Why Do Diesel Engines Need Urea?

To reduce harmful nitrogen oxides in exhaust gases into nitrogen and water. Below is relevant information: Diesel Engine: A diesel engine is an internal combustion engine that generates power by burning diesel fuel. Invented in 1892 by German engineer Rudolf Diesel, these engines are called Diesel engines in honor of their inventor. Urea: One of the simplest organic compounds, urea is the main nitrogen-containing end product of protein metabolism in mammals and some fish species. As a neutral fertilizer, urea is suitable for various soil types and plants.

What are the precautions when picking up a new car?

The precautions for picking up a new car are as follows: Check the vehicle's exterior: To better inspect the condition of the new car, consumers usually don't have professional tools, so the only method is to observe with the naked eye. Check for scratches and wear on the paint by parking the vehicle in an outdoor area with sufficient light, then examine whether the paint is even. Check the production date of the glass: The number represents the most recent production year, and the dots represent the production month. If the dots are on the left side of the number, it indicates production in the first half of the year; subtract the number of black dots from 7 to get the specific month. If the dots are on the right side of the number, it indicates production in the second half of the year; subtract the number of black dots from 13 to get the specific month. If the production date of the window glass is too far from the new car's production date, a year or more, it is highly likely that the window glass has been replaced.

Is deducting 11 points and 9 points the same for a B2 license?

b2 deducting 11 points and 9 points is the same, with identical handling results. The relevant details are as follows: Deducting 11 points and 9 points: Both require attending a seven-day study session on road traffic safety laws at the vehicle management office after the points are recorded. After passing the exam, the motor vehicle driver's license will be reissued, and the points on the license will be restored before it can be used normally. Consequences of deducting 12 points: After deducting 12 points, the motor vehicle driver's license will be confiscated. A seven-day study session on road traffic safety laws and regulations is required, followed by an exam. After passing the exam, a downgrade procedure must be completed, and the license will be downgraded to C1. Then, the motor vehicle driver's license can be collected and used. When using it, special attention must be paid to the vehicle type to avoid traffic violations and illegal activities.

What is the difference between semi-synthetic and fully synthetic engine oil?

The difference between semi-synthetic and fully synthetic engine oil lies in the refining method of the base oil. The relevant details are as follows: Semi-synthetic engine oil: Semi-synthetic engine oil uses semi-synthetic base oil, which is a product refined from mineral oil through hydrocracking technology. It is a mixture of mineral oil and fully synthetic oil in a ratio of 4:6. The purity of semi-synthetic oil is very close to that of fully synthetic oil, but its cost is slightly higher than that of mineral oil, making it an ideal transitional product from mineral oil to synthetic oil. Fully synthetic engine oil: Fully synthetic engine oil is a high-grade product among engine oils. It is derived from ethylene and propylene dispersed from natural gas or gas in crude oil, which are then processed through complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules. Essentially, it uses the better components of crude oil, undergoes chemical reactions, and achieves the desired molecular structure under human control. The molecules of fully synthetic oil are neatly arranged, giving it a naturally strong resistance to external variables. Therefore, it has superior properties, with much better thermal stability, oxidation resistance, and resistance to viscosity changes compared to mineral oil and semi-synthetic oil.

Are Methanol Vehicles Considered New Energy Vehicles?

Methanol vehicles belong to the category of new energy vehicles. Here is the relevant introduction: Methanol Vehicles: Methanol vehicles are also a type of new energy vehicle. Methanol serves as an alternative fuel to gasoline, representing a new fuel energy source, thus classifying the vehicles as new energy vehicles. The emissions from methanol combustion are relatively environmentally friendly, aligning with the national concept of environmental protection, and should be strongly supported and promoted. New Energy Vehicles: New energy vehicles refer to those that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and innovative structures.

What Causes the Engine Warning Light to Illuminate After Accelerating?

After accelerating, the engine warning light may illuminate due to using the wrong fuel grade or poor fuel quality. Poor fuel quality can lead to incomplete combustion in the engine, which in turn causes excessive emissions. The emission system detects this and interprets it as an engine malfunction, triggering the engine warning light. The car engine is the power-generating unit of a vehicle, often referred to as the heart of the car, determining its power, fuel efficiency, stability, and environmental performance. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others.
