Embodiment one:
Introduce structure and use condition that the utility model is used for single cylinder engine and the following multi-cylinder natural gas engine of 6 cylinders.Only be introduced in the multi-cylinder engine, and 2,3,4 cylinder machine ignition principles are the same with 6 cylinder machines with working method, are not described herein at this in conjunction with 6 cylinder machines.Be that example is narrated with 1190NT (single cylinder engine), 6190T (6 cylinder machine) below:
In conjunction with the accompanying drawings 3, because 1190NT is a single cylinder engine, without the distributor system, so the mode that sensor signal adopts flywheel to trigger obtains.Triggering magnet steel embeds in the flywheel outer rim then concordant with the flywheel face, Hall transducer is fixed on the fuselage near flywheel with a support, guarantee to leave gap, the 3mm left and right sides between sensor and magnet steel, leave two 44 * 25mm Luo bars on the sensor, be used for regulating this gap and fixation of sensor.According to the rotation direction of motor, when reaching the optimum igniting advance angle before piston runs to compression top center, the magnet steel on the flywheel is just also neat with sensing station, so just can trigger sensor and produce the ignition timing control signal during engine operation.This signal is a low level by D2 control T2b, and T2 ends, and T3b loses the driving signal that T2e sends here and ends, and T3 be by can interrupting high-voltage ignition coil B electrode current just, according to electromagnetic induction principle B just extremely in the instantaneous interruption of electric current can make B produce induced voltage.Pass to spark plug by high voltage wire after this voltage boosts by B the utmost point and produce spark, the compressed mixed gas in the some gas cylinder comes work done.Because the flywheel of motor is constantly running, after triggering sensor, magnet steel can leave very soon, sensor resets, T2b reverts to high level, the T2 conducting also promotes the T3 conducting, and the first utmost point of B1 flows through electric current once more magnetizes B1, when motor need be lighted a fire once more, magnet steel on the flywheel triggers working sensor again, has so just finished the continuous igniting task of motor.Because 1190NT is a four-stroke engine, whenever finish a work cycle flywheel and will change 2 circles, flywheel will change two circles and will trigger igniting mooring points secondary fire simultaneously in each acting circulation like this, and igniting for the first time is about 24 degree, to be used for lighting the mixed gas work done before compression top center; Refire time is 24 degree before exhaust top dead center, can be used to the carbon deposit on further burning of waste gas and the removing spark plug.
Narrate generator working procedure partly below again:
Generator mainly is used to provide the work energy of igniting system.Still be example with the 1190NT machine, because 1190NT uses is 24V starting motor and this igniting is to be operated in 12V, so make to start power supply with two 12V storage battery series connection, drawing the 12V terminal from the middle 12V of two batteries is work for igniting, as not removing behind the battery pack ato unit, need to adopt 28V alternator for vehicle and voltage regulator.In the accompanying drawing 2, d links to each other with f, and the voltage that generator sends guarantees to be no more than 28V under the adjusting of voltage regulator, and the 24V terminal is given batteries charging on three core skewer seats, is work for igniting simultaneously.As needing battery is removed behind engine start, in the accompanying drawing 2, c links to each other with d, needs to adopt 14V alternator for vehicle and voltage regulator.
When battery and three core skewer seats join, 24V voltage is only used for motor starting, 12V voltage one tunnel is given the power supply of igniting system through overcurrent fuse, flow for the whetstone magnetoelectricity that produces magnetic field to generator by ed, voltage regulator on another road, when engine start and after reaching certain rotating speed, the voltage that generator sends begins the power supply to igniting system, and keeps self required whetstone magnetoelectricity stream.At this moment just removable battery.
