Here is the analysis of the issue when the car air blower is not blowing air: 1. Clogged air filter: Normally, after cleaning or replacing the filter, the air flow from the air conditioner will return to normal. During inspection, you can remove the filter to see if the air volume increases. If it does, the filter is clogged; if there is no change, it indicates other issues. 2. Damaged blower motor: If the blower motor is damaged, it will result in insufficient air intake or no air intake at all, preventing the air from being blown out and causing the air conditioner to not blow air. You can make a preliminary judgment by setting the fan speed and air volume to the maximum and listening to the sound of the blower motor. If it does not rotate or rotates at a low speed, it indicates a malfunction, and the owner should take the car to a 4S shop or repair shop for maintenance.

Which is more durable between genuine leather and imitation leather for car seats?

Genuine leather car seats are more durable. Generally speaking, authentic leather seats can last the lifetime of the car because automotive leather differs from ordinary sofa leather. It undergoes multiple layers of processing techniques, such as high-temperature treatment. Even when exposed to temperatures above 200 degrees Celsius, it will only slightly shrink and deform, whereas sofa leather would instantly discolor and bubble. Compared to ordinary fabrics or cotton materials, leather is less prone to getting dirty. If left unused for a long time, it may only gather a bit of dust. Using a cleaning agent to wipe it can quickly remove stains, making the seats look as good as new. The natural enemies of genuine leather car seats are sharp objects and acidic or alkaline liquids.

How to apply for ETC?

ETC application steps: 1. Apply for a credit card; 2. Install and activate the device. Taking China Construction Bank as an example, first go to a CCB branch to fill out the credit card application form and prepare relevant documents such as ID card and vehicle license. If you already have a CCB credit card, you may still need to apply for a new one, otherwise you will have to pay for the device. After the credit card is approved, use it for two transactions, then take the transaction receipts to a CCB branch to receive the ETC on-board device for free. This device is usually installed on the windshield near the rearview mirror base. The entire installation and activation process is performed by professionals, and the device should not be removed arbitrarily afterward.

Does the Honda Crown Road have a particulate filter?

Honda Crown Road has a particulate filter. The particulate filter can reduce the particles in the engine exhaust emissions, recycle them, reduce vehicle exhaust emissions, increase the environmental protection of the vehicle, and reduce pollution to the atmosphere. Location of the particulate filter: The particulate filter is located behind the three-way catalytic converter and in front of the muffler, surrounded by the front and rear oxygen sensors. Methods to check if the vehicle has a particulate filter: Check the "Owner's Maintenance Manual" and the "Owner's User Manual" to see if there is a particulate filter function. Additionally, you can carefully check the fault codes in the manual to see if there is a "particulate filter" fault light indicator. Check the label on the oil cap. If the oil cap clearly states 0W-20 grade oil, it means the vehicle is equipped with a particulate filter. Check if there is a cylindrical section on the exhaust pipe behind the three-way catalytic converter. If there is, that is the particulate filter.

What is the difference between 92 and 95 gasoline?

The difference between 92 and 95 gasoline lies in the content of heptane and isooctane: 92 gasoline contains 92% isooctane and 8% heptane, while 95 gasoline contains 95% isooctane and 5% heptane. The gasoline grade represents the anti-knock performance, with a higher grade indicating stronger anti-knock ability. Different engines require different anti-knock values, so different grades of gasoline are suitable for different engines. Therefore, it is usually sufficient to use the gasoline recommended by the manufacturer. The type of gasoline a car uses is related to the matching of the engine system, essentially related to the engine's compression ratio. A higher compression ratio results in greater power and higher efficiency but lower stability, thus requiring gasoline with higher anti-knock properties.

When was 93 gasoline changed to 92 gasoline?

93 gasoline was changed to 92 gasoline in 2011. The following is relevant information: 1. Gasoline grade: It is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. It is not the case that the higher the grade, the better. The gasoline grade should be reasonably selected according to the engine compression ratio. 2. Additives contained: The additives in gasoline include anti-knock additives, active additives, catalytic combustion promoters, flame retardant regulators, and cleaning additives, etc. The proportions of these additives vary depending on the fuel grade. The main component of anti-knock additives is octane, and flame retardant regulators also have anti-knock functions. Therefore, a lower grade does not necessarily mean a lower anti-knock octane value, as the flame retardant regulators also play a role.

As for the vehicle registration certificate, similarly, there is no need to publish a loss notice or fill out a loss declaration. According to national laws, if a motor vehicle driver's license is lost, the driver should apply for a replacement at the vehicle management office where the license was originally issued or at any other vehicle management office. Below is relevant information about replacing a driver's license: 1. Required materials: The applicant's identity proof; a written statement of the loss of the motor vehicle driver's license; if applying through an agent, the agent's identity proof and the "Motor Vehicle Driver's License Application Form" signed by both the driver and the agent; two recent one-inch, bareheaded, white-background color photos. 2. Processing time: If all requirements are met, the driver's license will be reissued within one day.
