What emission standard is currently implemented in Beijing?

Beijing is currently implementing the China 6b standard. Below is a detailed introduction to the national emission standards: 1. Purpose: The strict emission standards introduced by the government aim to regulate automakers, and stringent standards can phase out some older vehicles that fail to meet emission requirements. 2. Development of national emission standards: The China 6 standard implemented in 2019 was the China 6a standard, which served as a transitional standard from China 5 to China 6. The true China 6 standard is the China 6b standard. 3. Comparison between China 6a and 6b: The emission requirements for China 6b are nearly twice as strict as those for China 6a, and it also adopts a more rigorous Real Driving Emissions (RDE) test.

What to Do When the Dashboard Flashes Red After Locking the Vezel?

Close the car door tightly again or remove any obstructions. Below is relevant information about the dashboard flashing red: 1. Cause: The red light is an indicator for the vehicle's anti-theft system. It will light up when the car door is not closed tightly or when there is an obstruction blocking the door. 2. Principle: A typical mechanical odometer is connected to a flexible shaft, inside which there is a steel cable. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn drives a magnet inside the odometer cover to rotate. The cover is connected to the pointer and, through a hairspring, positions the pointer at zero. The speed of the magnet's rotation causes changes in the size of the magnetic field lines. When the balance is disrupted, the pointer is thus driven.

What does it mean when the center brake light is on?

The main reason for the center brake light to illuminate is an alert due to the high-mounted brake light not functioning. Below is an introduction to brake lights: 1. Introduction: The brake light is a crucial light on a vehicle. When the brake pedal is pressed, the brake light turns on, alerting drivers behind to maintain a safe distance. 2. Installation location and operation method: The brake light is typically installed at the rear of the vehicle, with a red color to make it easily noticeable for following vehicles, helping to prevent rear-end collisions. Power flows through a fuse to the brake switch. When the brake pedal is pressed, the switch connects, sending electricity to the two brake lights and the high-mounted brake light, completing the circuit through the negative wire connected to the vehicle body.

How to Enter and Exit Highway Toll Stations?

Open system and closed system toll collection. Below is more information about highway tolls: 1. Relevant information: According to the 2021 'National Expressway Toll Standards', there are two types of highway toll collection - open system and closed system. The open system involves collecting an IC card at the entrance toll station when entering the highway, then presenting it to the toll collector at the exit station who will charge the displayed fee by swiping the card. This method is generally used for longer highway routes and is the predominant toll collection method for most intercity highways nationwide. 2. Free periods: No toll will be charged if exiting the highway during designated free periods, which cover four national statutory holidays: Spring Festival, Qingming Festival, Labor Day, and National Day, including the consecutive holiday periods as determined by documents from the General Office of the State Council in that year.

What Are the Reasons for High Car Fuel Consumption?

There are 4 main reasons for high car fuel consumption: 1. Insufficient tire pressure or severe tire wear: Tires are relatively easy to check, so they should be inspected first. If the tire pressure is insufficient, fuel consumption will increase; if the tire pressure is normal, then check the degree of tire wear. When tires are severely worn, they often show signs of slipping, which also increases fuel consumption. 2. Excessive carbon buildup in the car engine: This can lead to higher fuel consumption, and this situation is likely caused by using substandard fuel. 3. Damage to the oxygen sensor in the internal control unit: The oxygen sensor mainly monitors the fuel-air ratio in the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, inevitably leading to abnormally high fuel consumption. 4. Malfunction of a certain engine control unit: If one of the control units fails, it is highly likely to cause increased fuel consumption, accompanied by poor power performance and thick black exhaust emissions.

What Causes the Low-Pressure Pipe of a Car Air Conditioner to Freeze?

Here are the reasons why the low-pressure pipe of a car air conditioner may freeze: 1. Faulty expansion valve: The freezing of the low-pressure pipe in a car air conditioner is most likely due to a faulty expansion valve, which fails to sense the real-time temperature of the low-pressure pipe. At this time, if the temperature is too low, the low-pressure pipe will inevitably freeze (the opening of the expansion valve cannot be adjusted lower). However, in most cases, this issue cannot be repaired, and a new expansion valve needs to be replaced. 2. Failed evaporator temperature sensor: It is important to know that this component is used to detect the surface temperature of the evaporator and then input the data to the automatic air conditioning control unit. When the temperature drops below 2°C, the air conditioner will stop operating, leading to frost or ice formation. Naturally, if the evaporator temperature sensor fails, it cannot detect the corresponding temperature data, resulting in the freezing of the low-pressure pipe. In this case, a new sensor needs to be replaced.
