Does normal gas station still rely on to jump gun hijack? !
Does accident of gasoline tank 50L encounter gas station forcibly " Yun Zengrong " ? !
Obviously does gas station have room not to allow to cheer however? !

Who does 1. big car abdomen, 45 litres of gasoline tank added 52 litres of oil
Indicate the gasoline tank of 50 litres of capacities holds below 55 litres of oil really likely, this is not cheer machine gave an issue.
The car leaves factory the gasoline tank capacity that gives out on the manual, those who point to is " gasoline tank nominal capacity " , namely " safe capacity " , is not to point to what oil tastes gasoline tank can be full-dress " most high capacity " , its can be measured to cheering only accurate have referenced effect. Wait for a problem to prevent occurrence excessive oil, according to national regulation, the car lights the capacity of gasoline tank demarcate, cannot exceed actual most 95% of high capacity, it is normally most the 80%-90% of high capacity, this means every gasoline tank to be able to be added at least more than gasoline tank capacity the benzine of 5% . Accordingly, in cheer actually be in especially " add full " below condition, cheer a quantity to may be more than capacity of gasoline tank norm.
How does 2. cheer a quantity to be opposite with oily watch on?
Of fat face height and gasoline tank putting oily amount actually is not simple linear relation. After a car that adds full oil was using in case for some time, fat face height dropped inside gasoline tank two, carburettor float also fell subsequently two, behaving oil is index also fell on the watch two, but because gasoline tank appearance is irregular, actually the car drained the oil of more than half.
Why so say? Because general gasoline tank issues half cubage to compare on half a lot of smaller, so although carburettor float is in gasoline tank 1/2 place, but the fuel that actually gasoline tank remains has been not worth a half. And car advocate people because be expressed by oil misdirect, often think to remnant is returned in gasoline tank the oil of two. This also is why normally oily watch finger passes half hind the reason that can drop more quickly.
3. " jump grab " be to be in " hijack " ?
Like the first problem, about " jump gun " discuss to often also see all networks. When cheering, when we often see the member that cheer operates oil gun " loosen closely " , to this, partial car advocate distrustful gas station has " hijack " behavior.
Actually, "Jump gun " it is a kind of normal phenomenon. Cheer machine is automatic jump stop and be not manual control, as direct as size of the vapour lock inside the gasoline tank structure, gasoline tank when cheering relevant. Adding interior of oil gun mouth to one is called the inductor of self-given device, inductor is controlling the open that cheers a gun, the oil in the gasoline tank when preventing to cheer is brimmed over with.
When cheering, oil gun has pressure, oily meeting upgrade is returned, taste when oil should spill over or air is fast when eduction, meet this induction device, cheer a gun to be shut automatically, generation " jump gun " . "Jump gun " the phenomenon is returned and air temperature, cheer speed to concern, air temperature is high, the oily press press in gasoline tank is big, cheer speed too fast, pressure also can increase, the oil in such gasoline tank is splashed easily case, "Jump gun " frequency is tall also.
As long as " jump gun " oil gun won't open, metric stopwatch won't run metric, accordingly " jump gun " won't cause be short of jin little the result of two.
Why cannot be 4. cheered when is discharge oily?
Everybody encounters this kind of situation via regular meeting when gas station is cheered, some cars advocate can not understand, but this time cannot be saved really. As a result of the brunt of discharge oil, bring about deposit to be in of coal tub bottom sundry grain in suspension in oil, if be cheered immediately right now, grain also can enter car gasoline tank subsequently, affect oil to taste character thereby. According to the regulation, it is to cannot offer those who cheer a service when discharge is oily.
Discharge is over after oil, the firm oil that still needs to have proper time period, this paragraph of time also does not suggest the car is cheered. Because this best discharge oil ends and firm oil is cheered again after 15 minutes.
Is 5. morning and evening cheered more be to one's profit?
This gossip is transmitted extensively, because be in the ordinary person's concept,be, heat bilges cold shrink apply to aught, benzine is not exceptional also. Temperature is so high by day, temperature is low in the evening, same price can add more oil in the late evening.
A lot of friends think this is common sense, believe, actually oversight a bit more important: Gas station benzine stores in underground, not easy generation enrages lukewarm acuteness wave motion inside certain period, basic it is constant temperature condition, those think to be cheered in the evening cheer than by day more the friend of be economical, affirmative meeting is disappointed.
How much does 6. gasoline tank add appropriate? Add half case every time?
A little attentive friend thinks, after adding full box oil, automobile body weight is increased, raise oily cost in the meeting in travel so. If add half box oil only, reduce weight to also be met more the section is oily.
