When refueling at a gas station, it is not only necessary to compare the price difference of gasoline of different types of gasoline, but also to consider the problem that the power will become stronger after changing to No. 95 gasoline. Today I would like to talk to you in particular about whether the replacement of gasoline will affect the power of the car, and what methods can be used to improve the power of the car. Essentially, there is no difference in oil between No. 92 and No. 95 oil. However, the content of the additive is different, and the general additive contains octane number. The octane number is to improve the knock resistance of gasoline.
Many car owners believe that the car with no. 95 oil and no. 98 oil is a relatively high-end car, but most of them use turbocharged engines, or more efficient engines. Some of the internal temperatures and compression ratios in this engine are very high. When the engine is operated under high temperature and high pressure, the knock resistance of gasoline is more demanding. If there is no requirement for knock performance, gasoline is likely to be ignited in advance in this high temperature and high pressure environment. In this case, the engine generally causes knocking, causing a lot of damage to the engine. Especially the cylinders and pistons. Therefore, high-efficiency engines generally require the knock resistance of gasoline, and the more octane numbers added to No. 95 and No. 98 gasoline, the more difficult the gasoline is, and the higher the knock resistance. Therefore, general turbocharged engines require high-label gasoline.
Second, the car label is upward compatible, downward incompatible If the car itself is suitable for adding No. 92 gasoline, in general, even if the gasoline is replaced, the power of the car will not become stronger, and the oil will not become difficult to burn. The No. 92 gasoline in most areas is ethanol gasoline, and if you switch to non-ethanol No. 95 gasoline, the composition of the oil will change, so the power of the car will indeed become stronger. However, if the owner does not need to drive for a long time, but just moves around the city, the actual addition of No. 92 gasoline is not much different from No. 95 gasoline. Since the general engine requires a high temperature and high pressure environment, the addition of No. 95 gasoline may cause gasoline to not ignite easily, or insufficient combustion will lead to an increase in carbon accumulation. Many car owners felt that the engine was quieter than usual after changing to No. 95 gasoline. Some vehicles do have this phenomenon, but engine quietness is not just a good thing. A slight knock can enhance the power of the car and eliminate the accumulation of carbon to a certain extent.
Therefore, replacing gasoline does not necessarily increase the power of the car. Just follow the manufacturer's rules. Car owners need to drive at high speeds frequently, and if the driving style is very intense, changing to No. 95 oil will not have a great impact on the car. In most cars, the car's label is compatible, but if the manufacturer requires the car to add No. 95 gasoline, it cannot add No. 92 gasoline, which is easy to cause a larger knock and damage the engine. Third, what is horsepower on wheels If the label of gasoline and the performance improvement of the car do not have much to do with it, what does it have to do with it? Many car owners have found that the a car of two cars has dozens of horsepower more than the b car, but in terms of power performance, the a car is not better than the b car, in fact, this phenomenon is another angle, we say "cheated by the car factory".
Generally speaking, when the owner buys the vehicle, he sees that the manufacturer gives a lot of horsepower-related parameters and data, how is this horsepower data measured? In fact, most manufacturers do this by placing this engine on a bench and measuring the power of the engine with a generator, and the test standard is different. For example, if the connection load of all engines is lifted and measured in a similarly no-load situation, the final value will be greater. However, to make the car drive on the road, it is completely insufficient to rely on the engine alone, and it also needs the assistance of other parts, so it is also necessary to be related to the horsepower of the wheels, and the horsepower of the wheels can be understood as the horsepower value of the tires working on the ground. In general, the output power of the engine is transmitted to the tire through the clutch, transmission, drive shaft, etc. There are losses in this transmission process, and the biggest loss of power is the transmission.
Since the AT transmission transmits power through the fluid, the loss of power is large. Dual-clutch transmissions have not only one set of clutches, but also two sets. Due to the number advantage, yes, the dual-clutch transmission is more productive, so the transmission efficiency is also higher and the power loss is smaller. The CVT transmission structure is relatively simple, and the efficiency of transmitting power is also very high. These three transmissions have more pros and cons, and the manufacturer's adjustments have a great impact on traditional efficiency. In general, engine plants are marked as 200 horsepower. However, if it reaches the tire, there may only be 180 left. This is the actual power used by the owner in the drive. Just like the fuel consumption marked by the Ministry of Industry and Information Technology, it is generally difficult for car owners to save so much oil, and the horsepower marked by the manufacturer is not fully exerted.
Fourth, the car power-to-weight ratio is not only the horsepower on the wheels, but also the indispensable parameter of the power-to-weight ratio. Many owners may not know much about this parameter, but in fact, the power-to-weight ratio also has the name of push-to-weight ratio. This is the ratio of the maximum power value of the car to the weight of the vehicle, and the larger the calculated ratio, the higher the probability of acceleration. In simple terms, the Kawasaki H2R has a power-to-weight ratio of 1.3 and the Bugatti-Wel W16 has a thrust-to-weight ratio of 0.53. Comparatively speaking, the horsepower of the Kawasaki H2R is 3 times smaller than that of the Weihang W16, but it is far better than the Weihang W16 in the actual H2R.
The Kawasaki H2R has also been joked by many fans: "The H2R doesn't have rearview mirrors, or the car behind it can't catch up." In addition, many owners replace the cast wheels of the original car with forged wheels when carrying out vehicle modifications. The reason is that this part of the owners believe that the forged wheel is more rigid and lighter than the cast wheel, which can improve the power performance of the vehicle to a greater extent. As mentioned above, the dynamic performance of a car is actually related to many factors, but changing the No. 92 gasoline car to the No. 95 gasoline car has a certain effect on the car that needs to drive a long distance and high speed, but to improve the power of the vehicle, it is still necessary to reduce the weight of the entire car
