Automotive urea solution falls under the catalyst classification in the tax classification code. Introduction to Automotive Urea: The SCR (Selective Catalytic Reduction) solution holds significant advantages in the National IV diesel vehicle exhaust emission treatment system, and automotive urea is an essential additive for the SCR solution. With the gradual implementation of the National IV emission standards for diesel vehicles in various cities, the demand for automotive urea may experience a surge. Current Development Status: The SCR system includes a urea tank (containing diesel exhaust fluid) and an SCR catalytic reaction tank. The operation process of the SCR system is as follows: when nitrogen oxides are detected in the exhaust pipe, the urea tank automatically sprays diesel exhaust fluid. The diesel exhaust fluid and nitrogen oxides undergo a redox reaction in the SCR catalytic reaction tank, producing non-polluting nitrogen and water vapor that are then discharged.

From an owner's perspective, diesel exhaust fluid (DEF) is a core additive category in diesel vehicle emission control systems, specifically used in vehicles equipped with SCR systems. It converts nitrogen oxides into harmless water and nitrogen. I have to refill it regularly, otherwise the vehicle will experience speed limitations or even become immobile, which is quite annoying. In practice, it's very convenient to use—just buy AdBlue from the supermarket and pour it into the tank, but avoid using household urea as it may damage the system. It's recommended to check the fluid level every 5,000 kilometers to save on costs. I've found that this stuff is crucial for environmental protection, helping to reduce harmful gas emissions and supporting air purification efforts. Also, pay attention to storage conditions—don't let it degrade in high temperatures, as this can affect its effectiveness.

In the environmental protection circle, automotive urea is definitely a star product in the category of green energy. It is an emission reduction agent specifically developed for diesel vehicles, with its core function in SCR technology. As someone who cares about ecology, this product converts exhaust gases into harmless substances, directly reducing the risk of smog and complying with modern regulations like Euro VI standards. If you don't add it during daily driving, the vehicle will trigger an alarm and affect performance, so it's best to develop the habit of timely replenishment. Compared to gasoline vehicle additives, it focuses more on sustainability, and it's being promoted globally as a cost-saving and earth-friendly solution. Choosing reputable brands like AdBlue helps avoid counterfeit products, making life easier and more economical for us drivers.

Is it necessary to apply film to the sunroof?

No. After applying film to the sunroof, the increased glass thickness may, if not installed properly, lead to difficulties in opening and closing the sunroof and affect its sealing performance. Here are some additional details: 1. Reasons: The primary purpose of applying film is to block UV rays and provide heat insulation, as well as to prevent injuries from shattered glass. However, sunroofs generally do not require film, as most sunroof glass already offers good heat insulation. If the sunroof is used infrequently, the sunshade can effectively block sunlight. 2. The role of a car sunroof: In summer, especially when the car is parked under the scorching sun, the temperature inside the car can become extremely high. The best way to cool down is to open the windows for ventilation, allowing air to circulate. If the car has a sunroof, air exchange inside the vehicle will be faster. Using this method cools the car 2-3 times faster than using the air conditioning and also saves fuel.

What are the differences between multi-point fuel injection and direct injection?

The following are the differences between multi-point fuel injection and direct injection: 1. Different definitions: Multi-point fuel injection refers to the process where gasoline fuel is injected into the intake manifold during the operation of a gasoline engine, controlled by a specific sequence of commands from the control program and executed by electronic fuel injectors. Direct injection, on the other hand, involves injecting fuel directly into the cylinder to mix with the intake air. 2. Different development speeds: The application of direct injection technology represents a significant attempt by people, and it is gradually replacing multi-point fuel injection. Moreover, the development of direct injection technology is progressing rapidly, with major automakers competing to research this technology, achieving quite remarkable results. Currently, Volkswagen is one of the automakers that has achieved relatively mature direct injection technology. 3. Different levels of fuel efficiency: Direct injection allows for a more balanced fuel injection compared to multi-point fuel injection vehicles, enabling more complete combustion of fuel during engine operation. This is an area where multi-point fuel injection vehicles can never match.

What is the standard tire pressure for the Haojue 125 scooter?

