摘要： The invention relates to a method for combustion engines capable of sorting out false indications of a knocking condition, and in a closed loop manner influencing the control measures initiated in order to cease the knocking condition. With the aid of a gap biased by a measuring voltage and arranged in the combustion chamber is an ionisation signal obtained, which signal is characteristic for the ionisation during a combustion. A knocking condition could be detected from the determined intensity of the knock characteristic frequency content (KI) filtered out from the ionisation signal. In the inventive solution is also an integrated value (CQ) of the ionisation signal used in order to influence knock control measures. Knock control measures (82-87) are initiated at a first spontaneous knocking condition only if also the integrated value (CQ) from a combustion experiencing a knocking condition is increased in relation to preceding non knocking combustion (CQREF_NORM).Further on is also the speed of retrun (KTSTEP, IgnRET_STEP) back to ideal basic control data accelerated, dependent of the degree of reduction of the integrated value ( DELTA CQREL), following a correction of basic control data initiated in order to cease the knocking condition.

摘要： Method and arrangement for a capacitive ignition system in an internal combustion engine. In this, the discharging and charging of an ignition capacitor (24) is controlled by a control unit (40) which actuates a first circuit-breaking element (14) in a discharging circuit and a second circuit-breaking element (30) in a charging circuit. The ignition spark which is obtained in an ignition circuit on discharging of the ignition capacitor via the primary winding of an ignition coil is certainly powerful, but of short duration. Under certain operating conditions it is difficult for such a spark to ignite reliably in particular a lean fuel/air mixture. For the purpose of prolonging the said ignition spark, the present invention is chiefly characterized in that the control unit (40), at a time following the ordinary ignition time, actuates the second circuit-breaking element (30) in such a way that this is kept conductive simultaneously with the first circuit-breaking element (14). Current is then supplied from an electrical energy source (33) and via the primary winding (10). Thereafter, the control unit (40) actuates either of the circuit-breaking elements in such a way that the current supply via the primary winding (10) is interrupted, by which means a renewed ignition voltage generation is obtained which prolongs the ordinary ignition spark.

摘要： A method and arrangement for controlling, in a multicylinder four-stroke internal combustion engine, the spark ignition in at least two cylinders (C1, C3) the pistons of which simultaneously assume a top dead centre position. In, for example, a four-cylinder Otto-cycle engine, where the ignition distribution is controlled by an electric control unit (3) only as a function of an output signal of a crankshaft transmitter (5), ignition sparks on starting are generated simultaneously in two or all cylinders (C1 - C4). The charging of an ignition capacitor (20) must therefore be utilized for generating the ignition simultaneously in several cylinders, which can entail starting problems in the case of a low supply voltage from a battery (35). The present invention has the object of increasing the possibilities of a more reliable start with low supply voltage in an abovementioned engine. For this purpose, the charging and discharging of an ignition capacitor (20) is controlled by the control unit (3) in such a way that, at the time in which the pistons in the said two cylinders (C1, C3) pass through one and the same crankshaft angle range close to the top dead centre position, ignition is generated in first one and then the other cylinder (C1 and C3, respectively). Between the times for generating the ignition, the ignition capacitor (20) is charged so that a full charge is utilized for generating the ignition sparks in the cylinders (C1, C3).

摘要： An ignition unit included in the ignition system of an internal combustion engine and including a plurality of finger-like connection pieces (2) extending from a common upper part (4) in the ignition unit and connectible to a corresponding number of spark plugs in the engine, said upper part including an electronic unit with components included in a high-tension block, each connection piece (2) including an ignition element (20) with an ignition coil for generating ignition voltage, as well as a connection device (22) for connecting and for transmitting high-tension current to the engine spark plugs. The invention has the task of enabling rational manufacturing and design of an ignition unit, which meets high demands for loss-free and reliable voltage transmission between parts included therein. To this end, the invention is distinguished substantially in that each ignition element in the ignition unit has cable-free electrical connection both to contact means (47) in the upper part (4) and to contact means (27) in its connection device (22). The implementation reduces risk of electrical faults, which may also be explained by each ignition element (20) being enclosed in a surrounding protective sleeve (18).
