Title: Exhaust gas purifier for engine
Inventor: KAGEYAMA GENGO
IPC: F01N3/34
Filed: 1978-03-02
Abstract: PURPOSE: To raise the durability and reduce noises, by opening a stop valve installed in a negative pressure inlet passage, as occasion demands, to stop or limit the secondary air supply.  
     CONSTITUTION: When the stop valve is opened, the intake negative pressure at the downstream side of a throttle valve 6 is introduced into a secondary air feed passage 9 between an air cleaner 2 and a check valve 10 through an orifice 14 so that a reed valve 10a of the check valve 10 is not opened and closed or the open/close motion of the reed valve is restricted. Even when the negative pressure of exhaust pulsation acts on the downstream side of the check valve 10, the pressure at the upstream side of the check valve is kept negative by the introduction of the intake negative pressure. Thus, the open/close motion of the reed valve 10a is stopped or restricted. This results in substantially stopping or restricting the introduction of the secondary air.
