Embodiment Construction

[0029] Table 1: Different pressures and temperatures during the adiabatic compression of air, and the boiling temperature of water at these pressures. The reference for calculating the lower value of adiabatic compression as well as information on the boiling point of water and the necessary pressurization comes from the book Energiteknik by Henrik Alvarez, Studentlitteratur i Lund, 1990.

[0030] Table 1 shows that there is an intersection point marked in bold at approximately 4.5 bar. At lower pressures, the boiling temperature of water is higher than that of compressed air, while at the same time, the boost required to prevent water from boiling is lower than the pressure of compressed air. At pressures above 4.5 bar, the boiling temperature of water is lower than that of compressed air, while at the same time, the boost required to prevent water from boiling is higher than the pressure of compressed air. This is the basis of the inventive concept. During spraying, t...

Abstract

A method of compressing a medium in the combustion chamber of a combustion engine, by which method a liquid, in the state of a spray, is introduced into the compression chamber during a compression stroke, the liquid is pressurized and heated before it is introduced into the compression chamber to such a degree that at least a part of the droplets of the spray explode spontaneously upon entrance in the compression chamber, the liquid being pressurized to such an extent that, at the moment of introduction, it has a steam pressure that is above the pressure that, at the moment of introduction, exists in the compression chamber, and the liquid being heated to such an extent that, at the moment of introduction, it has a temperature that exceeds the boiling point of the liquid for the temperature and the pressure that, at the moment of introduction, exists in the compression chamber, and the heat being water. The liquid is heated to such an extent that, at the moment of introduction, it has a temperature that is below the temperature of the medium at the moment of introduction of the liquid.

Description

technical field [0001] The invention relates to a method for compressing a medium in a combustion chamber of an internal combustion engine, by which liquid in the injected state is introduced into the compression chamber during the compression stroke, and the liquid is pressurized and heated to to the extent that at least a portion of the sprayed droplet spontaneously bursts upon entry into the compression chamber, the liquid is pressurized to such an extent that it has a vapor pressure higher than that present in the compression chamber at the time of introduction, and the liquid is Heated to such an extent that, at the time of introduction, it has a temperature exceeding the boiling point of the liquid at the temperature and pressure present in the compression chamber at the time of introduction, and the liquid is water. [0002] The invention also relates to a method for compressing a medium in a combustion chamber of an internal combustion engine, by means of which a liqui...
