What does DOT4 mean?

DOT4 is a type of brake fluid, typically ester-based. Below is an introduction to DOT4: 1. Composition: The ester type is based on the glycol ether type with the addition of a large amount of borate ester. Borate ester is formed through the esterification reaction of low-polyethylene glycol or propylene glycol with boric acid. Borate ester has a higher boiling point than low-polyethylene glycol or propylene glycol, resulting in better braking performance. Borate ester also has strong moisture resistance, as it can decompose the absorbed water, thereby slowing down the decrease in boiling point caused by water absorption. Therefore, the performance of the ester type is better than that of the glycol ether type, and its price is also higher. 2. Function: Since brake fluid is alcohol-based, it has strong hygroscopicity. Over time, the water content gradually increases. After about 12 months of use, the average water content in DOT4 brake fluid can reach 3%. When the brake fluid contains a higher amount of water, it can cause delayed braking and extended stopping distances. Therefore, it is recommended to replace the brake fluid every 2 years (or 40,000 kilometers).

How Often Should a Car Battery Be Charged?

If using an external charger, the battery should be charged once a month; for batteries not installed in a vehicle, charge at least once every two months; if the car is rarely used, it is recommended to charge the battery weekly. Methods for Charging a Car Battery: Charging with a charger is straightforward: open the car hood, take out the battery charger, connect the charging cables to the battery's positive and negative terminals, and adjust the charging current to begin charging. Note that the charging current should be one-tenth of the battery's capacity. For a standard 60Ah battery, charging typically takes about 8-10 hours. Daily Maintenance of Car Batteries: Car batteries require regular charging. If left unused for extended periods, they will gradually self-discharge and eventually become unusable. Therefore, it is advisable to start the car periodically to charge the battery. Avoid using car electronics after the engine is turned off, as this can damage the battery by drawing power without the engine generating electricity. Additionally, avoid parking the car in open parking areas for long durations. If long-term parking is necessary, remove the battery and take it with you.

Do I Need to File for Record When Changing Wheel Rims?

Modifying wheel rims does not require filing for record as long as the size remains the same as the original rims. However, if the size is altered, filing for record is necessary. Relevant information is as follows: 1. Penalty: If you change the rim size without filing for record at the vehicle management office, the vehicle will definitely fail the annual inspection, and it is also considered illegal. If caught by traffic police, you will be ordered to revert the changes and may face fines and penalty points. 2. Regulation: According to the motor vehicle registration regulations, any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, including replacing the frame, body, or engine, must be reported to the vehicle management office for modification registration.

What is the motorcycle license category?

Motorcycles require a license, not a Category C license, but rather Category D, E, or F. The details are as follows: 1. Category D: (1) Eligible vehicle type: Regular three-wheeled motorcycles. (2) Eligible vehicles: Three-wheeled motorcycles with an engine displacement greater than 50ml or a maximum design speed exceeding 50km/h. (3) Other eligible vehicle types: E, F. 2. Category E: (1) Eligible vehicle type: Regular two-wheeled motorcycles. (2) Eligible vehicles: Two-wheeled motorcycles with an engine displacement greater than 50ml or a maximum design speed exceeding 50km/h. (3) Other eligible vehicle types: F. 3. Category F: (1) Eligible vehicle type: Light motorcycles. (2) Eligible vehicles: Motorcycles with an engine displacement of 50ml or less and a maximum design speed of 50km/h or less.

What is the forward gear of an automatic transmission car?

Automatic transmission vehicles have forward gears such as D gear, L gear, and S gear. Among them, the most commonly used gear is D gear. Here is more relevant information: 1. Gear introduction: (1) P gear, the abbreviation of English parking, is the parking gear. After shifting into P gear, the vehicle's transmission will be locked. (2) R gear, the abbreviation of English Reverse, is the reverse gear. It is used when reversing; shifting into R gear allows the car to move backward. (3) N gear, the abbreviation of English neutral, is the neutral gear. 2. Main purpose: D gear is the most widely used forward gear in automatic transmission cars. Its main purpose is to enable the transmission to automatically select the appropriate gear in real-time through the computer and corresponding mechanical structure when the vehicle is moving forward, thereby eliminating the need for manual intervention in gear shifting, greatly freeing the driver's hands and feet, and improving driving convenience, ease, and comfort.

What Causes the Particulate Filter Blockage in the Sagitar?

GPF can capture particulate matter beyond the three-way catalytic converter, so after prolonged driving, a large amount of fine particulate matter accumulates on the GPF, eventually leading to blockage over time. Additionally, prolonged engine idling and stop-and-go city driving conditions can also cause GPF blockage. This is because the GPF operates at lower temperatures in these scenarios, preventing effective regeneration and creating a vicious cycle. Impact: When the GPF is blocked, it leads to poor exhaust flow, increased exhaust pressure, reduced vehicle power, and higher fuel consumption. Severe GPF blockage may even prevent the vehicle from starting normally. There are two types of particulate filters, with different handling methods for diesel and gasoline vehicles. Below are specific solutions for each type of particulate filter blockage: Diesel Vehicles: When the particulate filter in a diesel vehicle is blocked, park the vehicle and press the regeneration button on the central controller. The engine will automatically increase its speed, and after about ten minutes, the particulate filter will be cleaned. Gasoline Vehicles: For gasoline vehicles, shift to S mode and drive at higher speeds for a period to raise the exhaust pipe temperature. The particulate matter in the filter will then burn off, resolving the blockage issue.
