A method for the diagnosis of leakages according to the ventilation through flow - control stop

摘要

A steam venting system for a motor includes a vent valve with a housing, the one input terminal in connection with a deaeration tank, and the one exhaust port in connection with an intake system component, which contains a first bore portion, which defines the outlet port with a first sealing element arranged between them receives. The intake system component contains a second bore section, the one housing section of the vent valve with a second sealing element arranged between them receives. The first and second sealing elements, are spaced apart so that, when the housing of the intake system component is pulled away and the first seal between the first bore and the outlet port is released, the second sealing element can remain in engagement, so that a diagnostic module the solution of the vent valve can be diagnosed by the intake system, before hydrocarbon vapor into the atmosphere can be released.
