In-car 2.5 filtration device refers to the PM2.5 filtration device. Below is an introduction to car air filters: 1. Introduction: A car air filter is an item that removes particulate impurities from the air inside the car. The car cabin air filter can effectively reduce pollutants from entering the vehicle through the heating, ventilation, and air conditioning system, preventing the inhalation of harmful pollutants. 2. Classification: (1) Oil filter: The oil filter is located in the engine lubrication system. Its upstream is the oil pump, and downstream are the various engine components that require lubrication. (2) Fuel filter: Fuel filters are divided into carburetor and fuel injection types. (3) Car air filter: The car air filter is located in the engine intake system and is an assembly composed of one or several clean air filter components.

How to Deal with Scratches Inside the Car?

Here is a detailed introduction on how to handle scratches inside the car: 1. Minor Scratches: Minor scratches can be resolved by waxing. Small scratches only affect the car's paint surface and do not damage the deeper layers of the paint. Waxing can completely repair them. If you're unsure, you can go to a car wash or a 4S shop for treatment. 2. Slightly Larger Scratches: For scratches where the car's paint surface is slightly more damaged, waxing alone won't suffice. You can purchase a touch-up paint pen for repair, but pay attention to the color quality of the touch-up paint pen. If the color of the touch-up paint pen differs from the car's body color, the repaired area may look less aesthetically pleasing. 3. Scratches Exposing the Primer: For larger scratches that expose the primer, it's necessary to go to a professional repair shop for treatment.

What is the Difference Between Hybrid and Plug-in Hybrid?

The differences between plug-in hybrid electric vehicles (PHEVs) and regular hybrid vehicles include the ability to charge the battery from an external power source, classification as new energy vehicles, power sources, battery size, fuel economy, and development trends. Ability to charge from an external power source: Regular hybrid vehicles cannot charge the battery from an external power source, whereas plug-in hybrid vehicles can. Classification as new energy vehicles: Plug-in hybrid vehicles are classified as new energy vehicles, while regular hybrid vehicles are not. Power sources: Hybrid vehicles, like conventional gasoline cars, only require refueling. Plug-in hybrids, however, need both refueling and charging. Battery size: Hybrid vehicles charge their batteries through steady-speed driving, slow-speed driving, and braking. Their batteries are much smaller, typically supporting only about 3 kilometers of pure electric driving. The electricity is mainly used to supplement engine power during rapid acceleration, keeping the engine in its most fuel-efficient state. Plug-in hybrid vehicles have larger batteries, usually enabling around 60 kilometers of pure electric driving. They are closer to pure electric vehicles compared to regular hybrids. Their electricity comes not only from the same methods as hybrids but also from direct external charging. Fuel economy: Plug-in hybrids offer longer pure electric driving ranges, better fuel economy, and lower emissions than regular hybrids. The biggest advantage of plug-in hybrids is their longer range compared to pure electric vehicles, while still offering better fuel economy than gasoline-only or regular hybrid vehicles. Development trends: Plug-in hybrids serve as a transitional product between gasoline-only and pure electric vehicles. Electric vehicles represent the future of automotive trends, offering many advantages over internal combustion engine vehicles. Like pure electric vehicles, plug-in hybrids can be registered with green license plates, whereas regular hybrids cannot. Electric motors operate without excess vibration or noise, providing superior cabin quietness. Their power delivery is better suited for stop-and-go city driving, as they can deliver maximum torque instantly, unlike internal combustion engines, which require reaching a certain RPM.

What is the working principle of disc brakes?

Here is a detailed introduction to the working principle of disc brakes: 1. During braking: When braking, the brake fluid is pressed into the inner and outer wheel cylinders. Under hydraulic pressure, the pistons push the two brake pads against the brake disc, generating frictional torque to achieve braking. 2. Deformation occurs: The edges of the rectangular rubber sealing rings in the wheel cylinder grooves undergo slight elastic deformation due to the friction from the pistons. Below is additional information about disc brakes: 1. Types: There are hydraulic types, controlled by hydraulic pressure, with main components including the brake disc, wheel cylinder, brake caliper, and oil pipes. 2. Advantages: Fast heat dissipation, lightweight, simple construction, and easy adjustment. Particularly, they perform well under high loads with good high-temperature resistance and stable braking performance.

What Causes the Metallic Sound When Accelerating a Car?

The reasons for metallic noise when accelerating a car are as follows: 1. Clutch malfunction: Additionally, you can try pulling out the oil dipstick and checking if there is any abnormal noise when stepping on the accelerator. If there isn't, it might be a clutch issue. The turbocharger produces compressed air flow noise during operation. When the engine is revving up or the accelerator pedal is pressed deeply, the engine noise becomes louder. Press the accelerator gently, not all the way down, as stepping on it abruptly can cause this abnormal noise. 2. Loose dashboard or workbench: The engine needs to intake a large amount of air during operation. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, accelerating the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder can cause severe "cylinder scoring." The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder.
