ABSTRACT:
A device for generating vortex in cooling water for cylinders of internal combustion engines is disclosed. In the device, a steel casing is inserted into the bottom portion of a cooling water passage of a cylinder head. The steel casing is comprised of inner and outer rings, with an annular cavity being formed between the two rings and allowing engine oil to pass through. A plurality of pressure units are radially mounted to the inner ring. Each of the pressure units is radially movable in opposite directions in response to the pressure of the engine oil in the annular cavity, thus forming vortex in the cooling water passing through the inner ring. The device of this invention enlarges the cooling water contact area of the cylinder, thereby improving the cylinder cooling effect and increasing the engine output power.
