Should Refrigeration Oil Be Added from the Low Pressure or High Pressure Side?

Refrigeration oil should be added from the low-pressure side. A dedicated filling device injects it through the low-pressure line port. The functions of refrigeration oil are as follows: 1. Lubrication: Refrigeration oil lubricates the compressor during operation, reducing friction and wear, thereby extending the compressor's service life. 2. Sealing: It acts as a sealant in the compressor, ensuring tight seals between the piston and cylinder walls, as well as between rotating bearings, to prevent refrigerant leakage. 3. Cooling: While lubricating moving parts, refrigeration oil carries away heat generated during operation, maintaining lower temperatures for these components, thus improving compressor efficiency and operational reliability. 4. Energy Regulation: For refrigeration compressors equipped with energy regulation mechanisms, the oil pressure of refrigeration oil can serve as the driving force for the energy adjustment mechanism.

How to Judge the Distance Between the Right Side of the Car and Obstacles?

Methods to judge the distance between the right side of the car and obstacles: 1. Height: Mainly estimated based on the comparison of the blocked height. 2. Distance from the roadside: Determine the position of the roadside in the windshield (the left wheel is 10-15cm to the right from the left pillar of the windshield; the right wheel is 5-10cm to the left from the center line of the windshield); the distance from the roadside can be seen from the rearview mirror. 3. Right wheel position: Determine the position of the right wheel (middle of the front of the car or right wiper): relative to the ground at one-third of the right side of the front cover. 4. Three-point alignment: When the eyes, the front edge of the car hood, and the point where the obstacle touches the ground are aligned, the obstacle is approximately 1.5 to 2 meters away from the front of the car.

What does a sun exclamation mark on the dashboard mean?

On the dashboard, a sun exclamation mark is the brake pad warning light, indicating a brake pad fault, which serves as a reminder to replace the brake pads. When the front brake pads are nearing their wear limit, this warning will appear. It is recommended to check whether the brake pads need replacement. If the brake pads do not require replacement, adding some brake fluid may suffice. Before traveling, it is essential to inspect the braking system for normal operation, including the wear level of the brake pads. Additionally, ensure that the power steering fluid is sufficient. Special attention should be paid to the dust cover of the brake system's wheel cylinder. If this component is damaged and allows dust to enter, it can cause the piston to malfunction, leading to an increased braking distance when applying the brakes. If water enters this component, it can mix with the brake fluid, resulting in brake failure.

Where is the license plate 'Yi B' from?

Currently, there is no license plate with the prefix 'Yi B'. However, there is a license plate with the prefix 'Ji B', which belongs to Tangshan City, Hebei Province. 'Ji' is the abbreviation for Hebei Province. The license plate codes range from Ji A to Ji T, where Ji A is Shijiazhuang, Ji B is Tangshan, Ji C is Qinhuangdao, Ji D is Handan, Ji E is Xingtai, Ji F is Baoding, Ji G is Zhangjiakou, Ji H is Chengde, Ji J is Cangzhou, Ji O is for provincial government agencies, Ji R is Langfang, and Ji T is Hengshui. The first character of a license plate is a Chinese character representing the abbreviation of the province where the vehicle is registered. The second character is an English letter representing the code for the prefecture-level city where the vehicle is registered. The general rule is that 'A' represents the provincial capital, 'B' represents the second largest city in the province, 'C' represents the third largest city, and so on.

What is the difference between 98 and 95 octane gasoline?

Here are the specific differences between 95 octane and 98 octane gasoline: 1. Compression ratio: Vehicles with a compression ratio between 8.5-9.5 should generally use 95 octane gasoline; cars with a compression ratio greater than 9.5 should use 98 octane gasoline. 2. Octane rating: 95 octane gasoline has a lower octane rating than 98 octane gasoline. That is, 95 octane gasoline contains 95% isooctane, while 98 octane gasoline has an octane rating of 98%. The gasoline grade represents the octane rating of the gasoline. For example, 95 octane gasoline consists of approximately 95% isooctane and 5% n-heptane. Since isooctane has better anti-knock properties and n-heptane has poorer anti-knock properties, a higher grade indicates a higher octane rating, meaning the gasoline has better anti-knock performance.
