IC engine speed limiting system - has electric circuit transmitting signal when preset max. speed is attained to actuate ignition point adjuster

The output signal of the circuit (15-24) rapidly retards the ignition point by an electronic adjuster. In addition to the speed limiting, the device provides a fuel mixture regulation. In this manner the device provides a sudden and quick speed limiting without overheating of the engine. The overheating is prevented by simultaneous fuel mixture control which, even with some retard, prevents excessive overheating. The battery voltage is transformed to higher d.c. voltage. This is used for charging a capacitor via a resistor, which is discharged by ignition of a thyristor over the prim. of the appropriate ignition transformer. A thyristor is associated with each cylinder.PS.

Electronic ignition system for internal combustion engines

An electronic ignition system for an internal combustion engine. In a first embodiment an input pulse is generated by a pick up (10) at the same point in each revolution of the engine. Clock pulses at a first pulse rate are counted in an up counter (22) between consecutive input pulses. The resulting count signal is transferred to a down counter (30) which, between the consecutive input pulses, counts down at a faster rate. For an eight cylinder engine this faster rate is four times the first pulse rate, for a six cylinder engine it is three times the first pulse rate, and for a four cylinder engine it is twice the first pulse rate. In a second embodiment a computed count signal is preset into a down counter which is then counted down. In each embodiment, when the down counter reaches its zero count level the count signal is againt preset into it so that it recycles. Each time the down counter passes a preselected count level, an output pulse is generated. Four output lines are provided ...

IGNITION SYSTEM WITH ADDITIONAL FUNCTIONS

A microcomputer is used in the invention for control of the ignition functions of an ignition system of an i.c. engine. A switch in an operating handle or the like is connected via a transistor to a digital input of the computer. This reads the status of the switch once every revolution of the engine and as long as the switch is closed the ignition is delayed at an r.p.m. above a predetermined, programmed value (e.g. 3000 r.p.m.) and the r.p.m. of the engine is restricted. When the engine shall work the switch is opened and the ignition is normal. The restriction is used at start in order to avoid speeding during the start procedure. As a complement to said switch a parallel switch can be connected and operated by a brake device of the engine. During braking the r.p.m. of the engine is thereby restricted to the same value as the r.p.m. during the start.

ELECTRONIC ENGINE RPM LIMITING DEVICE

Ignition module with rotational speed limitation for an internal combustion engine

A revolution threshold regulator and/or toggle switch has a first and a second fixed phase source of alternating current having a frequency proportional to the revolution speed of a rotor of an internal combustion engine. A trigger device scans the alternating currents to emit a control signal at a revolution threshold above or below a preset revolution threshold. The trigger device has a timer module which cooperates with one of the alternating current sources through a trigger charge element which can be discharged via at least one discharge path to create a control signal. The trigger charge element, as it discharges, sends a control current through a series Zener diode in a blocking direction to the control signal output.

Idling control system for internal combustion engine

An idling control system for a two-plug type internal combustion engine is comprised of an idling detector, an engine rotation speed detector and a controller coupled to the detectors. The controller decides whether the engine rotation speed in idling is smaller than an idling speed by a predetermined value. When this decision is affirmative, the controller differentiates ignition timings of the two spark plugs of each cylinder. This arrangement enables the engine with this system to perform preferable idling performances of generating a torque in response to the input of the external torque and of continuing the combustion against the drop of the engine rotation speed.

Engine revolution controller of working machine

In an engine of a working machine having no governor mechanism, the engine revolution speed is controlled such that the revolution speed can stably be maintained irrespective of the variation in load without adjusting the throttle opening to exploit the full potential of the engine. Since an engine 1 does not have the governor mechanism, an operator adjusts the throttle opening and controls the engine revolution speed. A map in which ignition timing (amount of angle of lead) is set by means of functions of the engine revolution speed is stored in an ignition timing map 30 . The map 30 is set such that the engine revolution speed is equal to or higher than a value to be controlled (e.g. 7000 rpm), and the ignition timing is lagged as compared with a case in which the engine revolution speed is lower than the value to be controlled.

ENGINE CONTROL METHOD AND SYSTEM FOR SMALL VEHICLE

PROBLEM TO BE SOLVED: To improve vehicle travel performance by reliably preventing a driving wheel from slipping and a front wheel from floating and preventing an engine output limit from occurring at an unnecessary time, in a small vehicle where rotation of a spark ignition type engine is transmitted to a rear wheel via an automatic transmission. SOLUTION: During acceleration of the engine, an excessive degree of rotational variation in a crankshaft is detected to limit the output of the engine. The degree of rotational variation can be computed from a ratio t/T of a passing time t of a predetermined constant angle region of a rotor rotated integrally with the crankshaft to one period T of the rotor. The degree of rotational variation can be, for example, a difference or ratio between such ratios t/T each for one or two crankshaft rotations. The rotor may be rotated synchronously with the crankshaft. COPYRIGHT: (C)2003,JPO ...

