What is Automotive Urea?

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.

How Often Should the Throttle Body Be Replaced?

The throttle body does not have a fixed replacement interval or service life. It should be replaced whenever it becomes faulty. The throttle body is located at the engine's air intake. Its function is to regulate air entering the engine. After mixing with fuel in the intake manifold, this air forms a combustible mixture that ignites to generate power. Additional notes on throttle body maintenance: 1. Clean the throttle body regularly - excessive carbon buildup can cause engine power loss and increased fuel consumption. 2. Apply lubricant to the fixed metal retaining ring before disassembly to prevent thread stripping. 3. If the throttle opening remains unchanged after cleaning, excessive air intake may cause engine vibration during startup and weak acceleration.

What to Do If the ETC Device Won't Stick?

If your ETC device won't stick, you can visit the ETC service center or an ETC service outlet where you originally applied for it. Ask the staff for a new piece of 3M adhesive tape. Additionally, since the device has fallen off, the anti-tamper button on the back will have popped up, requiring you to reactivate the ETC. The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU. A red light will briefly turn on, and the OLED screen will display "Label Invalid, Please Insert Card," indicating the device is functioning properly. Clean the windshield to ensure the surface is smooth, clean, and dry. Then peel off the protective film on the OBU's adhesive backing and stick it to the installation location. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield, ensuring the chip is inserted into the OBU device. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Promotes low-carbon travel by allowing vehicles to pass through toll stations without stopping, reducing noise and exhaust emissions, and minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and stops, lowering wear and fuel consumption. Users also enjoy a 5% discount on toll fees; Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC systems more advanced, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

Why is the airbag light always on?

The reasons why the airbag light is always on are: 1. Foreign objects around the airbag sensor wiring harness causing false alarms of the warning light; 2. Error in the car ECU sensor data; 3. The vehicle has been parked in a humid environment for a long time or the wiring interface became damp during car washing; 4. Fault in the airbag itself; 5. Loose connectors. The airbag is an auxiliary protective device, made of special fabric nylon with a rubber lining, and filled with harmless helium when activated. Solutions for the airbag light being on include: 1. Check the connection of the connectors; 2. Inspect the contact condition of the grounding wire; 3. Take the vehicle to a 4S shop for computer diagnosis and troubleshooting; 4. Use an inspection tool to check the airbag system and read the fault codes.

Where is the water added in a car?

Car water is added to the car radiator, which consists of three parts: the inlet chamber, the outlet chamber, the main plate, and the radiator core. It is located on the right side of the engine compartment next to the windshield washer fluid filler port. The radiator cap has a warning sign to open carefully and beware of burns. The function of the car radiator is: the coolant flows inside the radiator core, and air passes outside the radiator core. The hot coolant dissipates heat to the air and cools down, while the cold air absorbs the heat dissipated by the coolant and warms up, thereby achieving heat exchange. The reasons for a car radiator lacking water are: 1. Water pipe joints or the pipes themselves leak; 2. The engine block has cracks, the cylinder head gasket is not tight or damaged, causing water leakage; 3. The oil cooler seal is damaged or has sand holes, leading to water leakage; 4. The radiator cap is not tight; 5. The heater radiator leaks; 6. The three-way pipe leaks.
