What to Do About Car Battery Leakage?

Solutions for car battery leakage are as follows: 1. Visual Inspection: It is necessary to inspect the exterior of the battery to check if the casing is cracked. If there are small holes or overflow on the leaking surface, plastic welding can be used to patch them up. After patching, the concentration of the battery fluid can be measured with a hydrometer, and an appropriate amount of sulfuric acid and purified water can be added as needed. If it's due to evaporation, simply top it up with more fluid. 2. Internal Inspection: If the first step shows no issues, remove the panel and check for any signs of leakage around the safety valve. If there are none, proceed to the next step. If there are, the safety valve needs to be repaired or replaced. 3. Leakage Check: If the first two steps show no abnormalities, a pressure test is required. This involves pressurizing the battery with air underwater to check for bubbles. If bubbles appear, it indicates a leakage. If no bubbles are present, the battery is functioning normally.

How Often Should CVT Transmission Fluid Be Changed?

CVT transmission fluid generally needs to be changed every two years or every 40,000 kilometers. However, this may vary depending on the vehicle model, as different models have different requirements. The primary function of transmission fluid is to keep the shifting system clean and to lubricate the transmission components, thereby extending their lifespan. Below is more detailed information: 1. Due to differences in transmission design, transmissions are categorized into manual and automatic (which further includes CVT, AMT, etc.). Each transmission type has unique technical requirements. Even the same transmission model, when installed in different vehicles, may differ in torque, weight, speed, and structure. Therefore, manufacturers specify their own dedicated transmission fluids. 2. Automatic transmission fluid (ATF) is specifically designed for automatic transmissions. Early automatic transmissions did not use dedicated fluid but instead relied on engine oil. Due to significant differences in operating conditions and technical requirements, using engine oil as transmission fluid was quickly phased out. Modern automatic transmission fluid serves as both the hydraulic fluid for the torque converter and the lubricant for the planetary gear structure, as well as the hydraulic fluid for the shifting mechanism. Under normal driving conditions, ATF should be changed every 120,000 kilometers, while under severe driving conditions, it should be changed every 60,000 kilometers.

What are the reasons for feeling lack of power when stepping on the accelerator?

Specific reasons for feeling that the car lacks power and accelerates slowly when stepping on the accelerator are as follows: 1. Clutch slipping: The main cause of clutch slipping is insufficient friction on the clutch friction plate; shifting gears prematurely or disengaging before the clutch is fully engaged; driving for extended periods with the clutch partially engaged or coasting with the clutch depressed; shifting or disengaging gears improperly, and applying excessive throttle when the gear is not fully engaged or disengaged, leading to abnormal wear of the clutch plate. 2. Engine issues: The source of power is fuel combustion, and the engine is responsible for supplying fuel and converting chemical energy into mechanical energy. Therefore, when the car lacks power and accelerates slowly, the engine system should be a key focus for inspection. 3. Engine oil system: The importance of engine oil is self-evident—it ensures sufficient lubrication, reduces resonance, and enhances the smooth operation of the engine. If the engine oil is insufficient for a long time, mild cases may result in insufficient power and increased fuel consumption; severe cases may lead to piston knocking, causing mechanical damage to related components. Additionally, a faulty fuel pump or a clogged fuel filter can also reduce engine power. 4. Engine intake system: Besides fuel, the engine also requires air. If components like the air filter or throttle valve are clogged or malfunctioning, leading to insufficient air intake, the car may experience sluggish acceleration, lack of power, and a jerky sensation.

What Are the Advantages and Disadvantages of Automobiles?

Here is an introduction to the advantages and disadvantages brought by automobiles: 1. Advantages of automobiles: Cars are an indispensable means of transportation in modern life, and their development and application have greatly accelerated the pace of human life. They also drive the development of other industries. As the ultimate mechanical product, the production, manufacturing, and application of automobiles are closely linked with other design and production industries. Human demand for automobiles not only promotes the automotive industry but also drives the rapid development of other industries. 2. Disadvantages of automobiles: While consuming large amounts of resources, the exhaust emissions from automobiles can severely impact human health. Carbon monoxide in car exhaust combines with hemoglobin in the blood 250 times faster than oxygen. Therefore, even inhaling trace amounts of carbon monoxide can cause terrible hypoxic damage. Mild cases may experience dizziness and headaches, while severe cases can result in permanent damage to brain cells. Nitrogen oxides and hydrocarbons can cause irritation in susceptible individuals, leading to eye diseases and laryngitis. The benzo(a)pyrene in automobile exhaust is a carcinogenic substance, a highly dispersed particle that can remain suspended in the air for several days and nights. Once inhaled by humans, it cannot be expelled and accumulates to a critical concentration, potentially triggering the formation of malignant tumors.

What are the symptoms of oil emulsification?

If the engine oil emulsifies, some white milky substance will appear on the engine oil filler cap, which is a symptom of oil emulsification. Oil emulsification is caused by water entering the engine oil. If the oil emulsifies, it needs to be replaced immediately, otherwise it will cause engine damage. Here are the hazards of oil emulsification: 1. When emulsified oil leaks water in places like the bearings of mechanical equipment, it can likely destroy the oil film. 2. The emulsified liquid contains liquid water, which stays on the surface of mechanical parts and can cause rusting of equipment components, affecting the normal operation of the unit. 3. Emulsified oil deposits in the lubrication system, affecting the normal circulation of the lubricating oil, leading to insufficient oil supply to mechanical equipment and causing mechanical failures. 4. If emulsified oil is not treated promptly with equipment like oil purifiers, it will accelerate the overall aging of the oil. At the same time, the aged oil will produce harmful substances such as naphthenic acid soap and colloids, further accelerating the emulsification of healthy oil. 5. After the car engine oil is emulsified, the lubricating effect of the engine oil is greatly reduced, increasing the friction coefficient among various mechanical equipment components. During the operation of mechanical equipment, bearings are highly likely to be damaged due to overheating.

Can ETC Be Fraudulently Charged After Installation?

ETC devices are divided into three types of cards: prepaid cards, debit cards, and bank co-branded cards. The likelihood of fraudulent charges varies among these three types of cards. Here is a detailed analysis: 1. Prepaid Cards: These cards require users to top up before use and are not linked to bank cards. Users can only use them after depositing money into the card. Therefore, they do not have the quick payment or cash deduction features and cannot be recognized or fraudulently charged by POS devices. 2. Debit Cards: These products include corporate debit cards and bank debit cards. Corporate debit cards are electronic payment cards for highways issued by provincial network companies to corporate users, allowing one account to correspond to multiple cards and vehicles, enabling transfer top-ups, consolidated invoice printing, and reducing corporate vehicle management costs. Bank debit cards are electronic payment cards for highways jointly issued by provincial network companies and partner banks, linked to designated bank cards or accounts, usable without top-up. Debit cards carry the risk of being fraudulently charged by POS devices that support quick payment. 3. Bank Co-branded Cards: These cards allow spending before repayment and combine financial functions with highway electronic payment, usable without top-up, featuring dual-card integration. These ETC bank co-branded cards are essentially bank cards with quick payment functionality, as they have and enable the 'small amount contactless payment without password or signature' feature. Therefore, when such a card is inserted into an in-vehicle ETC device, it may be fraudulently charged if encountered by a POS device that supports quick payment.
