Currently, most China V vehicles in China achieve the China V emission standards through SCR technology (Selective Catalytic Reduction) in engine exhaust aftertreatment. The characteristic of this technology is that it must use automotive urea solution to reduce NOx in engine exhaust. Therefore, during operation, China V vehicles must not run out of automotive urea solution in the urea tank. The role of automotive urea solution: Adding automotive urea solution is not only beneficial for environmental protection, but also increases economic benefits in the long run, achieving a win-win goal for both the environment and vehicle owners. Precautions: If users do not add automotive urea solution or use inferior quality automotive urea, the engine's ECU will record the information of excessive vehicle emissions. During annual vehicle inspections, management authorities can read this information with specialized testing equipment and impose corresponding penalties according to regulations.

Is a new car scratch covered by 4S store warranty?

A new car scratch is not covered by the 4S store warranty, and the reason is: the scratch on a new car is a human factor and does not belong to the quality problem of the vehicle. The solutions for a scratched new car are: 1. Repair by sandpaper grinding. Clean and dry the scratched area of the car, and gently rub the scratched area with sandpaper dipped in water; 2. Repair with chilled cola. Pour a small amount of cola on a cloth and continuously wipe the scratched area; 3. Repair with essential balm. Pour a small amount of essential balm on a cloth and continuously wipe the scratched area; 4. Repair with toothpaste. Clean the scratch with a cloth, squeeze toothpaste onto a wet towel or soft sponge, and wipe the scratch up and down; 5. Repair with nail polish.

Where to Check Tire Pressure Monitoring on the Changan New Eado?

Changan Eado's tire pressure monitoring can be viewed on the central control screen. Changan Eado's direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. The system then transmits the pressure information from inside the tire to a central receiver module via a wireless transmitter, displaying the data for each tire's pressure. The system will automatically alert when the tire pressure is too low or if there is a leak. There are three commonly used methods of tire pressure monitoring: Direct Tire Pressure Monitoring: This system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, displaying the data for each tire's pressure. The system will automatically alert when the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between tires, the system monitors the tire pressure. Indirect tire pressure monitoring systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Introduction: This system combines the advantages of both the above systems. It equips direct sensors in two diagonally opposite tires and includes a four-wheel indirect system. Compared to using only direct systems, this hybrid system reduces costs and overcomes the limitation of indirect systems, which cannot detect multiple tires with low pressure simultaneously. However, it still cannot provide real-time pressure data for all four tires as effectively as direct systems.

What causes the fuel nozzle to shut off prematurely when refueling a Mondeo?

The nozzle shutting off prematurely during refueling can be caused by vapor generation, issues with the fuel gauge, or the nozzle being inserted too shallowly. It is recommended to first check if the fuel gauge of the Mondeo is damaged and to insert the nozzle as deeply as possible into the fuel tank opening to prevent fuel splashing out when the nozzle shuts off. Additionally, it's advisable not to fill the tank completely; refueling to about two-thirds of the tank capacity allows the vehicle to maintain optimal fuel conditions. Further details are as follows: 1. The fuel tank is divided into two sections: a main tank and a secondary tank. 2. Each section has its own fuel level sensor, and both sensors are connected in series. The fuel gauge displays the average of the remaining fuel in both sections. Poor contact at the main or secondary fuel level sensor contact points can lead to the aforementioned issue.

Where is the engine of Wuling Hongguang from?

The engine of Wuling Hongguang is equipped with the P-TEC1.2L engine, which is designed and manufactured according to the global powertrain standards of General Motors. The engine model used in Wuling Hongguang is PTEC1.2L, with a maximum horsepower of 107 HP, a maximum power of 52.2 KW, a maximum power speed of 5500 rpm, and a peak torque of 145 N.m. The engine of Wuling Hongguang can be maintained daily using the following methods: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected according to the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to the mechanical load, with the selection standard not lower than the requirements specified by the manufacturer; Regularly change the oil and filter. The quality of lubricating oil of any grade will change during use. After a certain mileage, the performance deteriorates, which will bring various problems to the engine. To avoid failures, the oil should be changed regularly according to the usage conditions, and the oil volume should be moderate; When the oil passes through the fine holes of the filter, the solid particles and sticky substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element will burst or the safety valve will open, allowing the oil to pass through the bypass valve, still bringing the dirt back to the lubrication part, accelerating engine wear and increasing internal pollution; Regularly clean the crankcase. During engine operation, high-pressure unburned gas, acid, moisture, sulfur, and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, mixing with metal powder generated by part wear to form sludge. When the amount is small, it is suspended in the oil; when the amount is large, it precipitates from the oil, blocking the filter and oil holes, making engine lubrication difficult and causing wear.; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale can not only ensure the normal operation of the engine but also extend the overall life of the radiator and the engine.
