摘要： The invention relates to a method for combustion misfire detection in multi-cylinder internal combustion engines. In the method, rough-running values for each cylinder of the engine are determined individually for each crankshaft rotation by measuring the segment times. The segment times include the times corresponding to the piston movement of each cylinder to be measured during which times the crankshaft passes through a corresponding circular segment angular region and, on the basis of filtered rough-running values, equalization or corrective factors are computed for each cylinder in an evaluation unit for influencing injection times or injection time points of each individual cylinder. The determined rough-running values (LUT) or the filtered rough-running values (FLUT) are compared in a desired value comparison to a threshold value (SW2) which is pregiven in value significantly less than the threshold value (SW1) for misfire detection. A reduction of the threshold value (SW1) for misfire detection to a lower level is effected by the continuous dropping below the second threshold value (SW2) within a pregiven time interval (&Dgr;t) or during a specific number of engine revolutions (&Dgr;u).

摘要： The invention concerns a method to determine the composition of a fuel from the components ethanol and gasoline of an internal combustion engine, wherein the fuel is supplied to the internal combustion engine by a fuel supply unit and via two fuel distributor rails; and the exhaust gas is discharged from the internal combustion engine by two exhaust gas manifolds of a first and a second exhaust gas system, which are separated from each other, wherein the first and second exhaust gas system have in each case at least one exhaust gas probe and wherein current changes in the ethanol content of the fuel are evaluated from the signal differences of lambda signals from the exhaust gas probes. With this method, a change in the ethanol content of the fuel can be detected, and an explicit condition for a change in fuel can be derived. Moreover, with the method, errors in the fuel-mixture can be distinguished from an altered fuel composition, which takes place after the tank has been filled fueling.

摘要： The invention is directed to a method and arrangement for checking the operability of a vessel. Pressure is introduced into the vessel utilizing a pressure source having operating variables which vary during operation of the pressure source. These operating variables are detected while the pressure is introduced into the vessel and a conclusion as to a presence of a leak in the vessel is drawn from the operating variables. By utilizing the operating variables, a statement as precise as possible is provided as to the presence of the leak with as little additional equipment as possible.

摘要： The operation of an internal combustion engine under unfavorable operating conditions can lead to the formation of deposits in the combustion chamber (4). A method and an arrangement for operating an internal combustion engine (1), especially of a motor vehicle, is suggested, wherein fuel is conducted into a combustion chamber (4) and is there combusted. When deposits are detected in the combustion chamber (4), measures are initiated in a targeted manner for cleansing the combustion chamber (4). A knocking combustion is especially introduced and/or a cleansing liquid is added to the inducted combustion air.
