Mini passenger vehicles: Vehicle length less than or equal to 3.5m, total engine cylinder displacement less than or equal to 1 liter. 5. Heavy-duty trucks: Vehicle length greater than or equal to 6m, total mass greater than or equal to 12,000kg. 6. Medium-duty trucks: Vehicle length greater than or equal to 6m, total mass greater than or equal to 4,500kg and less than 12,000kg. 7. Light-duty trucks: Vehicle length less than 6m, total mass less than 4,500kg. 8. Mini trucks: Vehicle length less than or equal to 3.5m, total mass less than or equal to 1,800kg. 9. Standard motorcycles: Maximum design speed greater than 50km/h or total engine cylinder displacement greater than 50ml. 10. Light motorcycles: Maximum design speed less than or equal to 50km/h, total engine cylinder displacement less than or equal to 50ml.

I usually drive to work, and the classification of motor vehicles is really not simple. I remember when I registered my first car years ago, the staff explained that as long as the vehicle is engine-powered, such as an internal combustion engine or electric motor, with a designed speed exceeding 20 kilometers per hour or a weight over half a ton, it must be classified as a motor vehicle. In China, it also depends on whether it meets the standards of the Road Traffic Safety Law, including maximum displacement, number of seats, etc. Non-motor vehicles like electric bicycles have looser standards. This affects whether you can drive on highways, whether you need a driver's license and compulsory traffic insurance, and safety standards must also be met, such as the braking system. It's best to check these details before buying a car to avoid problems later. I've seen people mistakenly drive unlicensed vehicles and get fined, which is quite troublesome. Now that electric vehicles are booming, the standards have become stricter, so I remind everyone to pay more attention to the environmental aspects.

Can Windshield Washer Fluid Be Replaced with Mineral Water?

Mineral water should not be directly used as a substitute for windshield washer fluid or washer concentrate. Ordinary mineral water contains many impurities that can accumulate in the rubber pipes over time, leading to clogged pipelines and affecting normal spray function. The details are as follows: 1. Hazards of Long-Term Use of Mineral Water: Prolonged use of tap water or mineral water may increase friction between the glass surface and the wiper blades, causing scratches on the glass. Moreover, plain water can only remove dust superficially and lacks the ability to thoroughly clean dirt or insect residues on the windshield. 2. Winter Precautions: During winter, it is essential to switch to winter-specific windshield washer fluid. Under no circumstances should mineral water or tap water be used as substitutes, as water freezes at 0°C. Frozen water not only prevents spraying but may also cause the windshield washer reservoir and pipelines to crack due to freezing.

What are the symptoms of non-atomizing fuel injectors?

Symptoms of non-atomizing fuel injectors include: 1. Poor engine combustion, causing shaking and easy carbon buildup; 2. Due to excessively large diesel droplets failing to burn completely, they flow along the cylinder wall into the oil pan, increasing the oil level, reducing viscosity, worsening lubrication, and potentially causing bearing seizure or cylinder scoring accidents. The cleaning method for fuel injectors is: 1. Open the engine hood and hang the cleaning device on the front hood of the car; 2. Remove and block the return pipe from the engine connection point; 3. Remove the fuel inlet pipe from the engine connection point and connect it to the cleaning device outlet pipe; 4. Open the fuel tank cap and remove the fuel pump fuse; 5. Add the cleaning agent to the storage bottle and adjust the pressure regulating valve knob to a smaller position; 6. Connect compressed air to the cleaning device air inlet and increase the pressure regulating valve pressure; 7. Open the cleaning device fuel inlet valve and start the engine.

What does the LIM button in a car mean?

The LIM button in a car stands for the speed limit function. Pressing this button when the vehicle is stationary will activate the speed limit function. Below are specific details about the speed limit function: 1. Overview of the speed limit function: The speed limit system was first introduced as a standard feature in European-spec F10 models. This system can limit the vehicle speed between 30-230 km/h. When the speed is below the set limit, the vehicle can operate normally. Similar to traditional cruise control systems, the speed limit system uses the engine control system and automatic transmission control system to regulate speed by reducing the torque output requested by the driver. 2. Exceeding the speed limit: If the speed exceeds the set limit, the system will issue a warning. When reaching or exceeding the set speed limit during downhill driving, the active braking mode will not be engaged. If a speed limit lower than the current speed is set during driving, the vehicle will coast until the speed drops below the set limit.

What are the disadvantages of hybrid cars?

Hybrid cars have the following disadvantages: 1. High cost: The new car price is expensive, resulting in high purchase costs, and the fuel savings are largely offset by the higher initial price; replacing the battery after it ages requires a significant expense, increasing the cost of ownership. 2. Higher failure rate: The dual-drive system increases the vehicle's failure rate, adding another ownership expense. 3. Low resale value: The resale value decreases over time because potential buyers must first consider the cost of battery replacement. Below is related information: 1. Power source: Hybrid electric vehicles use a traditional internal combustion engine (diesel or gasoline) and an electric motor as power sources. Some engines are modified to use alternative fuels such as compressed natural gas, propane, and ethanol. 2. Electric power system: The electric power system in hybrid vehicles includes highly efficient and reinforced electric motors, generators, and batteries. The batteries used include lead-acid, nickel-metal hydride, and lithium-ion batteries, with potential future use of hydrogen fuel cells.

Why Use Turbocharging?

Adding turbocharging to a car can effectively enhance the power of small-displacement vehicles without increasing the engine speed, while also boosting engine power. This avoids the high fuel consumption associated with large-displacement vehicles, offering outstanding economic benefits and mature technology. Additionally, it provides car manufacturers with considerable profits, as turbocharged vehicles are more expensive to maintain and service compared to naturally aspirated (non-turbocharged) vehicles. Below is an introduction to turbocharging: 1. Turbocharged engines have outstanding advantages, consuming less fuel and producing fewer tailpipe emissions than naturally aspirated engines of the same power output, which is crucial in today's environmentally conscious era. 2. Turbochargers operate at extremely high speeds and generate much higher pressure than mechanical superchargers. They utilize exhaust gases to drive a turbine in the exhaust pipe, which in turn spins a compressor in the intake pipe, achieving indirect pressurization without consuming engine power. 3. However, due to the inertia of the turbine and the significant resistance of the intermediate bearings, the turbine speed cannot increase immediately when exhaust gases suddenly surge, resulting in turbo lag.

Can the Vehicle Charge While Idling?

Vehicles can charge while idling, but the charging efficiency is not optimal. After the engine starts, the electricity generated by the alternator is primarily used to power the vehicle's own electrical systems, leaving little surplus current. The current only becomes sufficient when the engine speed exceeds 2000 RPM, so idling charging is not recommended. Below are specific details: 1. Modern vehicles use alternators for charging. The battery's power is mainly used to start the vehicle, which consumes a significant amount of energy. However, once the engine is running, the battery is no longer drained. 2. The power consumed during startup is replenished through the vehicle's charging circuit. Charging can occur while idling, but the charging current is relatively small. 3. Typically, household car batteries have a capacity between 54-60Ah. Battery capacity indicates the amount of power the battery can discharge under specific conditions (discharge rate, temperature, cutoff voltage, etc.). 4. The capacity of car batteries is usually measured in Ah. For example, a 60Ah battery can continuously discharge at 1A for 60 hours.
