Definitions
- the invention relates to a method for feeding a medium combustible in an internal combustion engine, in particular a cryogenic medium, such as hydrogen, into an internal combustion engine.
- the gaseous hydrogen is advantageously injected into the closed cylinder only just before the top dead center of the piston.
- the temperature of the intake air at top dead center is approx. 275 ° C. If cold hydrogen is now injected into the combustion chamber of the cylinder, the compression temperature is lowered and the compression work is thus destroyed.
- the object of the present invention is to provide a generic method for feeding a medium, in particular a cryogenic medium, into an internal combustion engine which avoids the aforementioned disadvantages
- a generic method is proposed, which is characterized in that the medium is heated before it is fed into the internal combustion engine at least to ambient temperature, preferably to a temperature of at least 500 ° C, and the internal combustion engine with a pressure between 100 and 500 bar , preferably at a pressure between 200 and 300 bar.
- the level of the temperature to which the medium supplied to the internal combustion engine is heated is also determined by whether the air / medium mixture which arises in the combustion chamber of the cylinder is spark-ignited or ignites itself.
- the temperature to which the medium supplied to the internal combustion engine is heated cannot be high enough.
- the upper temperature limit is determined in individual cases according to the type of medium and the energy available for heating the medium.
- the required injection pressure of 100 and 500 bar can be built up comparatively efficiently in the hydrogen storage container in the liquid phase, in particular when using liquid hydrogen as fuel.
- the medium is heated before being fed into the internal combustion engine at least partially by heat exchange with the or one of the exhaust gas streams of the internal combustion engine.
- Alternative or additional procedures are conceivable for the aforementioned embodiment of the method according to the invention, such as, for example, electrical heating, heating by burning part of the medium, etc. These alternative or additional procedures are expediently predominantly used during the starting phase of the internal combustion engine.
- the method according to the invention for feeding a medium into an internal combustion engine enables the efficiency of an internal combustion engine to be increased up to approx. 50%; the respective increase in efficiency depends on the selected compression ratio and the selected injection pressure.
- gaseous fuels such as natural gas or GH
- gaseous fuels such as natural gas or GH
