The arrival of cars has improved the efficiency of our travel and changed the way we live. With the improvement of people's economic level, more and more families have joined the ranks of buying cars. Nowadays, cars have become a necessity for most homes. I will cherish it after buying a new car. After all, the price of a car is very expensive, and many people's annual salary is not enough to buy a car, so the owner cherishes the car. However, many beginner drivers can only drive and actually cannot understand the car. Cars are high-tech products, but there are many things worth noting in driving, such as pre-driving preparations - hot cars. Some car owners have the habit of hot cars, and some car owners do not have the habit of hot cars. Isn't it hot in the morning, does driving like this also have an impact? Repairman: Do you hate that cars break down slowly?
As we all know, there are multiple gauges on the car dashboard, including vehicle speed, engine speed, oil volume and water temperature. These represent different indicators of the operation of the car. The water thermometer is in all cars, and it represents the car fuel tank temperature. The temperature is too low, too high is not enough, most cars have a water temperature between 90-110 degrees. Engines work on fuel, so they can't run without fuel. But the engine is essentially a hot engine and has its own optimal operating temperature. When the optimum temperature is reached, the fuel consumption of the engine is reduced. The temperature of the engine is controlled by a thermostat. If the temperature is low, the thermostat shuts down and the cooling water has only a small circulation. If the temperature is high, it will open a large cycle, and the cooling fan will automatically turn on.
To increase the intake air temperature, there is a refrigerant piping around the throttle valve. The higher the water temperature, the higher the intake air temperature, as well as the higher the temperature of the air and fuel mixture in the cylinder. At this point, the combustion is more complete. Car owners know that driving in the summer is more fuel-intensive than driving in the winter. This is the effect of temperature. After we start the vehicle, the engine goes into idle. As the water temperature rises, the engine speed gradually decreases. However, the operation of the engine has two jobs. On the one hand, it is internal work, on the other hand, it is external work. The internal work is to maintain the normal operation of the engine, and the external work is to start the transmission. So, do you need a sports car before driving? Now there is a saying in the automobile industry that the previous car engine is a carburetor, the temperature is low and it is difficult to atomize, you must heat the car before driving, and now the cars are all EFI, and you can either heat the car or not heat up before driving
In fact, this sentence is not wrong on the surface. In addition, some vehicle manuals do not say that a hot car is needed. Some vehicle manuals use hot cars. However, according to some vehicle manuals, the car cannot drive at high speed when the water temperature is too low. Must be driven at low speeds. This kind of low-speed driving is a hot car process, but the saying is different. On the other hand, the reason why the car needs a hot car is to improve the engine mixture temperature, promote full combustion, improve the lubricating oil temperature of the engine and transmission, reduce the resistance, and is very beneficial to reduce fuel consumption and improve engine life. Therefore, no matter how the car engine technology is improved, the owner should develop the habit of electric vehicles and avoid causing any harm to the car.
