Do the speed display screens on highways take photos?

The speed display screens on highways do not have the function of capturing speeding violations. Speed reminder screens: They are designed to provide speed feedback to drivers. In fact, the complete system of a speed reminder screen consists of a speed measurement screen (the core speed measurement and display component) and a speed limit sign. Each sign features a prominent number indicating the speed limit for that lane. When a detected vehicle exceeds this speed limit, the speed displayed on the LED screen turns red to alert the driver. Principle: The speed reminder screen is composed of a radar and an LED screen, operating on the principle of radar speed measurement. When a vehicle enters the radar detection zone, the radar continuously emits electromagnetic waves towards the moving vehicle, which are then reflected back. The speed of the detected vehicle is calculated based on the frequency difference between the emitted and reflected waves.

Is it safe to drive on the highway with a tire pressure of 2.9 bar?

It is not recommended to drive on the highway with a tire pressure of 2.9 bar. A tire pressure of 2.9 bar is already quite high, which can easily lead to tire blowouts and increased braking distances, posing significant dangers. Introduction to standard tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. The hazards of excessive tire pressure include: Reduced friction and adhesion of the tires, affecting braking performance; Increased steering wheel vibration and deviation, reducing driving comfort; Accelerated wear of the central tread pattern, shortening tire lifespan; Increased vehicle vibration, indirectly affecting the lifespan of other components. Additionally, it reduces the contact area between the tires and the road, diminishing the vehicle's handling and driving stability.

What is the approximate temperature for 60% oil heat?

During normal vehicle operation, the engine's standard working temperature for oil is approximately between 90~110 degrees Celsius. Therefore, 60% oil heat should be in the range of 70-90 degrees Celsius. Before reaching normal temperature: The engine's standard working temperature is around 90~110 degrees Celsius. Before reaching this temperature, the fuel supply system remains cold, making it difficult to fully vaporize gasoline efficiently. Under such conditions, combustion is less effective for engine startup. During this phase, the engine relies on the choke valve to restrict some air from entering the cylinders, increasing the fuel-air mixture ratio and raising the engine speed to prevent stalling. After reaching normal temperature: Once normal operating temperature is achieved, the automatic choke valve returns to its standard position through mechanical action. Hence, for vehicles that have been idle for extended periods, it is advisable not to drive within the first minute after startup. Instead, let the engine idle for about a minute to warm up.

What are the consequences of driving 20 kilometers without engine oil?

When a car continues to drive without engine oil, the lubrication effect becomes very poor. In severe cases, the lack of lubrication can cause the engine to seize. The less oil there is, the more severe the consequences will be. When the engine is started again, dry or semi-dry friction may occur between the cylinder and piston, accelerating the wear of parts and significantly increasing the resistance during startup, making it difficult to start. Functions of engine oil: Lubrication: The primary function of engine oil is to provide proper lubrication to the engine's pistons, bearings, and other components; Sealing: During the "power" stroke of the engine, it prevents high-temperature and high-pressure gases in the combustion chamber from leaking into the crankcase through the gap between the piston and cylinder. Symptoms of a car without engine oil: The oil light on the dashboard will illuminate. Therefore, when the oil light comes on, engine oil should be added immediately; Elevated water temperature and valve noise; There may also be knocking sounds in the engine.

What Are the Must-Know Tips for Passing the Subject One Exam?

The essential tips for passing the Subject One exam include overtaking taboos, right-of-way rules, and warning sign placement distances. Overtaking Taboos: Do not overtake ambulances, fire trucks, police cars on emergency duty, or engineering rescue vehicles; also avoid overtaking on pedestrian crossings, narrow roads, curves, narrow bridges, railway crossings, or tunnels. Right-of-Way Rules: Turning vehicles yield to straight-moving ones; right-turning vehicles yield to left-turning ones; downhill vehicles yield to uphill ones (unless the downhill vehicle is already halfway, then it proceeds first). All other vehicles must yield to buses, school buses, police cars, ambulances, or fire trucks. Warning Sign Placement Distances: 50-100 meters on regular roads; over 150 meters on highways.
