The causes of body shaking in a vehicle with loose brakes may include dirty throttle valves, faulty spark plugs, aged rubber ball joint covers, and worn brake pads. Below is a detailed introduction about automotive braking systems: 1. Overview: Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking involves fixing a wheel or disc on the high-speed shaft of the machine and installing corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force. 2. Brake Pads: Automotive brake pads, also known as brake linings, refer to the friction materials fixed on the rotating brake drum or brake disc of the wheel. The friction linings and blocks within them bear external pressure to create friction, thereby achieving the purpose of vehicle deceleration.

What Refrigerant is Used in Cars?

Commonly used automotive air conditioning refrigerants include: Freon-12, R134A, and natural refrigerants. Freon-12 is a non-environmentally friendly refrigerant and is rarely used nowadays; R134A is a relatively eco-friendly refrigerant. Below is a detailed introduction: 1. Freon-12 (Code: R12) R12 is a halogenated hydrocarbon, scientifically known as dichlorodifluoromethane. It is a medium-pressure, medium-temperature refrigerant widely used in small and medium-sized refrigeration systems in China. It is a colorless, transparent, odorless, almost non-toxic, non-flammable, non-explosive, and very safe refrigerant. 2. R134A. Widely used for initial installation in new refrigeration and air conditioning equipment and for replenishment during maintenance, it is currently the most widely used medium-to-low temperature environmentally friendly refrigerant. 3. Natural refrigerants. Ozone layer depletion and global climate change are the main environmental issues currently facing the world. Due to the widespread use of CFCs and HCFCs in refrigeration and air conditioning, which damage the ozone layer and contribute to the greenhouse effect, the global industry faces significant challenges.

What does it mean when the ECO light turns green?

When the ECO indicator light on the car is illuminated, it indicates that the vehicle's economy mode has been activated. ECO is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The ECO mode is further divided into active ECO driving mode and passive ECO driving mode. The ECO mode is categorized into active and passive types, with the difference being that the active type has its own dedicated button, allowing the driver to choose whether to enable it. When the driver presses the ECO mode switch, the dashboard indicator light immediately illuminates, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The passive ECO mode does not have a dedicated button; when the dashboard ECO indicator light comes on, it serves merely as a reminder function. The ECO system automatically evaluates your driving behavior, and if your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the ECO indicator light. Most cars employ the active ECO driving mode, meaning they have their own switch button. Therefore, during daily driving, we can generally enable the ECO mode. However, it is unnecessary to activate the ECO mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode, especially when climbing hills. Doing so would not only fail to demonstrate the fuel-saving characteristics of the ECO mode but also negatively impact the vehicle's power performance. Additionally, the ECO mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the ECO mode to automatically deactivate. During idle parking or when in N/P gear or manual mode, the ECO mode may also become ineffective. When a high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the ECO mode will not operate under these conditions either.

How to Extract Excess Engine Oil?

Excess engine oil can be extracted using a long suction tube paired with a shampoo nozzle. The specific method is as follows: 1. Purchase a soft tube longer than the oil dipstick. With the engine cold, insert the tube into the dipstick port, connect the shampoo nozzle end to a plastic water bottle, and press the nozzle to extract the oil. Check the oil level with the dipstick once the extraction is nearly complete. 2. During an oil change, traditional gravity drainage is more reliable than oil extraction. Many vehicle models do not achieve thorough oil extraction via suction. For models with the oil filter located in the lower half of the engine, gravity drainage is the preferred method for changing both the oil and oil filter. Otherwise, even after suction, the engine guard plate would still need to be removed to replace the oil filter.

What are the reasons for a car automatically stalling and failing to start?

The reasons for a car suddenly stalling and failing to start are as follows: 1. No fuel: Failure to observe the fuel tank usage, with the fuel gauge showing below the red line, naturally results in failure to start. 2. Dead battery: This could be due to prolonged headlight usage without turning them off, leading to battery drain, or the battery reaching the end of its lifespan. It is generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures. Checking for a dead battery is simple—just press the horn to find out. 3. Wrong gear: For automatic transmission cars, the gear must be in P (Park) or N (Neutral) when starting. If it's in R (Reverse) or D (Drive), the car won't start. Similarly, some manual transmission cars won't start if the clutch isn't depressed.

What Causes Brake Disc Noise?

There are several reasons that may cause abnormal noise from a vehicle's brake discs: 1. New car brake noise: The brake pads and discs of a new car have not yet been fully broken in, so they may sometimes produce a "squeaking" friction sound, which is normal. The noise will naturally disappear after some use. 2. Noise after replacing brake discs/pads: After installing new brake pads, incorrect installation may cause noise. Common installation errors include installing the brake pads upside down, with the metal side touching the brake disc, resulting in abnormal noise. 3. Worn brake discs causing noise: Prolonged use can cause deep grooves on the brake disc surface or deep steps on the edges. Uneven contact between the brake pads and the disc can create noise. In this case, the brake discs need to be replaced or polished using a brake disc resurfacing machine. 4. Sand or debris in brake discs causing noise: If foreign objects like sand or small stones get between the brake pads and discs while driving, the brakes may produce a harsh hissing sound. Continuing normal driving will usually allow the debris to fall out, eliminating the noise. If the noise persists, the wheel may need to be removed to extract the debris. 5. Noise during hard braking: When braking hard, if you hear a clicking sound and feel vibration in the brake pedal, this is a normal phenomenon caused by the ABS system activating.
