  • Patent number: 11326543
    Abstract: The invention is provided with 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 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 an injector to inject fuel at such timing that the fuel exists in a cylinder at an earlier time point than the preceding ignition. Timing of the preceding ignition is more advanced when a swirl flow is gentle than when the swirl flow is strong.

  • Publication number: 20220131609
    Abstract: To relax the accuracy with respect to a deviation with respect to an optical axis or an angular deviation, and thus to reduce costs. An optical waveguide is included that performs propagation only in a reference mode at a first wavelength. Communication is performed using light of a second wavelength that enables the optical waveguide to perform propagation in at least a first order mode in addition to the reference mode. When light entering the optical waveguide deviates with respect to an optical axis or deviates angularly, propagation is performed in at least the first order mode in addition to the reference mode, the first order mode being generated due to the deviation with respect to the optical axis or the angular deviation. This results in a reduction in a loss of coupling of optical power. This makes it possible to relax the accuracy with respect to a deviation with respect to an optical axis or an angular deviation, and thus to reduce costs.

Also, when the partial compression ignition combustion is carried out, the injection control section causes an injector to inject fuel at such timing that the fuel exists in a cylinder at an earlier time point than the preceding ignition. Timing of the preceding ignition is set to be more retarded when an engine speed is high than when the engine speed is low.

  • Publication number: 20220035111
    Abstract: The coupling loss of optical power on a reception side due to an axis deviation on a transmission side is satisfactorily mitigated. A connector body including an optical path adjusting unit and a lens is provided. The optical path adjusting unit adjusts an optical path such that the diameter of incident light is reduced while the incident angle is kept. The lens collects light whose optical path has been adjusted, and causes the light to be incident on a light receiver. For example, light incident on the optical path adjusting unit is collimated light. Furthermore, for example, the optical path adjusting unit has a through hole in a central portion. While the incident angle of light to the light receiver satisfies an NA, the focal distance of the lens is decreased. This can mitigate the coupling loss of optical power on a reception side due to an axis deviation on a transmission side.

  • Publication number: 20220026648
    Abstract: The coupling loss of optical power on a reception side due to an axis deviation on a transmission side is satisfactorily mitigated. A connector body including a first lens and a second lens is provided. The first lens converges light emitted from a light-emitting body. The second lens shapes and emits the light converged by the first lens. For example, the second lens shapes light emitted from the first lens into collimated light. The focal distance of the second lens can be increased while increase in the distance from the light-emitting body to the second lens is inhibited and the diameter of light from the light-emitting body is restricted so as to be within the diameter of the second lens. The coupling loss of optical power on the reception side due to the axis deviation on the transmission side can be mitigated.
