What to Do When the Exhaust Controller is Abnormal?

Exhaust controller abnormalities can be caused by the following reasons and solutions: 1. False fault: A fault code is reported, but the system works normally. This may be due to an operation that exceeded the computer's control range, resulting in a fault code feedback. The code can be cleared first, and then check if the fault code reappears. 2. Minor fault: The engine does not show any obvious issues, but further inspection based on computer detection reveals a minor fault that does not significantly affect normal driving. It should be identified and resolved promptly. Examples include faults in the intake pressure sensor, etc.

Does the Engine Oil Filter Need Frequent Replacement During the Break-in Period?

The general replacement interval is 10,000 kilometers. However, in China, the oil filter replacement is typically around 7,500 kilometers or may be reduced to about 5,000 kilometers due to road conditions and oil quality. Therefore, it is recommended to replace it at 5,000-6,000 kilometers for optimal performance. Below is relevant information about the oil filter: 1. Function of the Oil Filter: It filters out impurities, gums, and moisture from the engine oil, delivering clean oil to various lubrication points. To reduce friction resistance between moving parts in the engine and minimize component wear, oil is continuously supplied to the friction surfaces of moving parts, forming a lubricating oil film for lubrication. 2. Location of the Oil Filter: The coarse oil filter is installed after the oil pump and is connected in series with the main oil passage. It mainly includes metal scraper type, sawdust filter type, and microporous filter paper type, with the microporous filter paper type being the most commonly used today. The fine oil filter is installed after the oil pump and is connected in parallel with the main oil passage, mainly including microporous filter paper type and rotor type.

What Causes the Ticking Sound in a Car Engine?

Car engine ticking sound is caused by hydraulic lifter issues and excessive valve clearance in the engine cylinder head. This occurs because both the engine valves and hydraulic lifters experience certain wear over time. During cold starts, the oil pump hasn't fully built up oil pressure yet, leading to insufficient lubrication of components. Regular maintenance is essential for car engines: 1. Regularly change engine oil and oil filter: When oil passes through the fine pores of the filter, it traps solid particles and sludge. 2. Maintain good crankcase ventilation by servicing the PCV system regularly: Remove contaminants around the PCV valve as airborne pollutants can accumulate and potentially clog the valve. 3. Periodically clean the crankcase: Use BG105 cleaner regularly to maintain internal engine cleanliness.

Is it necessary to use full-coverage floor mats for a new car?

Whether it is necessary to use full-coverage floor mats for a new car can be decided by the owner based on their personal situation. Below are the advantages and disadvantages of full-coverage floor mats: 1. Advantages: Full-coverage floor mats provide an excellent user experience, covering almost the entire floor area. These mats consist of two layers—the first layer is a fixed mat, and the second layer is removable, making it easy to clean the car's interior by simply removing the second layer. 2. Disadvantages: After installation, the car's floor may experience reduced heat dissipation. Installation can be cumbersome, and when purchasing full-coverage floor mats, it is essential to select the correct brand and model compatible with the vehicle; otherwise, issues may arise during installation.

Is touch-up painting done for a small area or an entire panel?

Touch-up painting is done for a small area. If there is only minor scratching, repair shops generally fix the damaged area and its surroundings, which is known as touch-up painting. Below are the detailed explanations: 1. Touch-up painting: There are typically two methods for repairing car body paint—touch-up painting and full respray. If the damage is minor, repair shops usually opt for touch-up painting, which involves fixing the scratched area and its immediate surroundings. The advantages of this method are obvious: it's quick, simple, and material-saving. However, the drawbacks are also significant—it may affect the appearance, create color differences under sunlight, and result in uneven paint surfaces after repair. 2. Full respray: Except for the front and rear bumpers, which can be partially resprayed, the rest of the car panels require a full respray. If the scratches are not severe, polishing and waxing may suffice. However, if the primer is exposed or the scratches are deep, a full door respray is necessary. Partial resprays can lead to noticeable color mismatches, making it better to avoid them in such cases.

What is Vehicle Networking Technology?

Vehicle networking technology, also known as 'Automotive Mobile Internet of Things Technology', is introduced as follows: 1. Navigation function: With a button or a voice command, you can obtain desired information such as routes to your destination, road conditions ahead, and weather updates. 2. OBD function: In Chinese, it's called 'On-Board Diagnostics System'. By connecting to the car's OBD port, it can read vehicle data and store it in the cloud via wireless networks. Owners can then check the car's real-time status, such as fuel consumption, exhaust emissions, and fault codes, through mobile or computer clients.
