Many people often encounter some small questions,
Obviously the fuel tank is only 50 liters,
When the tank is filled with fuel, it shows that 55 liters have been added?
Why is the actual fuel volume larger than the rated capacity?
What should I do if I encounter a refueling dispute?
Let's take a look at the answer
The Municipal Market Supervision Bureau has selected 12 common car fuel tanks on the market for special testing, and the test results show that:
The fuel tank with a nominal volume of 50L is actually 57.25L
The fuel tank with a nominal volume of 55L is actually 60.79L
The tank with a nominal volume of 72.5L is actually refueled at 77.5L
In the end, most of the 12 tanks actually had a capacity of 10% or more than their rated capacity.
What is the reason for this?
The rated capacity ≠ the actual capacity
According to the national mandatory standard "Safety Performance Requirements and Experimental Methods for Automotive Fuel Tanks and Their Installation", the rated capacity of automotive fuel tanks should be controlled at 95% of the maximum liquid capacity. Therefore, automakers generally reserve 5%-10% of the capacity space for the fuel tank. For example, for a 50-liter fuel tank, the actual refueling may go to 55 liters or more.
This is also for safety considerations, because gasoline is a volatile liquid, if the fuel tank is too full, in the process of driving, gasoline in the heat expansion, overflow tank, easy to cause safety accidents.
In addition, the car fuel tank is only a container, not a measuring instrument, and its actual capacity will change under different temperatures and different tank pressures. Therefore, it is unscientific to judge whether the measurement of the tanker is accurate according to the rated volume of the fuel tank.
What should I do if I encounter a refueling dispute?
The first trick is to view
Take a look at the verification mark. This is the market supervision department of the refueling machine after the verification of the qualified, paste it, pay attention to check whether this logo is within the validity period.
Two look at the display. Check whether it is zeroed before refueling, and verify the amount and amount of refueling after refueling.
Three look at the lead seal. The lead seal is like a seal on the test paper bag, which is marked by the dispenser when it leaves the factory or after the market supervision department has verified it. If the lead seal has traces of unpacking, it means that the tanker is likely to be passive. Consumers can call the complaint and report telephone number and ask the verification personnel or supervisors to view the lead seal.
Second trick review
Each gas station is required to be equipped with a standard metering tank, and consumers can ask the gas station staff to review it on site if they have any doubts.
The state stipulates that the maximum allowable error of the dispenser is three thousandths of plus or minus, for example, adding 50 liters of oil, the corresponding maximum allowable error is 0.15 liters, if the review exceeds this range, then pay attention!
The third trick is to ask for help
In case of refueling disputes, you can call 12345 for help. However, before this, it is necessary to retain good evidence: including refueling receipts, taking photos or taking videos, and using practical actions to protect their legitimate rights and interests.
