EVAPORATIVE EMISSION CANISTER PURGE ACTUATION MONITORING SYSTEM |
摘要 |
<p>An evaporative emission canister purge actuation monitoring system includes an integrated valve body having a main flow passage, a first one-way umbrella valve mounted to the valve body that is responsive to predetermined positive pressure in the main flow passage to control flow of fluid from a vapor canister to ambient air as well as a second one-way umbrella valve that is responsive to a predetermined negative pressure in the main flow passage to control the flow of ambient air through a fresh air port. A vacuum actuated switch is supported by the integrated valve body and in electrical communication with a control unit. The switch is responsive to negative pressure in the main flow passage to send a signal indicative of the predetermined negative pressure to the control unit.</p> |
