Check the fuel system. If the air filter hasn't been replaced regularly, directly inspect whether the gas injector is clogged (possibly by engine oil or similar substances). The worst-case scenario would be severe valve wear. Here's some relevant information about vehicles running on gas: 1. Formation: Fossil fuels refer to petroleum or coal formed through billions of years of underground transformation of plants and animals. Natural gas is produced through petroleum cracking, representing a non-renewable energy source. 2. Considerations: The combustion products of natural gas differ from fuel ethanol. Fully combusted ethanol only produces carbon dioxide and water, and methanol is no exception. However, methanol is corrosive to metals, various alloys, and rubber products, which is why only problem-free ethanol is selected as the fuel for unleaded gasoline.

Will water in the rearview mirror affect the circuit?

No, it will not affect the circuit. Below is some related additional information: 1. Rearview mirror: It is a tool that allows the driver to directly obtain external information about the rear, side, and lower parts of the car while seated in the driver's seat. Rearview mirror adjustment can be divided into two types: external adjustment and internal adjustment. 2. External adjustment: This method involves manually adjusting the position of the mirror frame or mirror surface while the car is parked to achieve the desired viewing angle. This method is time-consuming and labor-intensive, making it difficult to complete conveniently in one go. The driver needs to reach out of the window to adjust it while seated, which is very inconvenient during driving or in rainy conditions. Generally, large vehicles, trucks, and low-end buses use external adjustment to reduce costs. 3. Internal adjustment: This method allows the driver to adjust the rearview mirror while driving, providing more convenient conditions for observing the rear view. Most mid-range and high-end cars use internal adjustment. This method is further divided into manual adjustment (cable-driven adjustment or handle adjustment) and electric adjustment.

What to Do If an Old Car Fails the Annual Inspection?

If an old car fails the annual inspection, cleaning the three-way catalytic converter and the front oxygen sensor can improve the pass rate. Here are the detailed explanations: 1. Cleaning the three-way catalytic converter: The three-way catalytic converter is crucial for exhaust purification and is prone to carbon buildup, clogging, poisoning, or failure. Carbon buildup and clogging are reversible and can be restored by cleaning, while poisoning, failure, or damage require replacement. Use an OBD scanner to check all sensors. If no faults are found in the electronic control system, the issue is likely with the three-way catalytic converter. For cleaning, consider using oxalic acid solution. Remove the three-way catalytic converter, fill it with oxalic acid solution, and let it sit for half an hour. 2. Cleaning the front oxygen sensor: The front oxygen sensor plays a significant role in exhaust emissions. The oxygen sensor is often a 'hotspot' for carbon buildup. Carbon deposits from incomplete combustion in the engine can accumulate on the surface of the oxygen sensor, leading to sensor failure over time.

Can You Drive for Three Days with a Spare Tire?

Generally, you should not drive for three days with a spare tire. Here is a brief introduction to spare tires: 1. Meaning: A spare tire is an extra tire prepared for a car. In case of a flat tire or other issues, the spare tire can promptly replace the damaged one, preventing the car from breaking down midway. 2. Types: (1) Full-size spare tire. A full-size spare tire has the exact same specifications as the other four tires on the car and can replace any temporarily or permanently unusable tire. (2) Compact spare tire. This type of spare tire has a slightly smaller diameter and width compared to the other four tires, making it suitable only for temporary use. It should only be installed on non-driven wheels, and the maximum speed should not exceed 80 km/h. (3) Run-flat tire. Also known as a safety tire (run-flat tire), commonly referred to as a "bulletproof tire," it is professionally translated as "tire that can run flat."
