The reasons why the tire pressure warning light comes on and then goes off include a punctured tire, excessive tire pressure, prolonged driving with low tire pressure, and insufficient inflation leading to low tire pressure. The following are the hazards of both excessive and insufficient tire pressure: Hazards of low tire pressure: Insufficient pressure increases tire deformation, leading to cracks on the sidewalls and causing flexing movements. This results in excessive heat generation, accelerating rubber aging, fatigue of the cord ply, and breakage of the cords. It also increases the tire's contact area, accelerating wear on the tire shoulders. Hazards of high tire pressure: Excessive pressure overextends the tire cords, reducing the tire's elasticity and increasing the load on the vehicle while driving. This can lead to internal cracks and blowouts upon impact. Additionally, high pressure accelerates tread wear and reduces resistance to punctures.

Is the Location of Driver's License Important?

The driver's license is valid nationwide and has no impact. The new traffic law stipulates that driver's licenses can be renewed or replaced in other locations, and a motor vehicle driver's license can also be applied for in a temporary residence, but only a C1 or lower motor vehicle driver's license can be applied for. Article 13 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" is introduced as follows: 1. Introduction 1: For the first application for a motor vehicle driver's license, the permitted driving types can be urban buses, large trucks, small cars, small automatic transmission cars, low-speed trucks, three-wheeled cars, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, light motorcycles, wheeled self-propelled machinery, trolleybuses, and tramcars. 2. Introduction 2: For the first application for a motor vehicle driver's license in a temporary residence, the permitted driving types can be small cars, small automatic transmission cars, low-speed trucks, and three-wheeled cars. Legally obtained driver's licenses can be used nationwide, and driver's licenses from other places can also apply for license plates locally.

What to Do If Caught by Traffic Police for Expired Car Insurance?

If caught by traffic police for expired car insurance, the vehicle will be detained by the traffic management department of the public security authority. The vehicle owner or manager will be notified to purchase insurance as required and fined twice the amount of the minimum liability limit insurance premium that should be paid. More relevant information is as follows: 1. Article 98, Paragraph 1 of the "Road Traffic Safety Law" stipulates: In daily life, due to the negligence of the vehicle owner or manager, situations often occur where compulsory traffic insurance (i.e., compulsory third-party liability insurance for motor vehicles) is not paid on time. If caught by traffic police, the driver will be fined and receive 3 demerit points. 2. Vehicle Insurance: Also known as motor vehicle insurance or car insurance, it refers to a type of commercial insurance that covers liability for personal injury, death, or property damage caused by natural disasters or accidents involving motor vehicles. Vehicle insurance is a type of property insurance and is relatively new in the field of property insurance, as it emerged and developed alongside the appearance and widespread use of vehicles. 3. Unlike modern motor vehicle insurance: In the early stages of vehicle insurance, third-party liability insurance was the main coverage, gradually expanding to include risks such as collision damage to the vehicle body.

What Happens When Engine Coolant is Insufficient?

Insufficient coolant cannot effectively cool the engine. In mild cases, it accelerates engine wear, and in severe cases, it may cause engine burnout. Here is some relevant information about coolant: 1. Introduction: Automotive coolant, also known as antifreeze, is a chemically synthesized preparation primarily designed to prevent the engine's cooling system from freezing in low temperatures, with secondary functions including heat dissipation. 2. Function: The most important function of coolant is corrosion prevention. Corrosion is a chemical, electrochemical, and erosive process that gradually damages the metal surfaces within the cooling system. In severe cases, it can perforate the walls of the cooling system, leading to coolant leakage and potential engine damage.

What is the difference between four-stroke engine oil and automotive engine oil?

Here are the differences between four-stroke engine oil and automotive engine oil: 1. Structural aspect: In automotive engines, the engine is lubricated separately from the transmission and clutch, with the oil temperature in the crankcase ranging between 75-90°C; whereas in four-stroke engines, components such as the wet multi-plate clutch, high-speed and transmission gears, shift mechanism, as well as moving parts like pistons, cylinders, and intake/exhaust valves, are all housed within the same structure, sharing the same volume of oil. Moreover, the friction plates of the clutch and the rotation of transmission gears generate significant heat, causing the oil temperature in the crankcase to reach as high as 80-120°C. 2. Cooling effect aspect: The oil capacity of an automotive engine is approximately 5-7L, while that of a four-stroke engine is only about 1L. Oil must flow sufficiently to perform its cooling and other functions. The amount of oil significantly affects the cooling performance. Additionally, most four-stroke engines are generally air-cooled, which offers much poorer cooling efficiency compared to the radiator circulation cooling in automobiles. Even water-cooled engines have inferior heat dissipation due to their smaller water capacity compared to automobiles. This inevitably results in the oil temperature of four-stroke engines being significantly higher than that of automotive engine oil.

What are the symptoms of not changing engine oil for a long time?

Symptoms of not changing engine oil for a long time are as follows: 1. Reduced sealing effect: High-quality engine oil with appropriate viscosity can effectively seal the gap between the cylinder block and piston, preventing gas leakage. If the oil is not changed for a long time, it will become watery and lose its sealing function. 2. Reduced cooling effect: The heat absorption and conduction properties of oil are far superior to water. If the oil deteriorates severely, its cooling function will be greatly reduced. 3. Reduced lubrication effect: The viscosity of engine oil gives it strong adhesion, allowing it to form a protective film between gears, shafts, and other components, ensuring smooth operation and reducing wear. Deteriorated oil largely loses this function.
