Can a new car with a temporary license plate but no vehicle license be driven on the road?

It is not allowed to drive on the road with a temporary license plate but no vehicle license. Vehicles on the road must have a vehicle license and corresponding license plates. Below is an introduction to temporary license plates: Introduction to temporary license plates: A temporary license plate is a paper motor vehicle license plate that allows a motor vehicle to temporarily drive on the road, also known as a temporary driving license plate. It refers to the temporary vehicle driving certificate issued by the public security vehicle management department for newly purchased vehicles before they are officially registered. The validity period of a temporary license plate generally does not exceed thirty days. How to apply for a temporary license plate: New cars without license plates are not allowed on the road; otherwise, they will be fined 200 yuan and have 12 points deducted. After purchasing a new car, the owner must promptly complete the motor vehicle registration procedures or apply for a temporary driving license plate. Before driving on the road, the owner can apply for a temporary driving license plate from the traffic management department of the public security authority (vehicle management office) by providing proof of identity, vehicle purchase invoice, new vehicle certificate, compulsory insurance certificate, import certificate, and copies of related documents.

What to Do If the Steel Rim Rusts?

Here are the methods to deal with rust on steel rims: 1. If the rust is not severe, you can first use very fine water sandpaper dipped in water to gently sand off the rust spots, completely clean it, and then apply a layer of primer to ensure the rust does not spread or worsen. 2. If it is a new scratch, you can clean it and directly apply primer. Generally, vehicles come with a small can of original paint. Although this treatment may not look great, it is not a big issue for very small areas. Additional Information: 1. In fact, wheel rim rust does not necessarily mean the rim is truly rusting. It is often because the car has been in a humid environment for a long time, combined with prolonged use, which inevitably leads to some bumps and scratches on the rim surface. Then, when washing the car outside, exposure to poor-quality cleaning agents containing acids or alkalis can cause the rim to corrode and rust. 2. Although small rust spots on steel rims can be treated by sanding and applying primer yourself, this method does not fundamentally solve the problem. Moreover, the primer you apply yourself will not last long and will eventually peel off, which can be frustrating. The most correct approach is to repair the rim as soon as there are scratches on the surface, before rust appears, to prevent the rim from rusting when exposed to cleaning agents. After all, if the rim rusts and corrodes too severely, damaging the aluminum alloy material, the rim will gradually become unusable. Therefore, once scratches, chips, or other damage appear on the wheel rim, it is essential to promptly seek professional repair services from a specialized wheel rim repair shop.

Are 4S Stores Nationwide Chain Warranties?

4S stores are nationwide chain warranties. Here is a brief introduction about 4S stores: 4S stores have a unified appearance, standardized management, and exclusively operate under a single brand, which greatly enhances the brand image of automobiles and promotes car models. Introduction to 4S Stores: The sales model of 4S stores gradually entered the Chinese automobile market in 1998, as 4S stores established close sales relationships with major automobile manufacturers. With advantages such as a pleasant shopping environment and strong brand awareness, they have gradually become a key model for automobile sales in China, contributing to the circulation of the Chinese automobile market. Automobile Warranty Period: The automobile warranty period refers to the time frame during which automobile manufacturers promise to provide free repairs and maintenance for faults caused by quality issues when selling products to consumers. Currently, most automobile manufacturers implement a new vehicle warranty period, 'two years or 60,000 kilometers, whichever comes first.' This means there are two conditions for the warranty period: one is a time limit of two years, and the other is a mileage limit of 60,000 kilometers. Once either of these conditions is met, the vehicle's warranty period is considered expired, and normal maintenance and repairs are no longer free. During the warranty period, not all repair costs are waived; it depends on the free items specified by the manufacturer within the warranty period. Usually, relevant descriptions can be found in the owner's manual and the after-sales departments of various automobile 4S stores. Therefore, owners are advised to carefully read the manual to avoid unnecessary expenses during the warranty period.

What are the differences between single overhead camshaft and double overhead camshaft?

