The consequences of not replacing the air filter for 2 years are as follows: 1. It will affect the engine's air intake, leading to a lack of power during acceleration; 2. The engine will experience increased wear and carbon buildup, shortening its lifespan; 3. The phenomenon of "cylinder scoring" may occur. Here is an introduction to the car air filter: 1. The general replacement cycle for an air filter is 10,000 to 20,000 kilometers, which is heavily influenced by driving conditions. If the environment is poor, it needs to be replaced earlier. If the air filter is replaced after 30,000 to 40,000 kilometers, it mainly depends on the condition of the air filter. It is best not to go too long without replacement and to replace it within the specified time. 2. When installing a new air filter, pay attention to the correct orientation. There is a protruding plastic tab on the lower right side of the air filter to prevent incorrect installation. To ensure proper installation, the plastic tab must be secured into the slot of the filter housing.

The air filter in my previous car hadn't been replaced for two years, and the car started running poorly. When accelerating, the engine seemed to gasp, and it took a long time to respond after stepping on the gas pedal. Fuel consumption also skyrocketed, costing me at least an extra 150 yuan a month on gas. Later, during maintenance, the mechanic said the filter was clogged with dust, preventing air from entering and causing incomplete combustion, which even damaged the cylinders. The repair cost nearly 2,000 yuan. This thing mainly filters out impurities from outside the car, and improper maintenance can affect the engine's lifespan. It's recommended to replace it every 10,000 kilometers or once a year. Checking it myself is simple—just pull it out to see if it's dirty or black, then replace it with a new one. Don't follow my example and wait until the problem worsens—that's truly a case of being penny-wise and pound-foolish.

What are the three standard photos for running a red light?

The determination is made by capturing three photos with an electronic camera: the first photo shows the vehicle crossing the stop line at the intersection, including the red light signal and license plate number; the second photo shows the vehicle completely passing the stop line, including the red light signal and license plate number; the third photo shows the vehicle continuing to move, primarily by comparing the vehicle's position changes from the second photo, including the red light signal and license plate number. Capturing these three photos confirms the vehicle ran a red light. The act of running a red light is clearly defined in the "Road Traffic Safety Law." Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage, and driving through an intersection during a red light constitutes a traffic violation. Six scenarios of running a red light: Stopping immediately after crossing the line at a red light (when the light turns red, the vehicle cannot stop in time, and the front of the vehicle crosses the stop line): If the vehicle has just crossed the stop line during a red light but stops immediately, this is not penalized as running a red light. However, if there is noticeable movement after crossing the line, it will be penalized. The three photos captured by the electronic eye for running a red light are: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are present will it be deemed as running a red light, resulting in a 6-point deduction under Article 2 of the "Road Traffic Violation Points System." Running a red light under police direction (the signal is red, but the traffic officer signals permission to proceed): When there is a conflict between the traffic signal and the officer's gesture, motor vehicle drivers must obey the officer's on-site command. If a driver runs a red light due to the officer's command, they can obtain a diversion certificate from the local traffic police department to avoid penalties. If the driver disputes the penalty, they can appeal through administrative reconsideration or administrative litigation. Stopping with the entire vehicle over the line at a red light (failing to brake in time, causing the entire vehicle to cross the stop line): If the vehicle stops completely after crossing the stop line without further movement, it is not considered running a red light but rather stopping beyond the line. Reversing after stopping beyond the line (attempting to avoid penalties by reversing after stopping beyond the line at a red light): Motor vehicles are prohibited from reversing at railway crossings, intersections, one-way roads, bridges, sharp curves, steep slopes, or tunnels. Violations may result in a warning or fine. Accidentally running a red light behind a large vehicle (due to obstructed visibility from the large vehicle ahead, following it through the intersection): Drivers must maintain sufficient visibility to see the traffic signals ahead and ensure a safe braking distance. Generally, if a motor vehicle is photographed behind a large vehicle, it is due to rushing through the intersection. This behavior will be penalized as running a red light. Passing through an intersection during a yellow light (crossing the intersection when the signal turns yellow):

What is the most accurate reference point for driving straight?

