This utility model discloses an air supply structure for an air-assisted injection system, including a structural body mounted on the cylinder head. The structural body includes a premixing chamber, an air supply pipe, and a check valve. The premixing chamber is located inside the structural body. The air supply pipe is mounted on the structural body and communicates with the premixing chamber. The check valve is located in the channel between the premixing chamber and the air supply pipe. When the air pressure in the air supply pipe reaches the opening pressure of the check valve, the check valve opens, and air enters the premixing chamber through the check valve. The air-fuel mixture in the premixing chamber cannot enter the air supply pipe through the check valve. This air supply structure of the air-assisted injection system effectively prevents the backflow of the air-fuel mixture in the premixing chamber into the air supply pipe and air pump by adding a check valve between the air supply pipe and the premixing chamber, thus avoiding the problem of reduced fuel injected into the cylinder and the impact on engine performance and fuel consumption.

This application provides a device-level intelligent rendering optimization method, system, medium, and device applied to the Windows operating system graphics rendering workflow: An interception component deployed between the Windows graphics API and the GPU driver captures the application rendering data stream; an analysis component uses AI to identify redundant data, divides the screen area, and generates a report; an optimization component accordingly performs redundant data deletion, rendering call merging, data compression, and rendering pipeline reconstruction; an output component encapsulates the optimized data and transmits it to the GPU for rendering; and a feedback component collects GPU status data and dynamically adjusts the analysis strategy. The optimization process does not modify application code and ensures visual effects are consistent with the original data. This application's solution achieves global rendering optimization through device-level intervention, reducing GPU resource consumption and enabling low-end GPUs to smoothly run high-quality rendering scenes. Simultaneously, AI analysis balances performance and image quality, reducing hardware upgrade costs for users.
