It relates to a tail pipe condensate generation prevention device.

In general, the exhaust system of a vehicle refers to a device for smoothly discharging exhaust gas generated after burning fuel in each cylinder of an engine to generate power of the vehicle to the outside atmosphere.

A conventional exhaust device is connected to an engine as shown in FIG. 1, and includes an exhaust manifold 1 which collects combustion gas of a cylinder, and is installed on one part of the exhaust manifold 1 so that harmful substances in the exhaust gas are harmless. A catalytic converter (2) for oxidizing and reducing material, and connected to one portion of the catalytic converter (2) to release the exhaust gas from the exhaust manifold (1) and to dissipate some of the heat generated from the exhaust gas. An exhaust pipe 3 connected to one end of the exhaust pipe 3, a muffler 4 for lowering the temperature and pressure of the exhaust gas to attenuate exhaust noise, and an outlet side of the muffler 4; And a tail pipe 5 for guiding the exhaust gas to the outside.

At this time, during cold idling, condensed water is generated inside the tail pipe 5 due to a difference between an exhaust gas temperature and a tail pipe external surface temperature, and the condensed water is generated and discharged by incomplete combustion during combustion of the engine. Combining with the soot (SOOT) is a black condensed water is discharged to the outside has caused a problem that spoil the aesthetics of the parked ground.

The present invention has been made to solve the above problems, and its object is to prevent the generation of condensate by raising the surface temperature of the tail pipe for guiding the discharge of the exhaust gas by combining the condensate with the soot. The present invention provides a tailpipe condensate generation preventing device that prevents black condensate from being generated and discharged.

The structure of the tailpipe condensate generation prevention device according to the present invention for achieving the above object is a hanger for fixing the muffler provided with a tailpipe at the exit side to the lower part of the vehicle, and is installed in the hanger and the current by the vibration of the hanger It comprises a piezoelectric element for generating a, a heating wire wound around the tail pipe and installed to increase the temperature of the tail pipe, and a connection unit connecting the piezoelectric element and the heating wire.

Here, a plurality of the piezoelectric elements are inserted into the hanger.

In addition, the connection unit is made of a wire connected to the piezoelectric element and the connection socket for connecting the wire and the heating wire, one side end of the wire connected to the piezoelectric element is branched into a plurality.

According to the present invention configured as described above, by increasing the surface temperature of the tail pipe to reduce the temperature difference between the inside and the outside of the tail pipe to prevent condensate is generated, black condensate is generated by the combination of the condensate and the soot There is an advantage to prevent the discharge.

Figure 3 is an exploded perspective view showing a piezoelectric element of the tail pipe condensate generation prevention device of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail the tail pipe condensate generation prevention device of the present invention.

Tail pipe condensate generation prevention device of the present invention is to prevent the discharge of the black condensate combined with the soot (SOOT) and the condensate discharged through the exhaust device during cold idle of the vehicle, as shown in Figure 2 A hanger 15 for fixing the muffler 10 provided with a tail pipe 20 to the lower part of the vehicle, and a piezoelectric element 30 provided in the hanger 15 to generate current by vibration of the hanger 15. And a heating wire 40 wound around the tail pipe 20 and installed to increase the temperature of the tail pipe 20, and a connection unit 50 connecting the piezoelectric element 30 and the heating wire 40. It is made, including.

First, the hanger 15 is installed to fix the muffler 10 in the lower portion of the vehicle.

In other words, the hanger 15 is to mount the muffler 10 and the tail pipe 20 installed on the outlet side of the muffler 10 to the lower part of the vehicle, wherein the hanger 15 is made of rubber Preferably, the hanger 15 has a coupling hole (not shown) and a buffer hole (not shown) for coupling the vehicle body and the muffler to be transmitted to the vehicle body in a state in which vibration of the muffler is reduced.

In addition, the piezoelectric element 30 generates electricity by the vibration of the hanger 15.

In other words, the piezoelectric element 30 is installed in the hanger 15 which vibrates by the vibration of the muffler 10, and generates heat by the vibration of the hanger 15, thereby heating the wire 40. To supply electricity.

Here, as illustrated in FIG. 3, a plurality of piezoelectric elements 30 are inserted into the hanger.

That is, by inserting the piezoelectric element 30 into the hanger 15, it is preferable to prevent damage to the piezoelectric element 30 and to provide a plurality of the elements in order to secure the amount of power.

The hot wire 40 is wound around the tail pipe 20 to be installed to increase the temperature of the tail pipe 20.

The tail pipe 20 is installed on the outlet side of the muffler 10 to guide the exhaust gas to the outside, and the tail pipe 20 is connected to the tail pipe 20 by the temperature difference of the exhaust pipe and the surface temperature of the tail pipe 20. Condensate is generated inside, and the black condensate is generated by combining the SOOT and the condensate generated and discharged by incomplete combustion of the engine cylinder.

In other words, the heating wire 40 of the present invention receives electricity from the piezoelectric element 30 to increase the surface temperature of the tail pipe 20 to reduce the temperature difference with the exhaust gas so that condensed water is not generated. This will prevent the production of condensate.

Here, the hot wire 40 is preferably wound in a helix structure, that is, spirally along the outer circumferential surface of the tail pipe 20 to evenly raise the surface temperature of the tail pipe 20 to block generation of condensed water.

In addition, the connection unit 50 is installed to connect the piezoelectric element 30 and the heating wire 40, the wire 51 connected to the piezoelectric element 30 and the wire 51 and the heating wire ( 40 is made of a connecting socket 52 for connecting.

In other words, the wire 51 is a medium for transmitting electricity generated from the piezoelectric element 30 to the heating wire 40, and the connection socket 52 connects the wire 51 and the heating wire 40. To give.

In this case, one side end of the wire 50 connected to the piezoelectric element 30 is branched into a plurality so as to correspond to the number of the piezoelectric elements 30.

Looking again at the tail pipe condensate generation prevention device of the present invention, the black condensate by combining the soot (SOOT) discharged during cold idle of the vehicle, the exhaust gas temperature and the condensate generated by the surface temperature difference of the tail pipe (20) To prevent harming the aesthetics of the parked and discharged ground, the piezoelectric element 30 is installed in a hanger 15 installed to fix the muffler 10 to the lower part of the vehicle, and the muffler 10 Vibration, that is, electricity generated by the vibration of the piezoelectric element 30 is transferred to the hot wire wound along the outer circumferential surface of the tail pipe 20, thereby reducing the temperature difference between the inside and the outside of the tail pipe 20 to generate condensed water. To prevent it.

That is, black condensate is not generated because no condensate is generated.

On the other hand, the tail pipe condensate generation preventing device according to the present invention has been described with reference to the specific embodiments and the accompanying drawings as described above, which can be easily carried out by those skilled in the art to which the present invention pertains. It is intended to be described in detail as much as possible, which does not mean that the technical spirit and scope of the present invention are limited.
