How to Distinguish Between China 5 and China 6 Emission Standards When Buying a Car?

The China 5 emission standard is marked with a "V", while the China 6 emission standard is marked with a "Ⅵ", both using Roman numerals. When purchasing a new car, the salesperson will provide a vehicle acceptance form, which includes details such as the model, color, emission standard, engine number, and chassis number. For used cars, you can check the vehicle's full model number on the environmental protection website. Below is an introduction to China 5 and China 6: 1. China 5 (Ⅴ) Emission Standard: "Limits and Measurement Methods for Emissions from Light-duty Vehicles" was announced by the Ministry of Environmental Protection on September 17, 2013. Starting from January 1, 2018, all motor vehicles nationwide fully implemented the China 5 emission standard. 2. The China 6a phase emission standard is essentially the same as "China 5", only adopting the strictest values from the "China 5" emission requirements. Compared to China 5, the China 6 standard reduces nitrogen oxides by 77%, particulate matter by 67%, introduces a limit requirement for particle number (PN), and tightens the durability requirements for emission control devices and the related requirements for On-Board Diagnostics (OBD).

Is Lower RPM Always More Fuel-Efficient When Driving?

Driving at lower RPM does not necessarily mean better fuel efficiency. This issue cannot be concluded simply. Firstly, when coasting in gear with an electronic fuel injection engine, the fuel supply is automatically cut off (zero fuel consumption) when the RPM exceeds a preset value, which varies among different engines, typically between 1200~1500 RPM. Therefore, coasting in gear without pressing the accelerator consumes no fuel when RPM is above 1500, while it actually consumes more fuel when below 1500 RPM. More details are as follows: 1. For manual transmission vehicles driving normally on highways, national roads, provincial roads, or urban elevated roads without traffic congestion, most of the time the highest gear is used with RPM exceeding 1500. In this case, releasing the accelerator without pressing the clutch and coasting in gear results in no fuel injection (zero fuel consumption). However, if coasting in neutral, although the engine RPM is lower, the engine must maintain idle fuel consumption to prevent stalling. 2. However, due to the engine braking effect when coasting in gear, the vehicle speed decreases faster compared to coasting in neutral, resulting in a shorter coasting distance. Considering that after the speed drops, you need to accelerate again to reach the original speed, the actual fuel consumption difference between these two driving methods is minimal.

Can a Car Under Loan Be Sold?

A car under loan cannot be sold. During the loan repayment period, the borrower does not have ownership of the vehicle but only the right to use it, making it impossible to complete the transfer of ownership. However, it is still possible to sell a mortgaged car through a debt transfer. Below are the legal methods to sell a car under loan: 1. Seller pays the remaining balance: First, contact the seller and negotiate for them to pay off the remaining loan. Then, retrieve the vehicle registration certificate, vehicle qualification certificate, and purchase contract from the bank, and proceed to the vehicle management office for the transfer. This method protects the legal rights of both parties, but finding a buyer willing to do this is rare, and the selling price is usually higher than other methods. 2. Transfer of mortgage agreement: (1) Both the buyer and seller must go to the bank to process the transfer of mortgage agreement. This requires providing a valid ID card (original and copy), the vehicle mortgage contract, and the vehicle license, followed by fingerprinting and signing. (2) The vehicle's source must be legal, and its information can be verified at a 4S shop or through the traffic police vehicle system. (3) The new owner can then use the vehicle license to purchase insurance from an insurance provider. (4) The price of a mortgaged car is generally very low, so careful consideration is advised before proceeding with the sale.

What to Do When the Oil Dipstick Smells Like Gasoline?

It should be repaired as soon as possible. The reasons for the gasoline smell in the oil are as follows: 1. The lubricating oil has not been replaced for a long time, resulting in a decrease in the oil film thickness and insufficient piston lubrication. 2. There is damage on the cylinder wall, leading to gas blow-by. 3. The engine has been used continuously for too long, causing the clearance between the piston and cylinder wall to increase. 4. Frequent short-distance driving without warming up the engine, resulting in insufficient time for gasoline to evaporate. Detailed analysis of why the oil smells like gasoline: 1. Long-term failure to replace the lubricating oil leads to a decrease in the oil film thickness and insufficient piston lubrication. Damage on the cylinder wall causes gas blow-by. 2. It may be due to frequent short-distance driving combined with a large amount of cold-start fuel injection, which can easily enter the oil. Additionally, if the car is stopped without sufficient warm-up, the gasoline inside does not have enough time to evaporate. 3. The engine has been used continuously for too long, causing the clearance between the piston and cylinder wall to increase. The only place where engine oil and gasoline come into contact is the combustion chamber. Due to uneven air-fuel mixture and excessive mixture concentration, the pressure in the combustion chamber is always greater than that in the crankcase, causing a small amount of the mixture to enter the crankcase.
