Control of the spray pattern by the orifice which is not the angle of skew which was formed on the fuel injection metrical disk which possesses pouch volume decrease expedient and rises

摘要

The fuel injector which possesses the housing, the seat, the metrical disk and the closed component. As for the metrical orifice it is possible to arrange with respect to the 1st hypothetical circle whose 2nd it is demarcated by the projection of the sealing up surface which is focused in projection hypothetical apex on the metrical disk is larger than hypothetical circle. To rise in order to increase spray angle it is possible the metrical disk. Conical size of desire and it is possible making use of various parameters to obtain spray angle. Also the method of controlling on-target hit to the target of the spray of the fuel injector is stated.
