  • Patent number: 7885757
    Abstract: There is provided a dither control means that performs a dither control, which compulsively changes an air-fuel ratio alternately to rich side and to lean side by increasing and decreasing fuel injection quantity of an injector (fuel injection valve) in a stepped manner. A predicted value (ideal A/F value ID), which indicates an ideal change of a detection value of an A/F sensor (oxygen concentration sensor) in a case where the A/F sensor is not degraded, is set as a standard value. Then, an integral of a difference between the detection value of the A/F sensor, which changes in accordance with the dither control, and the standard value is calculated. If a calculated value of the integral is larger than a predetermined value, it is determined that the A/F sensor is degraded.

  • Publication number: 20100269805
    Abstract: A switching element is connected between a heater of an oxygen sensor and a ground in series. A voltage sensing resistor is connected in parallel with the switching element and in series with the heater. When the switching element is in a de-energization state, if the heater degrades and a resistance of the heater changes, a heater terminal voltage (potential at middle point between heater and voltage sensing resistor) changes correspondingly. Therefore, when the switching element is in the de-energization state, a heater terminal voltage determination parameter changing in accordance with the heater terminal voltage is sensed, and a degradation determination value corresponding to a battery voltage and temperature of the heater is calculated from a map. The heater terminal voltage determination parameter is compared with the degradation determination value to determine whether the heater has degraded.

  • Patent number: 7677227
    Abstract: An opening of a waste gate vale is adjusted to control an actual supercharging pressure of intake air. Abnormality in a changing characteristic of the actual supercharging pressure relative to a change in a TCV control duty value can be detected. When an engine is in a steady operation condition, the TCV control duty value is forcibly changed repeatedly by a predetermined amount from 0% to 100%. A deviation between a target supercharging pressure corresponding to the TCV control duty value and an actual supercharging pressure is calculated each time the TCV control duty value is changed by the predetermined amount. This deviation is compared with an abnormality determination value to determine presence/absence of the abnormality in the changing characteristic of the actual supercharging pressure relative to the change in the TCV control duty value.

  • Patent number: 7380448
    Abstract: A malfunction detection apparatus is disclosed for a forced induction system. The system includes a compressor provided on an upstream side of a throttle valve in an intake passage of an engine, an upstream intake pressure sensor that detects intake pressure between the compressor and the throttle valve, and an atmospheric pressure sensor that detects atmospheric pressure. The malfunction detection apparatus includes a malfunction detection program that makes a comparison between the atmospheric pressure detected by the atmospheric pressure sensor and the upstream intake pressure detected by the upstream intake pressure sensor. The comparison is made in an operating state of the forced induction system in which the compressor compresses an amount of air that is approximately equal to or less than a predetermined amount to thereby determine whether the upstream pressure sensor has a malfunction.
