What Causes a Compressor to Fail?

Compressor failure can be caused by the following situations: 1. Winding short circuit, open circuit, and winding grounding to the casing: These faults are caused by the motor part of the compressor. When an open circuit occurs, the power supply is normal, but the compressor does not work. In cases of short circuit or grounding, the protector trips or the fuse blows when power is applied. If there is a slight inter-turn short circuit in the winding, the compressor can still operate, but its temperature becomes very high, the operating current is very large, and the thermal protector will trip shortly after operation. A multimeter can be used to check for open circuits and winding grounding to the casing. Slight winding short circuits are difficult to determine and should be judged based on current measurements. 2. Compressor vibration and noise: This often occurs during maintenance. Generally, it does not significantly affect refrigeration performance, but users may feel it is abnormal. The main causes include contact between pipes and the casing, detachment of damping blocks, and loosening of compressor mounting bolts. 3. Poor sealing of compressor suction and discharge valves: If the compressor's suction or discharge valves are damaged, even with sufficient refrigerant, the system cannot establish high and low pressure or may struggle to achieve qualified high and low pressure, resulting in no refrigeration or poor refrigeration performance. 4. Compressor seizure or stuck piston: The main causes of these faults are lack of oil or the entry of impurities. After power is applied, the compressor does not operate, and the protector trips.

How to Locate the Reverse Light Wire?

First, locate the reverse switch which has two wires. The one with power is connected to the fuse panel, while the one without power leads to the rear reverse light. Follow the wire colors to identify them. Typically, blue and green wires indicate left and right turn signals respectively, red is the positive wire, black is the ground, and reverse lights are usually connected to brown or gray wires.

What's the Difference Between Plug-in Hybrid and Hybrid Electric Vehicles?

There are several key differences between plug-in hybrid and hybrid electric vehicles: 1. Plug-in hybrids have two drive systems that can completely power the car in pure electric mode, such as BYD's Qin and Tang models. Hybrid electric vehicles are non-plug-in hybrids, like the Toyota Prius, Corolla Hybrid, Camry Hybrid, Kia Niro, and Honda CR-V Hybrid. 2. Hybrid vehicles have very small battery capacities that only supply/recover energy during start/stop and acceleration/deceleration. They cannot be charged externally and cannot operate in pure electric mode. Plug-in hybrid vehicles have relatively larger batteries that can be charged externally and operate in pure electric mode. Once the battery is depleted, they switch to hybrid mode (primarily powered by the internal combustion engine).

Will traffic violation notifications be received on weekends?

Traffic violations are not limited to Saturdays or Sundays. As long as your mobile number is registered, you will receive SMS notifications. Generally, vehicle owners will receive free SMS alerts about traffic violations within 2 days after the offense. Vehicle owners can also check, pay fines, and handle non-point traffic violations through the "Public Security Public Service Website." Other violations that involve points must be processed at the service window. Whether violations can be handled on weekends depends on the policies of each city. For example, currently, cities like Jinan and Qingdao allow processing violations on weekends. Required materials for handling vehicle violations: driver's license, vehicle registration certificate, violation confirmation notice, and ID card. Most violations are now recorded by electronic surveillance, reviewed, and entered into the system. Vehicle owners can check their violation records online, typically within 3 to 13 days (excluding Saturdays and Sundays). Vehicle violations refer to acts where motor vehicles violate road traffic safety laws and traffic management regulations. Penalties for vehicle violations include warnings, fines (vehicle impoundment), temporary suspension of the driver's license, revocation of the driver's license, cancellation of the driver's license, administrative detention, and criminal liability for offenses that constitute a crime. Vehicle owners can check their violation records through mobile apps like Wheel Violation Check.

Can the odometer of a sedan be adjusted?

The odometer of a car can be adjusted, and the specific methods are as follows: 1. Locate the sensor plug on the clutch housing of the car (the position of the sensor plug varies depending on the model, some may be on the transmission or the odometer of the drive shaft), then gently pull it out by hand; 2. Insert the output tab of the odometer adjuster into the signal hole of the pulled-out sensor plug, and accurately insert the odometer adjuster into the cigarette lighter; 3. Turn on the car key, rotate it slightly, adjust the knob on the odometer adjuster, and set the car's speed to the desired speed to adjust the odometer.
