To identify the national emission standard on the vehicle license, check the vehicle model number: if it starts with 'bh', the suffix 'w' or 'x' indicates China III emission standard, 'y' indicates China IV, 'v' indicates China V, and 'vi' indicates China VI. Other methods to check the vehicle's emission standard include: 1. Review the motor vehicle conformity certificate; 2. Check the vehicle's accompanying documents for the emission standard in the vehicle information section; 3. Check the conformity certificate; 4. Visit the official motor vehicle environmental protection website for inquiries; 5. Inspect the vehicle's environmental protection label. The 'National' emission standards refer to China's phased vehicle emission standards, from China I to China VI, marked by the symbols i, ii, iii, iv, v, and vi respectively.

I remember driving for over a decade now, and when it comes to checking emission standards, there's no direct label on the vehicle license indicating the national standard level. The main method is to check the registration date to deduce it. My old car last year was registered in 2008, and after checking online, I found that the National III standard had just been implemented, so I concluded it was a National III vehicle. The newly purchased car was registered in 2019, likely meeting the National VI standard. The vehicle license contains the vehicle model and engine number, which, although a bit vague, can be reliably checked against the date on the environmental protection bureau's official website or app. Don’t forget that restricted zones enforce strict rules, and vehicles below National III may incur fines, so regularly checking the vehicle’s exhaust emission reports is more reassuring. In short, don’t rely solely on the vehicle license; combining other information gives a complete picture and saves unnecessary trips.

Hi, as a regular car owner, I just helped a friend check this. The emission standard isn't separately marked in the vehicle license. Just flip to the registration date section - for example, his car was registered in 2012, and checking the standard timeline shows China IV was implemented that year, so that's basically confirmed. If the date is too old or new, matching the engine model can give you a rough idea too. But for accuracy, I recommend downloading a car app and entering the vehicle model - the system will automatically match the emission standard. Keep your vehicle license safe and don't mess with it. A related tip is to do regular environmental tests - the label stuck on your car makes it more obvious and saves you trouble during traffic police checks.

Which has a longer lifespan, Yuasa or Varta?

Yuasa. Generally, Varta batteries have a lifespan of around 3-4 years, while Yuasa offers a longer service life. Below is relevant information about car batteries: Introduction: A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Typically, the term 'battery' refers to lead-acid batteries, which are mainly made of lead and its oxides, with sulfuric acid solution as the electrolyte. Battery maintenance: Avoid parking the car in open parking lots for extended periods. If long-term parking is necessary, remove and take the battery to prevent freezing damage. In winter, car engines are harder to start; each attempt should not exceed 5 seconds, with intervals of at least 15 seconds between attempts. If the engine fails to start after multiple attempts, check other aspects such as the electrical circuit, ignition coil, or fuel system. Avoid continuous, uninterrupted starting attempts, as this can cause the battery to over-discharge and burn out.

Are there charging ports on Harmony Express trains?

There are various models of Harmony Express trains, and the locations of charging sockets are also set in different places. Some charging sockets are located overhead, while others are positioned under the seats. For example: the power socket on CRH380A trains is located under the seats. On the other hand, the power socket on CRH1A trains is located above the windows (under the luggage rack). Here is some additional information about other charging locations: On sleeper trains: The most unique is the CRH2E longitudinal sleeper train, which differs from traditional sleeper trains with its longitudinally arranged berths parallel to the direction of the train. Each berth is by the window and independent, with a charging socket and USB port at the "headboard" of each berth. Traditional transverse sleeper trains: Similar to the power sockets in second-class seats, the location depends on the model, with sockets usually found under the small table in the middle of the berth or at the "foot" of the bed. If there is no power socket at your seat: You can find charging ports at the large luggage storage areas or near the washbasins. Additionally, charging ports can also be found on the walls in front of the first row of seats and behind the last row of seats in each carriage.

What are the reasons why a gasoline engine won't start?

Here are the reasons why a gasoline engine won't start: The vehicle battery is dead or damaged: It may be due to the battery reaching the end of its lifespan, or damage caused by the vehicle being parked for an extended period. Battery depletion could occur when the ignition switch is turned on without starting the vehicle, with the headlights left on for a long time, or continuous use of high-power entertainment systems like audio systems. Excessive carbon buildup in the vehicle engine: This can also cause difficulty in ignition, possibly related to poor fuel quality or poor sealing of the valve ports. Ignition system failure: Poor connections in the low-voltage circuit or leakage in the high-voltage wires can cause this issue. Severe aging of the starter motor: This means the vehicle has been in use for too long, leading to gradual aging of the starter motor, resulting in weak starting power and failure to ignite. Extremely low temperatures: In cold winter conditions, the viscosity of the engine oil changes, causing the engine speed to be too low to initiate ignition.

How to Test the Jetta Water Temperature Gauge?

Jetta does not have a water temperature gauge, only a water temperature warning light located on the car's dashboard. Below are the reasons why the water temperature warning light may come on: 1. Coolant leakage can cause its temperature to rise: At this time, check if there is any leakage of coolant. If there is, the leaking pipes should be repaired quickly. If not, the same brand of coolant should be added promptly. Adding water is not recommended, especially in winter, as it can dilute the coolant even if it doesn't cause a malfunction. 2. Problem with the radiator fan: A faulty radiator fan can prevent heat generated during high-speed operation from being transferred to the antifreeze in time, affecting heat dissipation and leading to an increase in antifreeze temperature, causing issues like overheating. If this happens while driving, reduce speed first. Check if the issue is with the fan, and if so, repair it promptly. Don't wait until overheating occurs to fix it. 3. Problem with the circulation water pump: If the water pump malfunctions, the water circulation on the engine's heat-conducting side cannot proceed normally. This leads to a failure in the engine's cooling system, resulting in overheating. It's crucial to detect and resolve this issue early. Generally, water pump problems may be due to seized bearings or damaged impellers.

What is the fuel consumption of Toyota?

Toyota Land Cruiser 4.0L version has a comprehensive fuel consumption of 13.3L/100km according to the Ministry of Industry and Information Technology. The fuel consumption of a car varies slightly depending on each person's driving habits and skills. If the driving habits are relatively steady, the fuel consumption will be lower. If you usually prefer aggressive driving, overtaking, and other high-speed operations, the fuel consumption will increase appropriately. Here are some methods to reduce fuel consumption: Check the air conditioning system in summer: Air conditioning malfunction is a significant reason for high fuel consumption. If the air conditioning cooling effect is poor, it will increase the fan speed and lower the temperature to achieve a cooling effect. Frequent sudden braking: Frequent sudden braking is the main reason for high fuel consumption in cars. While ensuring safe driving, make full use of the vehicle's inertia. Small-displacement cars should not use air conditioning too aggressively: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately after getting in the car. First, open the windows, set the fan to a higher speed without turning on the air conditioning to expel the hot air inside the car. Wait until the vehicle has cooled down moderately before turning on the air conditioning.
