  • Method and arrangement for diagnosing the open-loop control of the tank-venting valve in combination with the open-loop control of an internal combustion engine
    Patent number: 5243853
    Abstract: A method is introduced of checking the drivability of a tank-venting valve (TEV) and of an idle actuator.After actuating the TEV, an additional air/fuel mixture is supplied to the intake region of an internal combustion engine having an air/fuel ratio which can be equal to that at which the engine usually operates (.lambda..sub.0) or greater or less than .lambda..sub.0. Reactions of a .lambda.-control and/or of an idle control can be evaluated in dependence thereon. It is advantageous that a check is made independently of how intense the additional air/fuel mixture is enriched with fuel.
