The present invention relates to a fuel valve assembly for controlling the injection of fuel into a combustion chamber of a two-stroke internal combustion engine, comprising a first valve part and a second valve part, where one of said valve parts comprises a portion at least partly surrounding a portion of the other valve part, wherein the one of said valve parts comprising a portion at least partly surrounding a portion of the other valve part has an outer face, the fuel valve assembly further comprising a hole extending from a first imaginary point of the outer face towards a second imaginary point of the outer face, intersecting the first valve part and the second valve part, and a fixation part arranged in the hole, engaging the first valve part and the second valve part and connecting the first valve part and the second valve part. The invention also relates to an internal combustion engine comprising a fuel valve assembly.

Provided is a method of producing an inorganic fiber mat, the method including: a preparing step of preparing a first inorganic fiber molding including an organic binder attached thereto and derived from a needle-punched mat; a defibrating step of defibrating the first inorganic fiber molding to obtain defibrated inorganic fibers; and a papermaking step of forming the inorganic fiber mat by papermaking using a slurry containing the defibrated inorganic fibers.

This utility model discloses an engine and its cylinder head gasket. The cylinder head gasket of this utility model includes a cylinder head gasket body, and a groove is provided on the upper surface of the cylinder head gasket body. Sealing parts are provided on both the inner and outer sides of the groove, respectively defined as an inner sealing part and an outer sealing part. The groove on the upper surface of the cylinder head gasket body reduces the area of ​​the upper surface, increases the surface pressure of the sealing surfaces of the inner and outer sealing parts, and reduces cylinder head gasket deformation caused by heat conduction. The cylinder head gasket of this utility model has good sealing performance and can effectively improve the sealing performance of the high-temperature and high-pressure combustion chamber of medium and large engines, ensuring the normal operation of the engine.

The utility model discloses a uniform powder coating device for the surface layer of a wire and cable insulation sheath, relates to the technical field of cable manufacturing, and aims to solve the technical problem that after a cable penetrates through talcum powder, isolation powder on the outer surface of the cable is instable in adhesion under zero pressure, the uniform powder coating device comprises a powder box with one side provided with a motor, and the interior of the powder box is connected with a material turning rod through the motor; and a material pushing pipe is arranged below the material turning rod. According to the talcum powder stirring device, the motor drives the stirring rod to rotate to stir enough talcum powder in the powder box, and meanwhile, the protruding strips further drive the clamping blocks to make contact with the clamping grooves in the outer surface of the control ring and control the material pushing pipe to rotate; in the rotating process of the pushing pipe, talcum powder is kept to be introduced into the pushing pipe through a communicating groove, and a tending force for moving towards the stabilizing pipe is applied to the talcum powder under the action of a pushing plate, so that part of the talcum powder is pressed by a trumpet-shaped extrusion pipe and is discharged along the other end of the stabilizing pipe; and the adhesion amount and adhesion stability of the powder on the surface of the cable are increased under the condition of increasing the pressure of the talcum powder on the surface of the cable.
