摘要： Clock pulses are counted to provide a count indicative of speed in a counter that is reset with every revolution of a reference mark. The difference between successive counts is multiplied by a fractional factor, which is not necessarily the same for acceleration and deceleration, then added algebraically to the current count value. The acceleration-corrected speed value is then multiplied by a parameter-dependent digital value obtained from a summing circuit to which various engine condition parameters are supplied and the output of the last-mentioned multiplier is supplied to a comparator to which the current count of clock pulses beginning with the reference mark passage is compared. When the comparator finds the match, spark ignition takes place. Another counter counts the clock pulses following each reference mark for sequencing multiplexers that enable some components to serve in more than one operation, in effect controlling the flow of digital values around various loops in the circuit.

摘要： A dwell angle control has three counting devices for detecting acceleration. In a first UP/DOWN counter (17), the count in one direction takes place throughout the time the current in the primary circuit of an ignition coil (25) exceeds a current threshold value (I1). The count in the other direction is constant with respect to time. The counts on the first counter are taken over into a second UP/DOWN counter (11) in response to the input signal, the counting direction also being determined by the input signals. When the count in the second counter (11) reaches an adjustable trigger threshold value, the closure time is initiated, the actual ignition time being fixed by an edge of a sensed signal, or the edge of the signal from an ignition computer. The adjustable trigger threshold value is advantageously determined by a third UP/DOWN counter (12) which is set to a fixed value (X) by an edge of the sensed signal and whose counting direction is also determined by the sensed signals. A very good dynamic response is achieved by the detection of acceleration by three counters during different time periods. It is advantageous to switch from a decrease in closure angle to an increase in closure angle at an adjustable speed by switching the adjustable trigger threshold value to a very small value and switching the counter (11) to a continuous DOWN count. This allows a matching to variable ON/OFF ratios of the sensed signal.

摘要： In an internal combustion engine in which the fuel supply is interrupted during no-load operation to save gas the ignition timing is retarded following resumption of the fuel supply to cause the resumed torque to be applied slowly. A sequence of ignition timing signals following the activation of the gas pedal is delayed by sequentially smaller and smaller amounts until the normal ignition timing is resumed.

摘要： An ingition system for internal combustion engines has dwell angle control apparatus for controlling the switching times of an electronic switch (21) in the primary circuit of an ignition coil (22) in dependence on the signals of a rotating sensor (10) or an ignition computer (11). Specifically, speed dependent counting values are periodically generated in a counting apparatus (13) each being counted down in a further counting apparatus (14) controlled by an edge of the sensed signal or a computed signal. Upon reaching a presettable triggering counting value, the electronic switch (21) is closed (start of dwell period). This triggering value is set by periodic up and down counting processes in a control counter (17) the upwards counting being constant with respect to time and the count-down process being determined by the length of time of current flow above a settable current value through the ignition coil (23). This allows the counting process of the speed dependent counting value to be triggered and the electronic switch to be opened (ignition time) by a single sensed signal edge per cycle.

摘要： To prevent change of data in a non-volatile programmable, ready-only memory (25) forming, together with a microprocessor (23) a control unit, for example for an automotive vehicle, while permitting programming of the memory from an external programming unit (P, 1), an interface (3, 11, 12) is provided through which a release-enable bus (13) also passes, data being transmitted in accordance with a predetermined characteristic--even or odd parity--, the parity correctness being checked. If the parity is correct, an "enter" signal is provided on the release-enable bus for storing the data; if not, retransmission is attempted for a predetermined number of time, and if it cannot be correctly effected, a malfunction indication output signal is generated.

摘要： To permit use of shaft position transducers which provide needle pulses at predetermined angular positions of the crankshaft of an engine, such as Wiegand-type, and still enable generation of a counted dwell time even under transient conditions, or under low-speed conditions, the output from the Wiegand transducer is connected to a logic circuit which, under normal operating conditions, by use of a counter counts a predetermined time interval after opening of a switch in series with the ignition coil to determine the dwell period or initiation of current flow for a subsequent ignition event by resetting the counter with a reverse polarity subsequent pulse, thereby passing, upon reset, a predetermined count state which, similar to the normal counting of the count state, initiates closing of the switch. Thus, even though the normal counting time has not yet been reached, the reset operation of the counter will trigger closing of the switch and hence sufficient current flow through the ignition coil to store the appropriate electromagnetic energy therein for a reliable spark at the spark plug.

摘要： A switch connected in series with the ignition coil is "on" and "off," respectively, in the presence and absence of a pulse furnished by a pulse generator operating in synchronism with the crankshaft of the engine. If the pulse width of the pulses is too small for the current in the ignition coil to reach the minimum value required for ignition, the closing time of the series switch is advanced, while if the pulse width is too long, causing excess heat dissipation in the coil, the closing time of the switch is retarded. To accomplish this, a first digital counter counts downwards for a predetermined time and upwards for a time period in which the current in the ignition coil exceeds a predetermined current. Upon interruption of the current in the coil, the then-present value in the first digital counter is transferred to a second digital counter. The second counter then counts down at a predetermined rate until a predetermined count is reached. At this time, the series switch is switched to the conductive state.
摘要翻译：在与发动机的曲轴同步运行的脉冲发生器的存在和不存在的情况下，与点火线圈串联的开关分别为“开”和“关”。如果脉冲的脉冲宽度对于点火线圈中的电流来说太小，达到点火所需的最小值，则串联开关的闭合时间将提前，而如果脉冲宽度太长，则会导致多余的散热线圈，开关的闭合时间被延迟。为了实现这一点，第一数字计数器在点火线圈中的电流超过预定电流的时间段向下计数预定时间和向上计数。在线圈中的电流中断时，第一数字计数器中的当前值被传送到第二数字计数器。然后第二个计数器以预定的速率递减计数，直到达到预定计数。此时，串联开关切换到导通状态。

摘要： The actuation speed of an electromagnetic consumer is increased by means of a charged capacitor which is connected in series with a consumer at such a polarity that its voltage is added to that of the power source. In one embodiment, the capacitor is switched across the power source until it is charged and then it is connected in series with the consumer at such a polarity that its positive pole is grounded while the negative pole is connected to the consumer. In another embodiment, the capacitor is first charged through the electromagnetic consumer and then it is connected with its positive pole to ground and with its negative pole to the consumer.

摘要： To prevent stumbling operation of an internal combustion (IC) engine (E) during warm-up due to switching back-and-forth between control of the air-fuel composition of the mixture being applied to the engine based on a preset, rich mixture and controlled by a lambda sensor, the lambda sensor internal resistance is sensed and, when the internal resistance of the lambda sensor, when exposed to a rich mixture, is substantially less than when exposed to a fuel-lean mixture, an indication is thereby provided that the sensor has reached proper operating temperatures - see FIG. 3 - is capable of providing output voltages within the evaluation range of two threshold circuits (9, 10) which receive reference values from a voltage divider (6, 7, 8) and of resuming control based on the output voltages of the sensor. The minimum operating temperatures of the sensor are asymmetrical, with respect to lean or rich air-fuel mixtures being applied to the engine, to permit either uninterrupted control of the engine in accordance with a preset air-fuel mixture during warm-up or only by the sensor, after it has reached its operating temperature, thereby preventing back-and-forth switching between control based on the preset conditions and on output signals from the sensor.
