This invention relates to the field of engines, providing an engine intake air preheating method, system, device, and engine. The method includes: acquiring ambient temperature and atmospheric pressure values ​​after the engine is powered on; if the ambient temperature is less than 0 degrees Celsius, heating the air entering the engine through a heating rod, and injecting fuel onto the surface of the heating rod based on a pre-constructed MAP map; after starting the engine, acquiring the engine speed, and if the engine speed is higher than a first set speed, completing the engine intake air preheating. This invention addresses the shortcomings of existing diesel engines in cold starts at high altitudes, enabling the minimum intake air preheating power to adaptively adjust with engine speed, altitude, and ambient temperature during diesel engine startup. It supplements the deficiencies of existing design methods and improves the environmental adaptability of diesel engines.

The application provides a self-repairable EVA adhesive film and a preparation method thereof, and relates to the technical field of solar photovoltaic module packaging. The self-repairable EVA adhesive film realizes a double self-repairing mechanism of photovoltaic module packaging adhesive film through Diels-Alder reaction group grafting and silane coupling agent microencapsulation technology, and the double self-repairing mechanism includes physical rearrangement repair and chemical bonding repair. While maintaining high light transmittance (>= 90%) and bonding strength (>= 96 N / cm), the aging resistance (Delta YI <= 3) and service life of the EVA adhesive film are significantly improved, and the problems that the traditional EVA adhesive film is prone to aging and micro-damage caused by mechanical stress in extreme environments are solved. The preparation process of the application is compatible with the existing production line, and has high industrial application value.

This invention discloses a deformable metal curtain wall based on an adaptive mechanical structure, relating to the field of building curtain wall technology. Flexible rubber frames are installed on both sides of the metal curtain wall panel, and supporting thin steel plates are installed at equal intervals inside the flexible rubber frames. Connecting rubber strips are symmetrically connected to one end of each flexible rubber frame, and limiting rubber blocks are connected to one end of each connecting rubber strip. Assembly notches are symmetrically opened on both sides of the metal curtain wall panel, and clamping vertical plates are installed on the two inner walls of the back of the metal curtain wall panel. This invention utilizes the cooperation between the flexible rubber frames and the stacked supporting thin steel plates to provide a certain degree of offset deformation capability when the building sways and misaligns due to environmental factors such as earthquakes and strong winds. This prevents adjacent curtain wall panels from separating and falling off in the event of misalignment, giving the overall curtain wall a certain degree of environmental adaptability and making installation and use more stable.
