipe of an internal combustion engine. A throttle flap is opened so that the pressure drop via the throttle flap can be neglected. The dethrottling of the internal combustion engine is compensated by the appropriate adjustment of the cam shaft in accordance with the operating state of the internal combustion engine, so that the measuring method is not being felt by the driver.

摘要： The method for determining an air mass in a cylinder of an internal combustion engine with a supercharging device and with a device for variably controlling the valve overlap of the gas exchange valves is characterized by a reference characteristic curve for the air mass inside the cylinder that, according to the operating conditions, defines a linear correlation between the air mass inside the cylinder and the pressure inside the induction pipe, and when the induction pipe pressure exceeds the exhaust counter pressure, the value of the air mass from the reference characteristic curve is corrected with a value for the supercharging rate that is defined as the characteristic curve according to the operating conditions above the pressure inside the induction duct.

摘要： An internal combustion engine has a fuel delivering device with a high-pressure pump which conveys fuel into a fuel reservoir, and a volume flow control valve that is assigned to the high-pressure pump. A control difference (FUP_DIF) is determined from a difference between a predefined fuel pressure (FUP_SP) and a detected fuel pressure (FUP_AV). The control difference (FUP_DIF) is fed to a controller that encompasses at least one integral portion (I_CTRL). A corrective value (COR) for an error value of a fuel flow rate is determined in accordance with the integral portion (I_CTRL) of the controller if a sum of the integral portion (I_CTRL) exceeds a given threshold value during a predefined mode of operation of the internal combustion engine. In addition, an actuating signal (PWM) for the volume flow control valve is generated according to a controller value (FUEL_MASS_FB_CTRL) and the corrective value (COR).

摘要： A method is disclosed for checking a valve on an exhaust gas turbocharger of an internal combustion engine, wherein an exhaust gas flow exits the internal combustion engine, a first portion of said flow flowing through a turbine of the exhaust gas turbocharger into an exhaust gas system and a second portion flowing through the valve into the exhaust gas system, wherein said method includes the steps of varying a fuel-to-air ratio in a fresh gas supplied to the internal combustion engine, determining a residual oxygen content in the exhaust gas system, and determining that the valve is defective if a variation of the residual oxygen content occurs in a manner different than a predetermined manner of the variation of the fuel-to-air ratio in the fresh gas. A device for checking the valve can be integrated into an integrated engine control unit of the internal combustion engine.

摘要： In order to diagnose a coolant pump (11) which is provided for the purpose of circulating a coolant in a closed cooling circuit of an internal combustion engine (10) and which can be activated and deactivated independently of the operating state of the internal combustion engine (10), both a value representing the coolant temperature (TCO) of the internal combustion engine (10) and a value representing the cylinder head temperature (TZK) of the internal combustion engine (10) are determined at a predefined time instant (t2) after a cold start of the internal combustion engine (10) has been detected and the values are subsequently compared with each other. The coolant pump (11) is rated in terms of its operational integrity as a function of the result of the comparison. This enables a faulty coolant pump to be detected at a very early stage after a cold start of the internal combustion engine.
