摘要： The present invention provides a system and method for controlling the retard limit of an engine having one or more cylinders in which combustion occurs. A sensor is employed to detect the ionization of the combustion process in the cylinders. The ionization is related to a retard limit feedback, and the sensor further transmits a signal associated with the retard limit feedback. A controller relates the retard limit feedback signal to a metric, monitors the stochastic behavior of the metric, and adjusts the ignition timing of the engine in response to the stochastic behavior to operate the engine below a retard limit target.

摘要： A circuit for measuring ionization current in a combustion chamber of an internal combustion engine including an ignition coil, having a primary winding and a secondary winding, and an ignition plug. The ignition plug ignites an air/fuel mixture in the combustion chamber and produces an ignition current in response to ignition voltage from the ignition coil. A capacitor, charged by the ignition coil, provides a bias voltage producing an ionization current after ignition of the air/fuel mixture in the combustion chamber. A current mirror circuit produces an isolated current signal proportional to the ionization current. In the present invention, the ignition current and the ionization current flow in the same direction through the secondary winding of the ignition coil. The charged capacitor operates as a power source and, thus, the ignition current flows from the charged capacitor through the current mirror circuit and the ignition coil to the ignition plug.
