What Causes the Mysterious Smell of Stinky Fish in the Car?

The reasons for the smell of stinky fish in the car are: 1. The air conditioning system malfunctions and produces odors; 2. Food in the car spoils and molds. The causes of odors inside the car are as follows: 1. Extensive use of plastic, rubber, and other materials in car interiors: Organic solvents, additives, and other components in these materials gradually release into the car environment during use. 2. Odors caused by the air filter: This odor is a sign that the air filter needs to be replaced. The air conditioning system has been decomposed by bacteria, leading to mold, and replacing the air filter can alleviate the odor. 3. Odors caused by the evaporator: This is due to mold inside the evaporator, requiring cleaning of the evaporator and air conditioning ducts.

Can I Take the Subject 1 Test with an Expired ID Card?

If your ID card has expired for the Subject 1 test, you can apply for a temporary ID card. The temporary ID card holds the same validity as the official one. Electronic ID cards cannot be used for the test. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," the Subject 1 test allows two attempts on the same day. If you fail the first attempt, you can take a free second attempt. If you fail the second attempt, the Subject 1 test is terminated, and you can only reschedule after ten days. The Subject 1 test consists of 100 questions, including single-choice and true/false questions, each worth 1 point, totaling 100 points. If you answer 11 questions incorrectly during the test, the system will automatically submit the test and end it. The Subject 1 test is computer-based and lasts 45 minutes. The content of the Subject 1 test includes: regulations on driving licenses and motor vehicle management; road traffic conditions and regulations; traffic safety violations and penalties; regulations on road traffic accident handling; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Notes for the Subject 1 test: Candidates should pay attention to their attire and avoid wearing slippers. Electronic devices and bags are not allowed in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen. Before entering the examination room, store personal belongings in a locker. In the examination room, the identity verification desk will assign a seat. Once seated, begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first attempt, you can retake the test the same day. If you fail again, you must pay to reschedule. After the test, queue to collect your score report and sign it. Failure to sign renders the test invalid. There is no limit to the number of times you can reschedule the Subject 1 test. Each subject allows one test attempt, with one retake if you fail. If you do not take the retake or fail it, the test is terminated, and you must reschedule. For Subject 2 and Subject 3, there are only five test attempts. Subject 2 and Subject 3 tests can be rescheduled after ten days. If you fail the Subject 3 safe driving knowledge test, your passing score for the road driving skills test remains valid. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the test on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the field driving skills test. Subject 3 is divided into two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, the official term (as per the Ministry of Public Security Order No. 123) does not include Subject 4.

Is Filing Required for Converting Manual Transmission to Automatic?

Manual transmission cannot be converted to automatic. Converting manual to automatic may involve illegal modifications, as illegal modifications include altering the vehicle's appearance, power system, transmission system, or braking system beyond the legal limits and manufacturer's approval, exceeding the original design load capacity and functions. Whether replacing the automatic transmission or installing an automatic clutch, both are modifications to the vehicle's power and transmission systems, and without approval from relevant authorities, they are considered illegal modifications. Here are the reasons: 1. Different control mechanisms: manual transmissions have a clutch, while automatic transmissions do not. 2. The principles and structures of the transmissions differ and are not interchangeable. 3. Car designs are matched systems; altering internal structures can affect safety. 4. The state prohibits unauthorized changes to a vehicle's internal structure.

What is the density of gasoline and water?

The density of water is approximately 1000kg/m^3, while the density of gasoline is about 800kg/m^3. The density of gasoline can vary due to seasonal factors. Here are some related details: 1. Density of different gasoline grades: The density of 92-octane gasoline is approximately 0.72g/ml, 95-octane gasoline is about 0.725g/ml, and 98-octane gasoline is around 0.737g/ml. 2. Reasons for different gasoline densities: Higher-octane gasoline has a greater density because gasoline is a mixture. Different grades are formulated by adding various additives to base gasoline. Higher-octane gasoline contains more additives, and since these additives have a higher density than base gasoline, the overall density increases with higher octane ratings.

Can I drive in the evening after drinking at noon?

You cannot drive in the evening after drinking at noon. Related information: 1. Reason: It is best to wait a full day before driving after drinking. If you still feel physically uncomfortable after drinking, it means the alcohol has not been completely metabolized, and there is a high probability of being considered drunk driving if you drive at this time. 2. Methods to speed up alcohol elimination: Drink plenty of water to increase urine output, thereby accelerating alcohol excretion. Avoid drinking strong tea, as it can further stimulate the body and increase the burden on the heart. If you consume strong tea after drinking, the acetaldehyde converted from alcohol may not have time to break down and will enter the kidneys with the tea, potentially causing kidney damage.
