PROCEDURE FOR CHECKING AND ADJUSTING THE EFFECT OF TURBULENCE CHANNELS IN MULTI-CYLINDER INTERNAL COMBUSTION ENGINES, ESPECIALLY IN DIRECT INJECTION MOTORS.

摘要

Procedure for checking the effect and adjustment of turbulence channels in standard cylinder heads of multi-cylinder internal combustion engines, especially in direct injection engines, in which a cylinder head with at least one cylinder head is assigned on the combustion chamber side a turbulence channel per cylinder a requested cylinder with depression, especially a simultaneous cylinder with a turbulence measurement device, and a respective turbulence coefficient per cylinder is assigned to the turbulent flows generated as a function of the flow rate through the turbulence channel and through an intake valve adjustable differently in its stroke, by comparing a turbulence coefficient calculated according to a formula from these turbulence coefficients referred to cylinders with a specific turbulence tolerance band of the engine, characterized in that depending on a turbulence coefficient outside the band of Turbulence tolerance is subsequently set correspondingly smaller or greater in its cross section the corresponding turbulence channel of the cylinder head in a segment of said channel.
