IPC: B63B43/18
Filed: 2021-02-26
Abstract: To provide a navigation avoidance support device capable of automatically deriving an optimum navigation avoidance operation method corresponding to steering performance of a ship.SOLUTION: A preference degree calculation section 24 calculates a preference degree expressing subjective preference of a ship operator associated with selection of respective positions for each position of a navigation avoidance operation space (space where a choice of a veering angle is combined with a choice of a speed change ratio). A danger degree calculation section 26a assumes a state of an own ship after a predetermined time from a present point of time by reflecting a steering performance parameter expressing steering performance of the own ship, and calculates a degree of collision danger with respect to another ship in a case where the own ship performs a navigation avoidance operation under the state for each position of a navigation avoidance performance space. A utility value calculation section 20 calculates a utility value by subtracting a degree of collision danger from the preference degree for each position of the navigation avoidance operation space. An operation instruction section 23 instructs an operation method of the own ship so as to meet a route in a case where the navigation avoidance operation based on a calculation result of the utility value calculation section 20 is performed under a state after a predetermined time.SELECTED DRAWING: Figure 1

Title: Intake manifold for engine
Inventor: ADACHI YUKIKO
IPC: F02M35/10
Filed: 2021-03-17
Abstract: To provide an intake manifold having an excellent processing function for water included in EGR gas.SOLUTION: An intake branch passage 18 of an intake manifold 5 includes an upward part 24, a peak part 25, and a downward inclination part 26, the downward inclination part 26 consisting of a twin passage part 26a on the downstream side partitioned by a partition wall 27, and a single passage part 26b on the upstream side of the partition wall 27. An EGR gas outlet 33 is opened toward a site closer to the peak part 25 than the partition wall 27, out of the single passage part 26b. Even when condensed water is generated in an EGR distribution passage 32, the condensed water is atomized riding on intake air without staying in a surge tank 14 and then scattered into the downstream, and so no trouble occurs. Since the EGR gas outlet 33 is offset to be closer to the peak part 25, the dispersibility of EGR gas from the intake air is improved to make EGR gas concentration in one of two intake ports 28 equal to that in the other.SELECTED DRAWING: Figure 4
