What Causes Slow Cooling of Car Air Conditioning After Prolonged Sun Exposure?

Car air conditioning cools slowly after prolonged sun exposure due to the compressor protection device tripping. Causes and solutions for excessively high pressure and overheating: 1. Excessive refrigerant: Appropriately reduce the refrigerant amount. 2. Poor heat dissipation: Check for dirt on condenser pipes and clean the condenser. 3. Blocked pipeline system: Refer to pressure gauge readings for diagnosis and resolution, then reprocess the system. 4. Dust accumulation on evaporator or filter: Reduced airflow causes system pressure and temperature imbalance; clean the evaporator or filter. 5. Possible refrigerant deficiency: When refrigerant is insufficient, compressor exhaust temperature becomes excessively hot, causing the overload protection switch to trip.

What is the cross-sectional area of car battery cables?

For small passenger vehicles, the national standard recommends pure copper cables with a cross-sectional area of 16 square millimeters. However, for large engineering vehicles, the recommended national standard is 25 square millimeters of pure copper. If the cable size falls below the recommended value, it may be difficult to jump-start the engine. With constant power and voltage, thicker cables have lower resistance, ultimately delivering greater current to the starter motor. Additional information: Precautions for using car batteries: Ensure the auxiliary battery is 12V and the negative terminal is properly grounded. Of course, all unnecessary lights and accessories should be turned off to prevent electrical accidents. Never reverse the polarity of the cables, as this may cause sparks during connection. Additionally, make sure the cables are tightly secured to both battery terminals (for full contact) to avoid sparking during the jump-start process.

What are the types of car accidents?

Car accidents are classified according to their consequences as follows: 1. Minor accidents: These refer to accidents that cause minor injuries to 1 or 2 people, or involve relatively small property damage. 2. General accidents: These refer to accidents that cause serious injuries to 1 or 2 people, or minor injuries to 3 or more people, or involve average property damage. 3. Major accidents: These refer to accidents that result in the death of 1 or 2 people, or serious injuries to 3 to 10 people, or involve significant property damage. 4. Catastrophic accidents: These refer to accidents that result in the death of 3 or more people, or serious injuries to 11 or more people, or the death of 1 person along with serious injuries to 8 or more people, or the death of 2 people along with serious injuries to 5 or more people, or involve extremely large property damage.

What are the three filters in the three-filter maintenance?

The three-filter maintenance refers to the maintenance of the engine oil filter, air filter, and fuel filter in a car. 1. Air filter: The function of the air filter is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles. 2. Fuel filter: The fuel filter's core is mostly made of filter paper, but some use nylon cloth or polymer materials. Its purpose is to filter out solid impurities such as iron oxide and dust, as well as water from the gasoline. This not only reduces the chance of the fuel injector being clogged by impurities but also ensures the quality of the gasoline flowing into the fuel system. 3. Engine oil filter: Its function is to remove various impurities from the engine oil to ensure the normal operation of the lubrication system.

What is the actual range of a Tesla in kilometers?

Tesla Model-S and Model-X Long Range versions achieved ranges of 660KM and 575KM respectively in the national standard driving cycle test. During actual road driving, the vehicle's range will continuously adjust based on usage conditions. The actual mileage is also influenced by other factors such as vehicle configuration, battery usage duration and condition, driving habits and operations, environmental and climate conditions, etc. Charging efficiency: With faster charging speeds and a new efficient powertrain design, Model-S and Model-X can now achieve up to 200kW charging power at third-generation Superchargers and up to 145kW at second-generation Superchargers. These updates can improve customer charging efficiency by 50%.

What is the speed limit for large buses on highways?

Highways generally have a speed limit of 120 km/h, so the speed of large buses is usually between 100-110 km/h. Lane speed limits: Highways should indicate the speed limits for each lane, with the maximum speed not exceeding 120 km/h and the minimum speed not lower than 60 km/h. Vehicle speed limits: On highways, the maximum speed for small passenger vehicles should not exceed 120 km/h, while other motor vehicles should not exceed 100 km/h, and motorcycles should not exceed 80 km/h. If the speed limit indicated by road signs differs from the above lane speed regulations, drivers should follow the speed limit indicated by the road signs.
