Event Review: Refueling Doubts Exceeding Labeled Capacity

It is reported that the owner's lover added gas twice at the gas station on the same day. "My 28-litre tank was not filled with 23.28 litres for the first time, and 18.45 litres for the second time added up to 41.73 litres! This is definitely not right!" The car owner asked the market supervision bureau to intervene on the spot.

incident, the staff of the local market supervision bureau inspected the equipment of the gas station and found that the lead seal of the tanker was intact and the inspection mark was also there, proving that there was no problem with the tanker.

in order to find out how much oil is in the fuel tank of this car, the two sides agreed to go to the 4S store for on-site verification, draw out all the oil in the fuel tank of the car and then measure it. Under the witness of everyone, the staff used professional instruments to pump oil, and as a result, 43 liters of gasoline were drawn from the car's fuel tank!

himself was convinced by the result and did not have any objection, and then released a solemn apology video on his social platform.

Professional Interpretation: Tank Capacity & ne; Actual Capacity

why is it that the tank is clearly marked with a capacity of 28 liters, but it can be filled with more oil? in fact, this is because the capacity marked on the tank & ne; the maximum capacity of the tank.

According to Sinopec Science, the capacity marked on the fuel tank is "safe capacity", also known as the rated volume of the fuel tank. The state has stipulated that "the rated volume of the automobile fuel tank should be controlled at 95% of the maximum capacity of the fuel tank", that is, the actual capacity of the fuel tank should be at least 5% larger than its rated volume.

has such a regulation is that the fuel tank is designed taking into account the characteristics of thermal expansion and contraction of fuel. In order to ensure driving safety, after the car is refueled and added to the rated volume, a certain safety space must be left in the fuel tank.

metrological verification agency has randomly selected 10 models for testing and found that the actual capacity of various types of automobile fuel tanks is at least 5% larger than that marked on the fuel tanks, and some have reached 10%.

In addition, the automobile fuel tank is only a container, not a measuring instrument. Its actual capacity will change under different temperatures and different pressures in the tank. Therefore, it is unscientific to judge whether the measurement of the tanker is accurate according to the rated volume of the fuel tank.

Traditional Lead Seal and Innovation of Intelligent Lead Seal

Although the traditional lead seal proved that the equipment has not been tampered with in this incident, there are obvious shortcomings in its passive supervision mode. If the use of intelligent lead seal, disputes or will be efficient resolution:

1, the whole process of digital management

integrates real-time monitoring, wireless networking and active early warning functions to realize the closed-loop control of the whole link of lead sealing task issuance, execution and traceability, and eliminate human intervention.

2. Consumer self-verification

car owners can check the lead seal status in real time through the matching APP, confirm the safety of the equipment before refueling, give immediate early warning of abnormal situations and synchronize the supervision department.

3, cost reduction and efficiency win-win

Market Supervision Bureau can reduce the frequency of on-site verification and save more than 60% of the supervision cost. Gas stations enhance credibility through technical endorsement and reduce the loss of manpower and time in dispute handling.

industry revelation: intelligent upgrade is imperative

Although the dispute has come to an end, it has sounded the alarm for the industry:

Guarantee business compliance: intelligent lead seal can effectively prevent internal and external illegal tampering behavior, maintain the integrity of the gas station;

Enhance consumer trust: technology transparency can strengthen consumer confidence, shape brand technology image, boost passenger flow growth;

Building a new industry ecology: Through the large-scale application of intelligent supervision equipment, it can promote the establishment of a fair, transparent and efficient refueling consumption environment.

today, with the digital wave sweeping all fields, the intelligent transformation of the refueling industry is no longer a multiple-choice question, but a must-answer question. Only by embracing technological innovation can we achieve the double improvement of regulatory efficiency and user experience, making every refueling a safe choice.
