    • 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.
    • 使用气流计测量进气量随着EGR阀强制变化时的实际进气量。 基于所测量的实际进气量和柴油发动机的燃料喷射量来估计柴油发动机中的燃烧后废气的氧浓度。 将估计的氧浓度与用A / F传感器感测的实际氧浓度进行比较,从而感测A / F传感器的响应。 即使用于使EGR阀进入空气量变化的响应时间变化,响应时间的变化也不影响氧气浓度的估计,因为根据实际进气量来估计氧气浓度。 因此,可以高精度地感测A / F传感器的响应。
