What are the hazards of electrolyte to the human body?

Electrolyte is a strong acid that poses certain hazards to human skin and eyes. In case of contact, it should be immediately rinsed with plenty of clean water, and severe cases should seek medical treatment promptly. The following describes the functions of automotive electrolyte: 1. Electrochemical reaction: When the battery discharges, the electrode plates absorb sulfuric acid from the electrolyte to release electrical energy. Without electrolyte, the battery cannot discharge electrical energy. When charging, the electrode plates release the sulfuric acid absorbed during discharge, restoring the plates to their initial state. 2. Conductivity: The positive and negative electrode plates of the battery are insulated from each other, and without electrolyte, an electric current circuit cannot be formed.

What to Do When Encountering a Yellow Light While Driving?

Yellow light flashing is a warning signal. At this time, you can either proceed through the intersection or wait. If the yellow light continues to flash, you may proceed as long as safety is ensured. Here are some relevant tips: 1. Avoid sudden acceleration: The correct approach is to reduce speed when approaching the intersection. When the yellow light comes on, apply the brakes and stop the vehicle as quickly as possible while ensuring safety. 2. Observe the distance of the vehicle behind before reaching the intersection: When passing through the intersection, be prepared to brake at any moment. Check the rearview mirror to ensure the following vehicle is at a safe distance. If the distance is too close, you can slow down by coasting and lightly tapping the brakes to signal the following vehicle to reduce speed, thus avoiding potential hazards. 3. Judge the braking distance: If the yellow light comes on when you are very close to the stop line and stopping completely is impossible, slow down as much as possible while passing through the intersection and try to bring the vehicle to a halt.

Where is the date on Goodyear tires?

Goodyear tire production dates can be found on the sidewall. When replacing tires, it's important to pay attention to the production date marked on the tire. Here is some information about Goodyear tires: 1. Introduction: Goodyear is the world's largest tire manufacturing company, headquartered in Akron, Ohio, USA. The company produces tires, engineered rubber products, and chemical products in over 90 factories across 28 countries. 2. Tire maintenance: Tires should be discontinued when worn down to the wear indicators. Wear indicators are generally located at a remaining tread depth of 1.6 millimeters in the tread grooves.

What items need to be replaced during a 20,000 km maintenance?

For a 20,000 km vehicle maintenance, it is necessary to replace the engine oil, oil filter, air filter, cabin air filter, and spark plugs. Below are the detailed explanations: 1. Replacement of engine oil and oil filter Reason: Replacing engine oil and oil filter is essential. Under the harsh conditions of high temperature and high pressure inside the engine, the shelf life of engine oil is significantly shortened, and its performance greatly declines. Over time, it fails to protect the engine effectively. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to the formation of sludge and clogging the oil passages. Engine oil and the oil filter should be replaced simultaneously. 2. Replacement of the air filter Reason: The air filter's function is to block dust and particles inhaled during the engine's intake process. If the filter is not cleaned for a long time, dust can enter the engine, causing abnormal wear on the cylinder walls. If it was not replaced during the 10,000 km maintenance, it must be replaced at the 20,000 km maintenance. 3. Replacement of spark plugs Reason: If the vehicle uses standard material spark plugs, preparations should be made to replace them at 20,000 km. Spark plugs directly affect the engine's acceleration performance and fuel consumption. If you feel the engine lacks power during driving, maintenance should be performed.

What to Do If You Accidentally Scratch Your Car

Here are the methods to deal with accidental car scratches: 1. Minor scratches on the body: If the car only has minor scratches and the marks are not deep, merely affecting the outermost layer of paint, then waxing can be used to repair the scratched paint. 2. Damage to the body's topcoat: If the topcoat has been damaged and part of it has peeled off, you can try to perform a DIY touch-up to repair it. 3. Scratches that have damaged the primer or even caused body panel deformation: The affected area's paint needs to be sanded off, followed by body panel repair, and finally, the application of multiple layers of paint.

How to Shift Gears Smoothly in a Manual Transmission Car?

Manual transmission cars require fully depressing the clutch pedal to shift gears. To become proficient, practice more. Here are the techniques for shifting gears in a manual transmission car: 1. Memorize the gearshift pattern: When seated in the driver's seat, the first thing you should do is glance at the gearshift diagram on the lever handle. Remember not to look down at the gearshift while driving, especially in urban areas or on highways, as this can cause the vehicle to veer off course and potentially lead to accidents. 2. Depress the clutch smoothly: Master the technique of depressing the clutch pedal smoothly. Develop a good habit of pressing it all the way down and releasing it slowly. 3. Master the timing of shifting gears: Shift gears when the engine speed is around 2000 RPM. First, reduce the throttle, then depress the clutch to prevent forced disengagement, and then shift gears. 4. Shift gears frequently while driving: Choose the appropriate gear based on the vehicle speed and road conditions. Infrequent shifting can cause the car to lug or the engine to rev excessively, increasing wear and fuel consumption. Therefore, it's essential to develop the habit of shifting gears frequently. 5. Make shifting movements smooth and continuous: Depress the clutch pedal all the way in one motion, and engage the gear in one smooth movement. Familiarize yourself with the gear positions and practice the feel. If the gear is not fully engaged, do not release the clutch pedal, as this can easily wear out the transmission gears.
