Navigation screen displaying colored horizontal or vertical stripes is usually caused by screen damage or wiring issues. Here are the relevant explanations: 1. Poor wiring contact: It is necessary to promptly check whether there are loose connections in the wiring. Simply reconnect the loose parts properly. 2. Aging power signal cable: Try replacing it with a new one. 3. Prolonged screen usage: This can cause the power supply module to malfunction, requiring inspection or replacement at a 4S shop. 4. Defective circuit design: This issue is beyond personal troubleshooting capabilities, so it's necessary to visit a repair shop for inspection, repair, or direct replacement.

Can China 5 vehicles still be registered after the implementation of China 6 standards?

After the implementation of China 6 standards, China 5 vehicles can no longer be registered. The China 6 standard refers to the National Sixth Stage Emission Standards for Motor Vehicles, which is divided into two phases: 6A and 6B. Compared to China 6A, China 6B imposes stricter requirements on the emissions of carbon monoxide, non-methane hydrocarbons, nitrogen oxides, and PM fine particulate matter. Automobile emission standards refer to the harmful gases emitted from vehicle exhaust, such as carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter. To curb the generation of these harmful gases and encourage automobile manufacturers to improve their products to reduce the source of these emissions, relevant automobile emission standards have been established.

What is the function of an engine fuel injector?

An engine fuel injector mainly consists of three parts: the starting circuit, the cold fuel injector, and the thermal time switch. The function of the cold start fuel injector is to spray fuel into the intake manifold during a cold engine start to enrich the air-fuel mixture and improve the engine's cold start performance. The cold start fuel injector is also known as an auxiliary fuel injector or cold start electric valve, enhancing the engine's low-temperature starting performance. The advantages and disadvantages of the cold start fuel injector are as follows: 1. Advantages: It can to some extent improve the difficulty of engine cold starts. 2. Disadvantages: Since the cold start fuel injector sprays fuel into the intake manifold, there is a drawback of uneven fuel supply to each cylinder.

What is the ground clearance of the Volkswagen Variant?

The ground clearance of the Volkswagen Variant is approximately 170mm. Here is some information about the Variant's ground clearance: 1. Minimum ground clearance: The Variant's minimum ground clearance is around 170mm. This measurement is neither good nor bad, but rather depends on requirements. Generally, a higher minimum ground clearance ensures better passability, while sports cars focused on performance prioritize handling and stability with lower clearance. 2. Ground clearance range: For sedans, the minimum ground clearance typically ranges between 110mm to 150mm. A larger ground clearance (over 130mm) provides better passability but poorer high-speed stability, whereas a smaller clearance (below 110mm) offers better high-speed stability but worse passability. Currently, models equipped with air suspension can automatically adjust ground clearance, effectively meeting both passability and high-speed stability requirements.

What to Do When the Car Air Conditioner Breaks Down?

When the car air conditioner breaks down, the owner can first perform a self-inspection to check if the air intake vent is closed; whether the condenser coils and fins are clean; whether there is sufficient refrigerant in the air conditioning system; whether the blower motor is functioning properly; whether the blower channel is blocked; and whether the air intake filter is clogged. If the issue cannot be resolved on your own, it is recommended to seek professional help. During the hot summer months when using the air conditioner, try to avoid running it for extended periods. Some car owners often keep the air conditioner on continuously after getting in the car, but prolonged use can cause excessive pressure on the condenser, leading to wear and tear on the cooling system. This is because the air conditioner is a significant burden on the engine, which itself is a heat-generating component.
