Device for producing turbulence of sucked in charge in internal combustion engine, particularly compression ignition engine

摘要

The device has a suction valve (5) arranged in the suction channel (3)whose stem (6) is formed at least in the portion adjacent to the plate (7)one helical groove (10). This spiral groove (10)passes to the plate (7) and ends before the abutment surface (8) toseclla (9) suction valve (5). Part of the stem (6) of the intake valve (5)on which a helical groove (10) is formed with a maximumthe intake valve opening (5) is completely in the suction channel (3), Vcross-section, the helical groove (10) has a circular shapeor the V-shape, or the V-shaped shape of the V-shapedspiral grooves (10) may be more than one, theirthe diameter of the suction valve stem (6) is limited.
