Title: Secondary air supplying device for internal-combustion engine
Inventor: KOSUDA TOORU
IPC: F01N3/34
Filed: 1982-04-01
Abstract: PURPOSE:To facilitate the following of a reed-type non-return valve to a pressure fluctuation even in the high-speed, high-load operating conditions of the engine by a method wherein the volume of the reed-type non-return valve downstream chamber is made as small as possible and an expansion chamber of a small volume is provided near the reed-type non-return valve downstream chamber at the downstream side thereof. CONSTITUTION:When the pressure of the reed valve downstream chamber 9 is positive, the reed-type non-return valve 6 is closed. On the other hand, when the pressure of the same 9 is negative, the reed-type non-return valve is opened and the secondary air is introduced into the reed valve downstream chamber 9 from a reed valve upstream chamber 10. The high-frequency side of the pressure of exhaust gas pulsation is damped by the expansion chamber 13 provided near the reed valve downstream chamber 9 at the downstream side thereof while the low-frequency side thereof is not damped substantially, therefore, the pressure fluctuation delivered to the reed valve downstream chamber 9 is slowed down and the following of the reed-type non-return valve 6 to the pressure fluctuation becomes easier. The acute portions of the negative pressure are decreased at the same time and, therefore, a reverse flow through the valve may be prevented.
