As an indispensable means of travel in people's daily lives, with the development of the automobile field, their existence is not only called means of transportation, the owner not only becomes their favorite house, but also becomes their own mobile house, decorating their favorite decorations in decoration. Then, for some of their own lives, many car owners in addition to daily care and maintenance, the choice of gasoline is also a topic of concern to car owners. As we all know, cars are consumer goods, but not only the fuel consumption for daily use, but also the body itself. Especially as the engine consumption of the heart of the car, it does not use the load size of the fuel on the engine. The price of fuel was also different. For example, what is the difference between the common no. 92 gasoline and the no. 95 gasoline? The average owner may be concerned about the difference in prices between the two, and the employees of the gas station deal with fuel every day. Their answers show that the owners not only increase their knowledge, but many owners call the pit daddy by his first name.
No. 92 gasoline is No. 95 gasoline, intuitively speaking, if the price of No. 95 gasoline is high, many car owners think that No. 95 gasoline is more pure and powerful. So, I didn't pay a penny. No, the difference between No. 95 gasoline and No. 92 gasoline is that there is no explosion resistance of both, and the base oil is the same. That is to say, the basic main material is the same, but no raw materials are used, and the additives used in the blending are different. Regarding the composition of No. 95 gasoline and No. 92 gasoline, many people believe that they have found a difference in the names of the two. A 92 and a 95. Yes, the biggest difference in the composition of the two gasolines is the difference in octane number. No. 92 gasoline consists of 8% n-heptane and 92% isooctane, of which 92% is its name, and the proportion of isooctane in No. 95 gasoline is 95%. The price of the two is caused by the difference in octane number, how do these different octane content work?
Octane number and its composition, many car owners know that the mixture in the cylinder of the car engine may not burn completely. For example, in the normal state of the cylinder gasoline combustion generated by the flame propagation speed of 10m/s ~ 20m / s, the flame speed of the cylinder is 1500m / s ~ 2000m / s. When a person runs, his physical function can only jog at a certain distance, but he suddenly chooses to accelerate the sprint, which will overload his body and cause damage. Similarly, the generation of explosive cartridges will certainly increase the load on the engine and reduce the life of the engine. Octane number is an indicator to test the performance of the car, the main role is to determine the explosion resistance of the car. Among them, the role of isooctane is to reduce the situation of engine puncture, the higher the engine pressure during the use of the car, the higher the isooctane content in gasoline, the more fully the gasoline combustion, the probability of tire burst is reduced, to ensure the performance of the car. Therefore, No. 95 gasoline is not only better than No. 92 gasoline explosion resistance, but also during the operation of the engine, gasoline burns more fully. Of course, the price will also be a little higher. After all, the performance of the item is placed there, and the price will naturally be a little high.
How to judge what kind of label gasoline the vehicle should add, many car owners are very clear about what label gasoline should be added to the vehicle. After all, there are instructions for everything you buy. The simplest is to look at the manufacturer's instructions. Second, many items themselves have explanatory markings. As I said earlier, you can open the fuel port of the car yourself and see the recommended logo. Of course, some people say that gasoline that exists in this vehicle is more than recommended, and some people say that an engine with a high compression ratio will have a higher symbol than the common problem about engine compression ratio. Of course, the words are not rude, but there is nothing but everything. In addition to the compression ratio, the type of engine and the technology used should also be considered. So the manufacturer recommends No. 92 gasoline and chooses No. 95 gasoline by himself, is there any improvement to the car? Need to add a higher number of gasoline? There's not really that need to be. The so-called lift is also not high. Of course, there are a few models that originally added No. 92 gasoline, and if they chose No. 95 gasoline, there were also a few models that rose significantly.
In fact, you don't have to worry too much about whether or not to add a higher symbol of gasoline. Manufacturers recommend 92 gasoline, which means your vehicle is less state-of-the-art and the engine ECU may not be recognizable. The ignition advance angle and other parameters will also follow the original recommended gasoline standards, and gasoline with better symbols will not work. Moreover, the average no. 95 gasoline is about 0.4 yuan higher than that of no. 92 gasoline, and even if the amount is small, nothing can be seen. 40 yuan for 100 liters. The annual cost of gasoline costs more money. As the saying goes, it's best to get together. Regarding the label of gasoline, in fact, high label is not necessarily better than low label. The reason why I say this is because it determines the type of gasoline that the engine of which car can withstand. This is the same as people's gastrointestinal tract, because everyone's constitution is different, and the digestive function is also different. Let people who can't eat spicy eat Chongqing hot pot, and he also has to go to gastrointestinal department.
If the form of gasoline is different, it may have the opposite effect, not only can not improve the performance of the car, but also the car's engine will accumulate carbon, may damage the engine.