Internal combustion engine control method

Vehicle, and its control method

When a demand power (Pe*) is at or higher than a threshold value (Pref2) (at S110 and S260) while a vehicle being stopped, the engine speed at or higher than a relatively low-limit speed (Nemin2) is set (at S290) to a target speed (Ne*), and a target timing (TV*) is so set (at S300) on the basis of the target speed (Ne*) that the change to a spark advancing side is smaller than that at the time of operating the engine for a run. The engine is operated at the target speed (Ne*) while being followed by the ON/OFF of an intake valve at the target timing (VT*). As a result, it is possible to suppress the feel of disorder, which might otherwise be felt by a driver when the engine is operated at a relatively high speed. In accordance with the operated state of the engine, moreover, the ON/OFF timing of the intake valve can be better optimized to control a variable valve timing mechanism more properly.

DEVICE FOR THE ELECTRONIC ADJUSTMENT OF THE IGNITION POINT OF IGNITION SYSTEMS OF INTERNAL COMBUSTION ENGINES

Engine speed controller for working machine

In an engine of a working machine having no governor mechanism, the engine revolution speed is controlled such that the revolution speed can stably be maintained irrespective of the variation in load without adjusting the throttle opening to exploit the full potential of the engine. Since an engine 1 does not have the governor mechanism, an operator adjusts the throttle opening and controls the engine revolution speed. A map in which ignition timing (amount of angle of lead) is set by means of functions of the engine revolution speed is stored in an ignition timing map 30. The map 30 is set such that the engine revolution speed is equal to or higher than a value to be controlled (e.g. 7000rpm), and the ignition timing is lagged as compared with a case in which the engine revolution speed is lower than the value to be controlled.

Engine-condition-responsive cutoff apparatus

Apparatus for inhibiting the operation of an engine in response to engine speeds which exceed a preset number of revolutions per minute employs a cutoff circuit for detecting and shaping firing signals and a switch interposed in either the ignition powering circuit, or the fuel circuit of a diesel, which is operable upon a detected predetermined overlap of a shaped signal and the previous signal delayed a predetermined interval. The apparatus also utilizes temperature and pressure-sensing devices which are effective to operate the cutoff circuit in response to the detection of adverse temperature or pressure conditions within the engine. An engine cutoff device, i.e. a relay, is operated in response to a true output from an OR gate which has as its inputs the overlap detection circuit and the individual sensing devices. The cutoff device and the OR gate are also provided as a separate package for applications which require engine conditions detection other than overspeed detection.

Speed limitation for carburettor engines that are not yet warm

Die Erfindung vermeidet Motorschäden, welche auftreten können, wenn der noch kalte Motor mit einer zu hohen Motordrehzahl belastet wird. Insbesondere handelt es sich um folgende Schäden: Kompressionsverlust, hoher Benzinverbrauch, Ventilschäden. Da nicht jedes Fahrzeug mit einer Öl- bzw. Wassertemperatur-Anzeige ausgerüstet ist und nicht jeder Autofahrer auf die o. g. Anzeigen achtet, kann leicht die obere zulässige Kaltdrehzahl überschritten werden. Zur Abhilfe dieser Umstände dient ein Zusatzgerät, welches vom Motor die momentane Öltemperatur und Motordrehzahl aufnimmt. Diese Informationen werden in dem Zusatzgerät verarbeitet und entsprechend des momentanen Zustandes schaltet dieses ein Relais, welches den Zündstromkreis unterbricht, bis die zulässige Kaltdrehzahl erreicht ist. Durch die Schaltung ist garantiert, daß in der Warmlaufphase des Motors die entsprechende Drehzahl eingehalten wird. The invention avoids engine damage which can occur if the engine, which is still cold, is loaded with an engine speed that is too high. In particular, it concerns the following damage: loss of compression, high fuel consumption, valve damage. Since not every vehicle is equipped with an oil or water temperature display and not every car driver has to refer to the above. Displays, the upper permissible cold speed can easily be exceeded. To remedy these circumstances, an additional device is used, which records the current oil temperature and engine speed from the engine. This information is processed in the additional device and, depending on the current state, it switches a relay which interrupts the ignition circuit until the permissible cold speed is reached. The circuit guarantees that the appropriate speed is maintained when the engine is warming up.

Dual schedule ignition system

An ignition system for an internal combustion engine, such as an outboard marine engine, which includes an advanced timing schedule, a non-advanced timing schedule, and a circuit for switching between the two schedules or disabling both schedules based upon engine operating conditions. The ignition system includes an optoelectronic time base generator which produces two sets of timing pulses relative to crankshaft position which are non-advanced timing pulses and advanced timing pulses. The time base generator comprises a LED-phototransistor pair and an encoder disk attached to the crankshaft with slots to interrupt the emission path between LED-phototransistor pair. The non-advanced pulses are generated based upon the trailing edge of each slot while the advanced pulses are generated based up the leading edge, wherein the width of the slots indicate the degree of advancement of the advanced schedule over the non-advanced schedule. Both schedules are inhibited based on a high overspeed condition and a low overspeed condition when the engine is overheated, wherein there is a smooth transition between the two conditions.