Narrate the situation that present embodiment is used for 6 cylinder machines below again, existing is example with 6190T type natural gas engine: because of ignition control circuit, generator, voltage regulator and starting circuit with on chat the same of single cylinder engine (1190NT), no longer narrate at this.Employed distributor triggering and branch fire were partly when main narration was used for 6 cylinder machines.Special shaft is put the structure of formula sensing contactless electron distributor and is seen accompanying drawing 3, puts the distributor of formula sensing arrangement with axle, and the life-span is longer more than 3 times than common distributor, and the gap that the wearing and tearing of distributor axis produce can not influence its work effect.Because the position of triggering dish is designed to and can transfers arbitrarily, so its initial trigger angle also can be provided with arbitrarily, can satisfy the triggering requirement of all distributors that forward reach counter-rotating, that is to say that any in the world employing distributor triggers, divides this kind of motor design of fire can both satisfy service condition.Distributor links (in conjunction with the accompanying drawings 4) by distributor live axle on distributor joiner and the motor, distributor live axle one end links by gear-box and engine crankshaft, drive its running by bent axle, its rotating ratio is 2: 1, be that bent axle commentaries on classics two circle distributor live axles turn around, the other end and distributor link, and drive the distributor rotation.Working procedure is as follows:
When engine start, the distributor axis drives the triggering dish and split fire head turns round with bent axle, before the motor cylinder runs to compression top center during the optimum igniting advance angle (6190T is 30 degree), magnet steel on the triggering dish should just trigger sensor, send ignition control signal to ignition control circuit, make firing circuit produce the igniting high pressure, this high pressure is passed corresponding cylinder separating line to the upper cover body through split fire head, by cylinder separating line height is sent to spark plug on the respective cylinder, spark plug produces high tension spark and lights in the cylinder compressed mixed gas and do work.The ignition cylinder preface of 6190T is 1-5-3-6-2-4, when the distributor three-sixth turn, should trigger once fire of each cylinder point in proper order by this, makes each cylinder of motor all finish an acting circulation.
Embodiment two:
Introduce the utility model and be used for situation on the 12 cylinder machines, existing is example with the 12V190T motor: the mode that adopts two covers or the above ignition system of two covers to form the work of taking turns gust when the utility model is used for the above multi-cylinder engine of 6 cylinders is come work.The purpose of doing like this is to reduce production costs, and brings convenience for maintenance in the future.Because of distributor of the present utility model and divide the fire lid all to adopt existing accessory on the automobile, but 6 cylinders are difficult for finding with the distributor of getting on the car, so the ignition system that present embodiment adopts two covers to be used for 6 cylinder machines is finished the igniting task of 12V190T motor.Because 6190T's is the same among the working principle of its ignition control circuit and the embodiment one, mainly narrates combined method and structure that two cover ignition systems are worked by turns here.2: 1 gear drive casees are used for the motor song low one times of rear driving breakerless distributor of prompt drop of walking around, so it directly with body on transmission device link and be fixed on the body, ignition controler, high-energy ignition coil, filter capacitor are then unified to be contained in a cabinet internal fixation on the shell of gear drive case 26.
The ignition cylinder preface of the 12V190T machine ignition system of being made up of with the utility model two covers, 6 cylinder machines is 1-8-5-10-3-7-6-11-2-9-4-12.Require bent axle to change 720 degree, the distributor three-sixth turn, during one times of the driving gearbox reduction of speed by 2: 1 speed ratios, ignition system will be given once fire of 12 cylinder each points according to this ignition cylinder preface.Promptly the ignition phase angle between each cylinder machine of 12 cylinder machines is 30 degree.
When the ignition cylinder preface of above 12 cylinders was divided into two groups, a distributor was responsible for the igniting of 1-6 cylinder, and its ignition cylinder preface should be 1-5-3-6-2-4; The another distributor is responsible for the igniting of 7-12 cylinder, and its ignition cylinder preface is 8-10-7-11-9-12.
Because the ignition phase angle between each cylinder of 12V190T machine has only 30 degree, and the ignition phase angle of the 6 cylinder machine distributors that present embodiment adopts is 60 degree, adopts stagger mutually 30 degree and be operated in the condition that could satisfy 12V190T machine ignition phase angle 30 degree under the fired state by turns of two covers, 6 cylinder distributors so have only.Minimum angle at two eccentric grove center lines of the main shaft of driving gearbox is 30 degree.
The ignition controler of 12V190T machine and the working principle of protective circuit are the same with single cylinder engine, enumeration and embodiment 1.
