  • Patent number: 11530672
    Abstract: The present disclosure is intended to provide an internal combustion engine that can inhibit fuel from adhering to a piston and can reduce generation of soot. An internal combustion engine includes a piston, a cylinder accommodating the piston, and an injector including a nozzle that has a plurality of nozzle holes configured to inject fuel into the cylinder from above the cylinder. Among the plurality of nozzle holes, a sixth nozzle hole an axial direction of which is the most deflected toward the piston has a nozzle hole diameter larger than nozzle hole diameters of the other nozzle holes, and the nozzle hole diameter of the sixth nozzle hole corresponds to at least 20% of the total of the nozzle hole diameters of the other nozzle holes.

  • Patent number: 11398032
    Abstract: [Problem] To evaluate objective cell groups by estimating a mixing ratio of objective cell group without affecting treatment itself and its production process when the objective cell groups include plural kinds of cell groups having different attributes, and to provide an image analysis system and a culture management system capable of accurately perform a quality control and a production control with low cost. [Solution] The cell quality evaluation system 1 detects a feature amount in each cell easily analyzable from images, and estimates a mixing ratio of each of plural kinds of cell groups included in the objective cell groups based on a distribution of the detected feature amount and pre-recorded information of the feature amount. As the feature amount, the embodiment uses a migration speed of each cell, easily distinguishable by analyzing tracking of each cell from plural images in time series.
