What Causes the Car's Air Conditioning Compressor to Vibrate?

Here are the reasons for the vibration when the air conditioning is turned on: 1. Excessive carbon buildup: If the engine's throttle has not been maintained for a long time, it can easily accumulate carbon deposits. These deposits obstruct the engine's intake system, leading to incomplete engine intake. As a result, the engine may struggle or barely manage to drive the compressor, causing idle vibration. 2. Damaged spark plugs: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Spark plugs are car parts that are prone to wear and tear. Poor spark plug performance can cause the engine to vibrate during startup, affecting the engine's power output. Combined with the pressure from the compressor, this can lead to vibration when the air conditioning is on. If the spark plugs have excessive carbon buildup or are damaged, it is recommended to replace them directly.

How wide is 30 centimeters in the rearview mirror?

30 centimeters in the rearview mirror is roughly the width of two fingers. When taking the driving test, there are some tips and methods to determine the 30-centimeter distance in the rearview mirror: 1. Observe the wiper protrusion: From the driver's seat, when the wiper protrusion aligns with the right-side line, the distance is approximately 30 centimeters. 2. Look at the one-third point of the car's front: When the right one-third of the car's front aligns with the right-side line, the distance is exactly 30 centimeters. It might be difficult to find this one-third point, as it may not always be the same spot. During practice, you can mark this point on the car and remove the mark once you get used to it. 3. Check the right front door handle: Observe the right front door handle in the right rearview mirror. If the handle is tangent to the right-side line, the distance is correct. If it's too far, adjust the direction slightly. If it's too close, there's a risk of crossing the line.

What are the pros and cons of modifying a 300-cell header?

Pros and cons of modifying a 300-cell header: 1. Pros: Smoother exhaust flow, strong high-RPM horsepower. Exhaust modifications come in various forms, with many aimed solely at achieving a pleasing sound. More professional modifications involve adjusting the exhaust to better match engine upgrades, allowing the engine to perform at its peak. 2. Cons: Direct exhaust emissions fail to meet standards. Most modified straight-pipe exhaust systems suffer from weak low-RPM performance, increased noise, and excessively loud volume. Untreated exhaust emissions exceed limits, causing severe pollution, unpleasant odors that can enter the cabin, and higher fuel consumption.

What does it mean when a car boils over?

Car boil-over typically refers to a situation where the engine's operating temperature exceeds the normal working temperature range, affecting machine operation and potentially causing damage. Below are relevant explanations about car boil-over: 1. Causes of boil-over: There are many reasons for car boil-over. Besides hot weather, overloaded air conditioning operation and faulty cooling components can also cause boil-over. Conducting a comprehensive inspection of the car's cooling system is the primary method to prevent boil-over. 2. Avoid immediately opening the cap to add water when boil-over occurs: After the radiator water boils, there is internal pressure. If the radiator cap is opened immediately at this time, hot water may spray out, causing burns. Therefore, car owners must avoid opening the cap to add water right after boil-over occurs.

Why doesn't the car horn sound when locking with the key?

Here are the reasons why the locking horn doesn't sound: 1. Poor sealing leading to water ingress: If the seal isn't tight, water vapor can easily enter during car washing, causing the contacts to become damp and malfunction. 2. Poor contact at the electromagnetic coil terminal: If the insulation paint on the enameled wire ends isn't completely removed, or if the rivet crimping is loose, intermittent connection may occur, resulting in the horn not sounding. This type of fault can only be resolved by replacement, not repair. 3. Prolonged horn use causing contact erosion: Holding down the horn for extended periods can cause contact erosion and create impedance. This weakens the current passing through the electromagnetic coil, preventing it from attracting the armature to drive the diaphragm's normal vibration, leading to the horn not sounding. However, when the horn is pressed repeatedly, momentary strong current can still pass through the impedance and function normally, which is why the horn may work intermittently.

Is a mock test necessary for Subject 3?

Subject 3 requires a mock test, but it is not mandatory. Related introduction: 1. Brief description: Subject 3, including the road driving skill test and the safe and civilized driving knowledge test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the road driving skill and safe and civilized driving knowledge test subjects in the motor vehicle driver's examination. The content of the road driving skill test varies for different types of driving licenses. 2. Expansion: The road driving skill test for Subject 3 generally includes: preparation before getting on the car, light simulation test, starting, driving straight, shifting gears, changing lanes, parking by the roadside, going straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, making U-turns, and driving at night.
