How many years can a car battery with auto start-stop generally last?

Under normal circumstances, the service life of an auto start-stop battery is around 3-4 years. Symptoms of a damaged car battery are as follows: 1. Starting: The most noticeable phenomenon is the feedback when starting the car. If starting becomes very difficult, it is largely due to battery aging. However, there are many other factors that can cause starting difficulties, such as severe carbon buildup and abnormal spark plugs, so it is necessary to consider other conditions as well. 2. Horn: If the car has difficulty starting and the horn is not as loud as before, it is likely that the battery has aged and needs to be replaced promptly. Additionally, the car's headlights will be affected to some extent, causing them to dim. 3. Battery warning light: Another symptom is the battery warning light, which is the most intuitive indicator. This warning light specifically reflects whether there is an issue with the battery. When the battery warning light comes on, it indicates an abnormality, and it is necessary to promptly visit an auto repair shop for inspection.

What Causes Vehicle Body Vibration at Speeds of 80 to 100?

Vehicle body vibration at speeds of 80 to 100 is often caused by severe engine carbon deposits or similar issues. Severe Engine Carbon Deposits: Severe engine carbon deposits are one of the most common reasons for vehicle vibration, typically due to excessive carbon buildup in the fuel injectors or a dirty throttle body. Excessive carbon deposits inside the engine can absorb the gasoline sprayed during cold starts, leading to an overly lean air-fuel mixture and difficulty starting. Users should clean the fuel system and check the idle control valve for carbon buildup, which should be cleaned if necessary. Ignition System Issues: Ignition system problems can also cause such symptoms. It is advisable to inspect the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or improper spark plug firing can lead to these issues. Check if the spark plugs are excessively carbon-fouled and replace them if necessary.

What Causes Car Tires to Become Hot to the Touch?

The reason car tires may become hot to the touch could be due to the vehicle traveling at high speeds, which increases the heat generated during braking, leading to a rise in tire temperature. Overview of Vehicle Speed: Vehicle speed refers to the distance a car travels per unit of time, commonly referred to as speed, with units typically expressed in kilometers per hour or meters per second. Vehicle speed is one of the three key parameters used to describe traffic flow and holds significant importance in traffic flow theory research. Classification of Vehicle Speed: Vehicle speed can also broadly refer to motor vehicle speed. To accommodate different applications, vehicle speed is mainly categorized into spot speed, running speed, and design speed. Spot speed is the instantaneous speed of a vehicle passing a specific point on the road. Design speed is the speed established to determine the design indicators of various geometric elements of a road and ensure their coordination.

What Should Be Noted When Driving on Mountain Roads?

Mountain roads have complex conditions and are high-risk areas for traffic accidents, requiring extra attention. Here are some precautions for driving on mountain roads: Use lower gears when going uphill: When driving on mountain roads, you will inevitably encounter uphill sections. For manual transmission vehicles, it is important to use lower gears when going uphill, as this allows the engine to deliver maximum torque more effectively, making the climb easier. Automatic transmission vehicles can also be shifted into manual mode. Maintain speed and distance when driving on mountain roads: When driving on mountain roads, due to poor visibility around curves, avoid driving too fast. Drive slowly and maintain a safe distance from the vehicle ahead. Also, be aware of animals that might suddenly dart onto the road. Avoid swerving blindly, as this can easily lead to a rollover or falling off a cliff. If you cannot avoid a collision, it is better to hit the obstacle than to risk a fatal accident.

Where is the Front of the Car Located?

It depends on the situation. Here are methods to identify the position of the front of the car under different circumstances: If there is a car in front: When you see the front of your car approaching the lower edge of the front car's bumper from the driver's seat, it means the front of your car is about two meters away from the front car; if you see the upper edge of the front car's bumper, it means the front of your car is 0.5 meters away from the front car. If you are driving an SUV: Using the same two reference points, seeing the lower edge of the bumper from the driver's seat indicates the front of your car is 1.2 meters away from the front car, while seeing the upper edge means the front of your car is 0.3 meters away. To judge the distance of the wheels, if the driver sees the road surface aligned with the protruding point of the right wiper blade from inside the car, it means the tire is on the line.

Is It Dangerous If the Car's Oil Dipstick Doesn't Touch Oil?

It is dangerous if the car's oil dipstick doesn't touch oil. This indicates that the oil level is too low, and it needs to be replenished promptly; otherwise, it may cause severe engine damage. Overview of Engine Oil: Engine oil, also known as engine lubricant (English name: Engine-oil), serves multiple functions for the engine, including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. Composition of Engine Oil: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties. Additives are used to compensate for and improve any deficiencies in the base oil's performance, as well as to provide certain new characteristics, making them an essential part of lubricants.
