Abstract

A nipple device for preventing PCV freezing is provided to be easily installed without additional circuit for supplying electric power to a heating wire, and to easily diagnose defective. A nipple device for preventing PCV freezing includes a nipple installed to a surge tank, a rotating fan installed to an inner circumference of the nipple, a generator(30) installed to be connected to the rotating fan by a rotation shaft(28) to generate electric power, and a heating wire(32) electrically connected to the generator and installed in the nipple. Since the nipple is frozen at the surge tank, the frozen nipple is melted using the heating wire and the electricity when the nipple is frozen at the PCV. In other words, blow-by gas always flows into the surge tank through the nipple of the PCV. At this time, the rotating fan connected to the generator is rotated by the flow of the blow-by gas to generate electricity. When the generator is operated, the heating wire of the nipple received with the electric power is heated.

The present invention relates to a passive teeth freezing nipple device, and more particularly, the freezing of the passive nipple of the surge tank side, which is the source of freezing generation, simply heats the heating wire by electricity generated by rotating the rotating fan by blow-by gas. The passive to prevent the freezing is related to the freezing nipple device.

1 is a view showing a surge tank side passive nipple according to the prior art.

In regions with extreme weather conditions, such as Europe, North America, and China, long-term operation of the engine's ventilation system can result in low temperatures and running winds.

In order to prevent such freezing, heat insulation measures such as application of a thermal pad to a ventilation hose, an engine cover in an engine room, and installation of a hot water line have been taken.

Conventional ventilation system has a problem in that the assembly of the engine is complicated and additional costs are generated by using a thermal insulation measure such as a thermal insulation pad, an engine cover, a hot water line to preserve the heat of the engine.

As a result, a larger engine room design space has to be secured, and thus there is a problem in that there is a defect in which freezing occurs immediately when productivity problems and reliable heat retention cannot be maintained.

In addition, in the anti-icing device using the electric heating wire, a separate circuit for supplying electric power to the nipple heating wire side is inevitable in the case of the device to prevent the freezing by using the heating wire on the nipple side, and the engine with the existing circuit is configured for power supply. There was a problem to configure a separate power supply to the side power or generator.

And the ventilation in the actual vehicle state is blown out by the main valve of the blower side rather than the breather side with the throttle partially opened, and when the freezing occurs, the warm blow-by gas leaked out through the valve of the passive valve (4) When the blow tank 6 side blow-by gas meets the cold intake air 8 introduced through the surge tank side throttle body, freezing occurs in the surge tank side nipple 2 by the water vapor contained in the gas. There was a problem.

At this time, as the longer time passes, the amount of water vapor to be frozen increases, eventually causing the passive line to be blocked, thereby causing a fatal damage such as an explosion due to the expansion of the blow-by gas.

The object of the present invention is to solve the problems of the prior art made as described above. The object of the present invention is to freeze the surge tank side passive nipple, which is the source of freezing, by simply rotating the rotating fan by blow-by gas. The passive that prevents the freezing by heating the hot wire to provide the freezing nipple device.

Other objects and advantages of the invention will be described below and will be appreciated by the embodiments of the invention. Furthermore, the objects and advantages of the present invention can be realized by means and combinations indicated in the claims.

In order to achieve these technical challenges,

A nipple provided on the surge tank side;

A rotating fan installed on the inner circumferential surface of the nipple;

A generator that is connected to the rotating fan by a rotational shaft to generate power;

A hot wire connected to the generator and wired in the nipple; Provided is a passive nipple prevention nipple apparatus characterized in that it comprises a.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

3 is a view showing a passive teeth icing nipple device according to an embodiment of the present invention, Figure 4 is a view showing a passive icing prevention nipple device in Figure 3, Figure 5 is a passive icing in Figure 4 Side sectional drawing which shows the prevention nipple apparatus.

Referring to the drawings, the passive anti-icing nipple device 20 includes a nipple 24 provided on the surge tank 22 side; A rotating fan 26 provided on the inner circumferential surface of the nipple 24; A generator 30 connected to the rotating fan 26 by a rotating shaft 28 and generating power; A hot wire 32 connected to the generator 30 and wired in the nipple 24; It is configured to include.

Referring to the operation of the present invention made as described above, since the nipple 24 is frozen on the surge tank 22 side, using the heating wire 32 and electricity at the time of freezing on the PCV nipple 24 side The ice will be released.

That is, the blow-by gas always flows into the surge tank 22 through the passive nipple 24. At this time, by the flow of the blow-by gas, the rotary fan 26 connected to the generator 30 rotates to generate electricity. The heating wire 32 of the nipple 24 supplied with power by the operation of the generator 30 is heated.

Since the icing of the nipple 24 occurs at the nipple outlet side where the blow-by gas and cold air meet, the heating wire is installed only at the end of the nipple to prevent or thaw using the heat of the electric furnace heating wire generated by the generator.

As described above, the passive is simply installed without a separate circuit configuration for supplying power to the heating wire provided on the nipple side.

And it is easy to check, diagnose and replace when the breakdown of the PC freeze nipple device is broken.

Improved engine reliability due to cold zone freeze protection.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this and is given by the person of ordinary skill in the art to the following, Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
