<p>Air-stirring blade for producing an agitating effect within an internal combustion engine has been disclosed in PCT/IB99/00029. The turbulency performed by the velocity of the air-fuel mixture leaving the outltet part of this device however is still low enough. The air-stirring blade of this invention comprises a cylindrical body (1) whose mid portion is provided with blade (2) of such a construction that the inner side of the blade (2a) takes the form of stirred grooves with dip angle (3) of about 10° to 80° or typically 30° with respect to vertical axis of the body. The outer side of the blade (2b) is of the same shape with the inner side (2a) thereof and there are four tangent lines (4) between blade (2) and body (1) forming a channel of cap-shaped cross-section (5) which is twisted along body (1). The preferred embodiments of this air-stirring blade as some related modifications as well.</p> |
