What Are the Causes of Idle Shaking After a Car Goes Through Water?

After a car goes through water, the engine may experience idle shaking due to a small amount of water entering the high-voltage wires, causing poor ignition system performance, or water entering the exhaust outlet. When a small amount of water enters the high-voltage wires, it can soak the air filter element, increasing intake resistance and allowing water to enter the combustion chamber. This leads to poor ignition system performance, and in severe cases, the spark plugs may fail to ignite, causing the engine to shake at idle or even stall. Water entering the exhaust outlet: Open the hood and remove the air filter to check if the filter is wet, as a wet filter can cause the engine to shake at idle. If the interior is dry, the car can be used safely. If the filter is wet, it should be replaced promptly, and the intake tract should be checked for water droplets or moisture. Precautions for driving through water: When driving through water, shift to 1st or 2nd gear in advance and maintain high throttle to pass through. If the water submerges the exhaust pipe, power will drop significantly. If accelerating doesn't help, maintain high throttle without shifting gears midway. After passing through, stop in neutral, then press the accelerator deeply several times to expel water from the exhaust pipe. Before driving again, press the brakes several times to ensure they are functioning properly.

Do Used Cars Still Require Purchase Tax?

Used cars do not require purchase tax. A vehicle only needs to pay purchase tax once, which is paid when the car is purchased as new. When trading a used car, the original owner must provide complete proof of purchase tax payment. However, if the purchase tax was not paid when the car was new, the new owner will need to make up the unpaid portion. The current vehicle purchase tax is a tax levied on units and individuals who purchase specified vehicles within China. It evolved from the vehicle purchase surcharge. The taxpayers of the vehicle purchase tax are units and individuals who purchase taxable vehicles, and the scope of taxation includes cars, motorcycles, electric vehicles, trailers, and agricultural transport vehicles, with a tax rate of ten percent.

What to Do When the Exhaust Pipe Sprays Water Excessively?

Excessive water spraying from the exhaust pipe is normal. Gasoline is a mixture primarily composed of hydrocarbon substances. After complete combustion, it produces some water vapor and carbon dioxide. Therefore, in winter, the white smoke emitted from the exhaust pipe is actually water vapor. When this water vapor passes through the cold exhaust pipe, it condenses into small water droplets, which then flow out of the exhaust pipe. With the use of ethanol-blended gasoline nowadays, even more water vapor is expelled. When the accumulated water reaches a certain level, you may see water spraying out from the exhaust pipe. In fact, this indicates that the engine is burning efficiently and operating normally.

Can different brands of urea be mixed?

Different brands can be mixed, but it is not advisable to do so for a long time. Definition of automotive urea: Automotive urea is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition is 32.5% high-purity urea and 67.5% deionized water. Reason for adding automotive urea: The main harmful substances in diesel vehicle exhaust are nitrogen oxides and particulate matter. While particulate emissions can be reduced through technical means inside the engine, the exhaust primarily contains nitrogen oxides. By injecting urea into the exhaust after-treatment device, the urea decomposes into ammonia at high temperatures, which reacts with nitrogen oxides in the presence of a catalyst to produce harmless nitrogen and water.
