When the engine number or vehicle identification number becomes unreadable due to wear and rust, or is already damaged, you need to apply for record filing at the local vehicle registration office. If not filed, you may be stopped and penalized by traffic police while driving on the road. Generally, it is a combination of 7 to 8 digits and English letters. In addition to the above method, the engine number can also be checked through the following 4 ways: The vehicle license shows the engine number, usually located in the second-to-last line; The motor vehicle registration certificate will state the engine number; The car purchase invoice will state the engine number; The vehicle purchase tax payment certificate will state the engine number. It should be noted that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer, and engine models can be the same. The engine number refers to the production number of the engine, where each engine can only use one engine number and each engine's number is unique.

The engine number on my old car rusted once, which was quite a hassle. I used a small brush and rust remover to scrub it gently, being careful not to apply too much force to avoid scratching the surface. For deeper rust spots, I sought help from a mechanic to grind and restore them. The vehicle identification number (VIN) at the bottom left corner of the windshield is also prone to rust. I usually park away from rain and dampness and apply some anti-rust oil for protection. This code is crucial for buying, selling, and handling paperwork—if it becomes unreadable, it can cause delays. I recommend checking it during annual maintenance to avoid last-minute fixes. Nowadays, there are professional cleaning tools available on the market, and spending a little money on them makes the job much easier. In short, take your time and prioritize safety when dealing with rust.

Can Automatic Transmission Cars Stall?

Automatic transmission cars can stall. Here are the relevant explanations: 1. Throttle valve contamination: Carbon deposits on the throttle valve directly affect its operation. If not cleaned for a long time, carbon buildup can cause errors in the throttle opening and allow air with impurities to enter the engine cylinders, leading to abnormal engine operation. 2. Fuel injector clogging: The fuel injector in the fuel system is prone to carbon deposits. Over time, carbon and gum formed from gasoline combustion can adhere to the injector, causing carbon buildup and even clogging. 3. Fuel pump failure: A faulty fuel pump can result in insufficient fuel supply, with symptoms similar to other fuel system issues (like injector failure), such as weak acceleration, fuel cut-off during sudden acceleration, difficulty starting, abnormal noises, engine shaking, and in severe cases, stalling while driving—including automatic transmission models. 4. Ignition coil failure: If the ignition coil fails, it can cause abnormal engine operation, shaking, weak acceleration, and misfiring. Failure of multiple ignition coils can lead to stalling. 5. Spark plug failure: Similar to ignition coil failure, faulty spark plugs can cause misfiring, weak acceleration, and shaking, often referred to as "backfiring." Multiple spark plug failures can result in stalling while driving, including in automatic transmission cars.

Symptoms of a Faulty Camshaft Sensor?

Camshaft sensor failure symptoms: Difficulty accelerating, ignition problems, persistent idle fault light, sudden engine stall when the car is warm. Here are the relevant details: 1. Function of the Camshaft: It is a component in a piston engine. Its role is to control the opening and closing of the valves. The design requires high strength and support for the camshaft, which is typically made of high-quality alloy steel or alloy steel. Since the valve movement pattern affects an engine's power and operational characteristics, camshaft design plays a crucial role in the engine design process. 2. Camshaft Position Sensor: Also known as the cylinder identification sensor, to distinguish it from the crankshaft position sensor (CPS), the camshaft position sensor is generally denoted as CIS. The camshaft position signal is also used to identify the first ignition timing during engine startup. Because the camshaft position sensor can identify which cylinder piston is about to reach top dead center, it is called the cylinder identification sensor.

Application Requirements: (1) Applicants must be at least 18 years old, with the maximum age range being 18-70 years, and a height of 150cm or above (155cm or above for large trucks). (2) No red-green color blindness. (3) Naked or corrected visual acuity must reach 4.9 or above on the logarithmic visual acuity chart. (4) Hearing must be sufficient to discern the sound source with each ear at 50cm from the tuning fork when wearing hearing aids. (5) Both thumbs must be intact, and each hand must have at least three other fingers intact. 2. Physical Examination Fee: The cost is generally not high, and you can undergo the examination yourself. Some driving schools may also cover the examination fee on your behalf. 3. Photo Fee: A white-background, one-inch bareheaded photo is required at the time of application. You can take the photo at a designated location or find your own place to take it. 4. Driving Test Fee: The cost varies depending on the driving school. Some schools collect the fee at the time of application, while others require you to pay it yourself.

Does the first claim in the first year of a new car affect the second year's insurance?

Whether the first insurance claim in the first year of a new car affects the second year's insurance depends on the number of claims made. If the new car only had one claim in the first year of insurance, it will not affect the second year, and the premium will neither increase nor decrease. However, if the policyholder makes two or more claims in the first year, it will affect the premium in the second year, which will increase by a certain proportion based on the claim situation. More relevant information is as follows: Reducing insurance premium rates: If the insured vehicle has no road traffic safety violations or road traffic accidents, the insurance company should reduce its premium rate in the next year. In subsequent years, if the insured vehicle still has no road traffic safety violations or road traffic accidents, the insurance company should continue to reduce its premium rate until it reaches the minimum standard. Increasing insurance premium rates: If the insured vehicle has road traffic safety violations or road traffic accidents, the insurance company should increase its premium rate in the next year. If there are multiple road traffic safety violations, road traffic accidents, or major road traffic accidents, the insurance company should further increase the premium rate.

What does SOC mean in new energy vehicles?

SOC, short for State-of-Charge, refers to the battery's state of charge, also known as remaining capacity. It represents the ratio of the remaining dischargeable capacity of a battery after being used for a period or left unused for a long time to its fully charged capacity. Other indicator lights on the car dashboard are as follows: 1. Hazard Warning Light: The hazard warning light is used to alert other vehicles and pedestrians when the car has a major malfunction or is in an emergency situation. The hazard warning signal is indicated by the simultaneous flashing of the front, rear, left, and right turn signals. 2. Battery Indicator Light: This light displays the working status of the battery. It lights up when the ignition is turned on and goes off after the engine starts. If it does not light up or remains lit continuously, the generator and circuit should be checked immediately. 3. Fuel Indicator Light: This light indicates insufficient fuel. When it lights up, it means the fuel is about to run out. Generally, the vehicle can still travel about 50 kilometers from the time the light comes on until the fuel is completely exhausted.
