An air conveying system, especially in the air intake system, for a reciprocable piston internal combustion engine having at least one group of cylinders and valve seats respectively associated therewith which valve seats have an opening toward the cylinders, according to which a plurality of tap lines respectively connected to the cylinders of the group of cylinders lead to the pertaining valve seat openings and communicate with a collecting conduit which is common to all of the tap lines pertaining to one and the same group of cylinders while having at least approximately the same length. Twist forming means are respectively arranged within the range of the valve seat openings for imparting a twist upon the air masses to be passed through the valve seat openings. The cross section of the tap lines and of the respective common collecting conduit pertaining thereto increase gradually in a steady manner from the pertaining valve seat openings in the direction away therefrom. The distance between the respective valve seat openings and the remote end of the pertaining common collecting conduit is at least approximately the same.
An air intake system for a reciprocable piston internal combustion engine having at least one group of cylinders with valve seats opening into the respective cylinders, said system including a conduit having an air inlet end, a plurality of tap lines opening from the other end and connected to the cylinders of said group and opening into the respective valve seat openings, the end of each tap line opening into said conduit having a diameter substantially equal to the diameter of the conduit at that end, each of said tap lines having a curved end connecting to its respective valve seat opening as a twist forming means arranged adjacent the respective valve seat opening for imparting a twist to the air passing through said valve seat opening, the cross section of said conduit and the said tap lines opening therefrom decreasing gradually in a continuous manner from the inlet end of said conduit to the opening for each tap line and continuing such gradually decreasing area to the respective valve seat opening of each tap line, the distance from the inlet end of said conduit to the end of each tap line opening into its respective valve seat opening being substantially equal, so that on each inlet stroke of each piston, the same volume of air is delivered to the cylinder and the decreasing area of said conduit and each tap line increases the velocity of the air passing from said inlet end of said conduit to said twist forming means and the respective valve opening.
