摘要： A method for diagnosing a failure of a fuel pressure sensor for a high-pressure pump of a GDI engine includes a data collection step of collecting information on a state of a vehicle. A sensor condition determination step determines whether data collected in the data collection step meets conditions for determining the failure of the fuel pressure sensor. A failure determination step determines whether the fuel pressure value of the pressure sensor for the high-pressure pump is greater than or equal to a first reference value, and simultaneously, whether a fuel amount learning value is greater than or equal to a second reference value.

摘要： A method and apparatus for field testing and diagnosing at least one NOx-sensor in a diesel engine exhaust system are disclosed. The field testing apparatus is connectable to a truck having a lean burn diesel type engine, via an on-board diagnostic connector. The field testing apparatus is arranged to initiate a test cycle, and to diagnose at least one NOx-sensor in an exhaust system of the truck. The test cycle is performed on a running engine as a test sequence in a stationary truck, in at least two different states of operation, while NOx related values issued by the at least one NOx-sensor are measured over a predefined period of time. At least one state of operation is obtained by simultaneously opening the exhaust gas recirculation valve and controlling the back pressure valve for increasing backpressure. A dedicated algorithm is used to compare the measured values to a predefined model, and to provide a numerical summary and statistical evaluation of the sensor functioning. The numerical summary being indicative of a likelihood of the at least one NOx-sensor behaving correctly, and thereby enables a well founded decision as to whether or not the at least one NOx-sensor requires replacement.

摘要： A method and test device for recognizing detecting whether a mass air flow meter of intake air of an internal combustion engine is defective is provided. In the method and device, a test procedure is executed using a pilot controller while a mixture controller that is used in non-test engine operation is deactivated. The pilot controller for the mixture of fuel and air in the respective cylinders outputs control values which, during normal operation of the internal combustion engine via the mixture control, are varied on the basis of a mixture deviation of the current mixture from a stoichiometric mixture. The engine is set to one or more different idling speeds and at each respective idling speed the mixture deviation is detected. If the detected mixture deviation(s) (i'lA.) satisfy a predetermined criteria thresholds, the air flow meter is identified as defective.

摘要： An ECU executes a cylinder-by-cylinder air-fuel-ratio control in which an air-fuel-ratio of each cylinder is estimated based on a detection value of an air-fuel-ratio sensor to adjust the air-fuel-ratio of each cylinder. Further, the ECU computes a learning value of a correction quantity for each cylinder, which is obtained by executing the cylinder-by-cylinder air-fuel-ratio control. Then, the ECU determines whether the estimated air-fuel-ratio has converged according to whether the estimated air-fuel-ratio of each cylinder has been closer to a target value than a specified value for not less than a specified time period. A computation of the learning value is prohibited until the estimated air-fuel-ratio has converged. Therefore, it can be avoided to compute the learning value based on the fuel correction quantity that is obtained when the estimated air-fuel-ratio has not converged yet.
