It may be due to cylinder head deformation or aging of oil seals and gaskets. Engine Introduction: An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term engine can refer to both the power-generating device and the entire machine including the power unit (e.g., gasoline engines, aircraft engines). Oil Seal Introduction: Oil seal is the common name for general sealing elements, simply put, it seals lubricating oil. It is a mechanical component used to seal grease (oil being the most common liquid substance in transmission systems, also generally referring to liquid substances), isolating the components requiring lubrication in transmission parts from the output components to prevent oil leakage. Sealing elements for static seals and dynamic seals (generally reciprocating motion) are called oil seals. The representative form of oil seal is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely encased in rubber. The term oil seal commonly refers to this type of TC skeleton oil seal.

Do I Still Need to Carry My Physical Driver's License with an Electronic One?

The following situations still require carrying a physical driver's license: On-site traffic enforcement: If the penalty is less than 12 points and requires license confiscation, the person involved must bring the physical license to the traffic management department for processing; if the penalty reaches 12 points, the person must bring the physical license to a traffic management service point for full-score education. Non-on-site violation handling: Drivers can present an electronic license when dealing with non-on-site traffic violations, but for accumulated penalties of 12 points, general procedure processing, or cases requiring license suspension or revocation, the physical license must still be carried and handled according to current regulations. Driver's license procedures: For procedures requiring the return or endorsement of the original physical license, the person must submit the physical license. Traffic accident handling: If evidence collection requires license confiscation, the person must carry the physical license.

How Many Training Hours Are Required for Subject 3 Before Scheduling the Exam?

For the driving test Subject 3, a minimum of 24 training hours is required before you can schedule the exam. Each training hour lasts 60 minutes, with no single session being less than 45 minutes; otherwise, it will be considered invalid and not counted towards the training hours. Additionally, no more than 4 training hours are allowed per day. Here is some additional information: Exam requirements: Subject 1 requires 12 hours, Subject 2 requires 16 hours for C1 and 14 hours for C2, while Subject 3 and Subject 4 require 24 hours and 10 hours, respectively. If you fail Subject 2 or Subject 3, you must complete at least 10 additional training hours. Important notes: Subject 3 involves on-road driving, where road conditions can be complex with heavy traffic, intersections, crosswalks, school zones, and industrial areas. Always drive slowly and stay observant.

Are Shell Gas Stations Privately Owned?

Shell gas stations are privately owned, operating their retail business through more than 10 joint ventures and wholly-owned enterprises. In China, Shell has established cooperative relationships with CNPC, Sinopec, CNOOC, and Yanchang Petroleum. Currently, Shell owns over 1,500 gas stations in 21 provinces and municipalities across China, as well as in the Hong Kong and Macau Special Administrative Regions. Gas station precautions: 1. No smoking: Prohibiting open flames is a common warning seen everywhere at gas stations. For those who have the habit of smoking a cigarette while parked, this habit must not be brought to gas stations. This is because the concentration of gasoline in the unit space increases during refueling, and open flames could potentially ignite the gasoline. 2. Turn off the engine while refueling: Most car owners are aware that the engine should be turned off during refueling, and gas station staff will remind drivers to do so when they arrive. However, at some self-service or smaller gas stations, instances of refueling without turning off the engine have been observed.

Is It Harmful to Leave a Car Parked for 3 Months?

Yes, it can be harmful. If a car remains parked and unused for an extended period, the engine oil may oxidize and thin out, losing its lubricating effectiveness. Additionally, gasoline can evaporate due to insufficient sealing, preventing it from meeting the standard for normal combustion. Extended information: Forced starting: If the car is forcibly started, the lack of lubrication from the oil and the increased combustion temperature of the valves can directly cause the fuel pump to clog and the engine's intake and exhaust valves to break. Precautions: The car's engine should be started and driven at least once a month, allowing it to idle until the oil pressure light turns off. The vehicle should also be driven a certain distance to help re-coat the internal transmission components and rear drive shaft with oil and to wear in the clutch plates.

What is the normal range for tire pressure difference in kPa?

A difference within 10kPa is considered normal. However, exceeding 10kPa doesn't necessarily require adjustment, as variations in tire pressure monitoring system accuracy and vehicle load conditions can temporarily cause pressure differences. Standard tire pressure ranges are as follows: Standard tires: 2.4-2.5bar; Reinforced tires: 2.8-2.9bar; Maximum pressure: should not exceed 3.5bar. Related question: Is 2.0bar tire pressure normal? No. According to international GBT2978-2008 standards, the normal range for standard tires is 2.4-2.5bar. 2.0bar is below the minimum standard pressure, so it's abnormal. What's the normal tire pressure in winter? Winter tire pressure should follow the vehicle's standard pressure, typically increased by about 0.2bar. What's the normal tire pressure in summer? Generally, use the lower limit of the standard tire pressure. For example, 2.4bar for standard tires. If the vehicle is often parked outdoors, the pressure can be about 0.1bar lower than standard to prevent blowouts from high temperatures.

Can I Enjoy Warranty Service Without Maintenance at a 4S Shop?

During the warranty period, maintenance does not have to be done at a 4S shop. However, if the owner opts for maintenance at an external repair shop without authorization during the warranty period and issues arise, the manufacturer may refuse compensation. If the vehicle is still within the warranty period, it is advisable to have maintenance performed at a 4S shop. Below is additional information: Relevant regulations: The automobile three-guarantee policy stipulates that during the warranty period, consumers must have maintenance performed at a manufacturer-authorized 4S shop to enjoy the three-guarantee policy. Required materials: If maintenance was performed at a non-4S shop and you wish to enjoy the three-guarantee service, you will need to provide a series of relevant materials, including the repair shop's maintenance qualifications, material list, maintenance items, quality inspection sheet, duplicate of the completion and factory qualification certificate, purchase proof, etc., which can be quite cumbersome.
