An electromagnetic fuel injection valve in which an area of an annular gap formed by a ball valve and a valve seat when the ball valve is lifted is made smaller than cross sectional area of grooves provided on a fuel swirling element which gives fuel supplied a swirling force and further is made larger than a cross sectional area of a fuel injection port, whereby the fuel is injected with an excellent atomizing characteristic.

A two-flow-passage type exhaust gas driven turbocharger, in which a scroll portion in a casing is divided by an annular partition to form two flow passages, the turbo-charger being constructed so that the difference between the temperature of the outer surface of the portion of the casing to which the partition is fixed and that of the partition can be minimized so as to reduce the thermal strain in the partition and thereby prevent thermal fatigue cracks from occurring therein.
