How to Add Refrigerant Oil to Car Air Conditioning?

Does the car air conditioning consume the same amount of fuel regardless of the setting?

Car air conditioning does not consume the same amount of fuel at different settings, as detailed below: 1. Variable displacement compressor: If the car is equipped with a variable displacement compressor, when the temperature is set lower, the compressor needs to maintain a high displacement state for a longer time, resulting in higher fuel consumption. When the temperature is set higher, the compressor can reduce its displacement, decreasing the engine load and thus lowering fuel consumption. 2. Fixed displacement compressor: If the car has a fixed displacement compressor, it operates at full capacity initially, regardless of the air conditioning temperature setting. After running for a while, if the evaporator temperature is too low or the air conditioning pipeline pressure is too high, the compressor will stop working. When the air conditioning temperature is set too low, the fixed displacement compressor has to restart immediately, leading to increased fuel consumption.

Will placing a box in the passenger seat be photographed?

Detailed rules for deducting points due to placing a box in the passenger seat are as follows: 1. Judging by the size of the box placed in the passenger seat: According to relevant road traffic safety laws and regulations, placing a box in the passenger seat may or may not be photographed. It is important to note that as long as the box placed in the passenger seat is not large in size, does not obstruct the driver's view, and is not specifically for transporting goods, generally, even if photographed, no points will be deducted or fines imposed. 2. Deduction and fine details: However, if the box blocks the driver's view, or if it is placed in the passenger seat due to insufficient space for cargo, obstructing the driver's view, a warning or a fine of 20~200 yuan may be issued; if used for storing goods, a fine of 500~2000 yuan may be imposed.

What is the difference between internal and external tire pressure monitoring?

The differences between internal and external tire pressure monitoring are: 1. Price difference: Internal type is more expensive; External type is cheaper; 2. Installation time: Installing internal type takes more time and requires professionals to remove the tires; External type is simple to operate, car owners can manually replace it, which is simple and fast. The principle of internal and external tire pressure monitoring is the same, both use sensors on the wheels to detect and transmit signals via wireless transmitters to determine tire pressure. The so-called tire pressure refers to the air pressure inside the tire. When the tire pressure is too high, the vehicle's dynamic resistance is small and fuel consumption is low, but in emergency situations, sudden braking often fails to stop the car, or the braking distance is extended; When the tire pressure is too low, the vehicle's comfort is better, driving is quiet and smooth, but the rolling resistance is large and fuel consumption is high, and the vehicle is prone to standing waves and sudden tire bursts when driving at high speeds.

Do all cars have a left side lower than the right side?

There is a difference in height between the left and right sides, but it is not necessarily that the left side is lower than the right side. As long as the normal height difference between the left and right sides of a motor vehicle is within 40 millimeters, it is considered normal. Due to the specific characteristics of driving on domestic roads, where vehicles are required to drive on the right side, the left side of the vehicle may be slightly lower than the right side. Here is more related information: 1. Impact of the left side being lower than the right side: If the difference is within the normal range, there is no effect. If it exceeds the normal range, the vehicle needs to be inspected and repaired. The first components to check are the shock absorbers and the suspension system of the motor vehicle, or whether the tires are underinflated. 2. Motor vehicle shock absorption system: When parking, try to choose a relatively flat area. When passing over speed bumps, always slow down. The vehicle must be used strictly according to its rated load capacity and should not be used as a storage space. Regularly check the shock absorbers for any oil leakage issues.

What is the 0-100 km/h acceleration time of the Model 3?

The domestically produced version of the Model 3 has a 0-100 km/h acceleration time of 5.6 seconds, while the imported long-range version accelerates in 4.6 seconds, and the imported high-performance version achieves it in 3.4 seconds. The imported versions are all-wheel-drive models with dual motors, whereas the domestically produced version is a rear-wheel-drive model with a single motor. The Model 3 is a mid-sized pure electric vehicle from Tesla, a pure electric vehicle manufacturer based in Silicon Valley, USA. The domestically produced version features a rear-mounted motor, while the imported versions have one motor on the front axle and another on the rear axle. The domestically produced version's motor delivers a maximum power of 202 kW and a maximum torque of 375 Nm. This vehicle uses a ternary lithium battery. The imported long-range version's front motor has a maximum power of 147 kW, and the rear motor has a maximum power of 188 kW. The imported high-performance version's front motor has a maximum power of 147 kW, and the rear motor has a maximum power of 211 kW.
