Definitions

  • the present invention has for object a ignition integrated system for I.C. motors.
  • the innovation finds particular even if not exclusive application in the small I.C. motors with one cylinder 2 phases in different sectors, as motorvehicles, etc. However the invention can be used in other I.C. motor sectors.
  • this I.S. includes: - a capacity reloading winding on one leg of the lamellar package by which eventually is made even the SCR Pick-up command; or said Pick-up is made separate with a further winding.
  • - a primary winding and a secondary concentric winding and coaxial but misaligned in respect of the axis of reloading winding.
  • said first winding is a condenser winded element at controlled impedance with the triple function of: - primary winding; - condenser as capacitive means; - command of the spark discharge moment means, already defined as element of TRIGGER (start) for the SCR.
  • TRIGGER start
  • Figure 1 represents a view of the electric schema of the ignition device.
  • Figure 2 represents a path diagram of the tension (voltage) to noticeable vacuum in the respective three windings during their operative cycle with tension positive and negative values.
  • Figure 3 represents a view of a first forms of realization of the stator device.
  • Figure 4 represents an alternative solution to the previous solution figure.
  • PI indicates the "U" stator lamellar package which legs are disposed adjacently gap to a magnetic known rotor for the variation of the flux in the same lamellar package PI.
  • a shank of the lamellar package includes at least in coaxial winding: - a first sheet roll winding with alternation of at least two conductor surfaces/sheets (Lp1/Lp2)-surfaces/insulating sheets with respective four electric conductive terminals (1 , 2, 3, 4) forming in the ensemble a condenser winded element at controlled impedance that acts as primary winding (L1 ), by capacitor (C) and by element of "TRIGGER" (start) for the SCR; - a second secondary electric conductor wire winding bobbin (L2) to increase the induced tension (voltage) at a value of discharges in the ignition plug (Cd) ; - a third electric conductor wire winding bobbin (L3) with reloading function of the capacity (C
  • the primary winding (L1 ) and secondary winding (L2) can be respectively internal/external or viceversa, while the reloading winding (L3) is set in head.
  • the electric schema is shown in figure 1 in which the inductive capacitive roll L1 (the capacitive function is indicated with “C " presents four electric conductive terminals 1 , 2, 3, 4.
  • the second connection of the first sheet/layer winded conductor Lp1 placed in the opposite side of the first, results utilizable for other purposes.
  • the first connection 3 of the sheet/iayer conductor Lp2 is connected by means of diode (D4) and resistances R1 .R2 (with function of resistive divider) to the "GATE" G of the SCR that makes bridge between the first connection (1 ) and the mass, being furthermore provided a bridge to diode D3 downwards.
  • D4 diode
  • R1 .R2 resistances R1 .R2 (with function of resistive divider) to the "GATE" G of the SCR that makes bridge between the first connection (1 ) and the mass, being furthermore provided a bridge to diode D3 downwards.
  • the secondary is indicated with L2 and the ignition plug for the discharge of the spark is indicated with Cd.
  • the actuation happens as follows:
  • the reloading winding L3 during the rotation of the rotor with magnetic insert presents a difference of potential which path is visible in the figure 4 and so such to polarize directly, for a certain time the loading diode D2, consequently the current can flush by the third winding L3 through the loading diode D2, from the terminal 1 to the terminal 4 of the first winding (condenser winded element at controlled impedance), realizing the charge of its capacity (C), closing then on the winding of reloads L3 through mass.
  • the recirculating diode D1 allows a current circulation that limits the negative potential on the reloading winding L3 to compatible values with those acceptable by the loading diode D2.
  • a positive potential respect to mass is present on the terminal (3) of the first winding (condenser-inductance), such to polarize directly the control diode D4 and the "GATE" of the SCR through the resistive divider R1 .R2, having so the prime of the SCR, determining ultimately the instarrt of sparks that discharges on the plug Cd, connected to the secondary winding L2.
  • said first winding which capacitive winded element at controlled impedance (adopted even in IT-83550A/88 which can be useful for its construction), being coaxial and concentric with the secondary winding (L2), presents with the last a coupling decidedly better respect to the third reloading winding means (L3), that is placed in head.
  • This solution allows a good energy transfer between the first winding (capacitor winded element at controlled impedance) and the secondary winding ( L2) .
