Do Modern Cars No Longer Need Water?

Modern cars do not require water; antifreeze is sufficient. Here are the reasons why cars no longer need water: Water is prone to evaporation: In the early stages of automotive development, engine cooling was indeed achieved using a water circulation system. When the engine temperature rises, water tends to evaporate as the temperature increases. During normal engine operation, continuous water circulation cools the engine. However, over time, the water in the radiator gradually decreases due to evaporation, necessitating frequent refills. Water is prone to boiling: Since water boils at 100°C and the normal operating temperature of an engine ranges between 85-100°C, the water in the radiator can become extremely hot during normal operation. If the engine runs for an extended period or under heavy load, the water in the radiator is likely to boil. Once boiling occurs, it can no longer effectively cool the engine, triggering a high-temperature warning and causing the engine to malfunction, requiring the vehicle to stop and cool down.

What happens if only one side of the toe is adjusted?

Adjusting only one side of the toe will cause a slight change in the steering input shaft, but the amount is generally not significant. Relevant information about toe is as follows: 1. Introduction: Front wheel toe-in refers to the inward angle (negative toe). 2. Front wheel camber: Due to front wheel camber, the left and right wheels frequently experience opposing camber thrust forces corresponding to the camber angle, which increases tire wear. To avoid this situation, it is necessary to eliminate this camber thrust. The solution is to install the wheels in a way that the center planes of the two front wheels are not parallel, with the distance between the front edges of the wheels being smaller than that between the rear edges. This is called front wheel toe-in, which appears as an inward angle when viewed along the direction of the vehicle.

Do new lead-acid batteries need to be fully discharged before charging?

Lead-acid batteries do not need to be fully discharged before charging. Here is the relevant introduction: 1. Suggestion: For the first charge of a new electric vehicle, there is no need to deliberately discharge the battery completely before charging. Lead-acid batteries have no memory effect. It is generally recommended to charge the battery when the remaining capacity is 30% to 40%, which is the optimal time. It is usually not recommended to charge for more than 12 hours. 2. First charge: When charging the battery for the first time, the charger may heat up quickly and reach a high temperature, especially during summer charging. Do not place the charger on objects that are prone to heat or combustion, and it is best not to place it on the seat of the electric vehicle to prevent fire. Many cases of spontaneous combustion of electric vehicles have occurred during charging, so please be very careful.

What is the difference between headlights, high beams, and low beams?

The differences between headlights, high beams, and low beams are as follows: 1. Headlights: By definition, headlights refer to the lighting devices installed on both sides of the front of a car, used for illuminating the road during nighttime driving. Low beams fall within the category of headlights, but headlights are certainly not limited to just low beams. According to the definition, both low beams and high beams are types of headlights. 2. High beams: High beams focus their light parallel to the road, emitting a more concentrated and brighter light that can illuminate distant and high objects. 3. Low beams: Low beams emit light that diverges beyond their focal point (between 1x and 2x the focal length), covering a larger area at a closer range. Both are used for nighttime illumination, but high beams have a higher angle and longer range, while low beams have a lower angle and shorter range.

What is the Difference Between Front Radar and Rear Radar?

The difference between front radar and rear radar lies in their different purposes. 1. Front Radar: The front radar can detect obstacles that are below the bumper and difficult for the driver to see from inside the car, such as flower beds or playing children, and it will issue an alert. (The front radar probe is installed on the front bumper and scans at approximately a 45-degree angle to search for targets in all directions.) 2. Rear Radar: Also known as a parking sensor, it is a safety aid for car parking or reversing. The probe is installed on the rear bumper. When the gear lever is shifted into reverse, the rear radar automatically starts working. When the probe detects an object behind the vehicle, the buzzer emits a warning sound. As the vehicle continues to reverse, the frequency of the alarm sound gradually increases, eventually turning into a continuous tone.

What is the difference between the 4G version and the WiFi version of car navigation?

The differences between the WiFi version and the 4G version of car navigation are as follows: 1. Different supported ranges: If it is a WiFi version navigation, it does not support the installation of a SIM card. If it is a 4G version navigation, a SIM card can be installed. 2. Different usage methods: The WiFi version navigation must use a mobile phone to create a hotspot, and then the central control screen must turn on WiFi to connect to the mobile phone hotspot to access the internet. The 4G version navigation can directly install a SIM card to access the internet without the need to use a mobile phone to create a hotspot. The 4G version navigation can also create a hotspot, and after turning on the mobile phone WiFi, the mobile phone can connect to it.
