Can a Dash Cam Record Inside the Car?

Dual-lens dash cams can record inside the car, while single-lens dash cams cannot. Dash cams record the driving process, and the recorded videos can provide evidence to traffic police in case of an accident, helping to quickly and accurately handle the situation. They can also prevent fraud incidents, avoiding unnecessary trouble and losses, thereby protecting the driver's interests. Relevant information about dash cams is as follows: 1. A dash cam is an instrument that records images, sounds, and related information during vehicle travel. 2. All dash cams support loop recording, with loop settings typically at 1, 2, 3, 5, or 15 minutes. Generally, 3 or 5 minutes is most suitable; durations that are too long or too short are not advisable.

Why Does the Car Horn Sound Different in Winter?

The reasons for the change in car horn sound during winter are: 1. The rubber of the horn becomes hardened due to weather conditions; 2. Damage to the horn relay, horn contacts, or the horn's power supply circuit. Precautions for using car horns include: 1. Avoid getting the horn wet when washing the car, and dry it immediately if it gets wet; 2. Avoid pressing the horn for extended periods to prevent premature burn-out of the contacts. The working principle of a car horn is: When the horn button on the steering wheel or elsewhere is pressed, current from the battery flows through the circuit to the electromagnetic coil of the horn relay. The coil attracts the moving contact switch of the relay to close, allowing current to flow to the horn. This current activates the electromagnet inside the horn, causing the diaphragm to vibrate and produce sound.

How to Solve Intermittent Idle Vibration When the Engine is Warm?

Intermittent idle vibration when the engine is warm can be resolved by: 1. Cleaning carbon deposits from the vehicle's engine; 2. Replacing the engine oil and oil filter. Methods for engine maintenance include: 1. Using qualified engine oil; 2. Using qualified coolant and antifreeze; 3. Regularly cleaning radiator scale; 4. Regularly removing engine carbon deposits; 5. Periodically replacing the three automotive filters; 6. Maintaining reasonable engine RPM. The function of the engine is: to serve as the power-generating device for the automobile, determining its power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, automotive engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid power systems.

How Long Can Faux Leather Seats Last?

If properly maintained, faux leather seats can last for five to six years without issues. For high-end faux leather seats, they can even last for eight to ten years. Here are some relevant tips: 1. During summer, try to avoid parking outdoors as prolonged exposure to direct sunlight can cause the faux leather to crack due to high temperatures. 2. The quality of faux leather seats varies depending on the material. High-end automotive faux leather offers advantages such as wear resistance, cold resistance, breathability, aging resistance, soft texture, environmental friendliness, and an attractive appearance. 3. When purchasing faux leather seats, it's advisable to choose well-known brands even if they cost more, as they generally offer better quality assurance compared to lesser-known brands.

What to Do When the Car Air Conditioner Fan Doesn't Rotate?

The car air conditioner fan may not rotate due to the following 4 reasons: 1. Relay failure: If the relay fails, the car's radiator fan won't work either. If the water temperature is normal but the radiator fan still doesn't operate, the issue might be with the fan's relay. 2. Poor contact in the main control switch or damaged fan motor coil: Use a multimeter to measure the contact resistance of the main control switch. If the resistance is too high or zero, repair or replace it. 3. Loose set screw between the fan motor and blade: Tighten the set screw. 4. Open or short circuit in the fan capacitor: Inspect the capacitor and replace it with one of the same specifications.

Why Do Supercars Use Dry Sump Lubrication?

Dry sump lubrication ensures engine lubrication without causing damage, which is why supercars utilize this system. In contrast, ordinary family cars typically employ wet sump lubrication, where oil is stored in the sump and provides splash lubrication and pressure lubrication during engine operation. Key information about dry sump lubrication is as follows: 1. Dry sump systems are used in many racing engines. They do not store oil in the sump—more accurately, they lack a traditional oil pan. 2. Dry sump systems avoid various adverse phenomena associated with wet sump systems during aggressive driving. 3. Since dry sump engines eliminate the oil storage function of the sump, the height of the original oil pan is significantly reduced, lowering the engine's overall height. This reduction in center of gravity enhances handling performance.
