What brand is SRAM derailleur?

Is it harmful to the circuit if the car charger is always plugged into the cigarette lighter?

No harm. After the vehicle is started, the voltage required by the cigarette lighter can be sufficiently supported by the vehicle's generator. Regarding the car charger, please note the following precautions: Charge after starting: Make sure to plug in the device for charging only after the engine is started. The low voltage during car ignition may affect the charging effect or even damage the car charger. Pay attention to the usage environment: Do not use the car charger during thunderstorms. Also, avoid using it after car washing, as high humidity inside the car can cause component corrosion and oxidation. Do not use the car charger in humid environments. Do not store the car charger in damp conditions. The suitable operating temperature range is 0-45°C. Keep it away from children. Unplug the charger promptly after charging. Reduce high-power usage: Avoid powering more than three devices simultaneously to prevent damage due to excessive power.

What are the speed ranges for first, second, third, and fourth gears in a car?

First gear is the starting speed, typically ranging from 0 to 5 kilometers per hour. Second gear corresponds to speeds between 5 and 20 kilometers per hour. Third gear covers speeds from 20 to 40 kilometers per hour, while fourth gear is suitable for speeds between 40 and 60 kilometers per hour. Fifth gear is used for speeds ranging from 60 to 100 kilometers per hour. Optimal upshift timing: When the engine has ample power, it produces a muffled sound. After upshifting, if there is no power deficiency or drivetrain vibration, and the vehicle accelerates smoothly and naturally, it indicates the upshift timing is correct. Downshift timing: When the vehicle's speed and engine RPM continuously decrease, and you feel the car shaking or the engine compartment vibrating, it's time to downshift one gear. Downshifting too early can cause jerking, waste engine power, increase fuel consumption, and negatively impact the lifespan of the engine and transmission. Downshifting too late may result in insufficient power even after the gear change, leading to continued jerking during further downshifts. Misjudging the shift timing can cause irreversible consequences and affect the driving experience.

What Causes the ABS Light to Illuminate in a Car?

There are various states of the ABS light being on, with different causes and solutions for each state. The details are as follows: State 1: ABS warning light stays on (most common). Cause 1: The ABS wheel speed sensor's sensing part is covered by dirt, mud, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to adjust braking. Solution: Clean the dirt from the wheel speed sensor and adjust the gap between the sensor and the signal ring to restore normal function. Cause 2: Poor signal due to loose connections between system lines or poor contact of the ABS relay, leading to system failure. Solution: Check the connection points of the lines and reconnect any loose parts. State 2: ABS warning light intermittently illuminates but turns off when accelerating. Cause: When multiple vehicle electrical devices are in use, the battery voltage drops below 10.5V. The ABS warning light turns off as the engine speed increases and voltage rises. This may also occur if the ABS system's power supply voltage is too low due to poor terminal contact or grounding issues. Solution: Check the battery's specific gravity; inspect the charging system; examine the power supply (e.g., voltage relay or poor power contact). State 3: ABS warning light stays on after engine start and only turns off when the engine is turned off (IGFF). Cause: Poor grounding contact of the ABS hydraulic valve body; poor contact of the ABS hydraulic valve body's electrical connector; ABS computer malfunction. Solution: Loosen and then retighten the grounding screw of the hydraulic valve body, cleaning the contact surface if necessary; check if the connector gap has widened; replace the ABS or ABS/ASR computer. State 4: ABS warning light illuminates during high-speed driving. Cause: During high-speed driving, the ABS computer detects a significant discrepancy between the rear and front wheel speed signals; incorrect tire or wheel rim specifications. Solution: Refer to the vehicle's tire and wheel rim specifications, as indicated on the label near the fuel tank cap. State 5: ABS warning light intermittently illuminates. Cause: Improper adjustment of the brake light switch; poor internal contact of the brake light. Solution: With the engine running, press the brake pedal and push the brake switch linkage down fully with your fingers, then release the brake pedal to complete the self-setting position; replace the brake light switch if necessary. If the ABS warning light is on, it is advisable not to continue driving. An illuminated ABS light indicates a malfunction in the vehicle's anti-lock braking system. During emergency braking, if the wheels lock up, the vehicle may skid uncontrollably, making it difficult for the driver to slow down or adjust the vehicle's trajectory, posing significant safety risks.

Which dash cams continue working after the car is turned off?

Use a dash cam equipped with parking surveillance, also known as motion detection function. Below is extended information about the motion detection feature: Working conditions for parking surveillance: The parking surveillance function requires the dash cam to have a built-in battery or be connected to the ACC fuse for power supply. After the vehicle is turned off, it automatically enters parking surveillance mode, where sensors continuously monitor the vehicle's condition. If any abnormality or vibration is detected, it automatically records surveillance footage and saves it separately. Protecting the battery: Compared to being connected to constant power, dash cams with parking surveillance connected to the ACC fuse are more power-efficient and have less impact on the car battery. However, if the vehicle is left unused for several consecutive days, it may still lead to battery drain and starting difficulties.
