What is the function of the in-car PM2.5 filter?

The function of the in-car PM2.5 filter is to filter PM2.5 particles from the air. Air pollution is becoming increasingly severe, especially particles with a diameter of 2.5 micrometers or smaller in the air, which can be absorbed into the human body and pose a threat to health, particularly for sensitive individuals. To meet market demands, various car manufacturers have successively produced vehicles equipped with PM2.5 filters. In-car PM2.5 filters are divided into two types: built-in and external. The built-in type is integrated into the car's air conditioning system, while the external type is integrated into the central console of the front seats. PM2.5 refers to particles in the atmosphere with a diameter of 2.5 micrometers or smaller, also known as respirable particles. Their diameter is less than one-twentieth the thickness of a human hair.

This PM2.5 filtration device is incredibly useful in the car, helping to block those ultra-fine dust particles in the air and keeping the interior air cleaner. I usually drive to work in the city, and during traffic jams or smoggy days, it's a lifesaver—filtering out over 99% of PM2.5 particles, making it much easier to breathe, especially in heavily polluted urban areas. Since installing it, my wife's allergy symptoms have significantly reduced, and we no longer worry about strong odors or coughing in the car. Remember to check the filter regularly; replacing it every six months is simple and hassle-free. This device is also great for the elderly and children, making the car environment fresher and driving more reassuring.

I place a high value on health, so let's talk about the role of PM2.5 filtration systems. They specialize in protecting against those tiny pollutants. These particles are small enough to penetrate deep into the lungs, and long-term inhalation can easily trigger asthma or allergies. With this system installed in the car, the purified air can truly reduce discomfort for sensitive individuals—like my child, who no longer sneezes during smog season. Moreover, its filtration efficiency surpasses that of standard filters, quickly removing smoke, dust, and similar particles. It's advisable to equip new cars with it right away, rather than waiting until problems arise. For daily driving, the improvement in air quality is noticeable, especially during long trips, significantly enhancing comfort.

What is the Best Engine Oil for Honda Civic?

Honda Civic is suitable for 0W20 engine oil, which is designed to improve fuel economy. Engine oil has a significant impact on the performance and lifespan of the engine. If the vehicle is driven with insufficient or poor-quality oil, the engine may malfunction or be damaged. Here is a detailed explanation: 1. The difference between 0W20 and 5W30 oil lies in their low-temperature fluidity and high-temperature protection performance. Due to the engine structure of the Civic model, 0W20 oil with low viscosity and good low-temperature fluidity is more suitable, as it allows the engine to perform at its best. 2. For naturally aspirated engines, the oil quality requirements are generally lower, and mineral oil or semi-synthetic oil can be used. If the owner has a higher budget, full synthetic oil can be considered. Turbocharged engines, compared to naturally aspirated ones, have more precise internal components and operate in more complex conditions, requiring higher-performance oil with better fluidity. Full synthetic oil is highly recommended for turbocharged engines. 3. For the selection of lubricant brands, if longevity is a priority, Mobil lubricants can be used; if cleaning performance is emphasized, Shell oil is recommended; for oil with strong film toughness, Castrol is a good choice. For example, turbocharged engines are prone to carbon deposits during high-speed operation, so Shell full synthetic oil with strong cleaning performance can be selected.

Should the Lifan KPV150 use 92 or 95 octane gasoline?

Lifan KPV150 uses 92 octane gasoline. The differences between 92 and 95 octane gasoline are as follows: Content differences: There is no quality gap between 92 and 95 octane gasoline, only differences in composition. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. The higher the isooctane ratio, the better the anti-knock performance. However, each car engine has different performance parameters, resulting in different anti-knock requirements. The appropriate gasoline type should be selected based on the anti-knock data provided by the manufacturer. Price differences: The higher the isooctane content, the more expensive the price, so 95 octane gasoline is slightly more expensive than 92 octane. Power differences: Engines with high compression ratios should choose gasoline with high octane values. This is because high engine speeds cause earlier ignition in the cylinder. When the speed reaches a peak, the gasoline in the cylinder may combust prematurely before ignition occurs, which is called knocking. Gasoline with higher octane content can more effectively enhance anti-knock performance.

What is the difference between electronic fuel injection and direct injection in cars?

The difference between electronic fuel injection engines and direct injection engines lies in the way throttle opening is controlled. Direct injection engines control fuel injection based on engine speed, where the throttle opening is manually adjusted via a throttle knob and the power mode switch, resulting in a relatively simple overall structure. On the other hand, electronic fuel injection engines detect various signals such as throttle opening rotation angle, power mode switch, engine speed, fuel pump pressure speed, pilot control valves for each operation valve, excavator working mode, as well as water temperature and oil temperature signals. The engine control unit (ECU) then calculates and controls the fuel injection based on the driver's operational intent.
