How to Calculate Vehicle Purchase Tax?

Vehicle purchase tax calculation formula: Purchase tax = Total vehicle price ÷ (1 + 13%) × 10%. Additional information: 1. Vehicle purchase tax: Vehicle purchase tax is a tax levied on units and individuals purchasing specified vehicles within China, which evolved from the vehicle purchase surcharge. The purchase tax is a tax collected by tax authorities on the acquisition of relevant properties and assets within the scope of the purchase tax system. 2. Calculation basis: The tax basis for vehicle purchase tax is calculated using the ad valorem rate method with tax-exclusive pricing, making the taxable vehicle's price (i.e., the tax calculation price) the basis for vehicle purchase tax. However, due to different sources of taxable vehicles, the composition of the tax calculation price varies, resulting in different structures for the vehicle purchase tax basis.

Why Does the Volvo S90 Engine Shake When Cold?

Volvo S90 engine shaking when cold can be attributed to the following reasons: 1. Low ignition energy at low engine temperatures. When the engine temperature is insufficient, both fuel and lubricant temperatures are low, requiring more fuel injection during cold starts to meet power demands. Larger spark plug gaps result in weaker ignition energy. Poor fuel atomization at low temperatures demands higher ignition energy. Over time, spark plug gaps tend to widen, reducing ignition energy and affecting engine performance, leading to shaking. Additionally, aging ignition coils, high-voltage wires, or electrical leaks can also decrease ignition energy. 2. Incorrect engine air-fuel mixture ratio. Improper fuel-air mixture occurs in both open-loop and closed-loop control systems. In closed-loop systems, oxygen sensors require a minimum operating temperature of 370°C. If the exhaust pipe temperature doesn't reach this level upon startup, the oxygen sensor remains inactive. This causes the ECU to miscalculate, leading to errors in fuel-air mixture and ignition timing control, reducing power output and causing shaking. 3. Carbon buildup on engine valves and intake ports. Carbon deposits can absorb fuel (similar to soil absorbing water from a riverbank), causing ECU miscalculations. For instance, if the ECU injects 100 units of fuel-air mixture but only 90 units reach the cylinder (with 10 absorbed by carbon deposits), even complete combustion of the remaining 90 units won't provide sufficient power, inevitably resulting in shaking. 4. Varying cylinder conditions. After prolonged use, clearance between cylinder liners and pistons becomes uneven—some larger, some smaller. During cold starts without proper oil lubrication, cylinders with larger clearances may leak high-temperature gases, reducing power output.

Do domestic cars have cavity wax injection?

Domestic car brands such as BYD, Volkswagen, and Chery utilize automotive cavity wax injection technology. Below is a detailed introduction about automotive cavity wax injection: 1. Overview: Cavity wax injection involves injecting a certain amount of liquid wax into the four cavities at the bottom of the car body. Through specific processing techniques, the wax remaining inside the car body cavities forms a uniform protective wax film, preventing water droplets from entering and ensuring excellent anti-corrosion performance for the entire vehicle. 2. Technology: When manufacturing components with cavities, injection holes are usually pre-designed. (After professional design, wax injection is typically performed directly through some threaded holes and weight reduction holes, without the need for dedicated wax injection holes.) Some enclosed areas may have holes opened to facilitate the outflow of liquid wax during the wax draining process in the wax draining room.

Are there restrictions for China IV vehicles in Beijing?

China IV vehicles are restricted in Beijing and require a Beijing Entry Permit. Below are detailed explanations about the China IV standard: 1. Overview: The China IV emission standard is the national fourth-stage motor vehicle pollutant emission standard. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. 2. Others: The China IV emission standard applies technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices to control and reduce vehicle emissions below specified limits.

How Long Does It Take for Subject 1 Appointment to Be Approved?

Generally, after making an online appointment for Subject 1, you will receive an SMS notification within one week. Below is relevant information about the Subject 1 exam: 1. Practice Questions: Current practice question software databases are nearly identical to the actual exam database, and the testing mode fully replicates the real exam. Simply practicing questions is sufficient. 2. Exam Format: Each examinee's questions are randomly selected from the database in proportion, totaling 100 questions with one point per question. A passing score is 90, and the exam duration is 45 minutes. 3. Retake: If you fail the first attempt during the Subject 1 exam, you can retake it immediately. If you fail again, the exam is considered completely failed, and you will need to make another appointment. 4. Validity Period: For subsequent appointments, there is no need to re-complete online study hours. You can directly apply through the online platform. After enrolling for a driver's license, you will receive a Learning to Drive Certificate, which is valid for three years. Within this period, you can make unlimited appointments for the Subject 1 exam.