When driving straight, the left edge of the road should be used as the reference point. Below is relevant information about driving straight: 1. Introduction: Driving straight refers to novice drivers starting the vehicle, gradually accelerating to shift from the lowest gear to the highest gear, achieving high speed. 2. Techniques for driving straight: The driver should look ahead and pay attention to both sides, select a reference point, maintain a straight path, promptly correct the direction, and always be aware of traffic conditions ahead to detect and handle situations in time. The driver should look far ahead while keeping an eye on the near distance, holding the steering wheel straight, adjusting the viewing distance according to the speed. At higher speeds, look further ahead; at lower speeds, look relatively closer, while using peripheral vision to monitor the surroundings of the vehicle.

What to Do When the Paint on the Front of the Car is Scratched?

After the paint on the front of the car is scratched, handle it according to the following situations: 1. Slight paint damage: Basically, no action is needed. Minor scratches on a car are inevitable; even stones flying off the road can cause scratches. This is a minor scrape, leaving a mark that can often be wiped off with a wet towel after a couple of wipes. If the scratch isn't very noticeable, simply applying wax is sufficient; even a non-abrasive polish wax can work well. 2. Mild paint damage: After wiping with a wet towel, there will still be relatively obvious scratches that cannot be removed with water. It's best to apply wax, such as water wax or soft wax containing abrasives, which can be either solid or liquid. Alternatively, a touch-up paint pen can be used for minor repairs. 3. Moderate paint damage: Seek repair at a maintenance shop.

Is the Rear Vehicle Fully Liable for a Rear-End Collision When the Front Vehicle Brakes Suddenly on the Highway?

When the front vehicle brakes suddenly on the highway, resulting in a rear-end collision, the rear vehicle is generally liable. However, if evidence proves that the front vehicle braked abruptly, the front vehicle may also share responsibility. Related details: 1. Liability Determination: Even if the front vehicle brakes suddenly, the rear vehicle must always maintain a safe distance and speed. If a rear-end collision occurs, the rear vehicle is typically at fault. However, if evidence shows the front vehicle braked abruptly, the front vehicle may also be held accountable. 2. Prevention Measures: Generally, vehicles on the road should maintain sufficient distance between each other. The rear vehicle should not follow too closely, as adequate space and reaction time are necessary to prevent accidents.

Does the vehicle owner need to be present for re-stamping the VIN?

Re-stamping the VIN does not require the vehicle owner to be present in person, but the owner's ID card is required for the procedure. Relevant information: 1. Required materials: The vehicle registration certificate, purchase certificate, and the owner's ID card need to be brought to the vehicle management office to apply for the procedure, and then the re-stamping will be done at a designated location. 2. Additional information: The full name of the VIN is the Vehicle Identification Number, which is a unique set of alphanumeric characters assigned by the manufacturer to identify a vehicle. It consists of a 17-character code, also known as the 17-digit identification code, chassis number, or 17-digit number. The combination of characters in the VIN ensures that no two vehicles of the same model will have the same number within 30 years, making it a unique identifier for the vehicle, hence it can be referred to as the 'vehicle's ID card'.

What Causes the Car Air Conditioner to Alternate Between Hot and Cold?

Introduction to the reasons why a car air conditioner alternates between hot and cold: 1. Damaged compressor capacitor: For the air conditioner to function properly, both the internal and external units need to work together. If the car air conditioner exhibits alternating hot and cold air, check if the external unit's compressor start capacitor is damaged. If so, it needs to be replaced. 2. Dirty filter: If the air conditioner hasn't been cleaned for a long time, it can also cause the air conditioner to alternate between hot and cold. A dirty filter or evaporator can easily lead to poor ventilation and heat dissipation, causing the compressor to overheat and shut down. Therefore, regular cleaning is necessary to maintain cleanliness. 3. Insufficient refrigerant: The air conditioner requires an adequate amount of refrigerant, commonly known as Freon, to cool. If the temperature inside the car alternates between hot and cold, check if the refrigerant in the air conditioning system is insufficient. If so, use other methods to address the issue. 4. Moisture in the air conditioning system: When high-temperature, high-pressure liquid passes through the expansion valve, all the liquid undergoes a rapid change, turning into low-temperature, low-pressure liquid. This low-temperature, low-pressure liquid causes the temperature of the evaporator to drop rapidly, so the air blown by the air conditioner motor becomes cold after passing through the evaporator.