Single overhead camshaft is arranged with one camshaft in a cylinder head, while double overhead camshaft is arranged with two camshafts in a cylinder head. The detailed introduction is as follows: Single overhead camshaft: Before the emergence of double overhead camshaft, single overhead camshaft was simply called OHC, as there was no distinction between single and double. The camshaft of a single overhead camshaft is located at the top of the cylinder, above the valves. The opening and closing of the valves are controlled by the shims between the crankshaft journals and the valve stems, or by rocker arms. The valve configuration of a single overhead camshaft engine usually has 2 to 3 valves per cylinder. There are also single overhead camshaft engines with 4 valves, but the rocker arms and camshaft journals become very complex. Double overhead camshaft: The camshaft is located on the cylinder head. In this structure, the camshaft directly drives the rocker arms, eliminating the need for tappets and pushrods, which greatly reduces the reciprocating mass. Therefore, it is suitable for high-speed engines. However, the timing transmission mechanism is complex, and it causes certain difficulties in disassembling and assembling the cylinder head. The double overhead camshaft means that the intake and exhaust valves are controlled by separate shafts.

How Long is the Interval Between Subject 1 and Subject 2 Exams?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the time interval between Subject 1 and Subject 2 varies depending on the type of license. For a C-class license, you can schedule the Subject 2 exam 10 days after passing Subject 1, while for A and B-class licenses, you must wait 20 days. This provides ample time to prepare for Subject 2. Each Subject 2 exam appointment allows for two attempts. If you fail the first attempt, you can retake it once for free. If you do not take the retest or fail the retest, the exam session ends. Within the validity period of the learner's permit, you can schedule the Subject 2 exam no more than five times. If you fail the fifth attempt, all previously passed subjects will be invalidated. To continue pursuing the driving license, you must restart the process from Subject 1. Taking the C1 license as an example, the Subject 2 exam includes: demonstrating the ability to complete driving tasks within a designated area, mastering vehicle control skills, and accurately judging the vehicle's spatial position. Subject 2, also known as the "small road test," consists of five mandatory tasks: reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and navigating an S-curve. Some regions include a sixth task: collecting a toll card on a highway. Subject 2 Exam Tips: After entering the car, adjust the seat and mirrors to the correct position and fasten your seatbelt. For parallel parking, find the right angle, turn the steering wheel quickly, and react promptly to match the car's speed. When stopping on a slope, remember to engage the handbrake. Before starting, turn on the left indicator, release the handbrake, and balance the clutch and throttle to avoid stalling or rolling back. For right-angle turns, react quickly once you find the reference point and coordinate with the car's speed to prevent deviation. For the S-curve, slow down and drive carefully. Those with good driving instincts may pass smoothly in one go. When reversing into a parking space, control the speed, identify reference points, and make minor adjustments if needed by checking the mirrors. The driving test consists of three subjects: Subject 1 (traffic laws and regulations), Subject 2 (field driving skills), and Subject 3 (road driving skills and safe driving knowledge). The safe driving knowledge test, often called "Subject 4," is taken after Subject 3. However, the official term (under the Ministry of Public Security's Order No. 123) does not include "Subject 4."

What is the function of turning on AC with car heater?

AC switch is the cooling switch of the car air conditioning. After pressing the AC switch, the compressor clutch of the car air conditioning will engage, and the engine can drive the compressor to operate. The following are the functions of AC: When the compressor is running, it can continuously compress the refrigerant and deliver it to the evaporator. The refrigerant can continuously expand and absorb heat in the evaporator, thereby cooling the evaporator. The cooled evaporator can cool the air blown by the blower, so that the car air conditioning vents can blow cold air. When using the car heater, there is no need to press the AC button, for the following reasons: The AC button controls the compressor switch, while the heater mainly uses the internal heat circulation of the car to maintain the temperature inside the car. During this process, the compressor does not work, and only the air volume needs to be adjusted. Turning on the AC button may cause unnecessary fuel consumption. There are four precautions for using the heater in winter. Do not use the heater immediately after a cold start: When the car is started cold, the temperature in the radiator is relatively low. If the heater is turned on, it will not only fail to increase the temperature inside the car but also increase the burden on the engine, slow down the engine temperature rise, affect normal use, and increase fuel consumption. It is recommended to wait 8-15 minutes after starting the car before turning on the heater. Control the heater system through the water temperature gauge: Do not turn on the heater when the water temperature gauge is at a low position. When the water temperature gauge reaches the middle position, you can use the heater. When using the heater, it is recommended to first use the external circulation to expel the cold air inside the car, which can quickly increase the temperature inside the car. Turn off the heater when parking for a long time: Especially when waiting for someone, if the time is too long, the heater should be turned off. Keeping the heater on for a long time can easily lead to carbon monoxide poisoning. If the heater needs to be used for a long time, you can leave a small gap in the window. Turn off the heater before turning off the engine: If the heater is not turned off, the next time you start the car, the heater will be turned on before the engine starts, which will affect the car air conditioning over time.