The front tire pressure should be maintained at 2.0 bar, and the rear tire pressure should be maintained at 2.5 bar, as the average pressure for all four tires of the vehicle is around 2.2 bar. Each tire has a maximum pressure limit, and exceeding this specified value can lead to the risk of a tire blowout. Conversely, if the tire pressure is too low, the tire may wear out prematurely. Therefore, tire pressure must be adjusted in combination with the maximum pressure value of the tire's rating. Below is more related information: 1. Types of tires: There are various types of tires, including high-performance racing slicks, which can effectively prevent tire slippage. If conditions permit, you may opt for racing slicks. If conditions are limited, you can choose anti-skid tires, which feature larger tread patterns to enhance grip. 2. Installing snow chains: In special road conditions, such as icy or snowy surfaces, snow chains can be installed to improve tire grip and prevent slippage. However, this method is only suitable for specific road conditions. Using snow chains on regular roads, while providing anti-skid benefits, will noticeably increase vehicle vibration and limit speed.

Which cities have implemented the China VI emission standards?

The following 9 provinces and municipalities have officially confirmed the early implementation of the China VI standards, which took effect from January 1st. These cities are Beijing, Tianjin, Hebei, Shandong, Shanxi, Henan, Guangzhou, Shenzhen, and Hainan. Additional information: 1. The implementation of China VI is divided into two phases: China VIa and China VIb. China VIa serves as a transitional phase from China V, with emission standards further improved based on China V, while China VIb represents the true China VI standard, the most stringent emission standard in history, imposing stricter requirements and limitations than Euro VI in many aspects. 2. It should be noted that the China VI standard is formulated based on international standards and is currently one of the most stringent emission standards globally, reaching the level of EU current vehicle fuel standards, with some indicators even surpassing EU standards. Compared to the currently implemented China V standard, China VI not only unifies gasoline and diesel standards but also introduces more requirements in eight areas, including particulate emission limits, test cycles and procedures, emission warranty periods, real-world driving emissions, and onboard diagnostics, making it the most stringent domestic emission standard. This poses direct challenges for automakers, the engine industry, component manufacturers, and after-treatment plants, primarily in terms of technological upgrades.

What's the situation when the car won't start but the dashboard lights are on?

When the dashboard lights are on but the car won't start, the most common fault issues are insufficient battery power or engine problems. Such issues require professional instrument repair at a 4S shop. Insufficient battery power is a frequently encountered phenomenon. If the dashboard lights are on, it indicates that the battery still has some power, but not enough to start the engine. The dashboard lights being on shows that the battery has some power left, and the key can still be turned, but the power is insufficient to start the engine. When turning the key, you may encounter the following phenomena: 1. Severe power loss, with no response at all when turning the key (in this case, the dashboard might not light up). 2. During startup, the dashboard flickers, accompanied by a "clicking" sound, which is a very standard sign of battery power loss, and the starter shows no response. 3. The dashboard flickers, and you can hear the starter turning, but it operates weakly, which is a milder sign of power loss, but it still makes it difficult to start the car. This is a battery issue. If the battery hasn't been replaced in over 3 years, it should be replaced promptly; otherwise, frequent difficulties in starting the car may occur.

How to Use Hazard Warning Lights When Parking a Manual Transmission Car?

Generally, there is a button with a red triangle symbol located on the center console. Pressing this button will activate the vehicle's hazard warning lights. It is important for drivers to note that these lights should only be used in relatively urgent situations. Hazard warning lights, also known as emergency flashers or hazard lights, serve to alert, warn, and indicate during accidents or other emergencies. When a vehicle encounters an emergency and must stop by the roadside, the hazard lights should be turned on, and a triangular safety warning sign should be placed at a certain distance behind the vehicle. However, if the hazard lights are turned on while waiting for someone in urban areas where short stops are allowed, it constitutes misuse. In the event of a traffic accident where the vehicle cannot be moved to a safe area, the driver should immediately activate the hazard lights to signal danger to other road users, call the police, and while waiting for rescue, all occupants should exit the vehicle and move to a safe location. According to relevant traffic laws, on regular roads, hazard lights may only be used in conjunction with fog lights during foggy conditions. In other weather conditions such as rain, snow, or sandstorms, hazard lights must not be used while driving on regular roads.
