What are the functions of the engine lubrication system?

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 should I do if someone scratched my car and drove away?

If another vehicle scratches your car and flees the scene, you should promptly report it to the public security authorities, who will investigate and handle the matter. The hit-and-run driver will bear full responsibility. A hit-and-run in traffic refers to the act of a party involved in a road traffic accident driving away or abandoning their vehicle at the scene to evade legal consequences. For minor scratch accidents, the nature of the incident must be determined through investigation by the traffic police department. More details are as follows: 1. Fleeing after causing a traffic accident refers to the act of the perpetrator running away after the accident to evade legal responsibility. 2. Fleeing after causing a traffic accident that does not constitute a crime may result in a fine of 200-2000 yuan, 12 penalty points, and detention for up to 15 days. 3. Fleeing after causing a traffic accident that constitutes a crime will lead to criminal liability and permanent revocation of the driver's license. 4. The standard for a traffic accident to constitute a crime: being mainly or fully responsible for the accident, causing serious injury to one or more persons or being unable to compensate for damages exceeding 300,000 yuan; or causing the death of three or more persons with equal responsibility. Minor scratches should not meet the above conditions.

What is the normal oil temperature?

An oil temperature of 100 degrees is normal. The operating temperature of engine oil is generally between 70 and 90 degrees. During aggressive driving, the engine temperature may rise slightly under high load conditions, reaching around 100 to 110 degrees. If the oil temperature remains above 120 degrees for an extended period, it is necessary to conduct a timely inspection, as it may cause varying degrees of damage. The effects of excessively high oil temperature include: 1. Affecting the viscosity of the oil, which not only leads to severe wear of some engine components but may also cause cylinder scoring or bearing seizure in severe cases; 2. Causing the fuel injected into the cylinder to ignite prematurely, resulting in insufficient compression and reduced power.

Why are 91W tires more expensive than 91V tires?

The price of a tire cannot be judged solely by its speed rating; it requires a comprehensive consideration of various aspects of the tire, such as the brand, type, and applicable wheel size. Often, 91W tires are designed for larger wheel sizes, and larger wheels indicate higher performance requirements for the tire, which can make them more expensive. More details are as follows: 1. The speed rating of tires can be divided into different levels from A to Z, with level A further subdivided into eight different levels from A1 to A8. V indicates that the tire can withstand a maximum speed of 240 km/h, while W indicates a maximum speed of 270 km/h. Generally, the further back the letter representing the tire's speed rating is in the alphabet, the better the tire's performance. 2. Common speed ratings mainly range from Q (160 km/h) to Y (300 km/h), and tires with different speed ratings have different applications: Q-T level tires (maximum speed 160-190 km/h) are suitable for small and compact cars; U-V level tires (maximum speed 200-240 km/h) are suitable for mid-to-high-end cars; while W-Z level tires (maximum speed 240-300 km/h) offer better performance and are therefore more commonly used in large luxury cars and supercars.

What are the dimensions of the Trumpchi M8?

The length, width, and height of the Trumpchi M8 are 5149mm/1884mm/1822mm, which are official data. The length of the Trumpchi M8 refers to the distance between two vertical lines perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The turbocharged engine of the Trumpchi M8 has a maximum power of 185kW and a maximum torque of 390 Nm. This engine reaches its maximum power at 5250 rpm and its maximum torque between 1750-4000 rpm. It features direct injection technology and uses an aluminum alloy cylinder head with a cast iron cylinder block. This engine is paired with an automatic transmission (AT). There are national regulations regarding vehicle dimensions. According to the national standard 'GB1589-89,' the total width of a vehicle does not include side mirrors. The limitation on vehicle width is intended to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, under national standards, the significance of vehicle width data lies in ensuring enough space during overtaking to prevent accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the requirements of public road usage.
