With development of economy, cars have become a necessary means of transportation in our modern society. More and more people have their own cars, but they always hear people say that if you can afford a car, you can't maintain it. When starting a car, especially when using vehicle fuel, many people think about how to spend least amount of money to fill up more fuel. Many drivers choose to fill up in morning because most of you think that fuel in morning can be a little more, but we do not think so. We learned from staff at gas station that people who really understand cars go to fill up at noon. Why do old drivers always go to fill up at noon? The gas station employee said it was a leak, and car owner: I found out more, let's see.
Many car users choose to fill up in morning or in evening, thinking that they fill up in morning and evening because air temperature is cooler. By principle of thermal expansion and cold contraction, more gasoline will be added and volatility will be slower! So save money! Is it really true? If you also have this mindset, then I think you are also a cute car friend or even a best car friend in physics. In fact, refueling at a gas station has nothing to do with outside temperature. Gasoline at a gas station is cooled underground at a constant temperature. When gas station was built, a special design was made to store gasoline under it. Gasoline does not change temperature of gasoline due to external heating and cooling, therefore, regardless from when you fill up, gasoline that comes out is exactly the same.
At present, many older drivers prefer to fill up at noon. They don't try to save money. This is because there are few people at noon. Staggering during rush hour to refuel can buy you time and speed. refueling at other times, it is very possible to queue. If there are fewer people in queue, it will be very annoying if there are too many people in queue. If you are unfortunate enough to encounter a traffic jam, you will use more fuel between stops and stops, and it will take a long time before refueling is completed, so owner of car should not waste time in morning after learning about such a situation. filling is same.
Finally, when it comes to fuel economy, I will teach you how to save fuel while driving. First, use economical speed. Fuel consumption depends on vehicle speed. Many car owners know this, but you know what speed is best for fuel economy. ?
According to authoritative statistics, at a car speed of 80 km/h, fuel consumption and car speed are best matched, this is so-called economic speed, but it also varies from car to car. .Fast acceleration consumes more than 30% more fuel than slow acceleration. In process of fast acceleration, there is more fuel in combustion chamber and less air, and combustion chamber is in an oxygen-deficient state. They are all used to do work, but produce a lot of waste, which is not only pollutes environment, but also makes engine more fuel intensive. Conversely, when braking quickly, intensity of braking is generally greater, and vehicle must consume more kinetic energy to achieve rapid braking or stopping, re-accelerating or starting - a waste of time and fuel .
