For cities that have already implemented the National 6 emission standards, vehicles meeting the National 5 emission standard cannot be licensed. Cities where National 5 vehicles cannot be licensed include: Beijing, Tianjin, Hebei, Shandong, Shanxi, Henan, Guangzhou, Shenzhen, Hainan Province, etc. Policies in some regions may change, so it is necessary to refer to local regulations before licensing a National 5 vehicle. It is recommended to consult the local vehicle management office first. Cities where National 5 vehicles can be licensed include: Guangdong (except Guangzhou), Jiangsu (except Nanjing), Zhejiang (except Hangzhou), Sichuan (except Chengdu), Fujian, Guangxi, Ningxia, Hunan, Hubei, Xinjiang, and Yunnan, etc.

What Causes Severe Shaking When Slowly Releasing the Clutch in First Gear?

Reasons for car shaking when slowly releasing the clutch: Uneven pressure distribution in the car's clutch, incorrect pressure position; or the clutch pressure spring is too strong; oil contamination or breakage of the driven disc lining; bending of the main or driven disc, inconsistent height of the release levers. The following are details about the clutch: Function of the Clutch: The role of the clutch pedal switch is to ensure smooth starting of the car, achieve smooth gear shifting, and prevent overload of the transmission system. The switch on the clutch pedal is a normally closed switch. When the clutch is depressed, the switch opens, and the engine control unit does not receive a signal from the clutch, indicating that the engine connection is to be disconnected. Therefore, it reduces the ignition advance angle and decreases fuel injection for power reserve. Working Principle of the Clutch: The driving and driven parts of the clutch transmit torque through the friction between contact surfaces, or use liquid as a transmission medium (hydraulic coupler), or magnetic transmission (electromagnetic clutch), allowing temporary separation and gradual engagement, while permitting mutual rotation of the two parts during transmission.

What does d+m+ mean?

M+ means upshifting, while M- means downshifting. The M1/M2/M3 displayed on the instrument panel represent manual mode gears 1/2/3 respectively. The number of gears in M mode depends on the automatic transmission's gear count - for example, a 7-speed M mode has 7 gears. Below are details about M mode: Introduction to M mode: M mode is the manual mode in automatic transmission vehicles. When shifted to M mode, you can manually control the transmission's upshifts or downshifts without needing to depress the clutch, and the engine won't stall - just like regular automatic transmission. Usage of M mode: M mode is particularly useful during overtaking, uphill/downhill driving, slippery road conditions (rain/snow), cornering, and high-speed driving. For example, using m- to downshift during overtaking provides higher torque, allowing the vehicle to accelerate quickly.

What does the P2177 trouble code mean?

P2177 trouble code means: The system's air-fuel mixture is too lean when leaving idle, causing the mixture to be too lean when accelerating. Possible causes include fuel line blockage, malfunctioning mass air flow sensor, etc. P2177 trouble code meaning: It indicates that the closed-loop adaptive learning value for air-fuel ratio has exceeded the upper limit. The air-fuel ratio refers to the mixture ratio of fuel to air. Closed-loop adjustment means that under non-rapid acceleration and non-warm-up conditions, the oxygen sensor sends signals to the ECU to adjust fuel injection. Causes of P2177: This refers to the electronic control unit (ECU) adjusting fuel delivery by increasing or decreasing the injector opening time to achieve the optimal air-fuel ratio (14.7:1 air to fuel mass ratio). A too rich mixture means excessive fuel delivery, while a too lean mixture means insufficient fuel delivery. System too lean indicates relatively low fuel quantity (compared to intake air volume). Possible causes include: air leaks downstream of the mass air flow (MAF) sensor, PCV system leaks, faulty oxygen sensor, exhaust leaks near oxygen sensor, EGR leaks, dirty MAF sensor, clogged fuel injectors, insufficient fuel supply from fuel pump, etc.

What are the impacts of a car not being able to perform OTA upgrades?

The impacts of a car not being able to perform OTA upgrades are: it increases the risk of factory recalls occurring over several months. It will raise the recall costs caused by software defects. Rapidly fixing system defects: Traditional cars may develop software system defects during user driving verification, and the only solution for such situations is for the car manufacturer to initiate a recall program. After users receive the recall notice, they return to the dealership for a unified operating system upgrade. Rapid iteration and improvement of products and user experience: Due to the advanced hardware configuration in product design, intelligent connected vehicle operating systems can continuously unlock new features for car owners through successive OTA upgrades, enhancing product experience, enabling rapid iteration, and providing higher-quality service programs. This truly allows car owners to experience what it means to 'always drive a new car.'

Why does the motorcycle stall when the choke is turned off?

Motorcycle stalling immediately after turning off the choke is likely caused by insufficient fuel supply or an overly lean air-fuel mixture. Check the fuel tank level: When the choke is open, the air-fuel mixture becomes richer, allowing the engine to start. If the motorcycle stalls as soon as the choke is turned off, this is basically the problem. You can check the fuel tank level and the carburetor. Carburetor cleaning: During normal operation, the choke should be open. In cold weather, you need to close the choke to make starting easier. If the motorcycle hasn't been ridden for a long time, the carburetor may get clogged. It's recommended to take it to where you bought it and have a mechanic disassemble and clean it. Before leaving the motorcycle unused next time, close the fuel tank valve and drain the carburetor to prevent this issue.
