Why is there abnormal noise during cold start?

Reasons for abnormal noise after cold start: 1. Belt aging: The generator belt ages, and its rubber material is affected by thermal expansion and contraction. When the car is cold, the belt contracts, and daily rotation stretches the belt, which can easily cause the belt to slip during cold start, producing noise. 2. Valve tappet: Due to the valve tappet, during cold start, engine oil is pressurized from the oil pump into the engine oil passage before reaching the valve tappet, which can cause increased noise during cold start. 3. Loss of lubrication: The internal gears of the starter lose lubrication, causing sticking and affecting the timely return of the gears. 4. Carbon brush failure: The carbon brush inside the starter motor malfunctions.

Can the ETC card be turned off when not in use?

ETC's card can be removed when not in use, but be careful not to remove the card during use, otherwise it will cause the ETC to fail to work properly. Benefits of installing ETC: Save time: Avoid the hassle of queuing up; Green and environmentally friendly: Green and low-carbon, vehicles can pass through toll stations without stopping, reducing noise and exhaust emissions and pollution; Save wear and tear: Save costs, reduce the frequency of vehicle starts and brakes, reduce wear and fuel consumption, and users can also enjoy a 5% discount on tolls; Improve efficiency: The efficiency of ETC lanes can theoretically be increased by 2-3 times, making traditional ETC newer, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. ETC working principle: Through the dedicated short-range communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna on the ETC lane of the toll station, the computer network technology is used to conduct background settlement processing with the bank, so that vehicles can pass through the highway or bridge toll station without stopping, and can pay the highway or bridge toll.

Can the dash cam record sound inside the car?

The dash cam can record sound inside the car, allowing you to hear conversations in the vehicle. Here is some relevant information about dash cams: 1. Purchase considerations: When purchasing a dash cam, pay attention to the following: choose a product with a wide shooting angle and high resolution, which is more conducive to comprehensively recording the surrounding conditions of the vehicle; select a dash cam with good concealment to avoid the risk of window smashing and theft; opt for genuine, well-known brands, which are more trustworthy and offer better guarantees. 2. Description: A dash cam is an instrument that records images, sounds, and other relevant information during vehicle travel. There is a recording button on the dash cam, and turning it on enables normal recording. Currently, most dash cams on the market come with a recording function, which is a standard feature for the majority of them. Of course, since the interior of a car is relatively private, some people may not prefer recording. To ensure privacy, the recording function can be turned off in the settings interface.

What are the benefits of SUVs?

The benefits of SUVs include: 1. Better visibility: As is well known, SUVs have a relatively higher chassis, which ensures clearer visibility for the driver. 2. Superior off-road capability: Regardless, it has the advantage of a high chassis, which other vehicle types cannot match. If combined with an inverted V-shaped suspension and full-time four-wheel drive, the all-terrain functionality of this vehicle type far surpasses that of sedans. 3. Spacious interior: SUV models do not have the middle bulge in the rear seating area, making the space appear neat and tidy. In fact, the size of a car is not determined by its exterior but mainly by its wheelbase. Vehicles in the same class generally have similar wheelbases. The reason SUVs appear larger is because of their elevated chassis, which reduces the limitations on rear seating space imposed by the rear axle.

How to Open a Car Battery Cover?

The car battery cover cannot be opened directly and requires the use of tools to break it open. Here is some relevant information about car batteries: 1. Overview: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, what people refer to as a battery is a lead-acid battery, which is mainly composed of lead and its oxides, with a sulfuric acid solution as the electrolyte. 2. Classification and Characteristics: (1) Conventional Battery: The plates of a conventional battery are made of lead and lead oxides, with a sulfuric acid solution as the electrolyte. Its main advantages are stable voltage and low cost; the disadvantages include low specific energy (the amount of electrical energy stored per kilogram of battery), short lifespan, and frequent maintenance. (2) Dry-Charged Battery: Its full name is a dry-charged lead-acid battery. The main characteristic of this battery is that the negative plate has a high capacity for storing electricity. In a completely dry state, it can retain the stored charge for up to two years. When in use, you only need to add the electrolyte and wait for 20–30 minutes before it can be used.

Why does the engine make a buzzing sound after shutting down?

It is normal for a car to make a buzzing sound after shutting down. The sound may come from the turbocharger, or there may be abnormal noise when the automatic parking system intervenes during braking. Here are the detailed explanations: 1. After continuous high-speed rotation, the engine temperature will rise accordingly, causing the engine to become very hot and emit a buzzing sound. You can try not to shut off the engine immediately after stopping; wait for a while before turning it off. 2. The sound may come from the three-way catalytic converter. The operating temperature of the three-way catalytic converter is close to 1000 degrees Celsius, and the internal metal parts will expand and contract due to heat after shutting down. If none of the above situations apply, it may be a vehicle malfunction, and you should have it checked promptly.
