The China 5 emission standard is marked with "V", while the China 6 emission standard is marked with "Ⅵ", both using Roman numerals. When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes the model, color, emission standard, engine number, and chassis number. For used cars, you can check the emission standard by entering the vehicle's complete model number on the environmental protection website. The method to query the car's emission stage standard on the environmental protection website is as follows: 1. First, you need to know the complete model number of the vehicle you want to query, which is usually marked on the car's nameplate. 2. Visit the Motor Vehicle Environmental Protection Website, enter the condition (complete model number) in the input box on the webpage, input the correct verification code, and click "Query" to retrieve the relevant information of the vehicle, including the emission standard.

Is There Purchase Tax for Hybrid Vehicles?

Hybrid vehicles are exempt from purchase tax, according to the national regulations on new energy vehicles, which enjoy the policy of exemption from vehicle purchase tax. Here is the relevant information: The meaning of vehicle purchase tax: Vehicle purchase tax is a tax levied on units and individuals who purchase specified vehicles within the country, evolved from the vehicle purchase surcharge. The calculation method of purchase tax: Vehicle purchase tax is calculated based on the ad valorem rate method, and the formula is: Tax payable = Taxable price × Tax rate. If the consumer buys a domestic private car, the taxable price is the total price and additional fees paid to the dealer, excluding the value-added tax (VAT rate of 13%). Since the purchase price in the special invoice for motor vehicle sales includes VAT, the 13% VAT must be deducted first when calculating the vehicle purchase tax, i.e., the taxable price for vehicle purchase tax = Invoice price ÷ 1.13, and then the vehicle purchase tax is calculated at a rate of 10%.

How to Solve the Oil Burning Issue in Tiguan?

The solution to the oil burning issue in Tiguan: Timely maintenance should be conducted to prevent engine damage. The reasons for oil burning in Tiguan include the following: 1. Aging of valve oil seals. 2. Severe wear of piston rings, leading to excessive clearance between the piston and the cylinder wall. 3. Loose valve guides. These factors cause engine oil to enter the cylinder and participate in combustion. Below is a detailed introduction to the importance of lubricating oil for the engine: 1. The general requirements for an engine are small size, lightweight, compact structure, and high output power, which means its unit friction surface bears a significant load. 2. In addition to frictional heat, the engine is also affected by combustion heat, resulting in high temperatures on the friction surfaces, which reduces the viscosity of the lubricating oil and makes it difficult to form an oil film. 3. High-temperature and high-pressure combustion gases in the combustion chamber can leak into the crankcase through the gaps between the piston, piston rings, and cylinder liner. These combustion gases are the result of complete and incomplete combustion of fuel and a small amount of lubricating oil, producing gases and certain particulate matter (soot), which typically become the main components of crankcase blow-by. They can contaminate the lubricating oil and, under certain conditions, accelerate its oxidation.

What causes the hissing sound after the turbo reaches 2000 RPM?

This situation may be caused by a damaged wastegate in the turbocharger or an air leak in the intake pipe. It is important to promptly inspect and repair this issue to prevent further damage. Below is relevant information: Explanation of turbocharging technology: Turbocharging technology has been applied to automotive engines for a long time. It can increase engine air intake without raising engine displacement. Engine operation: A car engine uses a mixture of fuel and air as its energy source. By increasing the air intake and correspondingly increasing fuel injection, the amount of combustible mixture in the engine cylinders is effectively increased. With more fuel mixture in the cylinders, each combustion cycle releases more energy, thereby enhancing engine power. Components of a turbocharged engine: A turbocharged engine includes a turbocharger, which consists of two main parts - the compressor turbine and the exhaust turbine.

How to Align the Timing Belt on a Chery Tiggo 3?

The method for aligning the timing chain on a Chery Tiggo 3 is as follows: 1. Rotate the engine crankshaft to position the first cylinder piston at top dead center and secure it; 2. Align the timing mark on the camshaft gear with the timing mark on the chain and secure it; 3. Install the crankshaft drive sprocket and ensure the timing mark on the chain aligns with the mark on the sprocket; 4. Finally, ensure the three timing marks on the timing chain correspond with the two timing marks on the camshaft sprocket and the single timing mark on the crankshaft sprocket. If the car's timing is misaligned, minor issues may include early or delayed ignition, unstable idle, weak acceleration, engine shaking, and reduced power. Severe cases can lead to the engine failing to start, valves hitting the pistons, or even catastrophic damage such as piston failure, bent valve stems, or broken crankshafts. If the timing is significantly off, the vehicle may not start, or attempting to start it could cause severe interference between the pistons and valves, resulting in serious damage.

What are the manifestations of fuel pump pressure relief?

Fuel pump pressure relief can cause difficulties in ignition, engine shaking, reduced fuel supply, and negative pressure. The following are the symptoms of fuel pump pressure relief: Difficult ignition: The vehicle is hard to start. Shaking: The engine shakes. Reduced fuel supply: The manual fuel pump supplies less fuel. Negative pressure: Negative pressure appears in the fuel tank. Here are some extended details about the related content: Operation: When there is air in the diesel engine's fuel passage, such as when starting a new engine, the engine cannot start. The diesel fuel pump only works when the engine is started, and the manual fuel pump is used to pump fuel from the tank into the fuel passage. Usage: The manual fuel pump is suitable for transporting various oils, such as heavy oil, diesel, and lubricating oil. With copper gears, it can transport low internal point liquids. The various pump types of the manual fuel pump have a simple and compact structure, are easy to use and maintain, and have good self-priming properties. It is not necessary to fill the pump with liquid before each use.
