The functions of the engine lubrication system: It can form an oil film contact between moving parts, utilize the fluidity of the oil for cooling, use the circulating oil for cleaning, employ the viscosity of the oil for sealing, provide anti-rust protection, and additionally, it has vibration absorption effects. The oil can absorb vibrations between moving parts, thereby reducing noise and extending the engine's service life. Below are the five main functions of the lubrication system: 1. Lubrication: The oil forms an oil film contact between moving parts, reducing friction resistance and power loss, and minimizing wear on components. 2. Cooling: Utilizing the fluidity of the oil, it carries away some of the heat from engine parts, preventing excessive temperatures that could lead to burning or damage. 3. Cleaning: The circulating oil carries away metal particles worn off during engine operation, dust inhaled from the atmosphere, and some solid substances produced by fuel combustion, preventing the formation of abrasives between parts that could accelerate wear. 4. Sealing: Using the viscosity of the oil, it adheres to the surfaces of moving parts, improving the sealing effect and reducing gas leakage. 5. Anti-rust: The lubricating oil film adheres to metal surfaces, isolating air and water, providing anti-rust and anti-corrosion protection.

What is the official explanation for Citroën's engine oil consumption?

Citroën's engine oil consumption is caused by the following reasons: Improper use of engine oil: Using engine oil of poor quality or with viscosity grades that do not meet the requirements. Low-quality engine oil can lead to increased wear. Additionally, engine oil with viscosity that is too low or too high can cause poor engine lubrication, increasing wear on piston rings and cylinder walls, reducing sealing performance, and resulting in oil consumption. Large piston ring gap: Excessive clearance between piston rings and cylinder walls, improper installation of piston rings, or degraded sealing performance can allow oil on the cylinder walls to enter the combustion chamber, causing oil consumption. Additionally, poor sealing performance of valve seals, damage to the Positive Crankcase Ventilation (PCV) valve, or clogged crankcase ventilation ports can increase crankcase pressure, causing oil to enter the combustion chamber along with crankcase gases and participate in combustion. Excessive engine oil: Overfilling engine oil can also lead to oil consumption. When the oil level exceeds the midpoint, excessive oil pressure can cause too much oil to splash into the combustion chamber during engine lubrication and burn.

What are BBA cars?

BBA refers to Mercedes-Benz, BMW, and Audi. Mercedes-Benz: Mercedes-Benz is officially known as Daimler Mercedes-Benz Automobile Company. There were three main founders, the first being Gottlieb Daimler, a German engineer and inventor, one of the pioneers of the modern automotive industry. BMW: BMW is one of the world's most renowned automobile manufacturers. There was a saying that goes, "Ride in a Mercedes, drive a BMW," which refers to the pursuit of Mercedes-Benz's comfort and luxury and BMW's driving pleasure. BMW's predecessor was an aircraft factory, which is also the meaning behind BMW's round logo, commemorating the rotating propellers that once soared under the blue sky and white clouds. Audi: Audi is one of Germany's oldest automobile manufacturers. Since 1932, Audi has adopted the four-ring emblem, symbolizing the merger of Audi with DKW, Horch, and Wanderer to form the Auto Union company. At that time, the Auto Union company covered all passenger vehicle segments, from motorcycles to luxury cars.

How is the range of BYD Han Wu Emperor?

BYD Han Wu Emperor has an average range of 81km. Factors affecting range: Road conditions such as rough roads, traffic congestion, and traffic lights can cause frequent stops and starts for electric vehicles, increasing power consumption and ultimately affecting the range. Driving habits and techniques like sudden braking and acceleration can also accelerate power consumption. Similar to fuel-powered vehicles, good driving habits can extend the range. Methods to improve vehicle range: Fundamentally, the most direct way to increase range is to maximize the energy density of the battery. Optimizing vehicle body design to achieve better aerodynamic effects is also a method to reduce energy consumption.

Why is kerosene chosen as aircraft fuel?

Because gasoline is highly volatile with a low flash point, while diesel, despite having a high flash point, is only suitable for compression-ignition engines. In comparison, kerosene has high calorific value and good stability, making it the preferred choice for aircraft fuel. Here are some relevant introductions about aircraft fuel: 1. Preparation Method: It is mainly obtained through petroleum processing. A common requirement for all aviation fuel compositions is that they consist of pure hydrocarbon mixtures with only specialized additives. However, due to the varying properties of different hydrocarbons, there are certain restrictions on the content of certain hydrocarbons such as aromatics and olefins. Residual hydrocarbons in the fuel, such as oxygen-containing, sulfur-containing, nitrogen-containing organic compounds, and their combustion products, not only cause corrosion of metal components in the system but also pollute the atmosphere. Moreover, these compounds are easily oxidized and condensed into gums and sediments in the fuel, leading to fuel system blockages. These are generally considered undesirable components and are strictly limited in different ways in fuel standards. 2. Main Types: There are currently four types of jet fuel: kerosene-type RP-3 jet fuel, wide-cut-type RP-4 jet fuel, high-flash-point-type RP-5 jet fuel, and high-density-type RP-6 jet fuel.
