Automotive urea is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition consists of 32.5% high-purity urea and 67.5% deionized water. Additional information: 1. As environmental protection departments in various countries proposed further reduction of nitrogen oxide pollutants emitted by diesel engines (commonly known as the Euro IV standard in China), engine manufacturers began using SCR technology to meet environmental requirements. Diesel exhaust fluid is a necessary consumable in SCR technology. 2. Failure to load diesel exhaust fluid, or using fluid with insufficient purity or inferior quality, will cause the vehicle engine to automatically decelerate. Moreover, inferior quality diesel exhaust fluid can contaminate the catalyst in the SCR catalytic reaction tank, leading to serious consequences.

Is it normal for the engine to shake once or twice after shutting off?

It is normal for the engine to shake slightly at the moment of shutdown. This occurs because the fuel injection is interrupted when the engine is turned off, and the engine transitions from inertial motion to a complete stop. At very low RPM, shaking can occur. Additionally, when the engine shuts off, both the fuel and electrical systems cease operation, causing moving components inside the engine, such as the crankshaft and pistons, to come to an abrupt halt, resulting in vibrations. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a vehicle, also known as vehicle servicing. 2. Scope of car maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and more. 3. Purpose of car maintenance: The goal of car maintenance is to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent malfunctions, slow down deterioration, and extend the vehicle's lifespan.

How to Handle the Vehicle License for a Used Car?

Here is an introduction on how to handle the vehicle license for a used car: 1. Materials: First, prepare all the necessary materials for the used car transaction, including the vehicle license, vehicle registration certificate, vehicle purchase tax certificate, road maintenance fee receipt, insurance policy, vehicle and vessel usage tax certificate, and ID card. The used car transaction contract must be supervised by the industrial and commercial department, with both the buyer and seller holding a copy. The contract must be filed with the industrial and commercial department, and the vehicle change or transfer procedures can only proceed after filing. If any discrepancies are found in the relevant documents, it is recommended that the owner make the necessary changes in advance. 2. Related Notes: When purchasing a used car, pay attention to the vehicle's condition, such as the production date and mileage. The mileage can reflect how long the car has been driven, directly indicating its service life, and helps avoid unnecessary troubles during the transfer process.

What are the symptoms of a faulty tensioner pulley?

The symptoms of a faulty tensioner pulley mainly include: 1. The engine will experience timing chain skipping; 2. Disordered ignition and valve timing; 3. Engine shaking and difficulty in ignition; 4. Severe cases may result in failure to start the car; 5. After starting, the valve may be deformed. Additional information: 1. The tensioner pulley is a belt tensioning device used in the automotive transmission system. It mainly consists of a fixed housing, tensioning arm, wheel body, torsion spring, rolling bearing, and spring bushing. It can automatically adjust the tension according to the different tightness of the belt, ensuring the stability, safety, and reliability of the transmission system. 2. The tensioner pulley is a wear-prone part in automotive components. Over time, the belt can easily stretch. Some tensioner pulleys can automatically adjust the belt tension. Additionally, the tensioner pulley makes the belt run more smoothly, reduces noise, and prevents slipping.

Why does the Mazda Atenza make abnormal noises when turning at low speeds?

The reasons for abnormal noises when the Mazda Atenza turns at low speeds are as follows: 1. Friction between the steering column and the floor mat, which is a relatively common situation; 2. Low temperatures causing plastic components under the steering wheel to rub, resulting in abnormal noises that will disappear or reduce after the car warms up. This type of noise does not affect normal vehicle use; 3. Worn shock absorber pressure bearings, which can produce similar noises. It is recommended that the owner visit a 4S store as soon as possible to identify and resolve the noise issue. Below are the correct methods for steering: 1. Avoid turning the steering wheel while the vehicle is stationary. Try to steer only after the vehicle starts moving. Stationary steering should only be used occasionally in special circumstances, such as when maneuvering out of a tight spot. 2. After the vehicle is parked, return the steering wheel to the central position to avoid placing unnecessary load on the suspension system and tires. 3. When making a U-turn, try to avoid turning the steering wheel to its extreme limit.

Which is More Difficult for Manual Transmission: Subject 2 or Subject 3?

Subject 2 only requires following the steps to align points and lines, while Subject 3 tests the trainee's adaptability, introducing many uncertainties. Therefore, Subject 3 is more difficult. Below are the relevant details: 1. Subject 2: Subject 2, also known as the small road test, is part of the motor vehicle driver's license assessment and refers to the field driving skills test. For small vehicles C1 and C2, the test items include five mandatory components: reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curved path. 2. Subject 3: Subject 3 is also part of the motor vehicle driver's license assessment and refers to the road driving skills and safe driving knowledge test. The road driving skills test generally includes: preparation before starting, simulated light test, starting, driving in a straight line, gear shifting operations, changing lanes, and parking by the roadside.
