    摘要: An actual intake air quantity at the time when the intake air quantity is changed compulsorily with an EGR valve is measured with an airflow meter. An oxygen concentration of exhaust gas after combustion in a diesel engine is estimated based on the measured actual intake air quantity and a fuel injection quantity of the diesel engine. The estimated oxygen concentration is compared with an actual oxygen concentration sensed with an A/F sensor, thereby sensing response of the A/F sensor. Even if a response time for causing a change in the intake air quantity with the EGR valve changes, the change of the response time does not affect the estimate of the oxygen concentration since the oxygen concentration is estimated based on the actual intake air quantity. Therefore, the response of the A/F sensor can be sensed with high accuracy.

    摘要: In a transient state caused by fuel cut, a normal output of an A/F sensor having normal response and a lowered output having response lowered by a predetermined value as compared to the normal output are estimated, and an actual output of the A/F sensor is sensed. S1 as an integration value of a deviation between the normal output and the lowered output and S2 as an integration value of a deviation between the normal output and the actual output are calculated respectively until the normal output and the lowered output converge to an oxygen concentration equivalent to an atmosphere. S2 changes in accordance with a lowering degree of the response of the actual output. Therefore, the lowering degree of the response of the A/F sensor can be diagnosed based on S2/S1.

    摘要: A method for controlling air intake into an air conditioned enclosure includes generating a plurality of sensor output voltages using a NOx sensor. A NOx voltage ratio is calculated from the sensor output voltages. A determination is made when the NOx voltage ratio one of equals and exceeds a NOx threshold. The NOx voltage ratio is reset to a unitary value for a predetermined length of time.

    摘要: An injection quantity control apparatus for accurately performing an injection quantity learning process in a diesel engine creates an environment for obtaining a characteristic value in a one-to-one relationship with an actual injection quantity. A controller performs a one-shot injection operation for a cylinder of an engine while the environment is established. An injection command quantity is corrected based on an engine speed variation caused by the one-shot injection. After establishment of the condition and before the injection, the opening of a valve is controlled to be smaller than a reference and an opening of each of a diesel throttle and variable turbocharger is controlled to be larger than a reference. A composition of an air flowing into a combustion chamber is stabilized to ensure that the characteristic value detected after the one-shot injection is in a one-to-one relationship with the actual injection quantity.
