Description

Automobile, motorcycle high-energy igniter

The utility model relates to the internal combustion type petrol engine, specifically a kind of automobile, motorcycle high-energy igniter.

During engine operation, be to produce the outside acting of pressure by lighting gasoline and Air mixing gas.In carburetor engine, fuel oil and Air mixing gas are the electricity consumption spark ignitions, in order to produce spark at cylinder, just need the configuration ignition mechanism.

Though there are many comparatively advanced electronic ignition devices to come out in recent years, but traditional for various reasons battery ignition device and magneto ignition device are still generally using, their common drawback is: motor is easy to generate when the high, low speed operating mode and lacks fire, and spark duration is short, discontinuous, cold starting is difficult.

The purpose of this utility model just provide a kind of can increase substantially spark energy, vapour, the suitable automobile that rubs, motorcycle high-energy igniter, it is big that it has spark energy, longer duration and characteristics such as continuous can be improved the cold-start performance of motor, save fuel oil.

In order to achieve the above object; the technical measures that the utility model is taked are: this automobile; the motorcycle high-energy igniter comprises a spark coil L; its once end 1; 2 with switch starter S2; ignition switch S1; after being in series, ammeter A and circuit breaker S3 just be connected storage battery G; the negative pole two ends; the S2 two ends are parallel with additional resistance R; the S3 two ends are parallel with protection capacitor C 1; the secondary terminals 3 of spark coil L is connected with the active contact of distributor S4; each split fire head contact is linked in sequence with the spark plug h of each cylinder respectively; S3 and S4 are coaxial interlock; it is characterized in that: between the secondary terminals 3 that it also has a storage capacitor C2 to be connected in parallel on L was held together, C2 was encapsulated in the high-pressure connection line.

The utility model has the advantages that: 1, spark energy is big, compared with similar products, can improve more than 1 times, and sudden, continuity, persistency is good.2, can obviously improve the cold-start performance of motor, starting easily, and is clear-cut agile.3, fuel oil is fully burnt, energy saving reduces sooting of the spark plug, reduces discharge amount of exhaust gas.4, structure is very simple, and by standardized designs, adaptability is strong, no matter automobile, motorcycle, and also vehicle no matter just can be used as long as change connecting line, and is very convenient.

Fig. 1 is the circuit diagram of this igniter.

Fig. 2 is the installation position schematic representation of storage capacitor C2 among Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the circuit diagram of this igniter.Mainly form by power supply, spark coil, distributing disk (outage---distributor), capacitor, spark plug etc.Among the figure, G is a storage battery, and A is an ammeter; S1 is an ignition switch, and S2 is a switch starter, and R is an additional resistance; L is a spark coil; wherein N1 once holds, and N2 is a secondary terminals, and S3 is a circuit breaker; C1 is the protection electric capacity of circuit breaker; S4 is distributor (being called distributor again), and h is a spark plug, and C2 is a storage capacitor.The positive pole that is connected with of car battery connects to hold to connect commonly with negative pole commonly and holds (being commonly called as plus earth and minus earth) dual mode, and what this figure provided is plus earth.As seen from the figure, except that storage capacitor C2, this be one typical, a large amount of at present battery ignition devices that use.C2 is a distinguishing characteristics of the present utility model, and it is connected in parallel on spark coil secondary high pressure one side, because the adding of C2 will improve the starting performance of ignition performance and motor greatly, its working procedure is:

Closes ignition switch S1, the S2 that switches starting, engine start, distribution cam axle drives outage---the coaxial rotation of distributor S3, S4, makes the contact in the circuit breaker S3 closed repeatedly---open.During make contact, the elementary N1 winding of spark coil L has electric current to flow through, and path of current is: the negative pole of elementary winding N1 → additional resistance R → ignition switch S1 → ammeter A → storage battery G of positive pole → bonding of storage battery G → circuit breaker S3 fixed contact → circuit breaker S3 movable contact → spark coil L.The electric current of N1 is pressed index law and is risen, and forms magnetic field in the iron core of coil, and along with the growth of electric current, the magnetic field among the L has also to be strengthened thereupon.When opened the contact, primary current was cut off suddenly, and magnetic field rapidly disappears, the rapid variation in magnetic field all induces electromotive force in two windings of N1, N2, because the number of turn of the coil ratio N1 of N2 is much more,, generally can reach 15KV～20KV so secondaryly can produce high voltage.The electromotive force polarity that L produces is 3 ends for just, 1 end is for negative, negative pole is added on the end of h through positive pole → bonding of negative pole → G of R → S1 → A → G, and positive pole is added on the active contact of S4, meanwhile, 3 of L rectifies the utmost point and charges to C2, and charging current rises by index law, when charging voltage reaches place value, voltage on the C2 and the voltage on the L pass through spark plug h sparkover by each split fire head contact simultaneously successively, thereby the energy of spark is strengthened greatly.The last split fire head of S4 whenever turns around, and lights a fire once in turn in each cylinder.If will quit work,, cut off primary current and get final product as long as open ignition switch S1.

The effect of additional resistance R can improve the performance characteristic of igniting, when low engine speed is moved, and outage

Device time of closing contact is long, and primary current is bigger, and the resistance following temperature rising of R increases, thereby it is unlikely excessive to have limited primary current, avoids spark coil overheated; When motor moved under high speed, time of closing contact was short, and primary current is little, and the resistance of R so just can make primary current descend lessly, thereby improve the high speed ignition characteristic along with decrease of temperature diminishes.The effect of protection capacitor C 1 is: when open the S3 contact, electric current is cut off, the moment that disappears in magnetic field, winding elementary also can produce about 200～300 volts of self induction electromotive forces, and this self induction electromotive force can form spark equally between the contact, ablated easily in the contact, after inserting C1, self induction electromotive force can be charged by electric capacity, makes the contact can not produce spark, can prolong the life-span of contact; On the other hand, when C1 discharged, discharge current by elementary winding, quickened the disappearance in magnetic field with in the other direction, and secondary voltage is greatly improved.

Fig. 2 is the installation position schematic representation of storage capacitor C2 among Fig. 1.Among the figure, the 5th, high-pressure insulating ring, the 1st, the high pressure input interface, the 6th, the high pressure output interface, the 7th, common ground end interface, the 2nd, the M3 screw, the 3rd, connect lead, the 4th, storage capacitor C2.As seen from the figure, C2 is encapsulated in the high-pressure insulating ring, externally realizes being electrically connected by three interfaces, and insulating bush is by standardized designs, does safe and reliable, easy to use, highly versatile like this, is convenient to the seriation design.

This high-energy igniter is not only applicable to the battery ignition system of structure typing, extensive use, need improve the igniter of spark energy for other, for example magneto ignition system, solid-state ignition system etc. are suitable for too, just can use as long as change the high-pressure connection line of standardization, seriation design.
