[Class 7 (ii)] Two superposed ports, in the cylinder wall of a two-stroke engine, uncovered in succession by the piston, lead to helical passages 1, 2 formed round a tubular core D. High-pressure exhaust gas, flowing down the passage 1 escapes from a chamber 3 through nozzlelike passages formed by vanes 3<1> and withdraws lower pressure exhaust gas from the passage 2 into a chamber E. Further gas issues through perforations 3<11>. The chamber E is surrounded by rings 5 having cylindrical chambers 8 into which the gas enters by tangential passages 6, and from which it escapes by passages 9 leading to annular chambers 10 having exit slots 11 like those described in Specification 456,063, [Group XXXIII].

366,257. Exhaust silencers. BLANCHARD, J., 416, Elizabeth Street, Sydney, Australia. Jan. 16, 1931, No. 1507. [Class 7 (ii).] Exhaust gases enter a conical chamber 1, lined with soundproof material 2 such as asbestos by a pipe 5 and leave by a pipe 16. The gases are caused to gyrate by an inclined sector plate 8, the curved edge of which makes contact with the inner surface of the chamber, and the plane of which is arranged at an angle to an axial plane of the silencer. After flowing round and contacting with the rear face of the sector plate, the gyrating action is accentuated.

The present invention relates to a vortex generator installed in an intake pipe or an exhaust pipe of an internal combustion engine to increase a flow rate of air. The vortex generator for an internal combustion engine comprises: an outer pipe member having the outer circumferential surface closely fixed to the inner circumferential surface of the intake pipe or the exhaust pipe, and formed in a cylindrical shape; an inner pipe member disposed inside the outer pipe member, formed in a cylindrical shape, and having an outer vortex forming space at the outside and an inner vortex forming space at the inside to be separated from each other; a plurality of outer vortex forming wings for allowing a flow of air passing through the outer vortex forming space to form a vortex by being disposed radially between the outer pipe member and the inner pipe member and for fixing the inner pipe member to the inside of the outer pipe member by being fixed to the outer pipe member and the inner pipe member at both ends; and a plurality of inner vortex forming wings for allowing a flow of air passing through the inner vortex forming space to form a vortex in the same direction as the direction of the vortex formed by the outer vortex forming wings by being disposed radially from the center to the edge at the inner side of the inner pipe member. According to the present invention, vortices are respectively formed from each of the spaces divided in a concentric form by the outer pipe member and the inner pipe member. Therefore, the rotational speed of the vortex can be increased while minimizing the resistance to the air flow in the intake pipe or the exhaust pipe, thereby increasing the inflow or outflow of air.
