Object of the invention

The present invention relates to an electronic oscillator equipment for the ignition of gasoline engines, which has been specially designed to increase engine performance with lower consumption and a very considerable reduction of toxic gases that are emitted from an imperfect combustion.

Background of the Invention

As it is known, in the engines of gasoline the ignition takes place by the jump of a spark through a spark plug located inside the explosion chamber.

In this sense, the solutions known to date consist of a high voltage coil, whose primary is powered by the direct current of the battery (12 v.). This circuit, is cut or interrupted by the action of contacts called platinum, installed inside the mechanism known as DELCO, supporting these an intensity of approximately 4 A. This power failure occurs in synchronization with the critical moment of maximum compression of each cylinder, so that there is an overvoltage (breaking outcurrent), which when induced in the secondary winding of the coil, produces a HIGH current VOLTAGE, which, through a distributor (pipe and delco lid), is conducted to the spark plugs causing inflammation of the compressed excla within the chamber of each cylinder at the time of the corresponding cycle.

With this type of ignition, the inflammation of the compressed mixture occurs instantaneously in 28.8% of its totality, initiating a flame front that propagates inside the cylinder chamber, creating turbulence of gases rich in hydrocarbons, which do not become fully inflamed prior to the opening of the exhaust valve, going outside through the exhaust pipe.

In order to partially alleviate these inconveniences, high coils with higher primary consumption (7 amps.) and more secondary voltage are released. The spark that is produced is harder, the creation of the flame front being more intense and 1% of burned gases increased, as the consumption that the platinos have to support in the breaker is greater, these deteriorate rapidly.

To overcome this problem, the first electronic ignition that incorporates a power transistor to break the coil is born and is sent at its base by the classic plates, but with a large decrease in the intensity they have to handle.

Currently, various engine manufacturers replace the platinum breaker with inductors or coils located inside the delco (as many as cylinders), which being in the presence of a rotating magnet, generate an impeller that commands the base of a power transistor , which governs the primary of the coil.

In all the cases mentioned above, inside the cylinder chamber, just keep jumping a spark.

Description of the invention

The electronic oscillator circuit that the invention proposes, solves to a large extent the current problems of air pollution, energy saving (fuel) and is based on the creation of several consecutive flame fronts, which in the same period of time (stroke of the piston), inflames the compressed mixture NINE TIMES, as there are nine continuous sparks in each spark plug, accompanying the piston in its work stroke in 3/4 of its travel and reaching up to 63.2% of the mixture accumulated, against 28.8% that ignites with a single discharge or spark of the rest of the ignitions.

In the beginning and when examining the previous paragraph, it seems to be clear that if a spark plug with a single spark lasts about 20,000 km, with nine they will last much less. But after the tests carried out, we see that the opposite happens, since they last more than 50,000 Kms. When analyzing the electrodes of a spark plug, you see that the part of the shell that covers them, is oxidation decomposition of the electrode material itself , that when they are hot due to the previous explosion, they come into contact with the turbulence of hydrocarbon-rich gases and a chemical reaction takes place, which is transformed into oxide. In the case at hand, this phenomenon does not occur, because when the gases come into contact with the electrode, it encounters a spark and becomes inflamed, not giving rise to the aforementioned reaction,

It is obvious to note that at higher combustion, engine performance increases and that to maintain them, we need a lower amount of fuel. Also, solid waste is much lower (carbon) and gaseous (carbon monoxide, sulfur, etc.) that come out of the exhaust, being able to certify that these decrease by 50% in the most unfavorable case, compared to those detected in any engine with another type of ignition.

Preferred Embodiment of the Invention

When the ignition key is activated, we have current in the circuit, when the motor starts rolling and at a certain moment, the closing of the breaker will occur (plates Fig. 3) or (impulse of the electromagnetic breaker Fig. 2) which causes the direct polarization of transistor T1. , then a voltage of 12 V. appears in the collector σ of this transistor, thus polarizing the base B and the emitter E of the transistor T2., which originates the supply of the primary winding of the HIGH coil. At the same time, in the collector σ of the transistor T2., A reverse dampened oscillation appears that is transmitted by the capacitor and the resistance C1 and R1 (time constant) reaching the base B of the transistor T1. , to which it polarizes thus initiating a new cycle, which will be repeated a series of times planned, in this case nine, during the time that the plates remain open or in the case of the electromagnetic breaker, the non-conduction time of the transistor T3. , when these are closed by the action of the cam, the The oscillator is blocked, since it is polarized directly to the transistor Ti.

It is not considered necessary to make this description more extensive so that any person skilled in the art understands the scope of the invention and the advantages derived therefrom.
