摘要： A method for determining ignition angles for individual cylinders in a multicylinder internal combustion engine forms the ignition angles for the individual cylinders, based on values of a basic family of characteristics (KFB) which applies to all cylinders, as a function of a knocking behavior of the internal combustion engine on the basis of a first (fast) and second (slow) adaptation loop. Once the internal combustion engine has been stopped, the values that are present are used in a third adaptation loop to form a family of characteristics (KF3) which is applicable to all cylinders (z), and a shift value (ZW3(z)) for each cylinder. These are stored in a non-volatile manner.

摘要： An upper limit guard is set for a valve overlap amount according to a KCS learning value used to retard-correct an ignition timing in order to suppress knock, and an engine load. As a result, it is possible to make the upper limit guard value a value able to restrict the valve overlap amount to a value equal to, or less than, a value at which an internal EGR amount does not become excessive during a retard-correction of the ignition timing. By applying the upper limit guard to the valve overlap amount using the upper limit guard value, it is possible to suppress the valve overlap amount from increasing from the optimum value following a retard-correction of the ignition timing, as well as suppress the value of overlap amount from being reduced when it is not deviating from the optimum value and is below the upper limit guard value.

摘要： An apparatus and method to detect and control the combustion quality of a lean burn reciprocating engine using ionization signals is presented. The system receives a succession of ionization signals for successive cycles of a running engine and processes a plurality of related ionization signals for signal stability. A start point and peak of the ionization signal is identified, using an initial current level for all of the signals. A geometric parameter is associated with the ionization signal that relates the start point to the peak. The geometric parameter is compared against a reference geometric parameter related to a desired combustion quality relating to a lambda greater than 1.4. A control parameter of the engine is adjusted such that an error difference between the geometric parameter and the reference geometric parameter is minimized. The ionization signals are checked to determine if an abnormal combustion condition such as knock or misfire has occurred.

摘要： A four-cycle engine for a marine drive has an air induction device introducing air to a combustion chamber. The air induction device defines an intake port next to the combustion chamber. An intake valve is movable between open and closed positions of the intake port. A valve actuator is journaled on the engine body for rotation to actuate the intake valve at a set angular position. A setting mechanism is arranged to set the valve actuator to the angular position between advanced and delayed angular positions. A sensor is arranged to sense an amount of the air within the induction device. A control system is configured to control the setting mechanism based upon the signal of the sensor. The control system controls the setting mechanism to set the valve actuator to an angular position that is closer to the first angular position than a present angular position when the signal indicates that the amount of the air increases and a change rate of the amount is greater than a preset change rate.

摘要： A rotor has teeth on a rotor body. The teeth indicate fixed ignition timings for both of normal and reverse rotations. The teeth also indicate beginning positions of a calculation ignition sequence and an excess advanced ignition sequence for both of the normal and reverse rotations. One of the teeth is longer than the other teeth to provide a signal for determining a rotating direction based on a detected signal from a timing sensor. In a stable rotating condition, a countdown process begins when the beginning position located on the forward side in the rotating direction from the cylinder to be ignited is detected, and the spark plug of the target cylinder sparks when the counting process finished.
