  • Patent number: 10794249
    Abstract: An amount of deposition of intramural PM in a particulate filter is estimated with a high degree of accuracy. A controller obtains, as a correlation between a reference value of an intramural PM deposition amount and an oxygen storage capacity of the catalyst, a change over time of an oxygen storage capacity of the catalyst according to a change of a filter PM deposition amount in a period of time from a point in time at which the filter PM deposition amount is substantially zero to a point in time at which the oxygen storage capacity of the catalyst, which becomes larger according to an increase of the filter PM deposition amount, reaches a maximum value. Further, the controller estimates a current intramural PM deposition amount based on a current oxygen storage capacity of the catalyst and the correlation.

  • Publication number: 20200264074
    Abstract: A state detection system for an internal combustion engine is provided. A detection mapping takes, as inputs, rotation waveform variables and a road surface state variable to output a combustion state variable. The rotation waveform variables include information on a difference between cylinders in the rotational speed NE of a crankshaft during periods in which the respective cylinders generate combustion torque. The combustion state variable relates to a level of variations in combustion state among the cylinders. A determination process performed by an execution device determines whether the internal combustion engine is in a predetermined operating state based on an output value of the detection mapping that takes, as inputs, values of the rotation waveform variables and a value of the road surface state variable.

    Abstract: A state detection system for an internal combustion engine is provided. Rotation waveform variables include information on a difference between cylinders in the rotational speed of a crankshaft during periods in which the respective cylinders generate combustion torque. An obtainment process obtains a value of the rotation waveform variables and a value of a road surface state variable based on an output of a sensor that detects a state of the road surface. A selection process selects, from a plurality of types of mapping data stored in the storage device, the mapping data that is associated with the road surface state variable as the detection mapping. A determination process determines whether the engine is in a predetermined operating state based on an output value of the selected detection mapping that takes the rotation waveform variables as inputs.
