Negative ions are ions carrying a negative charge. Due to their small size, they can form an adsorption effect when encountering harmful substances in the air. Therefore, if the car's purifier has a negative ion function, it is very useful for sterilization, especially for well-known brands with strong R&D capabilities that can release 6 million negative ions, such as the Yupin purifier, which has even stronger sterilization capabilities. Below is an introduction to the purifier: 1. A car purifier, also known as an automotive purifier or in-car air purifier, typically consists of a high-voltage circuit negative ion generator, a micro-fan, an air filter, and other systems. 2. Its working principle: The micro-fan (also known as a ventilator) inside the machine circulates the air in the car. Polluted air passes through the PM2.5 filter and activated carbon filter inside the machine, where various pollutants are filtered or adsorbed. Then, the air is continuously ionized by the negative ion generator installed at the air outlet (which produces a DC negative high voltage when working), generating a large number of negative ions. These negative ions are then blown out by the micro-fan, forming a negative ion airflow to achieve the purpose of cleaning and purifying the air.

What's the reason when the steering wheel isn't locked but the key won't turn?

The reason why the steering wheel isn't locked but the key won't turn: The steering wheel is locked. After the vehicle is turned off, the steering wheel will automatically lock as a simple anti-theft feature. When the vehicle is started with the key, the steering wheel will automatically unlock. However, sometimes when parking, if the steering wheel is positioned at a certain angle where the key can be turned to ignite but not unlock the steering wheel, this phenomenon occurs. You can gently turn the key with your right hand while lightly turning the steering wheel with your left hand, and the steering wheel will naturally unlock. The steering wheel is the wheel-shaped device used to control the direction of cars, ships, airplanes, etc. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft.

What Causes Abnormal Noise During Low-Speed Braking in Cars?

Abnormal noise during low-speed braking in cars can be attributed to the following reasons: 1. The vehicle is in the break-in period; 2. Malfunctions in the caliper, brake disc, or brake pads causing abnormal noise; 3. Severe wear of the brake pads can also lead to abnormal noise during low-speed braking. If the noise persists, the first step is to check for any dragging brakes, as poor caliper resetting can cause prolonged friction of the disc, resulting in abnormal noise under certain conditions. If the noise occurs immediately after installing new brake pads, it indicates that the new pads and friction blocks are of inconsistent sizes, causing the noise. For new vehicles in the break-in period, such noise is normal as new brake pads and discs require a break-in process. When braking, if the hard spots on the brake pads are encountered, this type of noise may occur. Additionally, the presence of sand, gravel, or other debris on the brake pads or discs can also produce such noises.

How to Set Up One-Touch Window Control for the Honda Vezel?

Honda Vezel one-touch window control setup method: First, start the vehicle, press and hold the switch to lower the window completely for 5 seconds, then press and hold to raise the window completely for another 5 seconds before releasing. Once completed, the one-touch function will be activated. Currently, only the driver's window is equipped with the one-touch feature; the other three windows operate on a press-to-move basis. The Vezel is a compact SUV under the Honda brand, equipped with two engine options: a 1.5L naturally aspirated engine and a 1.5L turbocharged engine. The 1.5L naturally aspirated engine delivers a maximum power of 96 kW and a maximum torque of 155 Nm, while the 1.5L turbocharged engine offers a maximum power of 130 kW and a maximum torque of 220 Nm. Both engines incorporate VTEC technology and direct fuel injection, and utilize aluminum alloy cylinder heads and blocks.

How to Extract Gasoline from a Motorcycle?

Methods for extracting gasoline from a motorcycle: 1. Turn off the fuel line switch under the fuel tank. There is a fuel line between the fuel line switch and the carburetor. Pull out the fuel line connected to the carburetor and place it into a pre-prepared container. 2. Insert a tube into the fuel tank opening until it reaches the bottom, then lower the tube below the fuel tank level. Gently blow into the tube and then suck out the gasoline, using a container to catch it below. Simply replacing the engine oil without changing the oil filter is not advisable. During the lubrication process, the oil pump draws oil from the sump and first presses it into the oil filter for purification. The filtered clean oil is then transported to the cylinder head, crankshaft, and transmission parts. If the filter is too dirty, the oil filtration efficiency decreases, reducing the output oil volume. Without proper lubrication, excessive wear can occur. Therefore, it is essential to replace both the engine oil and the oil filter simultaneously.

Can the China VI GPF be removed?

The China VI GPF cannot be removed. The GPF is equipped with a pressure sensor, and it is estimated that the engine control system will report a fault after removal. The Gasoline Particulate Filter (GPF) is a ceramic filter installed in the gasoline engine emission system, which captures particulate emissions before they enter the atmosphere. Removal will result in non-compliance with particulate emission standards. Here is additional information about the GPF: 1. The filtration mechanism of the GPF is basically the same as that of the diesel engine's DPF. Exhaust gas flows through the porous wall at a certain velocity, a process called "Wall-Flow." 2. The wall-flow particulate filter consists of a honeycomb ceramic with a certain pore density. By alternately blocking the honeycomb porous ceramic filter body, the exhaust flow is forced to pass through the wall of the channel, and the particulate matter is captured and filtered through four methods: diffusion, interception, gravity, and inertia. 3. There are three main forms of GPF arrangement on the gasoline engine exhaust pipe. One is integrated with the TWC and installed close to the exhaust manifold, known as the closed-coupled arrangement. Another is installed directly downstream of the TWC, known as the under-floor arrangement. There is also a method where the three-way catalyst is coated on the GPF substrate to form a "four-way catalyst." 4. After prolonged use of the particulate filter, soot particles accumulate on the surface of the filter's micropores, forming a PM layer, which gradually reduces the storage volume. The formation of the PM layer helps improve filtration efficiency, but a throttling effect occurs in the exhaust pipe, increasing exhaust flow resistance, leading to increased fuel consumption and reduced engine output power. At this point, the GPF needs to be replaced or regenerated.
