  • Publication number: 20260126024
    Abstract: An air intake system having a turbocharger and an intercooler provides combustion air for an internal combustion engine of an all-terrain vehicle. The all-terrain vehicle includes a straddle seat, and the he intercooler is mounted above the internal combustion engine. The intercooler has a plurality of pressurized air crosspipes defining an intercooler plane. An intercooler attack angle of the intercooler plane relative to horizontal is greater than or equal to 80° and less than 90°. The air intake system includes an intake pressure relief system with a pressure sensor and a pressure relief valve. When the pressure sensor senses an onset of an overpressure event, the pressure relief valve is opened. The turbocharger housing is integrally formed with the exhaust manifold, and the exhaust manifold has flange gaps between exhaust intake ports, which allow thermal expansion difference between the cylinder head and the exhaust manifold.

  • Publication number: 20250042810
    Abstract: A microwave heat treatment method for granulated blast furnace slag is provided, which includes the following steps: subjecting the granulated blast furnace slag to microwave heat treatment at a frequency of 900-930 MHz and then cooling the slag. Microwave rapid heating is utilized to remove the moisture in the granulated blast furnace slag, stress is generated inside the granulated blast furnace slag particles to promote the formation of cracks or the decomposition of the granulated slag particles into small particles. After the microwave reaches a certain power, the microwave is turned off, an air blower is turned on, and thermal stress is generated inside the granulated blast furnace slag particles, so that the particles are further promoted to generate cracks or fragmentation; and then the desired fine powder can be obtained by ball milling the granulated blast furnace slag after microwave heat treatment for a short time.

  • Patent number: 11638069
    Abstract: Techniques are described for using computing devices to perform automated operations to control acquisition of images in a defined area, including obtaining and using data from one or more hardware sensors on a mobile device that is acquiring the images, analyzing the sensor data (e.g., in a real-time manner) to determine the geometric orientation of the mobile device in three-dimensional (3D) space, and using that determined orientation to control the acquisition of further images by the mobile device. In some situations, the determined orientation information may be used in part to automatically generate and display a corresponding GUI (graphical user interface) that is overlaid on and augments displayed images of the environment surrounding the mobile device during the image acquisition process, so as to control the mobile device's geometric orientation in 3D space.
