Problems solved by technology

[0006] 1. The elasticity of the pressure regulating spring exists at a certain constant value, which cannot change with the load of the engine working condition. It is difficult to control the elasticity of the pressure regulating spring, and it is difficult to meet the working requirements of the engine. Therefore, the pressure regulating spring still has great development and improvement Although the gas spring can meet the needs of the engine, it is difficult to develop practically due to the connection structure and operation mode of the piston;
[0007] 2. There is a lack of positioning pin grooves between the inner and outer pistons. In order to form specific air convection in the combustion chamber and the arrangement of the intake and exhaust valves in some engines, the top surface of the piston often requires a corresponding shape. Therefore, for the corresponding For the engine, it is necessary to consider setting up corresponding pin grooves between the inner and outer pistons to solve this problem;
[0009] 4. Before the combined pressure regulating piston, due to the emphasis on the adjustment and control of pressure and temperature, the thermal efficiency of the engine was not significantly improved during the working process, and it relied heavily on the improvement of the compression ratio and the adoption of emerging technologies.

Abstract

The invention discloses a combined pressure regulating piston based on an elastic silencing and impact-resistant cylinder gasket and relates to the combined pressure regulating piston. The elastic silencing and impact-resistant cylinder gasket is arranged between a cylinder cover and a cylinder body and consists of an upper sealing gasket, a cylinder gasket main body and a lower sealing gasket which are connected in sequence; the cylinder gasket main body comprises an elastic steel plate, circular holes, elastic steel claws, mounting holes and water channel holes; the circular holes are formed in the middle of the elastic steel plate; the elastic steel claws are uniformly and symmetrically arranged at the periphery of each circular hole; the mounting holes and the water channel holes are formed outside the circular holes. The combined pressure regulating piston highly affects the heat efficiency of the torque of an engine, the heat efficiency of a gasoline engine can be improved by about 7 percent, and the heat efficiency of a diesel engine can be improved by about 5 percent; under the condition that the elastic force of a pressure regulating spring can be regulated, all the advantages of the combined pressure regulating piston can be played at the same time, and playing of the roles of external additional mechanisms of the engine such as a turbo charging mechanism and a stratified combustion mechanism is not affected.
