Method for optimizing a valve-lift changeover on spark-ignition engines |
摘要 |
This invention describes a method for optimizing a valve-lift changeover on spark-ignition engines with lambda control. On the basis of the evaluation of an acceleration characteristic and a lambda characteristic during the valve-lift changeover, it is determined whether cylinder charging errors and/or torque errors that require correction are present in the spark-ignition engine.
