Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a combustion device for an internal combustion engine by high temperature gasification and atomization.

[0002]

[Prior art]

 When starting a conventional engine, when the temperature is low, it will not start unless a rich air-fuel mixture is sent, and even if the temperature rises, the air-fuel mixture becomes uneven and incomplete combustion occurs. Although it is burnt out, the purification capacity is gradually decreasing due to unburned carbon. Therefore, the present applicant has proposed Japanese Patent Publication No. 61-10664.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned proposed technology is not sufficient to deal with a multi-point electronic fuel injection type gasoline engine that directly injects fuel and to prevent loss due to the power load of the power source.

The present invention heats the electric heater coil and induces a slight vibration to increase the combustion efficiency, thereby increasing the output and reducing the exhaust gas, purifying the internal combustion engine and the catalyst, and using the electric power used for the heater coil. The purpose is to provide a device that can reduce fuel consumption by reducing the load on the vehicle.

[0005]

[Means for Solving the Problems]

 As shown in FIG. 1, the means for solving the problems according to the present invention arranges an electric heater coil A so as to hit the injected fuel in the injection passage 1 immediately after the fuel injector provided in each cylinder of the multi-point type electronic fuel injection type gasoline engine. In order to change the resistance value of the heater coil A, an accelerator switch C is attached to the accelerator pedal 3 so that the temperature of the heater coil A rises in a high rotation range where fuel is increased. A dedicated battery D is connected to the coil A for its power supply, a solar panel E is connected to charge it, and a first voltage sensor H is connected in the middle of its wiring to prevent overcharging. For this purpose, a second voltage sensor G was connected between the vehicle battery 4 and the dedicated battery D, and the accelerator pedal 3 was released by the accelerator switch C. Only those configured to charge a dedicated battery D.

[0006]

[Action]

 In the above means for solving the problem, since the electric heater coil A is attached, the key switch 2 activates the 25A relay B during engine startup to generate heat by energization. Then, the resistance value of the heater coil A is changed by the accelerator switch C attached to the accelerator pedal 3, and the accelerator switch C is turned on to raise the temperature of the heater coil A in a high rotation range where the amount of fuel is increased.

Since a dedicated battery D is attached to the power source and a solar panel E is attached to the roof portion of the vehicle for charging the vehicle, the vehicle battery 4 is exclusively used when the charging is stopped and the voltage drops at night or when it is cloudy. Charge Battery D.

At the time of high rotation, the accelerator switch C halves the resistance value to double the current and increase the jule heat.

[0009]

【Example】

 An embodiment of the present invention will now be described with reference to FIG. 1. This device hits the injected fuel in the injection passage 1 immediately after the fuel injector provided in each cylinder of the multipoint type electronic fuel injection type gasoline engine. In order to change the resistance value of the Nikkrum wire electric heater coil A with a wire diameter of 1.3 mm or more, which has a high heat retention property, and attach the accelerator switch C to the accelerator pedal 3 in order to change the resistance value of the heater coil A, The temperature of the heater coil A is configured to rise in a high rotation range where the amount of fuel is increased.

A dedicated battery D is connected to the heater coil A for its power supply, a solar panel (photoelectric conversion element group) E is connected to the roof of the vehicle for charging, and overcharging is performed in the middle of the wiring. To prevent this, a commercially available first voltage sensor H and a backflow prevention element (diode) I are connected, and a second voltage sensor G is connected to the vehicle battery 4 and a dedicated battery D for nighttime or insufficient cloudy charging. The battery is connected between the two, and only when the accelerator pedal 3 is released by the accelerator switch C, the relay is operated to completely connect and charge the dedicated battery D 1.

As described above, the nichrome wire A1 for resistance is provided between the intake pipe and the gasoline engine in the fuel injection passage 1 immediately after the fuel injector provided in each cylinder of the multi-point electronic fuel injection type gasoline engine. Since the electric heater coil A consisting of A8 is attached, this activates the 25A relay B by the key switch 2 while the engine is starting to generate heat by energizing. Then, the resistance value of the heater coil A is changed by the accelerator switch C attached to the accelerator pedal 3, and the accelerator switch C is turned on to raise the temperature of the heater coil A in a high rotation range where the fuel is increased.

Since a dedicated battery D is attached to the power source and a solar panel (photoelectric conversion element group) E is attached to the roof portion of the vehicle to charge the battery, charging is stopped at night or when it is cloudy and the voltage drops. Sometimes, the second voltage sensor G and the 60A relay F that is operated by the accelerator switch C when the accelerator pedal 3 is released are connected to the vehicle battery 4 to charge the dedicated battery D.

The nichrome wires A1 to A8 are coils of a 1600 cc 4-cylinder car having a wire diameter of 1.3 mm and an inner diameter of 4 mm, and have a resistance value of 2 Ω and 6 amps at 12 V. With a resistance value of 1 Ω, 12 amperes are passed to increase Joule heat. Then, the second voltage sensor G is energized when the voltage becomes 12 volts or less.

The solar panel E uses a 20V6A, a backflow prevention element (diode) I is attached to prevent backflow from the dedicated battery D, and overcharge prevention is provided between the solar panel E and the dedicated battery D. For this reason, the first voltage sensor H is attached for this purpose, so that it is cut off when the voltage exceeds 14.7 volts.

With the above structure, knocking is reduced due to high temperature gasification and atomization, and the ignition timing of the vehicle is advanced by 5 to 10 degrees in order to further accelerate combustion.

In an actual vehicle (Honda Civic 1600 cc, year 2000), the device shown in FIG. 1 was attached and the following effect confirmation test was conducted.

(1) Output improvement effect Achievement speed when traveling rapidly up to 50 km / h from a third gear for 300 m on an uphill road with an angle of 10 degrees 105 km / h before installation 110 km / h after installation (2) Exhaust gas reduction , Engine combustion chamber and catalyst purification effect Before installation Immediately after delivery of new vehicle CO 0% HC 0ppm Before installation (after 4000km running) CO 0.07% HC 46ppm After installation CO 0% HC 0ppm (3) Fuel efficiency improvement effect Before installation 14km / l installation Rear 18 km / l (4) Comfortable driving effect Improved combustion efficiency eliminates exhaust combustion, and the piston moves smoothly without backlash pressure, resulting in a “partial opening” of the accelerator, reducing fatigue and enabling comfortable driving.

(5) High-temperature gasification amplification effect Since a heater coil of a nichrome wire with a wire diameter of 1.3 mm is used, it has excellent heat retention and is suitable for an electronic fuel injection vehicle having a structure of directly injecting gasoline. There is.

Moreover, the temperature due to heat generation is about 340 degrees even when the engine is stopped, and does not reach the spontaneous ignition temperature of gasoline. When idling, the aim is to raise the intake air temperature by around 15 degrees to gasify and atomize.

In order to amplify the gasification, the load of the vehicle alternator, which becomes a resistance, can be reduced by a solar panel or the like.

It should be noted that the present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention.
