In order to recharge LPG fuel, it was inevitable to visit LPG stations.

However, if the driver travels the vehicle for a long distance and finds no designated LPG charging station even though the LPG fuel charged in the LPG fuel tank is almost exhausted, the driver is forced to tow the vehicle to the LPG charging station because the vehicle cannot be operated anymore. The car was running into a very uncomfortable problem.

Moreover, the installation of LPG charging station to charge LPG fuel in LPG vehicles requires a considerable amount of space and enormous investment costs. Therefore, even if there is demand, construction is limited to limited places such as urban areas considering the frequency of use and economic feasibility. I'm just doing it. Therefore, drivers who travel around the city or rural areas by using LPG vehicles are always concerned about the suspension of fuel due to lack of fuel, thereby neglecting forward attention as an unstable psychological condition such as observing LPG gauge frequently during operation. The case is happening.

The present invention is proposed to solve such a problem, and the driver who operates the LPG vehicle can reserve the fuel according to his own driving plan regardless of the location of the LPG charging station and simply replace and replenish it when necessary. There is a main purpose.

Another object of the present invention is to store and sell LPG fuel regardless of the place where the LPG storage warehouse is installed, so that even if there is no additional construction of the LPG charging station that requires a huge investment in facility cost, It is to ensure that the driver can be supplied with a shortage of fuel at these places to continue safe driving.
