When the clutch alternates between being hard and soft, it is typically an issue with the clutch master cylinder. The reasons for this fluctuation include: over time, dust can accumulate inside the clutch cable, throttle cable, or choke cable, causing them to operate less smoothly. Solutions: 1. Use rust penetrant spray—disconnect the upper end of the cable, spray the penetrant between the wire and its sheath, then pull it back and forth repeatedly. You will notice black, dirty fluid dripping from the lower end. Wipe it clean with a rag and apply a small amount of engine oil. 2. Replace two of the springs—open the clutch side cover to locate the four springs on the clutch. Replace two diagonally opposite springs with ones that have slightly less tension.

What does front mean?

On a car's air conditioning system, "front" refers to the function of defogging the front windshield. It is usually represented by a fan-shaped symbol with several upward wavy arrows and the word "FRONT" at the bottom. Similarly, "REAR" indicates the button for defogging the rear windshield. Here are some additional details: 1. While driving, when there is a significant temperature difference between the inside and outside of the car, fog may form on the windshield, which can severely obstruct the driver's view. In such cases, you can press either the "FRONT" or "REAR" button, depending on whether the fog is on the front or rear windshield, to remove the fog. 2. When driving, it's also important to pay attention to the use of the internal and external air circulation systems. If you're driving for an extended period, it's advisable not to keep the internal circulation on continuously, as this prevents fresh air from entering the car, which is not good for the occupants.

What brand of car is AIRBAG?

What is the Function of a Car Exhaust Valve?

The function of a car exhaust valve is to allow a portion of the exhaust gases to recirculate back into the combustion chamber. This small amount of exhaust gas helps lower the temperature inside the cylinder during combustion. Since NOX (nitrogen oxides) are produced under high-temperature and oxygen-rich conditions, this process inhibits NOX formation, thereby reducing NOX emissions in the exhaust. Hazards of a Damaged Exhaust Valve: It loses its oil-gas separation function, causing oil to be sucked into the combustion chamber along with the intake air. This leads to oil burning and blue smoke emissions. Additionally, if the exhaust valve malfunctions or is damaged, it cannot properly control the exhaust gas recirculation rate. Excessive exhaust gas recirculation affects the air-fuel mixture concentration, resulting in difficulties starting the engine, engine shaking, unstable idling, poor acceleration, and overall reduced engine performance. Causes of Exhaust Valve Damage Include: Poor quality of the exhaust valve itself. Improper maintenance. Low-quality fuel.
