Definitions
- ABSTRACT An impulse generator for igniting combustion engines has an electronic circuit installed between the breaker points and the high voltage coil thereof.
- a first transistor has its emitter connected to the coil and its base connected to the points so that closing of the points causes actuation of the first transistor.
- the collector of the first transistor passes electric current through an electrolytic condenser to actuate a second transistor, thereby feeding the primary of the coil so that when the points open, the collector of the first transistor loses voltage and interrupts the collectoremitter passage of the second transistor to originate high voltage in the secondary coil.
- FIG-2 IMPUL SE GENERATOR TO IGNITE COMBUSTION ENGINES sparks in the ignition, thus providing total combustion of the mixture which sets in motion the various engine cylinders.
- the classic ignition as it is known is a high I voltage coil whose primary winding is fed by the continuous current of a battery.
- This circuit is cut, or interrupted, by the action of contacts known as points, installed within a mechanism generally known as a distributor. This interruption of the current" is synchronized to occur'at the critical moment of maxpands, and thus initiates the working cycle of the engine.
- duration of points constituting the breaker of the traditional ignition can be set at some 20,000 Kms., since they have to bear a cutting current the approximate value of which is 4 Amp. and a frequency of several times, such as four times, per cm gine cycle.
- a condenser is generally installed between the points and it absorbs the spark.
- the impulse generator of the present invention has been developed. Its essential purpose is to produce a series of continuous sparks in each of the spark plugs or ignition parts-each time the points are opened. At the same time, the frequency of the sparks will be higher than in the classic ignition system and the mixture compressed in each cylinder will thereby burn in its entirety. Thus, all of its potential energy will be utilized and at the same time less solid or gaseous residue will result.
- FIG. 1 is a circuit diagram of the impulse generator of the present invention.
- FIG. 2 is a wave diagram of impulse voltage occuring in the use of the device of FIG. 1.
- the proposed impulse generator circuit is installed between the high voltage coil A and the points or breaker (I-1), and has a first transistor (T-l), whose emitter (E is connected to coil A.
- the base (B,) of the first transistor is connected to the points (I-l Meanwhile, the collector (C of the first transistor connects to the base (B of a second transistor T-2), the emitter (E of which is grounded, and the collector (C of which is connected to the primary winding of the high voltage coil.
- collector (C of the transistor (T-2) is in turn shunt connected to a condenser (C-1) and resistor (R-l), whose components are connected to the base (8,) of the transistor (T-l
- C-1 and R-l condenser
- the capacity and resistance qualities of (O1) and (R-l) will be determined as necessary in practical application.
- An electrolytic condenser is connected between the direct connection of the two transistors.
- the cycle begins again. This will occur several times, example six times, during the period -'when the breaker contacts (I-1) remain open.
- the electronic circuit and specifically the aforesaid impulse generator, does not oscillate since the transistor (T-'l) is actuated, and accordingly transistor T-2 is actuated such that a continuous voltage is applied to the coil.
- the form of the wave produced in the collector (C- 2) is represented in FIG. 2 and, as can be seen, an impulse reverse to that of the wave is produced under V. Although of slight value, it is sufficient to actuate the transistor (T-l).
- Another of the beneficial effects obtained with the invention is the fact that the increased frequency results in a higher peak voltage at the coil outlet, this circumstance resulting in easy starting of the engine, even during very cold weather.
- Iclaimg 1 An impulse generator for use in igniting combustion engines which include breaker points and a high voltage coil, said impulse generator comprising:
- a first transistor having a base, a collector and an emitter
- a second transistor having a base, a collector and an emitter; said base of said first transistor being connectable to said breaker points; said emitter of said first transistor being connectable to the primary winding of said coil; electrolytic condenser means joining said collector of said first transistor with said base of said second transistor; said collector of said second transistor being con- 'nectable to said primary winding of said coil; whereby when said points are closed, a voltage is applied to said base of said first transistor, thereby actuatingsaid first transistor and causing a voltage to be applied to said base of said second transistor, thereby causing a continuous voltage to be applied across said primary winding; damping oscillator circuit means applied across sa'id collector and emitter of said second transistor for generating an oscillating voltage through said second transistor when said points are opened and the voltage applied to said bases of said transistors are reduced, whereby a voltage is induced.
- shunt means connecting said oscillator circuit means with said base of said first transistor and for feeding said oscillating voltage thereto, whereby a sequence of voltages are induced in said secondary winding of said coil.
