A high-pressure gas formed after the "liquid" (Freon) of the air-conditioning high-pressure pipe air-conditioning system flows and is vaporized (atomized). Different from household air conditioners, both heat and cold need to be obtained through the work of the compressor. The air conditioner of the car needs the compressor to work when it is designed to cool, and the hot air state can be provided by the engine part. During refrigeration, the high-temperature and high-pressure gas from the compressor is cooled by the unique internal structure of the condenser to form a liquid state, and then flows through the throttle valve to control the pressure and adjust the pressure before entering the evaporation box.

The brake system is mostly made of metal pipes. Because the metal has no elasticity, it will not expand at any time due to the increase of the pressure of the liquid, which can fully ensure the transmission of the braking force. The main features are: a "medium" that uses liquid (oil) pressure to transmit the braking energy of the hydraulic system, and plays the role of energy transmission, system lubrication, anti-corrosion, rust prevention, and cooling in the hydraulic system.

Car oil pipes and fuel tanks, if the car oil pipes are faulty, then remove the fault. When checking the oil pipe and the fuel tank, you can first disassemble the gasoline pump inlet pipe joint with a wrench tool, and then use suction to judge whether the oil pipe is blocked (but you must be careful not to suck the gasoline into the port), if there is oil sucked out, it means The fault is not the fuel pipe or the fuel tank of the car, but the gasoline pump; but if there is no gasoline sucked out, the failure of the car to ignite is likely to be a problem with the fuel tank and the fuel pipe of the automobile. This method is useful for further checking the leakage of the fuel pipe of the automobile. There is a certain reference effect.
