The function of the urea ambient temperature sensor is to monitor the temperature of the urea in the urea tank. It integrates a cooling water heating pipe, which is used to heat and thaw the system in cold regions. It can heat the urea solution to prevent urea crystallization in cold weather, which could cause system failure and render it inoperable. Below are the functions of automotive urea and the impacts of not using urea in vehicles: Functions of Automotive Urea: Process exhaust gases to reduce pollutants in the emissions, optimize engine performance, and improve fuel consumption. Impacts of Not Using Urea in Vehicles: Excessive emissions, causing environmental pollution; chemical substances in the vehicle system may oxidize, the urea nozzle may become clogged, leading to the entire system being scrapped; reduction in vehicle power.

Is Heavy Steering Wheel a Common Issue with the Excelle?

Heavy steering wheel in the Excelle may be caused by issues with tire pressure. New cars typically come with tire pressure close to 3.0, while the normal level should be around 2.4. The Excelle has a tire pressure label on the driver's side front door frame, indicating the original tires and corresponding tire pressure. If the tire pressure is too low, the steering wheel may feel heavier. Below are methods to check for heavy steering wheel in the Excelle: 1. Inspect various aspects for issues: Additionally, check if there is soundproofing cotton or dirt wrapped around the steering gear, and verify if there are any problems with the electronic power assist. The power assist adjusts according to speed. 2. Electronic power steering system: It is normal for the electronic power steering system to become heavier at high speeds and lighter at low speeds, as this is a safety protection feature.

What are the types of motorcycle license tests?

The "Regulations on the Application and Use of Motor Vehicle Driving Licenses" classify motorcycle licenses into three types: D, E, and F. Among them, D is for ordinary three-wheeled motorcycles, E is for ordinary two-wheeled motorcycles, and F is for light motorcycles. Permitted vehicles for D license: Can drive ordinary three-wheeled motorcycles (with an engine displacement greater than 50ml or a maximum design speed greater than 50km/h) and E. Permitted vehicles for E license: Can drive ordinary two-wheeled motorcycles (with an engine displacement greater than 50ml or a maximum design speed greater than 50km/h) and F. Permitted vehicles for F license: Can drive light motorcycles (with an engine displacement less than or equal to 50ml and a maximum design speed less than or equal to 50km/h).

What is the difference between 110v and 220v?

Differences are as follows: 1. Different voltages: The biggest difference between 110v and 220v is the voltage. 220V transmission consumes less electricity than 110v, and under the same wire conditions, it can effectively reduce energy loss compared to 110V. The wire cross-section for 220v transmission of the same power is reduced, saving a large amount of non-ferrous metals. 2. Transmission distance: 220V voltage has smaller losses in long-distance transmission, effectively reducing energy loss compared to 110V, resulting in lower electricity costs. 3. Wire cross-sectional area: For transmitting the same amount of electricity under the same transmission loss conditions, the wire cross-sectional area used for 220V voltage is half that of 110V, saving wire metal materials.

What is the normal driving speed for a sedan?

The normal driving speed for a sedan depends on different situations. In urban areas, it should be between 30-60 kilometers per hour, while on highways, it generally ranges from 80-120 kilometers per hour. In ordinary urban areas, the speed is approximately 60-80 kilometers per hour. Driving in urban areas: Due to heavy traffic and pedestrians, the driving speed should not be too fast. It is generally recommended to maintain a steady speed of around 40 km/h. In special circumstances, the speed can be adjusted according to the actual situation. Driving on highways: Since the road is relatively clear and highways are designed for fast traffic, the driving speed should not be too slow. Therefore, the driving speed should be maintained between 80-120 kilometers per hour. Ordinary urban areas refer to national roads adjacent to urban areas where pedestrian traffic is not heavy. In such areas, the driving speed can be kept between 60-80 kilometers per hour.

What is the difference between Group IV and Group III oils?

Group IV and Group III oils differ in base oil composition, resistance to degradation, and oil film performance. Difference in base oil composition: Group IV base oils are synthetically produced and outperform Group III full synthetic base oils in overall capabilities. Difference in resistance to degradation: Group IV oils typically enter the degradation phase only after 10,000 kilometers, and the degradation is not very noticeable. In contrast, Group III full synthetic oils begin to degrade at 4,000-5,000 kilometers. Difference in oil film performance: Group IV full synthetic oils have extremely stable oil film performance, maintaining good shear resistance with long molecular chain structures that are difficult to break. Group III full synthetic oils, however, show relatively inferior stability in oil film performance.
