This situation is most likely due to a system malfunction. Vehicle weakness, normal urea consumption: Use a diagnostic tool to read the fault code, indicating that the engine has exceeded the emission limit with no other faults. By removing the urea nozzle and performing an injection test with the diagnostic tool, no abnormalities were found. During the inspection, a large amount of urea crystals were found severely clogging the high-temperature catalytic pipe. The exhaust elbow pipe was removed for cleaning, and compressed air was used to clean the soot adhering to the ceramic surface of the catalytic converter. After replacing the urea solution, the test failure disappeared. Low urea pressure, high urea consumption: Fault symptom: The vehicle's instrument panel warning light frequently flashes. The fault code indicates low urea pressure and high urea consumption. The urea tank temperature is too high, causing urea to volatilize and be discharged from the exhaust port, crystallizing around the tank. Excessive crystallization at the exhaust port leads to blockage. Summary: During the operation of the urea system, severe vacuum suction in the urea chamber caused urea decompression blockage, resulting in a low urea pressure fault. Insufficient power, urea consumption too high or too low: The fault light remains on. Insufficient power, torque limited to 1800 rpm. The SCR system is not working properly, with urea consumption being too high or too low.

What Does the Steering Gear Assembly Include?

Directional steering gear assembly is designed to amplify the force from the steering wheel to the steering linkage and alter the direction of force transmission. Its primary functions encompass three aspects: 1. Amplifying the torque from the steering wheel: making it sufficient to overcome the steering resistance torque between the steering wheels and the road surface; 2. Reducing the rotational speed of the steering drive shaft: enabling the steering pitman arm shaft to rotate, driving the pitman arm to swing so that its end achieves the required displacement, or converting the rotation of the drive gear connected with the steering drive shaft into the linear motion of the rack and pinion to obtain the necessary displacement; 3. By selecting different thread spiral directions on the screw (worm), achieving coordination between the rotation direction of the steering wheel and the steering wheels.

How Many Copies of the Personal Vehicle Purchase Invoice Does the Owner Receive?

For the vehicle purchase invoice, the owner retains the sixth copy. A standard vehicle purchase invoice is a computer-generated six-part invoice.

Below is additional information: 1. Vehicle Purchase Invoice: The first copy, the invoice copy, serves as the payment receipt for the purchasing unit (usually retained by the 4S store) and is typically brown in color. The second copy is the tax deduction certificate for the purchasing unit and is green. The third copy, the tax payment copy, is retained by the vehicle purchase tax collection unit and is purple. The fourth copy, the registration copy, is kept by the vehicle registration unit and is blue. The fifth copy, the accounting copy, is the accounting voucher for the selling unit and is red. The sixth copy is the stub copy retained by the selling unit and is black. 2. Invoice Information: (1) Vehicle details, such as the VIN, engine number, and model information. (2) Purchaser information, including name and ID number. (3) Dealer information. (4) Purchase price, VAT, and the actual vehicle price excluding tax.

What Does Warning Protection System Malfunction Mean?

Warning alarm indicating a malfunction refers to a failure in the car's collision warning system that affects its normal operation. Possible causes of the malfunction include damage to the warning system's sensors, radar system failure, or issues with the warning control system. The warning protection system can take measures to protect occupants and road users. Additional notes: 1. During reverse driving, specific functions of the warning protection system are disabled. 2. If the electronic stability control system or airbag controller malfunctions, the warning protection system's functions cannot be used. 3. When the passenger airbag is deactivated, the seatbelt pretensioner on the passenger side is also disabled. 4. When driving outside public roads or when the vehicle is being transported on a car carrier, ship, or similar transport, please turn off the warning protection system. This prevents the warning protection system from intervening unexpectedly.

What are the road test items?

Here are the test contents for the Subject 3 road test: 1. Preparation before starting: Includes getting into the car, walking around the vehicle counterclockwise, fastening the seat belt, turning on the left turn signal, shifting into gear, releasing the brake, and honking the horn. 2. Test items: Starting, driving straight, shifting gears, changing lanes, pulling over, driving straight through intersections, turning left at intersections, turning right at intersections, crossing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, making U-turns, and driving at night. 3. Distance: The test distance for small vehicles should be no less than 3 kilometers, with no less than 20% of the candidates undergoing a night test. If a night test is not conducted, a simulated night light usage test should be performed.

What are the effects of changing from 265 to 285 tires?

There is no impact when changing from 265 to 285 tires. Here are some considerations for tire replacement: 1. Adjustment: The rim remains unchanged when switching from 265 to 285 tires, but certain adjustments to the vehicle's height and parameters are necessary. The effects of the change vary depending on the type of vehicle. 2. Error value: If changing from 245/40R20 tires to 265/40R20 tires, the difference in diameter between the old and new tires is 2.27%. It's important to note that the error value for tire replacement should be controlled within approximately ±3%.
