The effects of poor quality gasoline include: 1. Difficulty starting, or even failure to start; 2. Engine shaking at idle after starting; 3. Obvious vehicle vibration; 4. Unpleasant exhaust odor; 5. Valve noise; 6. Weak acceleration and high fuel consumption; 7. Gear shift impact. Methods to test gasoline quality are: 1. Observe the color of the gasoline; 2. Smell the gasoline; 3. Judge by touch. Gasoline has a high octane rating, which is categorized by octane level into: 89, 90, 92, 93, 95, 97, 98. The higher the number, the stronger the gasoline's anti-knock performance.

If the quality of the gasoline you use for your car is too poor, my own experience tells me that it can be really troublesome. The engine becomes particularly weak, sluggish during acceleration, and the car feels like it's gasping for breath. Fuel consumption also skyrockets, and you might end up spending an extra liter or two of gas for every 100 kilometers, which means money flying out of your pocket. Sometimes, the car might even shake for no reason or emit black smoke, and after inspection, it turns out to be carbon buildup clogging the fuel injectors. Over time, this can lead to increased wear on engine components, shortening the car's lifespan. I recommend always using high-quality gasoline and avoiding cheap, small gas stations. Spend a little extra time finding a reputable brand to fill up—it saves you the hassle and expense of frequent repairs. This directly affects your daily driving comfort, and no one wants to drive a car that feels like an old ox pulling a cart—both uncomfortable and dangerous. In short, poor-quality gasoline isn't just a minor issue; it can significantly degrade your car's performance and make driving a nerve-wracking experience.

What National Emission Standards Do IV and V Represent?

The environmental protection standards labeled as National IV (National V) in vehicle parameters indicate that the vehicle complies with two emission standards. Manufacturers produce specific models tailored to different regional requirements. Cities mandating National V standards receive National V compliant models, while those requiring National IV standards are supplied with National IV compliant vehicles. Here is information about the National IV emission standard: 1. The National IV emission standard represents China's fourth-phase motor vehicle pollutant emission regulations. Primary automotive pollutants include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). This standard controls and reduces vehicle emissions below specified thresholds through technologies such as advanced catalytic converter active layers, secondary air injection, and cooled exhaust gas recirculation systems. 2. The "National V" emission standard is equivalent to the Euro V standard, which Europe formally implemented on September 1, 2009.

What does heat/cool mean in a car?

Heat in a car means warming up, which can increase the temperature of the air vents, while COOL represents the cooling mode, which can lower the temperature of the air vents. The car's heat switch is for defogging. The function of this button is generally the rear windshield defogging feature. When pressed, the heating wires on the rear windshield will heat up, removing fog or snow from the rear windshield. Turning on the switch will heat the exterior rearview mirrors and the rear windshield, mainly to prevent frost, defrost, or defog the mirrors, making it easier for the driver to observe the outside conditions. Although the heat switch is very useful in rainy weather, it is not suitable for all occasions. Since heating relies on the rapid warming of the internal heating wires in the glass, if the outside temperature is too low, the rapidly heated glass can easily crack. Therefore, avoid using the rearview mirror and rear window heating functions immediately when temperatures are low in winter. COOL represents the cooling mode. After the air conditioner is powered on, the low-pressure vapor of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure vapor, which is then discharged to the condenser. At the same time, the axial fan draws in outdoor air that flows through the condenser, carrying away the heat released by the refrigerant, causing the high-pressure refrigerant vapor to condense into high-pressure liquid.

What Causes the Steering Wheel to Become Heavier?

There are several reasons why a car's steering wheel may become heavier: 1. For hydraulic power steering, check if the power steering fluid is low or if there is any leakage. If the fluid is low, top it up to the normal range. If the fluid level is normal, check if the power steering pump belt is too loose. If it is, tighten the belt. Also, check if the fluid is too dirty, which can reduce its flowability. Generally, the fluid should be replaced every 2 years or 60,000 kilometers. 2. For electric power steering, check if the fuse is blown and if there are any open circuits or short circuits to ground in the wiring. 3. Check the tire pressure, as low pressure can also make the steering heavier. If the tires are underinflated, inflate them to the recommended pressure.
