Description

A saver fuel and constant voltage for a car}

The present invention relates to a vehicle rated voltage maintenance and fuel saving device, and more particularly to a rated voltage maintenance device for continuously supplying a square wave pulse of about 13.2 volts or more to the positive electrode of the battery in the charging process of the battery. The purpose of the present invention is to save fuel by improving combustion efficiency through complete combustion of fuel by allowing strong sparks to be generated from spark plugs powered by batteries through the ignition coil.

In general, a motor vehicle is provided with a generator for generating electricity and a battery for storing the generated electricity, and when the electric power is generated, it is configured to supply the power required by the battery.

A vehicle equipped with a generator and a battery as described above is to be supplied with a large amount of power to drive the starting motor during initial start-up, at this time, if sufficient power supply is not made, the engine does not start smoothly There was a problem.

In addition, when the performance of the generator or the battery is degraded in the course of operation of the engine, and the reference voltage is lowered, the voltage supplied from the ignition coil that receives power from the battery and boosts the voltage is low, so that sparks generated in the spark plug are weakly generated. This can lead to unstable combustion by inhibiting complete ignition of the fuel.

In particular, the above unstable combustion will increase fuel consumption at the point of exhaustion of petroleum resources, resulting in lower fuel efficiency.

On the other hand, as described above, the battery that stores and supplies the important power in the operation of the engine has a discharge cycle of converting chemical energy into electrical energy and a charging cycle of converting electrical energy into chemical energy to perform a unique function. As it is known, the process is commonly known that when the sulfate (SO 4) is combined with the electrode plate during discharge, water is generated and the specific gravity is lowered, and when charged again, the combined sulfate is returned to the electrolyte and the specific gravity is increased. The structure is composed of an electrode of lead (Pb) and lead dioxide (PbO ₂ ) dipped in a concentrated aqueous sulfuric acid solution.

finally

Anode: Pb (s) + HSO ₄ ------- PbSO ₄ (s) + H + + 2e-

Cathode: PbO ₂ (s) + HSO _4- + 3H + + 2e- ------ PbSO ₄ (s) + 2H ₂ O

Batter solution: Pb (s) + PbO ₂ (s) + 2HSO _4- + 2H + ------ 2PbSO ₄ (s) + 2H ₂ O and

Similarly, chemical cell reactions occur.

Two electrode reactions produce insoluble PbSO ₄ , which is attached to both electrodes.

In addition, the battery as described above is a sulfate (SO ₄ ) that is stuck during the discharge (including self-discharge) during a long period of charge / discharge cycle occurs when it is stuck without being released during charging, This is the sulphation (sulphate softening) phenomenon, and the sulphation phenomenon is aggravated as the battery is discharged more and the number of charge / discharge cycles is higher, and the sulphate is generated even when the charge voltage is low. An insulating film covering the electrode plate in the form of a film by forming a bond with the electrode plate and SO ₄ bond in the active material layer, which blocks the passage of chemical and electrical reactions and reduces the voltage, capacity and specific gravity of the battery. will be.

In addition, automotive charging systems are typically designed to produce 14.2 volts, and a voltage of at least 14.1 volts must be supplied to maintain a battery charge of about 12 volts.

However, the highest voltage of a battery in a vehicle is only 13.9 volts even when there is no load, and when an electrical load such as a heater or an equalizer is added, the voltage drops to 13.7 volts. If the charge state continues, the voltage of the battery is lowered.

As such, when the voltage of the battery is lowered, the spark generated from the spark plug is weakly generated as described above, and thus there is a problem in that the fuel is not ignited smoothly.

In addition, since the battery is normally installed far from its position, the user of the battery does not immediately know the state of charge or discharge of the battery, which makes it difficult for a situation in which appropriate measures can be taken initially.

Accordingly, an object of the present invention is to maintain the voltage of the battery at the rated voltage so that the voltage boosted by the ignition coil maintains the normal voltage so that sparks are strongly generated in the spark plug, so that fuel can be completely burned. It is for the purpose.

The battery rated voltage holding device of the present invention for achieving the above object, a state that generates a drive signal by detecting when a voltage higher than the holding voltage of the battery is applied between the first and second power terminals of the battery A monitoring unit; A voltage generation unit connected to a pulse generator for generating a DC pulse in response to a driving signal of the state monitoring unit and supplying it to the first power terminal of the battery, and the first and second power terminals of the battery; Characterized in that it has a status display for visual display.

Accordingly, the spark from the spark plug which receives the voltage boosted through the ignition coil is maintained to maintain the rated voltage of the battery, so that the complete combustion of the fuel is fully promoted, and the user visually displays the battery voltage level. By the status display unit to determine the efficacy of the device and the charging status of the battery.

Therefore, the user can not only know the current state of charge, but also visually confirm how much the voltage of the battery is kept constant by counting the number of light-emitting diodes after mounting the rated voltage maintaining device.

The above description is weak. In FIG. 4, when the light emitting diodes LE1 to LE3 are configured to have different colors, the user can easily check the charging state even by looking at the color emitted.

