What Causes Loud Noise from Car Compressor?

The reasons for loud noise from car air conditioning compressor are as follows: 1. Air conditioning: Poor heat dissipation in the air conditioning system causes excessive load on the compressor. In this case, it is recommended to clean the dirt on the surface of the radiator and condenser. 2. Blockage: There is a blockage in the air conditioning system. Focus on checking the air conditioning expansion valve. If the expansion valve is blocked, it needs to be replaced. 3. Intrinsic issue: The problem lies with the air conditioning compressor itself. Excessive noise caused by worn pump head bearings requires replacement of a new air conditioning compressor. The car air conditioning compressor is the heart of the car air conditioning refrigeration system, responsible for compressing and delivering refrigerant vapor. Compressors are divided into two types: fixed displacement and variable displacement.

Most modern cars use an independent suspension system, which can be further divided into different structural forms such as the swing-arm type, trailing-arm type, multi-link type, candle type, and MacPherson suspension system. 2. Automobile Construction: Engine: The engine consists of 2 major mechanisms and 5 major systems, including the crank connecting rod mechanism, valve mechanism, fuel supply system, cooling system, lubrication system, ignition system, and starting system. Chassis: The chassis supports and installs the car engine and its various components and assemblies, forming the overall shape of the car. It receives the power from the engine to make the car move and ensures normal driving. Body: The body is installed on the frame of the chassis and is used for the driver and passengers to ride or load goods. The body of a car or passenger car is generally an integrated structure, while the body of a truck is generally composed of two parts: the cab and the cargo box.

Reasons for BMW 3 Series Remote Control Failure?

There are many reasons for remote key failure. One scenario is a dead battery or poor battery contact; The second scenario is the failure of the timing control module in the remote key, which can also render the remote inoperative; The third scenario involves factors like aging of the car's remote transmitter antenna, which can also cause such issues. If you encounter this situation, you can visit a repair shop for inspection and repair. Below is some extended knowledge about remote keys: 1. Working Principle: Simply put, the working principle is as follows: First, the key emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU, Electronic-Control-Unit) then identifies the signal code, and the system's actuator (motor or electromagnetic coil) executes the lock/unlock action. 2. Working Modes: According to their usage methods, they can be divided into three categories: active working mode, passive working mode, and coil induction mode.

What does REM mean in car subwoofers?

To be precise, it should be called the controller interface, which is the interface that controls the turning on and off of the subwoofer. More details about the REM in car subwoofers are as follows: 1. Introduction: REM is the interface that controls the turning on and off of the subwoofer; generally, the REM should be connected to the AMP or REM output of the player's main unit, which controls its turning on and off. If the main unit does not have this, it should be connected to the ACC. 2. Disadvantages: Although shorting it to a 12-volt interface can forcibly turn on the subwoofer, if it is a subwoofer for small cars, this connection method will continuously consume the battery's power. Over time, it may burn out the audio system and could also prevent the car from starting, so it is best to connect it to the main unit controller.
