What are the reasons for refrigerant leakage in car air conditioning?

Why Doesn't the Car Move When in Gear?

Reasons for an automatic transmission not moving when in gear include: leakage in the automatic transmission oil pan; loosened linkage or cable between the control lever and the manual valve rocker arm, keeping the manual valve in neutral or park position; clogged oil pump intake filter screen; severe leakage in the main oil circuit; or damage to the oil pump. Fault diagnosis and solutions: If a large amount of hydraulic oil sprays out from the pressure test hole, it indicates normal main oil circuit pressure, and the fault lies in the input shaft, planetary gear set, or output shaft of the automatic transmission, which should be disassembled for inspection. Check the linkage or cable between the automatic transmission control lever and the manual valve rocker arm for looseness. If loose, it should be reinstalled and the control lever position readjusted. If only a small amount of hydraulic oil flows out from the main oil circuit pressure test hole, with low or almost no oil pressure, open the oil pan to check if the oil pump intake filter screen is clogged. If not clogged, it indicates damage to the oil pump or severe leakage in the main oil circuit, requiring disassembly and inspection of the automatic transmission. Remove the plug from the main oil circuit pressure test hole, start the engine, shift the control lever to drive or reverse, and check for hydraulic oil flow from the test hole. If there is some oil pressure during a cold start but a significant drop when the engine is warm, it indicates excessive wear of the oil pump, which should be replaced.

How to Quickly Separate Water from Diesel?

Here are the methods for quickly separating water from diesel: 1. Sedimentation Separation Method: Under normal temperature and pressure, the density of diesel is lower than that of water. You can let the mixed solution stand still. After sedimentation, water will settle at the bottom of the container. Slowly tilt the container and pour out the diesel floating on top to separate the diesel from the water. 2. Heating Separation Method: Place the container over a flame. The principle is that the boiling point of water is much lower than that of diesel. After heating, water evaporates before diesel. When oil vapor starts to appear, it indicates that the water has completely evaporated, leaving only diesel.

Choose a clean parking spot: Select a clean parking location and avoid parking the vehicle in areas prone to mice, such as near cafeterias, hotels, or garbage dumps. 2. Regularly inspect and clean the car: Do not leave food or biscuits inside the car, and promptly dispose of edible waste. Clean the engine regularly to maintain a clean environment. 3. Regular maintenance: Check if the external air conditioning inlet and outlet filter screens are loose or damaged. Ensure the car is serviced on time, and during maintenance, request the staff to thoroughly inspect and test the engine.

Where to Connect the Reverse Detection Line?

Connect it to the wiring harness from the reverse light switch. Below is the relevant introduction about the reverse detection line: 1. Wired and Wireless: Wired systems require connecting the camera video from the rear of the vehicle to the navigation device, while wireless systems involve installing a wireless video transmitter behind the reverse camera and a wireless video receiver on the navigation device. 2. With and Without Video Interface: Only navigation devices with video input interfaces and functions can be equipped with wired or wireless reverse cameras. Some navigation devices on the market are labeled with video input interfaces but actually lack video input functionality, making them unable to support wired or wireless reverse cameras.

How Long Does It Take to Produce a Car?

It takes approximately 5 minutes to produce a car. Here are the specific details about car production: 1. Man-hours: In the entire industrial system (including the automotive industry), man-hours are used as a time unit to calculate the labor input of workers, with each hour worked by a worker counted as one man-hour. Based on the time it takes for a car to roll off the production line, producing a car takes about 5 minutes. 2. Research and Development (R&D) Design: Starting from the R&D and design phase of the vehicle model, depending on the automaker's capabilities and the positioning of the model being developed, designing and producing a car typically takes about 3-5 years.
