摘要： The aerosol diluting apparatus includes

a first diluting unit to provide a first modified sample flow by combining an aerosol sample flow with a first diluting gas flow,
an ejector unit to draw the first modified sample flow from the first diluting unit to the ejector unit and to provide a second modified sample flow by mixing a second dilution gas flow with the first modified sample flow,
a control unit, and
a control valve,
wherein the control unit and the control valve are arranged to adjust flow rate of the second dilution gas flow according to an inlet pressure of the aerosol sample flow, so as to keep the dilution factor of the diluting apparatus substantially independent of the inlet pressure.

摘要： Methods and systems are provided for diagnostics of a cylinder valve actuation mechanism in a variable displacement engine (VDE). In one example, during an engine-off condition, the engine may be rotated unfueled, via a starter motor, and a reference exhaust air flow may be estimated. One or more deactivatable engine cylinders may then be deactivated and degradation of the cylinder valve actuation mechanism may be indicated based on a difference between the exhaust air flow following the cylinder deactivation and the reference exhaust air flow.

摘要： A method for diagnosing a measurement of a pressure difference. The measurement is carried out with a measuring arrangement for a component of an exhaust gas device, the input of which is connected to a first exhaust gas pipe and the output of which is connected to a second exhaust gas. The measuring arrangement is provided with a pressure difference measuring device and with a first and second pressure measurement point, which are connected to the pressure difference measuring device for measuring the pressure difference between a pressure measured at the first pressure measurement point and at the second pressure measured at the second pressure measurement point. The pressure difference between the two pressure measurement points is measured with a pressure difference between measuring device.

摘要： Method for the operation of an internal combustion engine having a plurality of cylinders (11 to detect misfires. An exhaust gas sensor at the exhaust gas of every cylinder of the internal combustion engine measures at least one actual exhaust gas value individually for the respective cylinder, and the respective measured actual exhaust gas value is compared with a reference exhaust gas value to determine at least one cylinder-specific deviation between the reference exhaust gas value and the actual exhaust gas value for each of the cylinders. It is determined for every cylinder based on the cylinder-specific deviation or based on every cylinder-specific deviation whether or not misfires are occurring at the respective cylinder.

摘要： A sensor control apparatus which receives from a gas sensor (10) a sensor output signal Ip corresponding to the concentration of a specific gas component, and a pressure signal P output from a pressure sensor (20). The sensor control apparatus includes a computation section (38) which computes a specific component concentration which is corrected based on the pressure signal P so as to eliminate the influence of the pressure of the gas. The sensor control apparatus includes response adjustment sections (34) and (36) for adjusting the response rates of the sensor output signal Ip and the pressure signal P before being input to the computation section (38), the response rate exhibiting a time variation of the corresponding signal to a change in the pressure of the gas, such that the response rate of the sensor output signal Ip or the response rate of the pressure signal P, whichever is faster, approaches the slower of the two.

摘要： An on-board diagnostic for a particle filter of a vehicle exhaust system records repeating data about flow and pressure around the particle filter. Data is recorded in virtual data bins having successive thresholds or filters within a numerical scale. Each data point is typically recorded in several bins to permit a rapid calculation of averaged data for use in the diagnostic. Sensitivity of less frequently recorded data is preserved, whilst giving quickly delivery of a result from the diagnostic.

摘要： It is an object of the present invention to improve estimation accuracy of an air excess ratio within a fuel spray and quickly cause the air excess ratio to approximate to a target value when the engine load factor rises. An internal combustion engine control apparatus includes a parameter acquiring section to acquire an air intake parameter and a fuel parameter, a first estimation section to estimate an in-fuel-spray air excess ratio using the air intake parameter and fuel parameter, and a pressure calculation section to calculate, if the in-fuel-spray air excess ratio is less than a target in-fuel-spray air excess ratio, a necessary fuel injection pressure to match the in-fuel-spray air excess ratio with the target in-fuel-spray air excess ratio, in which if the necessary fuel injection pressure is equal to or less than a maximum injection pressure, fuel injection is to be performed at the necessary fuel injection pressure.
