AdBlue is an exhaust fluid used in diesel engines, also known as automotive environmental urea. Below is related information: Origin of the name: The scientific name of automotive urea is Diesel Exhaust Fluid, commonly referred to in China as automotive urea, vehicle urea, or vehicle denitration agent. Automotive urea solution was first used in Europe under the name AdBlue, while in North America, it is called DEF (Diesel Exhaust Fluid). It is important to note that there are urea manufacturers abroad certified for AdBlue and DEF, with strict international standards, while very few domestic enterprises in China have obtained AdBlue and DEF certification. Composition: Automotive urea solution is a colorless, transparent, and clear liquid with a concentration between 31.8% and 33.2%, used for reducing NOx. Currently, the automotive urea solution in use is generally composed of 32.5% high-purity urea and 67.5% deionized water.

Reasons for Wuling Hongguang mini vehicle system failure?

Wuling Hongguang mini vehicle system failure may need to check whether there is cylinder scoring, excessive wear of valve seat rings, valve bending, and other issues causing severe cylinder leakage. Consequences: If the engine misfires for a long time, it may lead to afterburning, damaging the catalytic converter carrier, but it may not yet trigger the catalytic converter fault code. Catalytic converter blockage can also cause engine vibration. Vehicle infotainment module failure: Sometimes, due to the large number of electronic products in the infotainment system, the content displayed on the large screen is too much, which can cause interference between internal modules, leading to issues with the infotainment system. Repeated restarts may not help, and the only solution is to restore factory settings or visit a 4S store for a firmware update.

What is the maximum wading depth of the Audi Q3?

According to official information, the maximum wading depth of the Audi Q3 is 35 centimeters. Common tire specifications include 235/50R19 and 235/55R18, with a body height of 1616mm, a curb weight of 1570-1735kg, and it is a five-door, five-seat SUV. The maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, the maximum wading depth for sedans does not exceed 30 centimeters, while SUVs can handle slightly deeper water, though it is still advisable not to exceed 50 centimeters. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 centimeters, the Audi A4 has 32 centimeters, the Volkswagen Sagitar has 30 centimeters, the Land Rover Range Rover has 90 centimeters, the Jeep Compass has 48 centimeters, and the Toyota Highlander has 45 centimeters. SUVs clearly have a significantly higher wading depth compared to sedans. Generally, depending on the water depth and the vehicle's specifications, drivers should take different measures as follows: If the wading depth reaches the height of the exhaust pipe, it is still safe. Even if water enters the exhaust pipe, the pressure inside is sufficient to expel the water, as long as the engine is not turned off in the water, preventing water from flowing back into the vehicle. If the wading depth reaches the height of the door frame, it becomes more dangerous. The vehicle's circuits, electronic components, and sensors are mostly concentrated at the bottom, which could lead to short circuits, damaging critical electrical components and preventing the car from starting properly. If the wading depth reaches the height of the air intake pipe, it is extremely dangerous. Driving directly into such conditions can cause the engine to stall immediately, leading to permanent damage or rendering the engine unusable.

Based on the structure of the tire body, car tires can be divided into pneumatic tires and solid tires. Pneumatic tires are the most widely used. According to the tire pressure, pneumatic tires can be categorized into high-pressure tires, low-pressure tires, and ultra-low-pressure tires. 2. Most vehicles generally use low-pressure tires. Pneumatic tires can also be divided into tubed and tubeless types based on their structural composition. 3. Passenger cars commonly use tubeless tires. Depending on the arrangement of the internal cord layers and buffer layers, tires can be further classified into radial tires and bias tires.

Can R17 tires be replaced with R18?

Tire R17 cannot be replaced with R18. Here are the specific details about tires: 1. The R in R17 and R18 represents the diameter (in inches): R stands for the tire's diameter. R18 tires have a larger diameter, so they cannot be interchanged. 2. Tires are round, elastic rubber products mounted on various vehicles or machinery for ground rolling: Tires support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high/low temperatures during operation. Therefore, they must possess high load-bearing, traction, and cushioning performance.

How Many Feet Are Used to Drive an Automatic Car?

An automatic car is operated with one foot. Here are the specific details: 1. Whether it's a manual or automatic car, the right foot is used to control the accelerator and brake: During normal driving, the left foot rests on the floor in a standby position, while the right foot controls the accelerator. It is not recommended to use both feet to drive an automatic car. 2. Automatic cars cannot be towed: Automatic transmissions use hydraulic drive, which is different from the gear settings of manual transmissions. 3. Automatic cars may roll back when starting on a slope: The idle creeping force of an automatic transmission is limited. When the car is parked on a steep slope, the car's gravity often exceeds the creeping force at idle. In such cases, some cars may automatically increase fuel injection, while others may roll back.
