What are the solutions for compressor overheating protection?

The solutions for compressor overheating protection are: 1. Appropriately adjust the limit value of the high relay; 2. Check the remaining amount of refrigerant; 3. Use high-pressure nitrogen to flush the pipeline and clear the expansion valve blockage. The methods to determine the condition of the car compressor are: 1. Start the engine and maintain the speed at 1250 to 1500 rpm; 2. Connect the manifold pressure gauge to the air conditioning refrigeration system, turn on the AC switch, and set the fan to the maximum position; 3. Touch the intake and exhaust ports of the compressor. If the intake port is cool and the exhaust port is hot with a significant temperature difference between them, the compressor is in good condition; otherwise, it is damaged. The working principle of the car compressor: It draws refrigerant from the low-pressure area, compresses it, and sends it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the radiator, and the refrigerant changes from a gaseous state to a liquid state, resulting in increased pressure.

What does it mean when the SVS light appears on the vehicle dashboard?

When the SVS light appears on the vehicle dashboard, it means that the engine control unit has detected an error signal from a sensor or that the signal exceeds the standard usage range. The working principle of SVS is: when the ignition key is turned on, the light comes on and turns off after the vehicle starts. If the engine ECU detects a fault, the SVS light will illuminate. If the light comes on while driving, it indicates a fault in the vehicle's engine. The dashboard is a rigid panel or structural component used to install instruments and related devices. Common indicator lights on the dashboard include: 1. Coolant level warning light; 2. Fuel level indicator; 3. Washer fluid level indicator; 4. Charging indicator; 5. High/low beam indicator; 6. Transmission gear indicator; 7. Anti-lock braking system (ABS) indicator; 8. Traction control indicator; 9. Airbag warning light.

What is the direction of car tire screws?

The tightening direction for car tire screws is clockwise, while the loosening direction is counterclockwise. When using a jack, always place it in the jack slots located on both sides of the vehicle's underside to prevent accidents. Whether tightening or loosening screws, always follow the diagonal sequence when turning the screws. This ensures that the stress on the tire is evenly distributed, making the process easier and reducing wear on the screws. Whether tightening or loosening screws, it's important to note that when the vehicle is raised with a jack, avoid applying excessive force to tighten the screws. Too much force may cause the vehicle to sway, leading to misalignment of the jack and potential harm to people or the vehicle. For large trucks, the direction of the tire screws differs between the left and right sides. The left side uses reverse threads, while the right side uses standard threads. This means tightening is done by turning in the direction of the vehicle's forward motion, and loosening is done by turning in the reverse direction. After loosening, it's essential to visit a professional auto repair shop to have the tires inspected, ensuring no safety hazards are overlooked due to negligence.

What does a fan symbol on the vehicle dashboard represent?

A fan symbol on the vehicle dashboard represents the air conditioning airflow control button. The car air conditioning system primarily has three basic adjustments: airflow volume, temperature, and wind direction. The first is the airflow control button, also referred to as the fan speed button, which is marked with a small "fan" symbol. By rotating this button, you can select the appropriate airflow volume. More details are as follows: 1. Temperature control button: Typically displayed as a "thermometer" or marked with blue and red color indicators at both ends. Rotating the knob towards the red area gradually increases the temperature, while the blue area does the opposite, gradually decreasing the temperature. 2. Wind direction adjustment: Generally available in button or knob forms, these are more straightforward and clearly marked with a "seated person plus wind direction arrow" symbol. As shown, you can choose to direct air to the head, head and feet, feet, feet and windshield, or solely to the windshield. The air vent adjustments for most vehicles follow this pattern, with only a few exceptions.

What is the problem with the air conditioner not blowing air?

The problem of the air conditioner not blowing air is: 1. The indoor unit is not connected to the power supply; 2. The temperature of the indoor heat exchanger is low; 3. The outdoor heat exchanger is frosted; 4. The air conditioner compressor is damaged. The functions of the car air conditioner are: 1. To adjust and control the temperature, humidity, air cleanliness, and air flow inside the compartment to an optimal state; 2. To provide a comfortable riding environment for passengers and reduce travel fatigue; 3. To create good working conditions for the driver and ensure driving safety. Things to note when using the air conditioner: 1. Choose an appropriate air conditioner temperature; 2. Do not immediately start the internal circulation when entering the car in summer; 3. Do not keep the air conditioner on for a long time; 4. Do not adjust the air outlet direction arbitrarily; 5. Use the air conditioner in a fully enclosed state; 6. Do not rest or sleep for a long time in a parked car with the air conditioner on.

What is the adjustment method for single-cylinder valve clearance in diesel engines?

Adjustment method for single-cylinder valve clearance in diesel engines: 1. Before adjusting the valve clearance, first remove the cylinder head cover. Rotate the crankshaft to align the timing mark on the flywheel with the 0 scale line. At this point, cylinders 1 and 6 of the diesel engine are at top dead center; 2. Identify the cylinder at top dead center at the beginning of the expansion stroke. Slightly rotate the crankshaft and observe whether both the intake and exhaust valves are stationary; 3. Adjust the valve clearance. Use a wrench and screwdriver to loosen the lock nut and adjusting screw on the rocker arm. Insert a feeler gauge of the specified thickness between the rocker arm and valve, then turn the adjusting screw for verification. When the rocker arm and valve are in contact with the feeler gauge but the gauge can still be moved slightly, tighten the nut. Finally, recheck by moving the feeler gauge again; 4. After adjusting the valves, rotate the crankshaft 360 degrees and complete the valve clearance adjustment using the two-step adjustment method.
