The new regulations for yellow-label vehicles do not specify an age limit. Here are the details about yellow-label vehicles: 1. Definition of yellow-label vehicles: Yellow-label vehicles are a general term for high-pollution emission vehicles, referring to gasoline vehicles that do not even meet the National I emission standards or diesel vehicles that fail to meet the National III emission standards. They are called yellow-label vehicles because they are marked with a yellow environmental label. 2. Characteristics of yellow-label vehicles: Yellow-label vehicles have high emission volumes, high concentrations, and poor emission stability. Due to outdated exhaust emission control technology, their emissions do not meet the Euro I standards, and their emission levels are equivalent to 5 to 10 times that of new vehicles. The identification of yellow-label vehicles is based on exhaust emission standards. China implemented the 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (I)' in 2001, equivalent to the Euro I standard. In 2007, the 'Limits and Measurement Methods for Emissions from Light-Duty Vehicles (III)' was implemented, equivalent to the Euro III standard. Therefore, the National I emission standard specifies that carbon monoxide must not exceed 3.16 grams per kilometer, hydrocarbons must not exceed 1.13 grams per kilometer, and for diesel vehicles, particulate matter must not exceed 0.18 grams per kilometer, with a durability requirement of 50,000 kilometers. The National III emission standard specifies that hydrocarbons must not exceed 0.66%, carbon monoxide must not exceed 2.1%, particulate matter must not exceed 0.1%, and nitrogen oxides must not exceed 5%.

I've been driving for almost 20 years and know quite a bit about yellow-label vehicles. The new regulations generally consider the vehicle's registration date, and now most cities classify vehicles over 15 years old as yellow-label, meaning they fail to meet emission standards and cause high pollution. For example, my neighbor's old Santana, which was 18 years old, was restricted from driving last year. Under the new policy, some places like Beijing and Shanghai are tightening regulations even further. If your car was registered before 2000, you should check its emission certificate immediately, or you might face trouble entering urban areas. I think this policy helps reduce smog—older cars are prone to issues, so regular maintenance is essential. Otherwise, switching to a new energy vehicle might be a safer bet.

What are the consequences of being late for traffic duty during the driver's license test?

Consequences of being late for traffic duty during the driver's license test require honest apologies. Below are specific details about the driving test: 1. Subjects: The test is conducted sequentially with Subject 1, Subject 2, Subject 3, and Subject 4. 2. Retakes: For Subjects 2 and 3 of the driving test, candidates can only take each test five times. Failing beyond that requires re-paying the tuition fee. According to the Ministry of Public Security Orders No. 123 and 124, if the fifth scheduled test for the road driving skills (Subjects 2 and 3) is still failed, all previously passed subjects will be invalidated. To obtain a driver's license, one must re-register and pay the tuition again. 3. Traffic duty for the driving test: Traffic duty during the driver's license test refers to a requirement by some local driving schools where candidates must report to the local traffic police department before taking Subject 3 and complete four hours of street volunteer service.

Does Car Air Conditioning Consume Fuel or Electricity?

Car air conditioning consumes fuel. This is because the car's air conditioning compressor is driven by the engine's operation. Only when the engine reaches a certain operating speed can the air conditioning compressor function normally to provide cooling. Since the car's engine operates by burning gasoline, the air conditioning system essentially runs on fuel. The cooling process utilizes the circulation of refrigerant, which changes from a gaseous state to a liquid state in the engine compartment, releasing heat in the process. Inside the car, the liquid refrigerant evaporates back into a gaseous state, absorbing a significant amount of heat, thereby lowering the temperature inside the vehicle. The cooled air is then blown out through the blower behind the evaporator, allowing us to feel the cool air. Generally, the power used by the car air conditioning system accounts for about 20% of the engine's power. Therefore, using the air conditioning consumes 20% of the engine's power, leading to an increase in fuel consumption. The extent of this increase is also significantly influenced by the car's displacement and speed. Here are some methods to save fuel when using car air conditioning: Use air conditioning only at high speeds for better fuel efficiency: When driving in the city at lower speeds, many car owners prefer to open the windows instead of using the air conditioning, which is an effective way to save fuel. Avoid setting the air conditioning temperature too low: The lower the air conditioning temperature, the more fuel it consumes. Some car owners set the air conditioning to the lowest temperature to make the cabin cooler, but this not only increases fuel consumption but also creates a significant temperature difference between the inside and outside of the car. This can cause discomfort when exiting the vehicle and may lead to colds.

How to Clear the Engine Malfunction Light?

When the engine malfunction light is on, you can follow these steps to address the issue: First, check if the engine is running normally. Look for issues such as shaking or black smoke. If these symptoms are present, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'on' position without depressing the clutch. The vehicle will perform a self-diagnosis when powered on. After 5-10 seconds, observe whether the malfunction light on the dashboard turns off. If the light remains on, visit a service center as soon as possible to diagnose the issue. The service center can use a portable diagnostic tool to read the fault codes, identify the problem, and perform targeted repairs. There are seven main reasons why the engine malfunction light may illuminate: Sensor Failure: This includes sensors such as the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake temperature sensor, and oxygen sensor. Damage, poor contact, or signal interruption in these sensors can prevent the ECU from accurately obtaining engine data, triggering the malfunction light. Fuel or Oil Quality Issues: Using fuel or oil that does not meet the manufacturer's specifications may cause engine wear and trigger the malfunction light. Poor Combustion of Air-Fuel Mixture: Incomplete combustion can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the malfunction light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion. Turbocharger Problems: Issues with the intake boost piping or turbocharger can also trigger the malfunction light. The most common problem is a damaged turbocharger, which may also cause symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: Clogged engine intake pipes can lead to serious issues, including the illumination of the malfunction light. A dirty or uncleaned air filter can cause intake problems. Exhaust Problems: Exhaust system failures can also trigger the malfunction light. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is particularly prone to issues, especially if leaded gasoline, lead/silicon-based lubricant additives are used, or if the converter is physically damaged or the engine's fuel supply system malfunctions. Anti-Theft System Malfunction: If the car's electronic anti-theft system fails or the anti-theft controller does not match the engine ECU, the anti-theft system may prevent the engine from operating normally and trigger the malfunction light.

How Many Kilometers Can 50 Liters of Gasoline Drive?

How many kilometers 50 liters of gasoline can drive depends on the vehicle's fuel consumption. Assuming the vehicle's fuel consumption is 10 liters per 100 kilometers, then 50 liters of fuel can drive 500 kilometers. The calculation method is to divide 50 liters by 10 liters and then multiply by 100 kilometers. If the vehicle's fuel consumption is between 5 to 10 liters per 100 kilometers, then the driving range with 50 liters of fuel will be between 500 to 1000 kilometers. The level of a car's fuel consumption is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. The specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle in advance when approaching a red light, can increase fuel consumption. The car itself: Cars with larger displacement generally consume more fuel than those with smaller displacement because larger displacement usually means greater power, requiring more gasoline to burn and perform work. Cars with greater weight will have higher fuel consumption because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperature: When the engine block temperature is low, the gasoline injected during a cold start does not atomize easily, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.
