Abstract
An internal combustion engine with an air intake system for transmitting combustion air to at least one cylinder chamber is involved which consists of one or more intake pipes (1-4) coiled more than 180.degree. and of means for controlled variation of the effective intake pipe length as well as at least one throttle mechanism whose movement can be controlled, where the means for varying the intake pipe length and the throttle mechanism for controlling the air volume are combined structurally in a substantially cylindrical, rotary slide valve (17) which can be rotated in a controlled manner about a cylinder axis (18) and also in a controlled manner can be moved to a limited degree in the direction of the cylinder axis (18).
Claims7
An intake system for an internal combustion engine comprising an intake pipe having an intake fitting, a coil loop and an end piece, said coil loop having a radius such that said intake fitting and said end piece cross, said intake system further comprising a cylindrical rotary slide valve perpendicular to the plane of said coil loop and disposed in said intake pipe at said location at which said intake fitting and said end piece cross, said cylindrical rotary slide valve operable to vary the length of said intake pipe and to vary the cross section of said intake pipe through axial displacement and through rotation of said valve.
An intake system for an internal combustion engine comprising an intake pipe having an intake fitting, a coil loop and an end piece, said coil loop having a radius such that said intake fitting and said end piece cross, said intake system further comprising a cylindrical rotary slide valve disposed in said intake pipe at said location at which said intake fitting and said end piece cross, said cylindrical rotary slide valve operable to vary the length of said intake pipe through axial displacement of said valve and to vary the cross section of said intake pipe through rotation of said valve to thereby throttle air volume through said intake.
