A New Method of Investigation of Swirl Ports 770404

A NEW METHOD is described for determinating swirl in internal combustion engines, which is based on the direct measurement of the angular momentum of the cylinder-charge. A corresponding swirl-parameter is defined and its relation to conventional swirl-parameters is discussed.Engine-tests prove this swirl-parameter to be the flow-characteristic which controls the combustion in Diesel-engines with direct injection. The optimum adjusting of swirl to a combustion system by means of a cylinder head with flexible inlet ports and the cylinder head with two swirl producing inlet ports are discussed as examples. They show that the new method is advantageous for theoretical and practical reasons.
