Description

When automobiles, vehicles, etc. are traveling other than at low speeds, eddy and eddy currents are generated in the rear part under the floor. While rectifying these to reduce running resistance and at the same time generating negative pressure on the underside of the car body to prevent the rear part of the car body from rising and stabilizing running, the exhaust of the self-equipped engine is guided into the device to cool and exhaust. The volume is reduced, the explosion noise is reduced, and the noise is reduced, and the negative pressure generated on the lower surface of the device is used to suck and discharge the exhaust from the rear end of the device to promote exhaust and reduce fuel consumption. ..

When the vehicle runs at medium and high speeds, eddy and eddy currents are generated under the floor. According to the present invention, running resistance can be reduced by rectifying this. At the same time, a negative pressure was generated on the lower surface of the device at medium and high speeds to prevent the rear wheels from floating and to stabilize driving.

In addition, while trying to reduce and mute the explosion of the self-equipped engine, the exhaust is guided into the device, cooled to reduce the volume, promote it, and save fuel. Previously, there were similar ones to the present invention, but these had nothing to do with the reduction of fuel consumption, and only generated negative pressure on the lower surface of the device to prevent the rear part of the vehicle body from rising and to stabilize high-speed running. On the other hand, the present invention generates a negative pressure on the lower surface of the device to stabilize high-speed running.

This is a new technology that improves fuel efficiency and reduces fuel consumption by sucking and discharging exhaust and cooled outside air using the negative pressure generated on the underside of the device during driving.

The conventional muffler for vehicles only reduced the sound of the self-equipped engine, and had no effect of reducing back pressure, but rather increased the exhaust resistance. Further, when an automobile, a vehicle, or the like travels, eddy or overflow occurs under the floor behind the vehicle. The faster it gets, the more it increases. By rectifying this underfloor eddy and eddy current, running resistance is reduced.

The present invention aims at rectification and at the same time generates a negative pressure on the lower surface of the device mounted under the floor on the ground side at high speed to prevent the rear wheels from floating and to stabilize the running.
