What is the density of gasoline?
Depending on the seasonal climate, the density of gasoline will vary slightly, the average is as follows: the average density of No. 90 gasoline is 0.72g/ml; The density of No. 93 gasoline is 0.725g/ml; The density of No. 97 gasoline is 0.737g/ml.
How many pounds is a liter of gasoline?
Liters are volume, volume, and kilograms are weight. A liter =1000ml each of the above density multiplied by 1000 and converted to kg, a liter of 90 gasoline is 0.72 kg; A liter of No. 93 gasoline is 0.725 kg; A litre of 97 gasoline is 0.737 kg. 1 kg (kg)=2 catties a litre of 90 gasoline is 1.44 catties; A liter of 93 gasoline is 1.45 pounds; A litre of 97 gasoline is 1.474 pounds.
How many liters are there in a ton of gasoline?
The average density of No. 90 gasoline is 0.72g/ml; 1000kg/0.722=1385 L; The density of No. 93 gasoline is 0.725g/ml; 1000kg/0.725=1379 L; The density of No. 97 gasoline is 0.737g/ml; 1000kg/0.735=1360 litres.
What's the difference between 93 and 97?
The difference between No. 97 gasoline and No. 93 gasoline is the octane number, No. 97 unleaded gasoline has a higher octane number, which is not easy to cause detachable phenomenon, and high octane gasoline is generally suitable for high compression ratio engines. If your car manufacturer requires the addition of No. 97 gasoline, then it is recommended that you do not use low-grade gasoline to avoid knocking.
The fuel label is the volume percentage of isooctane contained in the fuel. The higher the value, the better the anti-knock property of the fuel. In general, if the compression ratio is below 9.0, you can use No. 93 gasoline, if the compression ratio is greater than 9.0, you need to use No. 97 gasoline, and if it is larger, you need to use No. 98 fuel. The back of your car's fuel tank cap will be marked with the fuel number you need to add, you will know.
9793 indicates the anti-knock of gasoline, the larger the number, the better the anti-knock, suitable for higher compression ratio of the engine, what brand of gasoline your car should choose according to the recommended brand of the manual.
Is it okay to switch from a 93 to a 97?
At first, it was 93 gasoline, and 97 gasoline was added in the middle for about 3 years, and now I want to change back to 93 gasoline, is it OK? Will it damage the engine?
1) It can be yes, but the compression ratio of the car engine with 93 is not large enough, burning 97 is wasted.
2) Can add 93, compression ratio 10.1 with more than 93. Domestic 97, that's 93 with additives, 95 at most. The compression ratio is not enough, plus 97, the combustion is incomplete, easy to deposit carbon, affecting the power. It's better to use 93, it's not about money!!
3) It does not have much adverse effect on the car and the engine itself, but because the design compression ratio is not high enough, it can not make full use of the characteristics of 97 gasoline, which can only be said to be a little waste. There would be no harm in switching back to 93 and no special treatment required. Because the engine is designed to use a compression ratio of 93 gasoline.
What is the relationship between the vehicle compression ratio and the gasoline label?
When buying a car, the car will be marked on the factory manual compression ratio! Many people think that the higher the compression ratio, the more high-grade gasoline should be used! However, with the current engine technology, it can be said that the compression ratio of the car has no relationship with the gasoline label of the car! Turbocharged and Atkinson cycle engines are proof of that!
This is actually a very systematic problem, and I will not talk about it here.
Therefore, the vehicle uses the gasoline label, only according to the requirements of the manufacturer, absolutely no problem!
What is the effect of raising the gasoline label
To be honest, it doesn't work! According to the manufacturer, this car runs on 93 gasoline! You don't have to add 97. Think it is good for the car, but it is a waste of money! Because we have just said that the gasoline label is different, that is, the antiknock is different, there is no other difference!
