Method for improving fuel utilization efficiency of internal combustion engine and air exhausting type internal combustion engine

Abstract

The invention discloses a method for improving the fuel utilization efficiency of an internal combustion engine and an air exhausting type internal combustion engine. The method comprises the following steps: when certain air cylinder of the internal combustion engine is in the work doing stroke, a part of combustion hot gas in the combustion chamber of the air cylinder is conveyed into the air cylinder, wherein the air cylinder is in the later period of the compression stroke of the internal combustion engine, the combustion hot gas of the air cylinder is inputted to ignite the fuel in the air cylinder in the later period of the compression stroke, the air cylinder is enabled to enter the work doing stroke with higher initial pressure and initial combustion temperature, during the workingdoing stroke entering process of the air cylinder, a part of combustion hot gas in the combustion chamber of the air cylinder is conveyed into the air cylinder, and the air cylinder is in the later period of other compression strokes of the internal combustion engine. The invention aims to provide the method for improving the fuel utilization efficiency of the internal combustion engine and the air exhausting type internal combustion engine, and the method and the air exhausting type internal combustion engine have the following benefits: the fuel utilization efficiency can be greatly improved, the energy consumption is reduced, combustion is enabled to be more homogeneous and is adapted to higher air-fuel ratio, the selective range of the air-fuel ratio is larger, and the emission load of various pollutants harmful to the environment is greatly reduced.

Description

technical field [0001] The invention relates to a method for improving the fuel utilization efficiency of an internal combustion engine and an air-pumping internal combustion engine. Background technique [0002] During the power stroke process of the cylinder of the existing internal combustion engine, due to failure to adjust the initial pressure and initial combustion temperature to a better state, and the speed of ignition is not ideal, resulting in low fuel utilization efficiency and low fuel consumption. Larger, the discharge of various pollutants harmful to the environment is also larger. Contents of the invention [0003] The purpose of the present invention is to provide a fuel utilization efficiency that can greatly improve, reduce energy consumption, make the combustion more homogeneous, can adapt to a higher air-fuel ratio, make the optional range of the air-fuel ratio larger, and can be greatly improved. A method for improving the fuel utilization efficiency ...
