  • Patent number: 10961607
    Abstract: A hardfacing alloy satisfies the following condition when the hardfacing alloy as a whole is 100 mass % (also simply referred to as “%,” hereinafter), Ni: 10-25%, Si: 1-3%, Fe: 3-18%, the total of one or more elements of Mo, W, and Nb: 6.5-20%, and the balance: Cu and impurities. In particular, it preferably satisfies Fe+2Mo?22.6(%), Mo equivalent/Fe?1.17, and Mo equivalent=Mo+0.522W+1.033Nb. In a hardfacing part composed of the hardfacing alloy, coarse hard particles are formed to ensure the wear resistance, and a soft phase present in the hard particles ensures the machinability. This may be understood as a raw material powder for hardfacing treatment and may also be understood as a hardfacing member in which a hardfacing part is formed on a base material using the raw material powder.

  • Patent number: 10961946
    Abstract: An engine system includes a combustion chamber including a cylinder, a fuel supply that supplies fuel including gasoline into the combustion chamber, circuitry configured to predict a knock will occur in the combustion chamber, and a fluid injector that injects a fluid into the combustion chamber. Further, there is circuitry configured to suppress a knock by instructing the fluid injector, when the knock is predicted to occur by the circuitry configured to predict, to inject the fluid into the combustion chamber within a period before a burned mass fraction reaches 50% after a start of combustion.

  • Patent number: 10871112
    Abstract: A method and system for predicting the occurrence of a knock which will have a predetermined intensity or higher (intense knock) in an engine that burns an air-fuel mixture of gasoline fuel. The pressure in a combustion chamber is detected during an initial stage of combustion. This pressure is compared with a preset reference value to determine whether or not the cylinder inner pressure exceeds the reference value during the combustion. When the cylinder inner pressure exceeds the reference value, it is predicted that the intense knock will occur before an end of the combustion. If the intense knock is predicted, additional fuel or other material can be injected into the combustion chamber to prevent the occurrence of the intense knock.

    Abstract: A vehicle information transmission system that carries out communication with a management server that manages a vehicle includes an electronic control unit. The electronic control unit is configured to acquire vehicle information in accordance with a third sampling pattern that is a combination of a first sampling pattern and a second sampling pattern. The vehicle information is transferred within an in-vehicle network installed in the vehicle. The first sampling pattern is a sampling pattern in which the vehicle information is sampled at a change point at which a predetermined change has occurred. The second sampling pattern is a sampling pattern in which the vehicle information is sampled at intervals of a predetermined period. The electronic control unit is configured to transmit the acquired vehicle information to the management server.

  • Publication number: 20200362540
    Abstract: A work vehicle is provided. The work vehicle is capable of notifying an operator of a state close to overheating of a temperature of a cooling oil that cools a brake device before the temperature overheats. A controller (10) in a work vehicle (100) compares each detection value detected from a brake pressure sensor (26) and a vehicle speed sensor (15) to each threshold (V1, P1, R1) predetermined corresponding to each sensor. The controller (10) outputs a warning command that a temperature of a cooling oil is likely to overheat to a notification device (28) when a state that at least one detection value is equal to or more than the threshold and when a state that at least one detection value is equal to or more than the threshold continues for a first duration (t1) or more.
