AI Technical Summary
Technical Problem
The supercharged gas engine has poor responsiveness during load burst time, resulting in large speed drops and long recovery time, limiting its use in high-load applications.
Method used
When the load suddenly increases, the amount of mixed gas entering the cylinder is increased according to the engine speed reduction ratio, and the air or mixed gas is replenished in front or after the mixer to help restore the engine speed.
Benefits of technology
It effectively improves the instantaneous power and speed recovery capability of the engine during load sudden overflow, shortens the speed recovery time, and improves loading performance.

Abstract
The invention relates to the technical field of internal combustion engines, in particular to a method for improving the loading performance of a supercharged gas engine, the gas engine and application. The gas engine is provided with a gas supplementing pipeline, and when the rotating speed reduction ratio of the gas engine is larger than a set limit value and the rotating speed reduction rate is larger than a set rotating speed reduction rate limit value, the gas supplementing pipeline is started; the amount of mixed gas entering the cylinder is increased. The amount of mixed gas entering the air cylinder is supplemented and increased according to the change condition of rotating speed reduction of the gas engine, and the rotating speed recovery capacity of the engine is improved. According to the method, when the load is suddenly increased, the gas homogeneous with the gas pressurized by the gas compressor is automatically supplemented into the pipeline behind the gas compressor of the supercharger, the gas compressor of the supercharger does not need to be pressurized, the load of the gas compressor of the supercharger is reduced, and the working efficiency of the gas compressor during loading is improved; meanwhile, the gas enters an engine cylinder to participate in acting, the engine power is increased, the instantaneous power of the engine is additionally increased, the speed of a supercharger is increased, and the rotating speed recovery time is shortened.
