Car air conditioning should normally have a high-pressure reading between 1.3 to 1.7MPa, and a low-pressure reading between 0.15 to 0.25MPa. The car air conditioning system is a device designed to cool, heat, ventilate, and purify the air inside the vehicle compartment. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. The presence of an air conditioning system has become one of the indicators of a car's comprehensive functionality. During summer, when there is a significant temperature difference between the inside and outside of the car, it is advisable not to immediately set the air conditioning to a very low temperature upon entering the vehicle. Instead, first use high airflow with natural ventilation to dissipate the hot air inside the compartment. Then, avoid closing all windows immediately; turn on the air conditioning and allow your body to gradually adjust before setting the air conditioning to the desired temperature and closing the windows. This approach prevents discomfort caused by a sudden drop in external temperature.

Is Adding Repair Fluid to Dry Batteries Actually Useful?

Adding repair fluid to dry batteries is not useful. Reasons why adding repair fluid is ineffective: Since maintenance-free batteries use lead-calcium alloy grids, they produce minimal water decomposition during charging and have low water evaporation rates. Additionally, their sealed casing design releases very little sulfuric acid gas. Compared to traditional batteries, maintenance-free batteries offer advantages such as no need to add any liquid, minimal corrosion on terminal posts and wires, strong resistance to overcharging, high starting current, and long charge retention. Dry Batteries: Dry batteries are actually called "maintenance-free batteries." Maintenance-free batteries feature a fully sealed structure and require no maintenance under normal usage, offering excellent performance characteristics such as high efficiency, long lifespan, no pollution, maintenance-free operation, and safety reliability. Due to their structural advantages, maintenance-free batteries consume very little electrolyte and generally have twice the lifespan of conventional batteries.

Can the antifreeze be filled to the maximum?

It is best not to fill the antifreeze to the maximum. During normal use, the amount added should preferably be between the marked scales on the reservoir. Methods to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze levels, although it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; add antifreeze promptly. Check the water level scale markings on the antifreeze reservoir. The antifreeze level should normally be between the maximum and minimum water levels. Whether the antifreeze is low depends on the scale. If the antifreeze is below the minimum level, it indicates a shortage. Method for replacing antifreeze: Before completely replacing the antifreeze, conduct a thorough inspection to check for any signs of leaks or cracks in the pipes, with a focus on the five-way hose. The five-way hose gets its name from having five connections to various parts. Antifreeze flows through the five-way hose and is distributed to different parts of the car to function. If there is any leakage of antifreeze in this section, replace the hose or re-secure the connections as needed. Drain the old antifreeze, then flush the fluid channels with clean water. Add clean water to the antifreeze reservoir, then continue filling the reservoir with water to allow it to flow continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water flowing out of the reservoir will have a faint pink color. Continue adding clean water until the water coming out is clear. Note: Do not forget to remove the heater hose and drain the water from the heater core.

What brand is the diesel engine of the BAIC BJ40?

The BAIC BJ40 is equipped with a 2.0T direct-injection turbocharged diesel engine from Yuchai, which is produced by BAIC itself. The engine model of the BAIC BJ40 is YC4Y20, with a maximum output power of 110 kW/4000 rpm and a maximum torque of 350 Nm/1800-2800 rpm. For daily maintenance of the BAIC BJ40 engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, select CB--CD grade diesel engine oil based on mechanical load, with the selection standard not lower than the manufacturer's requirements; Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication area, accelerating engine wear and internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What does the brand and model on the vehicle license mean?

The model on the motor vehicle license is the compiled information of the vehicle, and many important vehicle details can be obtained through the license. Registered model on the license: For domestically produced motor vehicles, the model registered on the license is compiled according to the vehicle product model coding rules, typically in the form of: "Product Brand" + "Product Model Name", such as "Changan-Alto SC7081C, Dongfeng EQ3100FE". For imported vehicles, the license may have a registration form similar to domestic vehicles, "Brand (in Chinese or English) + Model", but more commonly uses "Brand + VIN (part of the 17-digit VIN code)". Important notes: The vehicle license is the legal document permitting the motor vehicle to drive on roads within the country. The motor vehicle license in the driver's possession records many important details in detail, including the license plate number, owner's name, model category, engine number and chassis number, load capacity or passenger count, initial registration date, and annual inspection records, among others.
