  • Publication number: 20210115839
    Abstract: An engine control apparatus includes an ignition control section and an injection control section. When partial compression ignition combustion is carried out, the ignition control section causes an ignition plug to carry out: main ignition in which a spark is generated in a late period of a compression stroke or an initial period of an expansion stroke to initiate the SI combustion; and preceding ignition in which the spark is generated at earlier timing than the main ignition. Also, when the partial compression ignition combustion is carried out, the injection control section causes the injector to inject fuel at such timing that the fuel exists in a cylinder at an earlier time point than the preceding ignition. Energy of the preceding ignition is set to be higher when an engine speed is high than when the engine speed is low.

  • Publication number: 20210080003
    Abstract: A transmission ratio controller includes circuitry. The circuitry includes a transmission ratio calculator configured to calculate a request transmission ratio to a transmission mechanism, a transmission ratio instructor configured to output a control signal based on the request transmission ratio, and an abnormality determiner configured to determine whether a transmission ratio of the transmission mechanism is abnormal. At least two of the request transmission ratio, an instruction transmission ratio corresponding to the control signal, or an actual transmission ratio achieved by the transmission mechanism are transmission ratios subject to comparison. The abnormality determiner is configured to determine that when a difference obtained by comparing the transmission ratios subject to comparison is greater than or equal to a predetermined specified value, the transmission ratio of the transmission mechanism is abnormal.

  • Publication number: 20210080002
    Abstract: A transmission ratio controller includes circuitry that includes a transmission ratio calculator calculating a request transmission ratio, a transmission ratio instructor transmitting a control signal, and an abnormality determiner. The request transmission ratio is calculated using a first transmission ratio map when a specified parameter satisfies a first condition, and a second transmission ratio map when the specified parameter satisfies a second condition. The internal combustion engine is in a first state when the specified parameter satisfies the first condition, and in a second state when the specified parameter satisfies the second condition. In the first state, the abnormality determiner calculates a hypothetical transmission ratio using the second transmission ratio map based on the second state.

  • Publication number: 20210027808
    Abstract: A heat-assisted magnetic recording (HAMR) head for recording data in data tracks of a HAMR disk has a gas-bearing slider that supports a near-field transducer (NFT) and a main magnetic pole formed of two layers. The first main pole layer has a cross-track width at the slider's gas-bearing surface (GBS) that tapers down in the direction towards the NFT where the optical spot is formed. The second main pole layer is located away from the NFT and has a substantially wider cross-track width than the first main pole layer so as to provide sufficient magnetic field for writing. Layers of heat sink material are located on the sloped cross-track sides of the tapered first main pole layer to reduce the temperature and thus the likelihood of oxidation of the main pole layers.
