In summer, if you need cool air, simply turn on the air conditioning switch, then press the A/C button, and rotate the temperature control to the blue position. If it's an automatic air conditioning system, just press the auto and A/C buttons to light them up. Below is an introduction to air conditioning cooling: 1. When the compressor is working, it sucks in low-temperature and low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the gaseous refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature and high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy into a liquid. 2. When the liquid refrigerant flows through the throttle device, its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature and low-pressure liquid refrigerant absorbs heat from the inside air passing through the evaporator, causing it to evaporate into a gas. The gas is then sucked into the compressor for the next cycle. In this way, through the circulation of the refrigerant within the system, the heat from the inside air is continuously absorbed and expelled to the outside air, gradually lowering the temperature inside the car.

When I usually drive and want to turn on the air conditioning for cooling, I just start the engine, press the AC button, then adjust the temperature knob to the lowest blue zone and increase the fan speed. It works easily in summer, but don't forget to turn on the recirculation mode so the cold air circulates inside the car faster for quicker cooling. Last time I tried and it didn't cool, I found out it was due to insufficient refrigerant, so regular checks of the air conditioning system are quite important, otherwise it might just blow hot air. Also, don't rush to turn on the AC right after starting the car; wait until the engine stabilizes to avoid overloading and damaging components. Simply put, it's just operating a few buttons while the engine is running, quite convenient without overthinking.

I always start the car first to ensure everything is working properly, then press the button with the snowflake or AC symbol on the dashboard to activate the cooling mode. Set the temperature to a lower level, such as around 16 degrees, and a medium fan speed is usually sufficient for cooling. Remember to turn on the recirculation mode, especially when the outside temperature is high, as it enhances the cooling effect. If you notice the air conditioning cooling down more slowly after prolonged use, it might be due to a dirty or clogged cabin air filter, which needs cleaning or replacement. It's also a good practice to turn off the AC a few minutes before parking and let the fan run to remove moisture and prevent moldy odors. The whole process takes just a minute or two—no need to complicate it.

I've tried it many times, turning on the car's air conditioning for cooling is quite simple: after starting the car, press the AC button to activate the compressor, set the temperature to the cool air range, and then adjust the fan speed as needed. Make sure the recirculation light is on, so the cold air circulates faster. If you encounter problems, first check if there's no fuel or a weak battery affecting the system's power supply, but in most cases, just pressing the buttons works without any special tricks. Occasionally, a small tip is to turn on the external circulation when parking to allow air flow and prevent odors.

What is the engine oil capacity for Honda CM300?

The engine oil capacity for Honda CM300 is approximately 1.5 liters. Motorcycle oil change intervals: New motorcycles require their first oil change at 300 kilometers (using the specialized oil provided by the dealer). The second oil change should be done at 600 kilometers, and the third at 1,000 kilometers. These first three maintenance sessions are crucial. After completing the initial three changes, perform maintenance every 500 kilometers thereafter. This practice helps prolong the motorcycle's service life. Conditions indicating the need for an oil change: When the viscosity of the engine oil undergoes significant changes under high temperatures—generally, if the 100°C kinematic viscosity deviates by more than 20%, replacement is necessary; or when the oil's detergency and dispersancy deteriorate, making it unable to dissolve and disperse carbon deposits generated during engine operation.

What Causes Engine Abnormal Noise When Driving Through Water?

The causes of engine abnormal noise when driving through water include water entering the brake pads, foreign objects trapped between the brake pads and calipers, water ingestion into the exhaust pipe, and foreign objects lodged in the chassis. Water entering the brake pads: If the vehicle drives through shallow water and water splashes onto the brake pads, abnormal noise during braking is normal. Simply dry the brake pads to resolve the issue. Foreign objects trapped between the brake pads and calipers: If the vehicle drives through shallow water, foreign objects such as plastic bags or mud may get trapped between the brake pads and calipers, causing abnormal noise during braking. Cleaning the foreign objects will solve the problem. Water ingestion into the exhaust pipe: If the vehicle drives through deep water, water may enter the engine through the exhaust pipe, preventing the fuel and air mixture from burning properly, resulting in abnormal noise. The vehicle should be moved out of the water, and the engine should be cleaned. Failure to do so may lead to engine failure or even complete engine damage. Foreign objects lodged in the chassis: If foreign objects become lodged in the chassis after driving through water, abnormal noise may occur while driving. Cleaning the chassis will resolve the issue.

Can Temporary License Plates Still Be Used After Receiving Permanent Plates?

After receiving permanent license plates, temporary plates can no longer be used. Once the official plates are issued, temporary plates become invalid regardless of whether they have expired or not. The first character of a license plate represents the abbreviation of the province where the vehicle is registered, the second is an English letter indicating the prefecture-level city code, followed by a five-digit serial number. The functions of license plates include: 1. Numbering and registering vehicle information; 2. Identifying the region to which the vehicle belongs; 3. Tracing the owner and registration details of the vehicle through the plate number. Types of license plates: 1. White represents military or police plates; 2. Blue represents ordinary small vehicles with fewer than 7 seats; 3. Yellow represents ordinary large vehicles; 4. Black represents foreign enterprise plates.
