What Happens If a Truck Doesn't Use Urea?

Truck's reaction to not using urea is as follows: 1. Excessive emissions: Adding urea is mainly to reduce the emission of carbon-nitrogen compounds. Without urea, emissions will exceed the standard, causing pollution and environmental impact. 2. Urea nozzle clogging: If urea is not used for a long time, the chemicals in the diesel vehicle system will quickly oxidize, and the urea nozzle will also clog, rendering the entire system useless. 3. Reduced power performance: Due to the OBD's torque limitation function, vehicles without urea will experience a decrease in power performance. Domestic vehicle urea is mainly derived from purified industrial urea, and its main principle is: 1. At a temperature of 70-75°C, urea hydrolyzes in an aqueous solution; 2. At a temperature below 30°C, urea recrystallizes from the aqueous solution; 3. Each hydrolysis and crystallization cycle significantly improves its purity. Generally, using industrial-grade urea for one hydrolysis and crystallization cycle can meet the vehicle urea standard requirements, with an output ratio of 1.5:1.

Can I drive on the highway with a newly obtained driver's license?

Newly licensed drivers in the probationary period are not allowed to drive on the highway alone. If a driver in the probationary period needs to drive on the highway, they must be accompanied by a driver who has held a driver's license for the same or a higher class of vehicle for more than three years. The accompanying driver should sit in the front passenger seat to provide guidance. Article 22 of the Implementation Regulations of the Road Traffic Safety Law stipulates that the validity period of a motor vehicle driver's license is six years, and the first 12 months after a driver initially obtains a license is the probationary period. During this period, a probationary driver must display a uniform probationary sign on the rear of the vehicle. Failure to display the probationary sign as required will result in a fine of 200 yuan.

Who Decides the Vehicle Damage Assessment Amount?

Vehicle damage assessment amounts can be determined through mutual voluntary negotiation between both parties, or by jointly commissioning a third party (legally established appraisal institutions or legally qualified experts) to evaluate and appraise the insurance incident. In cases where both parties cannot reach an agreement, the amount can be legally determined through litigation or arbitration procedures. Vehicle damage assessment involves a comprehensive analysis of automobile collision and accident scenes based on automotive construction principles, utilizing scientific and systematic professional inspection, testing, and surveying methods. It employs vehicle damage estimation materials and repair data to scientifically and systematically estimate the pricing for collision repairs. Vehicle damage assessment includes assessments for scratch incidents, undercarriage damage incidents, collision incidents, as well as fire and flood damage incidents.

How to Conduct the Annual Inspection for a New Car After 2 Years?

For the annual inspection of a new car after 2 years, the vehicle owner needs to personally bring the following documents to the local vehicle management office or traffic police department to apply for the annual inspection sticker: 1. Vehicle registration certificate (original and duplicate); 2. ID card of the vehicle owner; 3. Compulsory traffic insurance policy for the vehicle; 4. Proof of payment or exemption for vehicle and vessel tax. If the inspection is delegated to someone else, the original ID card of the delegate and a written authorization signed by the vehicle owner are also required. For small cars and blue-plate minivans, the first six years after registration require an inspection every two years; after six years, it becomes an annual inspection; after fifteen years, it becomes a semi-annual inspection. For trucks, an annual inspection is required after registration, and after ten years, it becomes a semi-annual inspection. The documents needed for the vehicle annual inspection include: the vehicle registration certificate, a valid compulsory traffic insurance policy, and the vehicle and vessel tax receipt.

Why does the oil light come on when there is sufficient oil?

The reasons why the oil light comes on despite sufficient oil: 1. The engine temperature is too high, which can thin the oil, causing it to leak excessively through the gaps and leading to a drop in oil pressure; 2. If components of the oil pump are damaged or excessive gaps occur due to wear or improper assembly, the oil pump may fail to deliver oil or deliver insufficient oil; 3. Incorrect clearance between the crankshaft and bearings—too tight will increase oil pressure, while too loose will decrease it; 4. Blockages in the oil filter or oil pickup can also reduce oil pressure; 5. A faulty or malfunctioning pressure relief valve—if the spring in the main oil passage's relief valve is fatigued, improperly adjusted, or if the valve seat and ball are worn or stuck open due to debris, the return oil volume increases significantly, leading to a drop in main oil passage pressure; 6. Incorrect oil selection—using the wrong oil or an inappropriate viscosity grade can result in excessive leakage due to low viscosity, lowering oil pressure; 7. Oil leaks or blockages in the oil lines.

What is the speed limit on the He-Da Expressway?

The speed limit regulations on the He-Da Expressway are as follows: 1. For roads with 2 lanes in the same direction, the minimum speed in the left lane is 100 kilometers per hour; 2.

The maximum speed for small passenger vehicles on the expressway must not exceed 120 kilometers per hour; other motor vehicles must not exceed 100 kilometers per hour; motorcycles must not exceed 80 kilometers per hour. Expressways should clearly mark the speed limits for each lane, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour.

Within how many days must the damage assessment be conducted after filing a claim?

There is no strict time limit for conducting a damage assessment after filing a claim. However, after reporting a car insurance claim, you should not leave the accident scene and must wait for the insurance company to send someone to assess the damage. The timing is usually influenced by the following factors: 1. The extent of the vehicle damage; 2. The efficiency of the insurance company; 3. The location of the accident. So far, insurance companies do not have a rigid requirement for the time frame of damage assessment after reporting an accident, so even if it exceeds 48 hours, the assessment can still proceed normally without any impact. However, there is a mandatory requirement for the time of reporting an accident. According to insurance regulations, the policyholder must report the accident within 48 hours of its occurrence.
