Automotive urea solution serves the following purposes: treating exhaust gases to reduce pollutants, optimizing engine performance, and improving fuel consumption. Vehicle urea is a colorless, transparent liquid stored in the urea tank. When sensors detect nitrogen oxides in the exhaust pipe, they automatically spray atomized urea solution, which mixes with nitrogen oxides. In the SCR (Selective Catalytic Reduction) reaction tank, a redox reaction occurs, producing and emitting non-polluting nitrogen and water. The consequences of not using urea in vehicles include: 1. Exceeding emission standards, causing environmental pollution; 2. Oxidation of chemical substances in the vehicle system, leading to clogged urea nozzles and rendering the entire system inoperable; 3. Reduced vehicle power performance.

What are the speed control driving techniques?

Speed control driving techniques are as follows: 1. Gear shifting timing: After starting, as long as road conditions permit, shift from low gear to high gear as soon as possible. 2. Low gear speed: When shifting from 1st gear to 2nd gear, avoid accelerating with a large throttle. That is, after starting, when the car's speed is similar to a walking pace, shift to 2nd gear. 3. Medium gear speed: When shifting from 2nd gear to 3rd gear, the throttle should not be too large, and the acceleration time should be slightly longer than when shifting to 2nd gear. 4. Adjustment gear speed: The transition from medium gear to adjustment gear, that is, shifting from 3rd gear to 4th gear, and from 4th gear to 5th gear.

Where to Brake at the Crosswalk in Subject 3?

Generally, you should tap the brake at the white diamond-shaped pattern, approximately 8-10 meters before the crosswalk. Below is a detailed introduction about it: 1. Introduction 1: Subject 3, which includes the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. 2. Introduction 2: It is the abbreviation for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's examination. 3. Introduction 3: The road driving skills test in Subject 3 generally includes: preparation before getting on the car, light simulation test, starting, driving straight, shifting gears, changing lanes, parking by the roadside, going straight through intersections, turning left at intersections, turning right at intersections, passing through crosswalks, passing through school zones, passing through bus stops, meeting oncoming vehicles, overtaking, making U-turns, and driving at night.

Why is the EV function limited?

EV function is limited due to a fault in the vehicle's high-voltage system. Here is some relevant information about EVs: 1. Popularity: Although pure electric vehicle technology in China is already very mature, there are still difficulties in achieving industrialization in the short term due to various reasons. Industry experts point out that the widespread adoption of charging stations is key to the industrialization of pure electric vehicles. At the same time, national industrial policies should provide a favorable application environment for pure electric vehicles to promote their industrialization process. 2. HEV: The full name of EV on hybrid vehicles is HEV, which stands for Hybrid Electric Vehicle. Hybrid power means the vehicle uses both gasoline and electric drive systems. The advantage is that when the vehicle starts and stops, it relies solely on the generator. The engine does not work until a certain speed is reached. Therefore, the engine can always maintain optimal working conditions, with good power performance and very low emissions. The source of electrical energy is the engine, and it only requires refueling.

What is the difference between trains starting with C and G

Here are the differences between the two: 1. C-starting trains: C-starting trains belong to intercity EMUs and ordinary trains, with a speed of 80-160 km/h. They mainly appear in large cities or economically developed provinces, primarily to facilitate travel for residents in surrounding cities. They are mostly concentrated in first and second-tier cities, connecting large cities with surrounding smaller cities to meet basic travel needs. C-starting trains run on ballastless tracks, meaning roads without stones or gravel. 2. G-starting trains: G-starting trains are high-speed trains with a speed of 250 km/h. They cover long distances and mostly appear for inter-provincial travel. There are routes from Guangdong to Beijing, connecting various provinces. High-speed train stations are mainly located in remote areas within provinces, with surrounding transportation networks radiating out.

Can I pass the subject one test without finishing over 1000 questions?

Most of the questions in subject one are common sense questions, and safety should always come first. Therefore, going through them carefully twice should be enough to pass. Here is a detailed introduction about it: 1. Traffic regulations and related knowledge: The full score is 100, and a score of 90 or above is considered passing (including 90). 2. Field driving: It is only divided into pass or fail. The test follows a 3+1 format, with three mandatory items and one optional item selected by the computer from seven items. 3. Road driving: Conducted on highways or simulated fields with actual vehicles. The full score is 100, with passing scores of 90 or above for large buses, 80 or above for large trucks, and 70 or above for other vehicle types.
