Description
The utility model is relevant with the car accumulator ignition mechanism.
Traditional car accumulator ignition mechanism is by storage battery, spark coil, and distributor, capacitor and spark plug are formed.Spark coil is actually a transformer that utilizes the mutual inductance principle to make, and as elementary, high-tension coil is as secondary, and is cored by low voltage winding.The function of distributor is to connect and the cutoff low circuit, makes spark coil produce high-tension electricity, and high-tension current is distributed to the spark plug of each cylinder by the job order of motor.It mainly is made up of circuit breaker and distributor.The function of circuit breaker is to connect and the cutoff low circuit.It is mainly by fixed contact and movable contact, and cam is formed.The split fire head of distributor and cam are contained on the same axle, are driven by the timing gear on the engines distribution cam axle.Capacitor is the element of store charge, and is in parallel with circuit breaker.Spark plug is an arcing inter space device that feeds cylinder.During igniting, high-tension current produces electrical spark in spark plug two clearance between poles, the mixed gas in the some gas cylinder.The contre electrode of spark plug and other electrode gap are 0.6-0.7mm, are to discharge between two electrode ignitions during discharge.Traditional battery ignition device ignition energy is lower, and the intensity of electrical spark is low, can not satisfy the automobile engine high pressure ratio that contracts, the needs of lean combustion.
It is big that the purpose of this utility model provides a kind of ignition energy, electrical spark intensity height, flame propagation speed, the automobile electromagnetic vibration ignition mechanism that ignition area is big.
The utility model is by power supply 1, spark coil 2, and distributor 3 and spark plug 4 are formed.The coils from parallel connection of coils of hertz oscilltor 5 is elementary in spark coil 2, the C contact of hertz oscilltor coil connects power cathode by contact (6), contact (6) is made up of fixed contact and movable contact, lays respectively on contact point arm support (14) and the contact spring arm (15).
The utility model has capacitor 7 in parallel with contact 6.
The contre electrode 8 of spark plug 4 of the present utility model is the garden cylindricality, and other electrode 9 is that annular cooperates with garden cylindrical electrode 8, and annular space 10 is arranged.
The utility model can have metal garden shape cap 20 to be connected with magnetic core 21 with contre electrode 8, and garden shape cap 20 has annular space 10 with other electrode 9.
The distance in the gap 10 of spark plug 4 of the present utility model is 1.2-2.5mm, and the degree of depth of the other electrode of annular is 5-8mm.
When the utility model is connected power supply, contact 11 closures of the circuit breaker of distributor 3, electric current the flow through elementary winding of spark coil 2 and the coil of hertz oscilltor 5, their electric current all increases rapidly, produces magnetic flux in the iron core energy storage.When contact breaker points 11 disconnected under the effect of the cam 12 of distributor 3, the rapid dyingout of the magnetic flux of spark coil 2 went out high-tension electricity and makes spark plug sparking by certain firing order at the secondary induction of spark coil 2.When the coil electricity of hertz oscilltor 5, because producing magnetic force, its iron core contact 6 is disconnected below the contact spring arm is inhaled, the shunt circuit is cut off, magnetic force disappears, rely on the elastic force of contact spring arm to make contact 6 closures again, circuit is switched on again, so repeatedly vibration.
When contact breaker points 11 disconnected, the primary current of the spark coil hertz oscilltor coil of flowing through made its contact 6 bonding, and at this moment the break-make of elementary winding of spark coil and hertz oscilltor coil current is by hertz oscilltor 5 controls.Because the continuous open and close of hertz oscilltor contact 6, and make the inferior utmost point of spark coil when contact breaker points 11 breaks, produce pulsed high-voltage to the moment of a certain cylinder igniting, so between all gaps, the garden of annular spark plug, produce annular many sparks effect, ignition energy improved greatly.Metal garden shape cap 20 closely contacts with magnetic core 21 with contre electrode 8, and the heat that sparkover produces can scatter and disappear by magnetic core is very fast, and the heat of the other electrode 9 of annular also scatters and disappears easily.
The utility model is simple in structure, can not change the basic structure of ignition system, and only additional the and annular spark plug that changes the outfit gets final product with hertz oscilltor.The utility model ignition area is big, the energy height, and flame propagation speed can be improved engine power performance, acceleration performance, fuel-economizing, indexs such as toxic emission and noise are improved and long service life, reliable operation.

Following is embodiment of the present utility model:
The utility model is by storage battery 1, spark coil 2, and distributor 3, hertz oscilltor 5, electric capacity 7,13 and spark plug 4 are formed.Breaker cam 12 is contained on the same axle with the split fire head 18 of distributor, and contact breaker points 11 can disconnect under the effect of cam 12.
Spark coil 2 elementary has additional resistance 19.Hertz oscilltor 5 is parallel to elementary (a of electromagnetic oscillations hertz oscilltor 5, the b wiring terminal is connected to a among Fig. 2, the b point) of spark coil 2.The electromagnetism device coil that shakes connects the C wiring terminal, and by contact 6 ground connection, capacitor 7 is in parallel with contact 6.The effect of capacitor 7 is:
1, when elementary electric current (electric current that contains oscillator coil and spark coil) disconnects, can quicken magnetic field and disappear, thereby improve secondary voltage.
2, weaken the spark of contact 6, prolong the working life of contact 6.