Actually this Zhang cannot so calculate, the gasoline tank of average car is controlled to 60 litres in 50 litres, the weight of half box oil is 20-30 about kilogram, and of car itself self-prossessed and general exceed a ton, although a person sits to also want to be more than the weight of half box oil far more on the car, the cost next to nothing that its add. Still do not have a consideration to add half box oil to still can increase what is more,the rather that more run the frequency of gas station, will look from this " add half box oil fuller than adding oil should save oil " this thing, do not have necessary kink completely.
Does 7. oil taste color and quality to there is immediate concern?
Oily craft of the property of tasted chroma and crude oil, treatment, purificatory deepness is concerned. Refine factory treatment technology is different, different, oil tastes color to be able to differ somewhat, with oily character the quantity does not have immediate impact.
Color is tasted to was not limitted clearly to oil in national level. Pure rely on color to judge oily quality the amount is acceptable not scientific. If be 0 eligible derv likewise, because crude oil origin is different, produce the refinery that differs oneself, refine technology is different, the color that oil tastes is different.
The manufacturing facilities that is like state-owned and large refinery and manufacturing technology are more advanced, purificatory deepness is tall, the 0 derv facial expression that production gives is shown flaxen, and the manufacturing facilities of small-sized refinery mixes the place manufacturing technology is not quite advanced, wash out deepness is insufficient, the 0 derv facial expression that production gives shows deep yellow. Above oil is tasted is eligible product, there just is difference on color, do not affect performance characteristics.
For example Hong Kong " red oil " , it is not Hong Kong production, imports and exports is duty-free, basically supply haven ship to use, add orchil in order to distinguish at civil derv.
8. alcohol benzine meeting caustic car?
The car uses alcohol gas is the gasoline fuel that a kind of accretion that uses for car has 10% fuel alcohol. Compare with common benzine photograph, the contains 10% fuel alcohol alcohol gas of identical bulk, the CO that can make car tail gas medium decreases 45% , CH decreases 35% . Restrain to reducing air pollution to reach " greenhouse effect " the sense is great.
Alcohol benzine won't be caused to car damage. Although its and common benzine are in hydrophily, caustic wait for a respect to have truly different, but executive level of alcohol gas production and common benzine standard have consistency, use it and won't cause to car damage.
Use alcohol benzine is OK better land reduces car loss, above all, alcohol benzine octane number is higher, can promote fuel quality; Additional, alcohol benzine combustion is complete, can reduce what what common benzine combustion forms not completely to accumulate carbolic phenomenon. The fuel alcohol that joins in alcohol benzine is the organic dissolvent with a kind of good performance, precipitate and condense of impurity of the fuel in eliminating car gasoline tank and fuel supply system effectively, have effect of favorable oil path dredge. In charge respect, alcohol benzine and common benzine comparative.
Do all cars add 9. is the oil of higher grade better?
The discretion of benzine grade basically is the volume that shows benzine octane number, do not spend on behalf of petrolic cleanness. Octane number is a numerical value that represents capacity of combustion of benzine antiknock shake, taller anti-knock properties is better. The car adds the oil of what grade, the compression ratio of engine said to calculate. Engine compression ratio and recommend use benzine tab to be able to be checked in explaining along with the car.
Generally speaking, the demand gas grade with older compression ratio is higher, the car with small compression ratio should use low grade gas. If the car of low compression ratio added high grade oil, can cause inflammation inadequate, cannot produce the power of engine adequately. Not only wasted fuel for nothing, let engine generation easily still accumulate carbon; If high pressure shrank to add low grade oil than the car, high-grade car uses low grade oil, explode generation shake, cause car power to drop, oily bad news is elevatory, discharge aggravation, create piston, cylinder body possibly also inside unusual wear away, pull a crock, engine loss of life.
Is 10. used " fuel treasure " after all good?
Common of fuel additive, kosher agent says " fuel treasure " . The experiment proves, "Fuel treasure " taste the kosher function with have particular with oil to the car, what can hold engine cylinder body at the same time is clean, prevent and the carbon deposit inside clear tonsorial intention, reduce oily cost on certain level thereby, prolong engine service life. Kosher agent product also can have some fuel special function, increase for example lubricant degree, content of the grain in reducing tail gas to discharge and a few ill other people.
But, should notice at the same time, all fuel are not on the market at present the cognizance that kosher agent product passes relevant section; Next, shoddy sham fuel is kosher the agent is flush. The effect that these two kinds of circumstances cause product of a few brands is not distinct, because do not contain active ingredient,return even, have the possibility of attaint engine. This also is on the net a few cards express " fuel treasure is be unworthy of the name or the title, harmful to car engine " and by the reason of a large number of transmit. Everybody ought to according to car actual condition, buy eligible product through normal channel.
