What is the minimum speed limit on highways with a maximum speed of 120 km/h?

According to Article 78 of the "Regulations for the Implementation of the Road Traffic Safety Law", highways shall indicate the driving speed of lanes, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not less than 60 kilometers per hour. More extended information is as follows: 1. Overview: Highways, abbreviated as expressways, refer to roads specifically designed for high-speed vehicle travel. Highways have different regulations in different countries, regions, eras, and academic fields. According to China's "Technical Standards for Highway Engineering", highways are multi-lane roads exclusively for vehicles traveling in separate directions and lanes, with full access control. The average annual daily design traffic volume for highways should be more than 15,000 passenger cars, with a design speed of 80 to 120 kilometers per hour. 2. Others: Countries and regions around the world have their own construction standards for highways, without a unified model; there are differences in highway systems between different countries and regions. Some countries and regions include direct trunk roads with partial access control and non-full interchange sections as part of their highway systems.

Why are anti-sloshing baffles installed in tank-type hazardous chemical transport vehicles?

Tank-type hazardous chemical transport vehicles are equipped with anti-sloshing baffles primarily to reduce liquid fluctuations and impacts inside the tank, thereby improving the driving stability of the tanker. When the viscosity of the medium transported by the tanker is relatively low and the filling level is between 20% and 80%, anti-sloshing baffles must be installed inside the tank. The following introduces the details of anti-sloshing baffles: 1. Introduction to anti-sloshing baffles: The anti-sloshing baffle of a tanker, also known as a surge plate, is a crucial component in the design of liquid tank vehicles. Whether it's a fuel tanker, a water sprinkler, or a chemical liquid transport vehicle, anti-sloshing baffles are installed inside. 2. Standards: To achieve optimal anti-sloshing effects, it is generally recommended that the volume between two baffles should not exceed 7.5m³, or the spacing should not exceed 1750mm. The effective area of the anti-sloshing baffle should be greater than 40% of the tank's cross-sectional area, and the ventilation area in the upper part of the baffle should be less than 20% of the tank's cross-sectional area.

What Happens If You Leave the Car AC on All Night?

Leaving the car air conditioning on all night while the engine is running can cause damage to the vehicle. Below is relevant information about automotive air conditioning systems: 1. Introduction to Automotive AC: A car air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. It regulates the temperature and humidity inside the vehicle to provide a comfortable environment for the driver. 2. Working Principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the refrigerant's temperature and pressure increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy. The liquid refrigerant then flows through the throttle device, where its temperature and pressure decrease before entering the evaporator. In the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the cabin air passing through the evaporator and evaporates into gas. This gas is then drawn back into the compressor to begin the next cycle.

Is there any impact if replacing an 80Ah car battery with a 70Ah one?

Replacing an 80Ah car battery with a 70Ah one generally has no adverse effects on vehicle performance. Below are specific classifications of car batteries (also known as storage batteries): 1. Conventional Battery: The plates of conventional batteries are composed of lead and lead oxide, with the electrolyte being an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low cost; disadvantages include low specific energy (the amount of electrical energy stored per kilogram of battery), short service life, and frequent maintenance. 2. Dry-Charged Battery: Its full name is dry-charged lead-acid battery. Its main feature is that the negative plate has a high capacity for storing electricity. In a completely dry state, it can retain the stored charge for up to two years. When in use, you only need to add the electrolyte and wait for 20-30 minutes before it can be used. 3. Maintenance-Free Battery: Due to its structural advantages, maintenance-free batteries consume very little electrolyte and generally do not require the addition of distilled water during their service life. They also feature shock resistance, high-temperature resistance, compact size, and low self-discharge. Their service life is typically twice that of conventional batteries.

Can Car Shock Absorbers Be Adjusted to Be Softer?

Currently, car shock absorbers cannot be adjusted for softness or hardness. Here are specific methods to determine if the shock absorber springs are faulty: 1. Listen for sounds: When driving on rough roads, if you hear heavy impact noises from the car, and the more uneven the road, the more pronounced these sounds become, especially if they originate from the tire area, it indicates that the shock absorber may be faulty or no longer functioning properly. 2. Check for oil leaks: Observe whether there is any oil leakage. If the surface of the shock absorber is dry and clean, it is in normal condition. However, if you notice oil seeping from the top of the shock absorber, it suggests that the internal hydraulic oil may be leaking from the piston rod. Oil leakage indicates that the shock absorber is no longer functioning correctly and requires repair. 3. Observe the body's bounce: When the car is parked by the roadside, press down on one side of the car's tire with your body and quickly release. If the car bounces up and down with elasticity, the shock absorber is functioning normally. If the car only moves up and down without bouncing back after several repetitions, it means the shock absorber has failed.
