What are the causes of abnormal noise in a car's air conditioning pump?

Car air conditioning pump abnormal noise causes are: 1. The electromagnetic clutch is contaminated with sewage or mud, causing damage to the inner bearing and resulting in abnormal noise; 2. Loose drive belt increases the load on the electromagnetic clutch; 3. Repeated engagement of the electromagnetic clutch leads to insufficient power generation from the alternator; 4. Excessive gap between the electromagnetic clutch and the compressor; 5. Lack of lubricating oil inside the compressor. Functions of car air conditioning: 1. Drawing in fresh air from outside for ventilation and air exchange, preventing window fogging; 2. Removing dust, odors, smoke, and toxic gases from the car's interior air, making the air inside the car fresh, and humidifying the car's interior air to increase relative humidity.

Can the XRV start without the key after unlocking?

The Honda XRV can still start without the key after unlocking, thanks to its keyless entry system. Here are the relevant details: 1. Keyless Entry: Keyless entry, abbreviated as PKE (PASSIVE-KEYLESS-ENTER), is typically used in conjunction with a keyless start system. In the industry, it is generally referred to as PEPS, or Passive-Entry & Passive-Start. The PEPS system utilizes RFID wireless radio frequency technology, allowing entry into the vehicle without pressing the remote key. 2. Principle: Specifically, both the key and the vehicle's related modules are equipped with wireless communication transceivers. The vehicle can detect the key within a certain range. When the owner approaches the car with the key, the two will authenticate each other. Once the authentication is complete, simply pressing the door handle switch or touching the door handle's sensor area will automatically unlock the doors. When the owner moves a certain distance away from the car with the key, the vehicle will automatically lock and enter an anti-theft alert mode.

What brand is the XC90 transmission?

Volvo XC90's transmission brand is an automatic transmission (AT). When replacing transmission fluid, since different automatic transmissions have varying internal structures, friction components, and sealing components, the original factory fluid is specially formulated based on the transmission's structure and materials. Therefore, it is essential to use the manufacturer-specified automatic transmission fluid during replacement. Relevant information about the transmission is as follows: 1. Introduction: A device that changes the speed ratio and direction of motion. It is used to alter the torque, speed, and direction of motion transmitted from the driving shaft to the driven shaft under different working conditions. A gear-driven transmission generally consists of a housing and several gear pairs. 2. Function: While driving, to adapt to different operating conditions, the vehicle's driving force and speed need to vary within a certain range. However, the existing engine's torque and speed variation range cannot meet this requirement, hence the installation of a transmission.

Why is there water dripping from the car chassis?

Reasons for water dripping from the car chassis: During summer, the high temperature inside the car usually requires the cooling system to be activated to lower the interior temperature. At this time, the moisture in the hot air inside the car will condense on the surface of the very cold evaporator heat-absorbing fins, and the water droplets are collected by the plastic casing of the evaporator and drained out of the car through pipes. This is a normal phenomenon. Water dripping from the muffler and exhaust pipe at the rear of the car is also normal. When gasoline is injected into the cylinder and mixed with air, it burns completely in the combustion chamber, mainly producing carbon dioxide and water. The water is discharged into the atmosphere in the form of gaseous water vapor at high temperatures. Since the muffler is located at the rear of the car where the temperature is relatively low, the water vapor will condense into liquid water when it encounters the cold. Some of this liquid water, driven by the high-speed operation of the engine and the airflow, is discharged from the exhaust pipe, resulting in the phenomenon of water dripping or even spraying from the exhaust pipe.
