Abstract
The utility model is an electronic high-energy igniting device used in the motorcycle engine ignition system. In the device, the secondary coil of a transformer of the existing high-voltage ignition coils is divided into the upper and lower sections of windings; the upper winding is linked in series with a diode and electrically connected with a spark plug through a line; the lower winding is linked in series with a diode and is then linked with the upper winding in series; after the lower winding is linked in series with a diode, the lower winding is connected in parallel with a group of delayed discharge components, and then is electrically connected with a spark plug through a diode. The structure of the utility model is simple; the ignition time of the spark plug can be effectively extended; the problems of the short time of the continuous spark, the incomplete ignition of mixed gas, and the heavy exhaust are overcome.
Description
Technical field
The utility model is a kind of electronic type high energy ignition unit that is applied in the motorcycle engine ignition system.
Background technique
Motorcycle ignition system is made up of ignition, high-voltage ignition coil, spark plug three parts usually.This system requirements is between burn period, and the endurance of electrical spark is about signa.Consider the functional reliability of ignition, motorcycle adopts contactless capacitor discharge type ignition usually, but because capacitor discharge is exceedingly fast, the spark duration that makes spark plug produce is shorter, mixed gas can not get fully lighting, so can not satisfy the requirement of motorcycle ignition.
Summary of the invention
The utility model is that a kind of improved electronic type high energy ignition unit will be provided, and it can substitute existing high-voltage ignition coil, prolongs firing time effectively.The utility model only need improve on existing high-voltage ignition coil internal structure, the secondary winding that is about to transformer in the existing high-voltage ignition coil is divided into upper and lower two sections windings, after making winding and a diode being connected, be electrically connected with spark plug by circuit, the hypomere winding is with after a diode is connected, again with the epimere windings in series, and the hypomere winding is with after diode is connected, in parallel with one group of time-delay discharge assembly again, after the parallel connection, be electrically connected with spark plug through a diode.
The utility model is because only need carry out a little improvement in original high-voltage ignition coil inside, and used element is few, and is simple in structure, the plug ignition time is effectively prolonged, and fuel oil is fully burned, and has improved engine efficiency, save fuel oil, alleviated tail gas.
Description of drawings
Fig. 1 is a circuit structure diagram of the present utility model.
Among the figure: 1, ignition 2, tenminal block 3, tenminal block 4, transformer 5, insulation crust 6, epimere winding 7, diode 8, circuit 9, circuit 10, spark plug 11, diode 12, inductance 13, electric capacity 14, diode 15, hypomere winding 16, diode
Embodiment
With reference to Fig. 1, the utility model will have that the secondary winding of transformer divides upper and lower two sections coilings in the high-voltage ignition coil, behind epimere winding (6) series diode (7), be electrically connected with the spark plug (10) on right side; Hypomere winding (15) with connect with epimere winding (6) again after diode (16) is connected, simultaneously hypomere winding (15) is with after diode (16) is connected, in parallel with one group of right side time-delay discharge assembly again, after the parallel connection, be electrically connected with spark plug (10) through the diode (11) on right side.Among the figure, the time-delay discharge assembly is by the inductance (12) on diode (14) and its right side and after connecting, and the electric capacity (13) with the lower end is in series again.At work, send into transformer (4) from the firing pulse that ignition (1) is sent here by tenminal block (2), (3), primary air (15), (6) are gone up induced voltage of producing and are produced high pressure after by diode (16), (7) rectification, this high pressure is directly given spark plug (10) by circuit (9), simultaneously, induced voltage on the secondary winding (15) produces high pressure after by diode (16) rectification, and this high pressure is given electric capacity (13) charging rapidly by circuit (8) through diode (14).At this moment, the inductance on diode right side (12) is owing to the existence of self-induction, conducting immediately.Voltage on the circuit (9) is far above the voltage on the circuit (8), and diode (11) ends at this moment.When the high pressure on the circuit (9) continues to rise to breakdown voltage value, just, produce spark by spark plug (10) discharge.After the discharge, and then become low level on the circuit (9), and electric capacity (13) is gone up the high voltage electric energy of storage just by inductance (12), diode (11) through the right side leads to spark plug (10), spark gap along ionization continues discharge, diode (14) oppositely ends at this moment, not conducting, and inductance (12) is because the existence of self-induction, conducting immediately is so the high voltage electric energy on the electric capacity (13) when the inductance (12), can be delayed a period of time, the length of this time is with the relating to parameters of electric capacity (13) and inductance (12).So just realized the continuity of firing time effectively, remedied in the past that the discharge of electronics electricity firearm is exceedingly fast in the ignition system, made the short deficiency of spark duration.Diode among the figure (7), (11) are used for isolating firing pulse and delay pulse, avoid two group pulse voltages to interact, and start so can not influence the normal ignition of motor.
Claims (2)
1, a kind of electronic type high energy ignition unit, it comprises an insulation crust (5), transformer (4), the secondary winding that it is characterized in that transformer is divided into epimere winding (6) and hypomere winding (15), after connecting with diode (7), epimere winding (6) is electrically connected with spark plug (10) by circuit (9), hypomere winding (15) with connect with epimere winding (6) again after diode (16) is connected, and hypomere winding (15) is with after diode (16) is connected, in parallel with one group of time-delay discharge assembly again, be electrically connected with spark plug (10) through a diode (11) after the parallel connection.
