What is the voltage of a general car battery?

Generally, the voltage of a car battery is 12V. If measured with a multimeter, a battery voltage between 11.8V and 12.8V is considered normal. The car battery, also known as the storage battery, is an indispensable part of a vehicle and can be categorized into traditional lead-acid batteries and maintenance-free batteries. Since the battery uses a lead-calcium alloy for the grid frame, the amount of water decomposed during charging is minimal, and the water evaporation rate is also low. Additionally, the sealed structure of the casing releases very little sulfuric acid gas. Compared to traditional batteries, it has advantages such as not requiring any liquid addition, easy connection to terminal posts, and a long power storage duration.

Will engine oil burn when exposed to an open flame?

Engine oil generally does not burn when exposed to an open flame, provided there are no flammable attachments present. Since engine oil itself is flammable, it will ignite if it carries any attachments with an open flame. For safety reasons, it is advisable to avoid exposing engine oil to open flames. Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption and cushioning. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, imparting certain new characteristics, making them an essential part of lubricating oil.

Why Does the Car Fan Keep Running After the Engine Is Turned Off?

The reasons why the car fan keeps running after the engine is turned off are: 1. The higher the coolant temperature after parking; 2. Short circuit in the fan motor or control circuit; 3. Damage to the water temperature sensor or stuck contacts of the fan relay. The function of the fan is: to increase the air velocity through the radiator core, enhance the cooling effect, and accelerate the cooling of water. The solutions for a car fan that keeps running after the engine is turned off include: 1. Wait for ten minutes to observe whether the fan continues to run; 2. Conduct a comprehensive inspection of the cooling system; 3. Unplug the fan wiring harness for separate power-off treatment; 4. Go to a repair shop to replace the sensor or relay with a new one.

Will Water Enter the Car When Parking Uphill on a Slope During Rain?

Parking uphill on a slope during rain will not cause water to enter the car. Here are the relevant details: 1. Hazards of parking on a slope: Damage to the handbrake braking system; Impact on the suspension; Risk of the car rolling; Increased likelihood of scraping accidents. 2. Harm caused by rainwater to the vehicle: Paint aging and corrosion; Corrosion of the chassis; Moisture and mold inside the car; Breeding of bacteria; Impact on electrical circuits, damaging the engine; Damage to headlights, etc. The chassis can be eroded by acid rain. Thunderstorm weather can also lead to water accumulation on the road. After the vehicle passes through waterlogged areas, acidic rainwater can adhere to the chassis. Retention of acid rain on the chassis can lead to rusting of the chassis.

Should the Dashcam's G-Sensor Be Enabled?

Dashcam's G-sensor can be enabled, but it is recommended to set it to a low sensitivity option and regularly format the memory card to prevent the card from storing too many non-overwritable videos, which would reduce the available space for loop recording. The G-sensor, also known as collision detection storage, works by the dashcam's CPU detecting when the values from the gravity sensor exceed the preset threshold, at which point it assumes a collision has occurred and protects the current video segment from deletion, thereby achieving the function of automatically storing footage during collisions. A dashcam is an instrument that records images, sounds, and other relevant information during vehicle operation. It can utilize high-definition lenses to comprehensively document driving footage, audio, and vehicle status data.

Should You Use High Beams or Low Beams When Driving in the Rain?

When driving in the rain, use low beams along with position lights, and turn on fog lights when the rain is heavy. High beams can create a dazzling glare in rainy or foggy conditions, affecting surrounding vehicles, so they should not be used. Hazard lights should also not be used indiscriminately while driving; they should only be activated when parked or during emergency braking. Tips for driving in the rain: 1. Before heading out, check if the windshield wipers are functioning properly and clearing water effectively; 2. If fog forms on the windshield, quickly turn on the defroster or air conditioning to maintain clear visibility; 3. Reduce speed and maintain a safe distance from the vehicle ahead when driving on wet or slippery roads; 4. Slow down before turning, appropriately increase the turning radius, and steer gently to prevent loss of vehicle control.
