What Are the Most Correct Methods for Cleaning a Three-Way Catalytic Converter?

The correct methods for cleaning a three-way catalytic converter are as follows: 1. Adding a cleaning agent to the fuel tank: This method is very common in the market, with the biggest advantage being its low cost and simple operation. You only need to add this type of cleaning agent directly to the fuel tank. However, the cleaning effect this product has on the three-way catalytic converter is minimal. This is because the product is almost completely burned out by the time it reaches the three-way catalytic converter after combustion in the combustion chamber, leaving almost no cleaning effect. 2. Drip cleaning: Drip cleaning, also known as no-disassembly cleaning, is currently the most popular method for cleaning a three-way catalytic converter in the market. The biggest advantage is that it does not require removing the three-way catalytic converter, but the downside is the high cost of purchasing cleaning equipment and the limited cleaning effect. This drip cleaning method uses the intake vacuum to draw the cleaning agent into the combustion chamber. After combustion, it creates a high-temperature oxidation environment inside the three-way catalytic converter, converting sulfur, phosphorus compounds, and unburned residues from gasoline into gases like carbon dioxide and sulfur dioxide, which are then expelled through the exhaust pipe. This restores the activity of the precious metals on the three-way catalytic converter. 3. Disassembly cleaning: Disassembly cleaning is a very time-consuming and labor-intensive method. It requires completely removing the three-way catalytic converter from the vehicle, soaking it in a cleaning agent (such as oxalic acid or toilet cleaner) for a period of time, and then rinsing it with water. In fact, this is the most effective method for cleaning a three-way catalytic converter.

Is the Active Braking System Useful in High-Speed Danger Situations?

Active braking systems are not useful in high-speed danger situations. Below are additional details: 1. Reasons: In terms of speed, the current models on the market equipped with active braking systems are designed for urban use, functioning effectively at speeds below 80 km/h, which is a dynamic speed. At a static speed of 80 km/h, it is practically difficult for the system to be effective. Automakers, considering cost, generally equip vehicles with factory-installed active braking systems using microwave radar. The detection range of microwave radar is about 10 meters, which means it cannot guarantee effectiveness at high speeds. In contrast, laser radar has a detection range of about 150 meters and higher accuracy, making it particularly effective on high-speed roads with high risk factors. However, the cost of laser radar is more than five times that of microwave radar. 2. Active Safety Systems: Active safety systems refer to safety systems that include electronic devices such as ABS and ESP. Passive safety systems involve vehicle body energy-absorbing structures, seat belts, airbags, etc. Among active safety systems, the most typical is the active braking system.

What are the hidden features of the Tiguan?

The hidden features of the Volkswagen Tiguan are as follows: 1. Key: Long-pressing the lock/unlock button can open or close all four door windows (including the panoramic sunroof); When the vehicle is locked, long-pressing the trunk opening button can open the trunk, and closing the trunk door will automatically lock it without needing to press the lock button again; Pressing the unlock button once only unlocks the driver's side door, while pressing it twice within 1 second unlocks all doors. 2. Steering wheel: In the information display screen in the middle of the instrument panel, vehicle driving time, mileage, etc., can be reset immediately by long-pressing the 'OK' button. 3. Headlight 'home' function: After locking or unlocking the car, the headlights automatically turn on for 10 or 20 seconds, etc., and the duration can be set by the user.

How to Reset the Tire Pressure on the Grand Commander?

The tire pressure reset on the Grand Commander can be performed by simply long-pressing the tire pressure reset button. The tire pressure for vehicle tires is generally maintained between 2.3-2.5 bar. As the tires are the only components in contact with the ground, excessively high or low tire pressure can affect their service life. Relevant information about tire pressure reset is as follows: 1. Tire pressure reset is a tire pressure monitoring operation; typically, the system will alert if abnormal tire pressure is detected. 2. The primary purpose of the tire pressure reset function is to monitor tire pressure and ensure safety. 3. When the vehicle detects abnormal tire pressure, the tire pressure warning light will illuminate. After addressing the tire pressure issue, a reset is required to prepare for the next monitoring cycle.

Why Does the Windshield Fog Up in Summer?

Fogging on the inside of the front windshield in summer is caused by the temperature difference between the inside and outside of the car. When the window temperature is lower than the dew point, the moisture content in the air is insufficient to form water droplets, resulting in tiny water particles that condense on the window surface, leading to windshield fogging. Solutions for window fogging: Using detergents: Dishwashing liquid or soap can be used to prevent fogging on car windows. Soften the soap by soaking it in water, then apply it evenly on the glass surface. Once the soap dries, wipe it off with a tissue or newspaper. For dishwashing liquid, mix water and detergent in a 9:1 ratio and spray it on fog-prone windows during rainy days. After drying, gently wipe with a soft tissue to prevent fogging. External circulation defogging: If it rains frequently and opening windows is not suitable, turn on external circulation to defog. Properly adjust the vents to blow air toward the front windshield and footwell or just the windshield. For cars with automatic air conditioning, the compressor may not activate at lower temperatures. In such cases, allow air exchange between the inside and outside of the car to disperse moisture and achieve defogging. Anti-fog spray: There are specialized anti-fog sprays available in the market for car windows. These sprays absorb moisture on the glass surface, forming a water film that prevents fogging. They prevent moisture from adhering to the glass, and wiping the windows with a cloth afterward keeps them clear for a long time. Rolling down windows: After driving outside, park and open the windows to let warm air in. Within two to three minutes, the temperature difference decreases, and the fog will disappear automatically. If stopping is inconvenient, use windshield wipers to remove fog from the front and rear windshields. For side windows, roll them up and down to scrape off fog using the window seals.
