Method for introducing pre-compressed combustion air into a combustion chamber of an internal combustion engine, a high-pressure inlet valve therefor and an internal combustion engine having such a high-pressure inlet valve

摘要

A method for introducing combustion air into a cylinder 25 of an internal combustion engine, a high-pressure inlet valve 1 provided for this purpose, and an internal combustion engine operated using this method and the high-pressure inlet valve will be described. All combustion air to each of the cylinders 25 is drawn from the internal combustion engine on the basis of a controlled mass flow through the high pressure inlet valve 1 disposed in the associated cylinder head 26 so that mixture formation and charge exchange are enhanced. introduced into the cylinder 25 . In addition, the temperature and/or pressure of the combustion air is measured and the amount of combustion air is controlled with the high-pressure inlet valve 1 by opening and closing the sliding piston 3 of the high-pressure inlet valve 1 by displacement. is introduced into the cylinder 25 based on the measurement result. As a result of the axial displacement of the sliding piston 3 between the guide sections 5 of the housing 2 of the high-pressure inlet valve 1 , the passage region 6 for combustion air is in the closed position 7 . shut off and open in the open position (8). In the passage region 6 , the sliding piston 3 has two pressure application regions 10 , 11 opposing each other, the surfaces of which are equal or different in size in the case of protrusions into one plane. The first pressure application region 10 can be designed as a poppet valve 12 , and the second pressure application region 11 can be designed as an annular surface 13 . The internal combustion engine has a high-pressure line 27 for combustion air, which is connected to a high-pressure inlet valve 1 . With respect to the longitudinal axis of the cylinder 25 , the high-pressure inlet valve 1 is arranged in the cylinder head 26 in a standing or horizontal position.
