摘要： A method for carrying out an ionic current measurement in an internal combustion engine using a lean fuel mixture which requires an increased burning duration, in which method a combustion start/a failed combustion start is detected, after which the ignition spark is cut off and the ionic current measurement can be done. The combustion start can be detected by means of a measurement of the change of the burning potential and/or the burning current, detected at the low tension side of the secondary coil of the ignition system by means of leak capacitances of the ignition coil or by means of a separate winding of the ignition coil. The ignition spark is cut off by means of a controllable ignition magneto.

摘要： The invention relates to a generator arrangement, in particular in ignition systems for internal combustion engines. The arrangement comprises a multi-legged core (9) of magnetically conducting material with the legs (10-17) radially projecting towards a cooperating magneto flywheel (1), which exhibits a section with unsymmetrical magnetic flux (between 4 and 5). The legs carry uniformly wound windings (18-25) and are connected in two groups in the case of a one-cylinder internal combustion engine. The one group comprises two windings (18, 25) interconnected such that they only deliver an induced voltage (28, 29) when passed by the unsymmetrical section. The other group (19-24) delivers an induced sum voltage. The voltage of the first mentioned group controls the ignition process whereas the second group charges a capacitor, component of the ignition system.

The arrangement is composed of a multi-leg core (9) of magnetically conducting material having its legs (10-17) radially projecting towards a cooperating magneto flywheel (1). The magneto flywheel has one section (5) of an extension corresponding to two core legs and with an unsymmetrical magnet flux (between 4 and 6), and one section having as many north poles as south poles. The legs carry windings (18-25) uniformly wound and connected into groups.

The second group (19-24) emits an induced combined voltage. The voltage of said first mentioned group controls the ignition process, whereas the second group charges a condenser, component of the ignition system.

摘要： An apparatus and method for use with a carbureted internal combustion engine that accurately controls the amount of fuel that passes through the carburetor into the combustion chamber of the engine. A controlled triggering system controls the activation and deactivation of a solenoid. The solenoid, in turn, operates a plunger that varies the flow of fuel during the fuel intake cycle of the engine depending on the amount of fuel needed by the engine under any operating load. Thus, an engine can run leaner under partial load and run richer during periods of load and acceleration. By controlling the air-to-fuel ratio lower engine emissions and fuel consumption can be achieved.

摘要： An apparatus and method for use with an internal combusting engine that accurately control ignition timing. Reference signals are created which are used to determine both the mean engine speed as well as irregular speed. Control logic uses this engine information to accurately predict the future rotational position of the engine. The ignition timing is then adjusted to release the spark at the appropriate time.
