In our daily lives, there are a lot of rumors about using cars, some out of ignorance, some out of malice, and some out of misinformation. These rumors may affect our car safety and even damage our car. Today, we will debunk these rumors about using cars, so that you can use your car more at ease and worry-free.
Myth 1: The higher the gasoline, the better.
Many people believe that the higher the grade of gasoline, the better the quality of gasoline and the more beneficial it is to the engine, so they do not hesitate to spend ** to add a high grade of gasoline. Actually, this is a misconception. The marking of gasoline refers to the anti-knock resistance of gasoline, that is, the maximum pressure that gasoline can withstand inside the engine. The higher the grade of gasoline, the stronger the anti-knock resistance of gasoline and the ability to adapt to engines with high compression ratios. However, not all engines require high-grade gasoline. If your engine has a low compression ratio, using high-grade gasoline is not only a waste of money, but it can also lead to carbon deposits in the engine, affecting power and fuel consumption. Therefore, you should choose the appropriate gasoline grade according to the compression ratio of your engine, generally speaking, 92 or 95 gasoline can meet the needs of most models.
Myth 2: The higher the tire pressure, the more fuel efficient.
Some people believe that the higher the air pressure of the tire, the smaller the ground contact area of the tire, the less friction, and therefore the more fuel-efficient. In fact, this is also a misunderstanding. The air pressure of the tire is an important factor affecting the safety and comfort of the vehicle. High air pressure in tires can reduce the elasticity of tires, reduce the fit of tires to the road surface, affect the handling and braking performance of the vehicle, increase the risk of tire wear and puncture, and also exacerbate the vibration and noise of the vehicle. If the air pressure of the tire is too low, it will cause the tire to deform, increase the frictional heat of the tire, reduce the life of the tire, and increase fuel consumption and emissions. Therefore, you should choose the right tire pressure according to your model and driving conditions, generally speaking, the tire pressure should be 22-2.between 5 bar.
Myth 3: The bigger the air conditioner is, the cooler it gets.
Some people believe that the more low-key the temperature adjustment switch of the air conditioner, the cooler the air conditioner will be, so in the summer, turn the air conditioner to the lowest temperature. In fact, this is also a misunderstanding. The temperature adjustment switch of the air conditioner controls the flow of refrigerant in the air conditioner, not the refrigeration capacity of the air conditioner. The refrigeration capacity of an air conditioner is determined by the compressor of the air conditioner, which is driven by the engine. The more low-key the temperature adjustment switch of the air conditioner, the greater the flow of refrigerant in the air conditioner, and the more frequently the compressor of the air conditioner starts and stops, consuming the power of the engine, increasing fuel consumption and emissions, and accelerating the wear and tear of the air conditioner. So, you should choose the right air conditioning temperature according to your comfort, generally speaking, the air conditioning temperature should be between 24-26 degrees Celsius.
The above are the three car rumors we want to debunk today, I hope you can use your car correctly to make your car life safer, more comfortable and more energy-efficient.
