17-year-old cars comply with the China V emission standard. 'Guo Ji' refers to the National Motor Vehicle Pollutant Emission Standard, which is the exhaust emission standard for automobiles. The automobile emission standard specifies the limits for harmful gases emitted from vehicle exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, carbon smoke, etc. The China V emission control level is equivalent to the Euro 5 emission standard currently implemented in Europe. It imposes stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. The implementation of the China V standard promotes the improvement of domestic gasoline and diesel quality for vehicles, contributes to the reduction of pollutants from new vehicles, and improves the pollutant emission conditions of a large number of in-use vehicles.

I drive a 2017 Nissan model, which I remember complies with the China V emission standard. At that time, the China V standard was uniformly implemented nationwide, meaning the emissions of nitrogen oxides and particulate matter in the exhaust were strictly controlled. Emission standards affect vehicle registration and annual inspections; when purchasing, the 4S dealership provides an environmental label. Compared to older China IV vehicles, China V is more environmentally friendly and fuel-efficient, but not as advanced as the current China VI standard. If you come across cars manufactured in 2017 in the used car market, most are at the China V level. Owners can check the specific emission standard through the vehicle management office website or an OBD diagnostic tool to avoid misunderstandings. As policies become stricter, understanding emission standards helps with used car transactions and maintenance cost control.

What is the reason for failing the alternating high-low beam test in Subject 3?

Failing the alternating high-low beam test in Subject 3 is due to operating the flashing lights too quickly. Below are specific details about the alternating high-low beam test in Subject 3: 1. Precautions: When the driving test voice system announces overtaking or when there are no traffic signals, you can alternately use the high and low beams. You must turn on the corresponding lights within 5 seconds after the system finishes the announcement, neither answering too early nor delaying. 2. Instructions: During the lighting test, alternate between high and low beams when you hear voice prompts such as approaching a sharp curve, approaching a slope, approaching a humpback bridge, approaching a crosswalk, or approaching an intersection without traffic signal control. You must alternate the high and low beams at least twice.

How to Deal with Low Tire Pressure Warning?

Displaying low tire pressure can be addressed by: 1. Inflating the tires according to the manufacturer's recommended pressure values; 2. Inspecting the tires for bulges, cracks, cuts, punctures, or abnormal wear to promptly identify the cause of air leakage and prevent slow leaks; 3. Regularly checking tire pressure, as incorrect pressure can affect the tire's performance; 4. Using a car air pump to monitor and maintain proper tire pressure, ensuring safety by avoiding potential hazards. The reasons for displaying low tire pressure include: 1. Air leakage from the tire or valve stem; 2. Wheel rim deformation reducing the tire's sealing performance; 3. Uneven tire stress caused by long-term overloading of the vehicle; 4. Thermal expansion and contraction leading to insufficient tire pressure.

What Causes Fluctuating Idle Speed During Cold Start?

Here are the specific reasons for fluctuating idle speed during cold start: 1. Intake manifold leakage: When unauthorized air, fuel vapor, or exhaust gases enter the intake manifold, causing the air-fuel mixture to become too rich or too lean, resulting in unstable engine idle. 2. Excessive carbon buildup in throttle body: Carbon deposits in the throttle body and surrounding intake passages alter the air channel cross-sectional area, preventing the control unit from precisely regulating idle air intake. This also leads to improper air-fuel mixture and unstable idle. 3. Faulty intake system components: The engine intake system contains numerous actuators such as throttle motor, idle speed control valve, duty cycle solenoid valve, mass airflow sensor, and intake pressure sensor. Malfunctions in any of these components can cause unstable idle speed.

What does ESC mean on a car?

ESC on a car refers to the Electronic Stability Control system. When the ESC is activated, pressing and holding the ESC button can deactivate the Electronic Stability Control system. The Vehicle Stability Control system is an active safety system developed by Toyota, which significantly enhances vehicle handling safety and driving convenience. In emergency situations such as sharp turns, sudden acceleration, or hard braking, the system can quickly detect and take appropriate braking actions, such as individually controlling each wheel while reducing engine output to maintain vehicle stability. The Electronic Stability Control system is an extension of the Anti-lock Braking System (ABS) and Traction Control System (TCS) functionalities. It incorporates additional sensors like the yaw rate sensor, lateral acceleration sensor, and steering wheel angle sensor during vehicle steering. Through the ECU, it controls the driving and braking forces of the front, rear, left, and right wheels to ensure lateral stability during driving.