In an ignition device for a capacitive discharge internal combustion engine, an ignition timing signal is calculated with a cycle detection signal obtained at a timing at which a forward voltage portion of an output voltage from a generator coil has reached a cycle detection voltage for making continual ignition operations available, and a peak voltage detection signal and a start-up voltage detection signal are obtained in accordance with a delayed reverse voltage portion of the output voltage from the generator coil. In a preset normal region speed or less in which a load is coupled to the engine, an ignition signal is output immediately after the peak voltage detection signal has been generated. In a normal region speed or more, an ignition signal is output after the duration of the ignition timing signal from the point in time of output of the cycle detection signal. At the time of start-up, an ignition signal is output in response to the start-up voltage detection signal according to the cycle detection signal. This eliminates the need of a coil for generating a timing signal and provides a safe start-up operation.

CONTACT NOW, OVERVIEW PROTECTED IGNITION ENGINE SYSTEM

System to prevent reverse engine operation

An ignition system for an internal combustion engine, such as an outboard marine engine, which includes an advanced timing schedule, a non-advanced timing schedule, and a circuit for switching between the two schedules or disabling both schedules based upon engine operating conditions. The ignition system includes an opto-electronic time base generator which produces two sets of timing pulses relative to crankshaft position which are non-advanced timing pulses and advanced timing pulses. The time base generator comprises two LED-phototransistor pairs and an encoder disk attached to the crankshaft with slots to interrupt the radiation path between each LED-phototransistor pair. The encoder disk is provided with a synchronizing slot, multiple timing slots associated with the cylinders of the engine, and an direction slot. The direction of the rotation of the engine can be sensed by the spatial relationship between the synchronizing slot and the direction slot. The non-advanced pulses are generated based upon the trailing edge of each timing slot while the advanced pulses are generated based up the leading edge, wherein the width of the timing slots indicate the degree of advancement of the advanced schedule over the non-advanced schedule. Both schedules are inhibited based on predetermined operating parameters of the engine or the detection of a reverse engine operation.

Zero-hysteresis engine rpm limiter

Apparatus for limiting the rotational speed of an internal combustion engine by monitoring the time interval between ignition impulses produced when a breaker switch in the primary circuit of the ignition coil opens. A pair of sequentially operable timers are started for each ignition pulse with the second time interval enabling a delay means coupled between the source of pulses and a control gate of a controlled switch connected across the breaker switch through an impedance. When a following pulse occurs during the second time interval, indicating a limiting rotational speed, the slightly delayed pulse triggers the controlled switch and the ignition pulse is shunted through the impedance with the resulting secondary voltage in the ignition coil being insufficient to cause a spark, thereby limiting the speed of the engine.

Semiconductor device

When a normal operation is detected by a self-interruption signal source and a first transistor is on, if an on-signal is inputted to an IN terminal, a second transistor is turned on and a third transistor is turned off. Accordingly, an IGBT is turned on. In this state, if an abnormality is detected by the self-interruption signal source, the second transistor is turned off and the third transistor is turned on. Accordingly, a gate terminal of the IGBT is connected to an emitter terminal via the first and third transistors, and charges accumulated by gate capacitance of the IGBT are rapidly discharged. Consequently, if a comparator detects that a collector voltage of the IGBT has exceeded a predetermined voltage, the first transistor is turned off, and gradual interruption in which the charges accumulated by the gate capacitance are gradually released by a resistor is performed.

TORQUE LIMITER FOR INTERNAL COMBUSTION ENGINE.

Vehicle and vehicle control method

When a power demand Pe* is not less than a preset reference value Pref 2 in a vehicle stop state (steps S 110 and S 260 ), a target rotation speed Ne* of an engine is set to a rotation speed of not lower than a relatively low minimum rotation speed Nemin 2 (step S 290 ). A target timing VT* is set according to the set target rotation speed Ne* to have a smaller degree of advance, compared with the setting of the target timing VT* in an engine operating state for driving the vehicle (step S 300 ). The engine is accordingly driven at the target rotation speed Ne* with an open-close operation of an intake valve at the target timing VT*. Such drive control effectively reduces the driver's uncomfortable feeling or odd feeling triggered by operation of the engine at a relatively high rotation speed in the vehicle stop state. The drive control also ensures the better open-close timing of the intake valve according to the operating condition of the engine and enables more appropriate control of a variable valve timing mechanism configured to adjust the open-close timing of the intake valve.