The operation of the battery rated voltage holding device 100 having the above configuration will be described below.

An example in which the rated voltage holding device 100 is mounted on a cigar jack in a typical passenger car will be described. The holding voltage of the battery 1 is typically about 12.5 volts or less while the start of the passenger car is turned off. Accordingly, the state monitor 30 in FIG. 1 senses that the voltage applied between the first and second power terminals (+,-) of the battery 1 is 12.5 volts and does not generate a driving signal. In detail, the reference voltage for determining the turn-on condition of the transistor 38, which is the driving switch, is set by the diode 32, the resistor 34, and the variable resistor 36 in the voltage detector. Therefore, if the variable resistor 36 is adjusted in advance so that the transistor 38 is turned on near about 13.2 volts, the transistor 38 is turned off because it is 12.5 volts or less in the state that the starting is turned off as described above. Keep it. As a result, the collector terminal of the transistor 38 has a voltage of 12.5 volts or less, but the current cannot flow to the emitter terminal. Since this becomes " high " at the logic level of the voltage, the oscillator 20 in the pulse generator is turned off so that the oscillation operation is not performed. Accordingly, the logic level " low " Is off. Therefore, since the transistor 40 does not perform the switching operation, no counter electromotive force is generated in the coil 18 in the DC pulse generator 10. Therefore, when the start is turned off, the inside of the rated voltage maintaining device 100 is turned off. Operation is all shut off, so little current is consumed.

When the passenger car is started, a generator (or alternator) which is a generator in the engine room of the passenger car usually performs three-phase alternating current generation. When the rectifier inside the generator that converts the AC power generation into a DC voltage performs rectification, and converts it into DC, the receiving rectifier outputs a DC voltage of about 13.2 to 13.8 volts as a charging voltage. Accordingly, the state monitor 30 in FIG. 1 detects that the voltage applied between the first and second power terminals (+,-) of the battery 1 is 13.2 volts or more and generates a driving signal. Specifically, since the variable resistor 36 is adjusted to turn on the transistor 38 near about 13.2 volts, the transistor 38 is turned on. As a result, current flows from the collector terminal of the transistor 38 to the emitter terminal, and the voltage at the collector terminal is lowered to the ground level. This becomes " low " at the logic level of the voltage, so that the oscillator 20 in the pulse generator is turned on to perform the oscillation operation. Here, the inverters 22 and 24 in the oscillator 20 are expressed in an equivalent circuit, and are an oscillating integrated circuit " 4584 " set to generate frequencies of 9 to 12 kilohertz (KHz). As a result, a logic level " high " is applied to the base of the switch 40, which is a switch, at a cycle of about 10 kilohertz and is turned on. Thus, the transistor 40 alternates between turning on and off the switching operation at a frequency of about 10 kilohertz. As a result, the current path to the ground through the emitter of the transistor 12 of the diode 12-resistor 14-capacitor 16-inductor coil 18-transistor 40 in turn is described above. It is formed at a frequency and then cut off and then repeated. Accordingly, the counter electromotive force is generated in the coil 18 in the DC pulse generator 10 each time, and is supplied to the first power supply terminal (+) of the battery 1 as a DC pulse. In this case, the application path of the DC pulse is a path from the node N1 to the first power supply terminal (+) through the diode 12. Therefore, a square wave pulse of about 13.2 volts or more is continuously supplied to the positive electrode plate through the positive electrode of the battery as several tens of kilohertz. In this case, the square wave pulse is a current of about 2 A (amps). As a result, the crystallized sulfate accumulated in the battery plate is reactivated to become active sulfur molecules, which are returned to the electrolyte, which is the battery solution.

On the other hand, in the case of an industrial battery, it is desirable to emit a powerful 4A pulse, it can be given a variety depending on the type of battery used. In addition, the instantaneous cell voltage (during pulse generation) during the pulse generation rises more rapidly than the normal battery voltage, and this instantaneous and continuous pulse voltage removes sulfate softening and maintains the shape of the negative electrode plate, thereby making the battery optimal. .

Therefore, when the performance of the battery is improved by the operation of the circuit as described above, the user can immediately check the level of the battery charging voltage within the location where they are located without opening the bonnet of the vehicle. In addition, the efficacy of the battery rated voltage maintenance device can be easily verified.

Although the above-described present invention is described according to the drawings and defined by way of example, various changes and modifications may be made without departing from the technical spirit of the present invention according to matters. For example, the present invention is limited to the case where the display is mounted on a passenger car and displayed using a light emitting diode. However, when the case is different, the state of charge may be notified by voice or may be mounted elsewhere.

Therefore, the present invention has a rated voltage holding device for continuously supplying the positive electrode of the battery as a few tens of kilohertz in the charging process of the square wave pulse of more than about 13.2 volts, the ignition coil powered by the ignition coil The fuel can be saved by improving the combustion efficiency through the complete combustion of fuel by allowing strong sparks to be generated in the plug.

In addition, the user is provided with a status display for visually displaying the voltage level of the battery, it is very useful to visually check the efficacy of the device and the charging status of the battery.
