What Causes Oil Leakage from a Car's Chassis?

Oil leakage from a car's chassis is caused by the aging or damage of engine seals. Over time and with continuous thermal cycling, the seals gradually harden and lose their elasticity, and in severe cases, they may even break, leading to oil leakage. Engine oil seepage is not necessarily a malfunction. If oil seepage occurs, it should be carefully observed but there's no need to be overly sensitive—just keep an eye on it through regular checks. The chassis refers to the combination of the transmission system, running gear, steering system, and braking system in a car. It supports and installs the car's engine and its various components and assemblies, forming the overall structure of the vehicle. It bears the engine's power and ensures normal operation.

What kind of oil can be used as a substitute for gasoline?

The following fuels can be used as substitutes for gasoline: 1. Natural gas: As early as the 1860s, the French used engines fueled by coal gas. Natural gas has a high octane number, causes less air pollution, and ensures good engine startup in winter. By 1980, there were already 400,000 vehicles worldwide converted to use natural gas as a power fuel. However, using natural gas requires vehicle modifications, and the equipment at natural gas refueling stations is larger and more expensive than that at regular gas stations. 2. Hydrogen: Liquid hydrogen is an effective fuel. Experimental cars using hydrogen as fuel have already been developed. The drawbacks of liquid hydrogen are its low density and extremely low boiling point. 3. Alcohol: Many scientists believe that methanol and ethanol in alcohol are the most realistic competitors to gasoline. The challenge lies in the limited availability of raw materials for alcohol production. Japan is researching the use of seaweed as a raw material, Norway is studying the extraction of alcohol from coniferous wood, Mexico has successfully extracted alcohol from cacti, and New Zealand has achieved initial success in using orange peels to produce automotive fuel. It is estimated that 1 square meter of plants can produce 1 kilogram of fuel.

Can I Renew My Driver's License Without Going in Person?

You can renew your driver's license without going in person. Here are the precautions for license renewal: 1. The power of attorney application form requires the signatures of both the applicant and the agent: To authorize someone to renew your driver's license, the motor vehicle driver's license application form must be signed by both the applicant and the agent. The agent must also provide the original and a copy of their ID. If the agent is a non-local resident, they must additionally provide the original and a copy of their residence or temporary residence permit issued by the local public security authority. 2. No outstanding on-site traffic violations before renewal: Before renewing your driver's license, you must have no outstanding on-site traffic violations. If there are any, you must first handle them at the traffic management office where the violation occurred before you can renew your license. Electronic traffic violations or parking violations do not affect the renewal of your driver's license. 3. Renew your license three months before it expires: Generally, drivers should renew their licenses three months before they expire. Since the renewal process takes some time, if the new license has not been received by the time the old one expires, the old license will become invalid. In case of a traffic accident during this period, the insurance company will not provide compensation.
