What are the consequences of excessive engine oil?

Excessive engine oil can lead to reduced vehicle power and oil leakage issues, cause oil burning, and result in clogging of the three-way catalytic converter. Reduced power and oil leakage issues: Too much oil increases internal oil pressure, causing poor operation of some engine components, which fails to provide sufficient power to the vehicle. Additionally, the increased oil pressure may damage seals, leading to oil leaks. Oil burning situation: When the engine oil exceeds the standard level, the crankshaft's rotation will churn the oil, producing a large number of bubbles. These bubbles are carried into the combustion chamber through the ventilation system and burned, resulting in oil burning. These bubbles can also cause wear on the cylinders and pistons. Three-way catalytic converter clogging: Burning engine oil produces certain residues that are not expelled from the vehicle but instead accumulate inside the three-way catalytic converter. Since this is not easily noticeable during normal operation, by the time it accumulates to a certain extent, the three-way catalytic converter may be beyond repair.

What documents are needed to apply for ETC for a car?

According to the "Implementation Plan for Accelerating the Application of Electronic Non-stop Toll Collection Services on Highways" issued by the Ministry of Transport, the following documents are required to apply for ETC: the vehicle owner's valid ID card, driver's license, and vehicle registration certificate. If the application is made by a proxy, the proxy's valid ID card must also be provided; the current year's vehicle insurance policy; for corporate applications, the handler's ID card (or driver's license), the company's organization code certificate (or business license), and the company seal are required. If applying for ETC through major bank branches, a debit or credit card from the corresponding bank must also be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the amount as a deposit when binding ETC with a debit card. ETC deduction principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane of the toll station, computer networking technology is used to settle accounts with the bank in the background, achieving the purpose of paying tolls without stopping at the toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs by reducing the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can increase vehicle passing efficiency by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also set a target in the main indicators of comprehensive transportation development during the "13th Five-Year Plan" to "achieve a 50% ETC usage rate for road passenger vehicles by 2020." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and increasing the ETC usage rate for passenger vehicles, efforts will be made to promote ETC usage for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a stopped vehicle ahead, to prevent the vehicle's ETC device from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters to avoid automatic sensing and paying for the vehicle ahead. The recognized speed for ETC lane passage is 20 km/h. Excessive speed will prevent the reading of vehicle device information and may result in failed fee deductions. Unauthorized disassembly or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will render the electronic tag invalid. It can be sent to the bank where the ETC card was issued or the highway service office for inspection. If the loosening or detachment is not due to human factors, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance may also cause fee deduction failures. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Excessive windshield thickness may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.

Should Car Windows Be Tinted?

Car windows do not need to be tinted. Here is some relevant knowledge about car window tinting: Functions of car window tinting: Heat and sun protection. Tinting film can effectively block a large amount of heat generated by infrared rays. UV protection. Medium and long waves of ultraviolet rays can penetrate thick glass, but applying heat-insulating film can block most UV rays, preventing skin damage and reducing the aging of car interiors. Safety and explosion-proof. The base layer of the film is made of polyester, which has strong tear and puncture resistance. Combined with the adhesive layer, the film enhances the strength of the glass, preventing injuries to passengers in case of accidental glass breakage. Disadvantages of car window tinting: Tinting the side and rear windows with dark film can significantly impair the driver's vision and field of view, especially during nighttime or in low-visibility conditions such as rain or fog. This becomes even more severe when turning or reversing, as the driver needs to observe the road conditions from the sides or rear. Severely obstructed vision directly affects the driver's ability to judge the surrounding environment during turns or reversing, greatly increasing the risk of traffic accidents and endangering the safety of passengers.

What are the types of diesel engine oil?

Lubricating oil viscosity classification for all-season oil grades includes: 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, etc. The following is an introduction to diesel engine oil: Diesel engine oil is the lubricating oil used in diesel engines. Diesel engine is the abbreviation for diesel-powered engine, which is characterized by high torque, high efficiency, and good economic performance. Its energy source comes from the combustion of diesel engine oil. Usage method: The maintenance of diesel engines using diesel engine oil is divided into three main parts. Carefully check whether the sealing gaskets of the air cleaner are installed incorrectly, wrongly, or missing, and ensure their tightness; maintain the lubricating oil filter to prevent the filter element from clogging, as negligence in this area can reduce the service life of the diesel engine; special attention should be paid to the fuel filter additive. Here, the fuel filter additive refers to the one in the fuel supply system. During routine maintenance, pay special attention to timely cleaning, promptly remove debris from various components, and ensure timely discharge.

Is the Quality the Same After an Engine Overhaul?

No, it depends on the extent of the engine damage. Generally, an engine overhaul refers to the wear of internal components, requiring the engine to be completely disassembled to inspect which parts need replacement, such as piston rings, pistons, bearings, cylinder boring, crankshaft grinding, etc. Additionally, related components must be removed and thoroughly cleaned, including the main engine block, radiator, oil circulation parts, etc., before being reassembled. Below are relevant details: Assembly Process: The assembly process significantly impacts the quality of an engine overhaul. Original factory engines are assembled using electric torque wrenches, with each bolt tightened to a specific torque standard, ensuring uniform engine performance. However, during an overhaul, mechanics often rely on experience rather than following the manufacturer's specifications, leading to inconsistent bolt torque, which greatly affects engine performance. Impossible to Restore Original Quality: It is impossible to restore the original factory quality after an overhaul. No matter how well the engine is repaired, it cannot match the original quality. First, the repair shop environment is not as clean as the factory's near-sterile conditions. Second, the factory meticulously calibrates the torque for every bolt and screw on the engine, a level of precision unattainable in a repair shop.
