What is the function of engine internal cleaner?

Engine internal cleaner is a product developed to address the issue of deposits. More details are as follows: 1. It is composed of multiple highly effective cleaning components and serves as an additive capable of automatically cleaning the internal lubrication system. 2. When the engine internal cleaner is added to the engine crankcase, it flows with the engine oil during operation, completing the cleaning process. It dissolves gum, loosens bonded deposits, and causes them to detach. Deposits such as varnish, carbon buildup, and sludge on piston rings and piston skirts are thoroughly removed. The dislodged deposits are either filtered out by the oil filter during circulation or settle in the oil pan, to be removed when replacing the oil filter and cleaning the oil pan. 3. Engine internal cleaner mainly consists of surfactants, alkali, chelating agents, detergents, metal corrosion inhibitors, water, etc. The products on the market are primarily categorized into three types: sludge removers, carbon deposit removers, and sludge and carbon deposit removers.

Why is the brake disc squeaking?

The causes of brake disc noise include: 1. Running-in period for new cars or newly replaced brake pads leading to brake noise: New cars or newly replaced brake pads have a running-in period during which some noise may occur. Typically, the noise will disappear after the car has been driven for a few hundred kilometers. 2. Normal activation signal of the ABS system: The noise caused by the activation of the ABS system is normal. 3. Severe wear of brake pads triggering an alarm: Severe wear of brake pads can also cause brake noise. Generally, brake pads have warning indicators. When the brake pads wear to their limit, the warning indicators will rub against the brake disc, producing a sharp sound. At this point, the brake pads should be replaced immediately to avoid accidents. 4. Foreign objects between the brake disc and brake pads: There may be small stones or a water film between the brake disc and brake pads, which can cause noise. You can press the brake pedal several times or remove the small stones.

Can You Feel the Operation of On-Demand Four-Wheel Drive?

On-demand four-wheel drive activates in snowy, muddy, or manhole cover situations. Here are the details about on-demand four-wheel drive: 1. Snowy conditions: On snowy days, if the front wheels slip, this function will engage when the slip is detected. 2. Muddy terrain: On muddy roads where both front and rear wheels slip, the on-demand four-wheel drive starts to work. 3. Manhole covers: If the clutch slips when falling into a manhole cover, producing a foul-smelling smoke, the four-wheel drive will also activate. 4. Advantages of on-demand four-wheel drive: Compared to full-time four-wheel drive, on-demand four-wheel drive has a much simpler structure, which not only effectively reduces costs but also helps lower the overall vehicle weight. 5. Disadvantages of on-demand four-wheel drive: It also has drawbacks. Most on-demand four-wheel drive systems are limited by structural flaws when transferring power between the front and rear axles, unable to deliver more than 50% of the power to the rear axle.

What to Pay Attention to When Buying a Used Volkswagen Phaeton?

If you want to buy a used Volkswagen Phaeton, you must carefully check whether the car is a flood-damaged or fire-damaged vehicle, and whether it has been involved in any major accidents. Basically, if these issues are ruled out, you can purchase a good car. More relevant information is as follows: 1. Introduction: The Volkswagen Phaeton is a luxury sedan produced by Volkswagen AG in Germany, officially launched in mass production in 2002. Its competitors include the Mercedes-Benz S-Class, BMW 7 Series, and Audi A8. 2. Configuration: The first-generation Volkswagen Phaeton debuted at the Geneva International Motor Show in 2002, marking Volkswagen's first full-size luxury sedan, which is of great significance. In response to changes in the family design, the 2009 facelift version of the Phaeton refined details such as the front face appearance and introduced an FSI direct-injection engine power system. However, for the entire model, the eight years since its launch indicated that its lifecycle was nearing a complete generational update, and the Phaeton's high price is attributed to its rare W12 engine, which is uncommon in global sedans.

What is the function of APS in a car?

APS on the car's central console refers to the central control system of the vehicle. The car's central control is the area that manages comfort and entertainment devices such as the air conditioning and audio system. The central control includes the central door lock system, allowing the driver to control the opening and closing of all doors and the window lift system. It also encompasses the central console, which houses various vehicle controllers like the audio control panel. Information about APS is as follows: 1. Central Control: When the driver locks the door next to them, all other doors lock simultaneously. The driver can unlock all doors at once using the door lock switch or open a specific door individually. 2. Speed Control: When the vehicle reaches a certain speed, all doors automatically lock to prevent passengers from accidentally opening them by operating the door handles. 3. Individual Control: Besides the door next to the driver, other doors are equipped with separate spring lock switches, enabling independent control over the opening and locking of each door.

How often should the coolant be replaced in a Lavida?

The coolant in a Lavida is recommended to be replaced every 40,000 kilometers. Below are some precautions to take when replacing the coolant: 1. The most important thing is to wait until the vehicle has cooled down. Never replace the coolant when the engine is at a high temperature. Not only is there a risk of burns, but draining the coolant while the engine is hot can also affect the vehicle's cooling. 2. There are several methods to drain the coolant. A more standardized procedure is to lift the car, unscrew the drain plug at the bottom, and let the coolant drain out through this hole. 3. When adding new coolant, unscrew the drain plug near the "upper hose" and continue to fill with coolant. Once the coolant flows steadily from the drain plug without any air bubbles, tighten the drain plug. 4. You can directly pour about 4 liters of coolant into the reservoir. Stop filling once the fluid level reaches the MAX mark. The engine generates a significant amount of heat during operation, with 60% of this heat being dissipated into the surrounding space through the cooling system.
