Method for diagnosing errors in an intake system of an internal combustion engine having a variable intake manifold geometry |
摘要 |
A method for diagnosing errors in an intake system of an internal combustion engine having a variable intake manifold geometry is provided. According to the method, an air mass flow oscillation in the intake manifold is detected at an engine rotational speed that is present, the detected air mass flow oscillation is subjected to signal analysis to determine a characteristic actual oscillation variable which is compared to a setpoint oscillation variable associated with the engine rotational speed that is present.
