Problems solved by technology
When the engine equipped with a turbocharger is running at high speed and high power, the total compression ratio is high and knocking is likely to occur. When the engine is running at low speed and low power, the compression ratio is low and the engine efficiency is low.
A small number of engines with adjustable compression ratios are basically not put into use due to complex structures, high manufacturing costs, increased engine weight, poor performance of the combustion chamber or unfavorable emissions, and are only used as research or demonstration prototypes.
In addition, since the end-of-compression temperature of existing internal combustion engines is basically uncontrollable, it is difficult to increase the compression ratio due to the impact of knocking, making it difficult to improve the fuel efficiency of the engine

Description
technical field [0001] The invention relates to a compression mode, an expansion work mode and a combustion heating mode of an internal combustion engine. Background technique [0002] The intake air distribution method and combustion heating method of the internal combustion engine are usually that the air enters the cylinder directly through the intake valve, and is compressed in the cylinder to complete the intake air distribution process. At the same time, fuel is supplied during the intake process or compression process, and ignited and heated , to complete the combustion heating process. The compression and expansion work of the gas is performed in the same cylinder, and the compression ratio and expansion ratio of the engine cannot be adjusted. And during the combustion heating process, the volume of the combustion chamber changes, and constant volume heating cannot be realized. If there is a turbocharging device, the air is pressurized by the turbocharging device a...
