Why Does the Car Air Conditioning Compressor Keep Starting and Stopping Repeatedly?

Frequent start-stop cycling of the car air conditioning compressor indicates a compressor protection malfunction. The specific reasons are as follows: 1. Overheating protection: Prolonged operation due to insufficient refrigerant (system low on Freon); prolonged operation due to system blockage (ice blockage or dirt blockage); excessively high ambient temperature; damaged compressor overheating protection device. The compressor can restart once its temperature decreases. You can pour water on the compressor for rapid cooling, then investigate the cause of the protection trigger. 2. Overcooling protection: Extremely low ambient temperature (below -15°C). 3. Overcurrent protection: Damaged starter capacitor; prolonged operation due to excessive refrigerant charge; low voltage; compressor internal failure.

What types of oil pumps are commonly used in automatic transmissions?

In the oil supply system of automatic transmissions, there are two types of oil pumps: fixed displacement pumps and variable displacement pumps: 1. Commonly used fixed displacement pumps include: (1) Internal gear pumps: Internal gear pumps are the most widely used type of oil pump in automatic transmissions. They feature compact structure, small size, light weight, strong self-priming capability, and minimal flow fluctuation. (2) Rotor pumps: These are a type of internal gear pump with special tooth profiles, characterized by simple structure, compact size, smooth operation, and excellent high-speed performance. (3) Vane pumps: Composed of a stator, rotor, vanes, housing, and pump cover, they have a complex structure and are sensitive to hydraulic oil contamination. 2. Variable displacement pumps are designed by modifying the vane pump in automotive automatic transmissions to have variable displacement. The oil delivery volume of a variable displacement pump stops increasing once the engine speed exceeds a certain threshold, thereby reducing the operational resistance of the pump at high speeds and improving the vehicle's fuel economy.

What does cruise mean in a car?

Refers to the car's electronic cruise control system. When this system is activated, the driver can set the vehicle to maintain a fixed speed, allowing the car to accurately travel at the preset speed. Cruise control should not be used in the following situations: 1. In principle, cruise control is designed for use on highways or fully enclosed roads. On non-enclosed roads, complex road conditions can compromise traffic safety. 2. It is prohibited in rainy weather and snowy/icy conditions. 3. It should be disabled on winding mountain roads or roads with excessive curves. Under normal circumstances when navigating curves, appropriate acceleration is needed to provide greater steering force. In cruise control mode, the vehicle automatically maintains a constant speed with the throttle controlled by the onboard computer, which can often pose dangers when driving on curved roads. Under such conditions, the speed should be appropriately controlled. 4. Cruise control is also unsuitable on roads with heavy traffic.

Under normal circumstances, how many years should tires be replaced?

After 2-3 years of use, small cracks will gradually appear on the sidewalls of the tires. If a large number of fine cracks are found on the tire sidewalls, the tires need to be replaced. The following is relevant information about tires: 1. The wear lifespan of tires is 30,000-50,000 kilometers. If the tires have not reached the wear limit or mileage, but have been in use for 5 years or have developed numerous cracks on the sidewalls, they should be replaced. 2. The main component of tires is rubber, and the maximum storage and anti-aging time for rubber, from natural latex to EPDM and nitrile, does not exceed 10 years. The average service life of various rubber products in use is 3-5 years. 3. Tires bear the weight of the entire vehicle, often serve to cushion impacts, and must also resist corrosive rainwater and car wash cleaning solutions. Therefore, the aging of tires can be significantly accelerated.

What is the reason for the persistent yellow light on the MG6 tire pressure monitoring system?

The reason for the persistent yellow light on the MG6 tire pressure monitoring system is that the tire pressure in one of the MG6's tires is too low. High-speed operation increases the tire temperature, leading to a rise in tire pressure, which triggers the yellow light on the tire pressure monitoring system. The reset method is as follows: first, turn on the ignition switch, then press and hold the tire pressure monitoring reset button until you hear a "ding" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the fault light on the dashboard will turn off, completing the tire pressure reset. Tire pressure monitoring automatically monitors the tire pressure in real-time during vehicle operation and alerts the driver to tire leaks and low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect tire pressure monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of both systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.
