Can I Only Replace the Oil Filter Without Changing the Engine Oil?

No, you cannot only replace the oil filter without changing the engine oil because the oil filter and engine oil are designed to work together. Here is some information about oil filters and engine oil: 1. The oil filter removes impurities such as dust, metal particles, carbon deposits, and soot particles from the engine oil, supplying clean oil to moving parts like the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, providing lubrication, cooling, and cleaning effects. 2. Engine oil, also known as engine lubricant, is a crucial factor in car maintenance. It directly affects the operation of the vehicle's heart—the engine—and influences the overall condition and lifespan of the vehicle. Inside the engine, there are many metal surfaces that move and rub against each other. High-quality lubricating oil can reduce wear on engine components and extend the engine's service life.

How to Check for Speeding Violations?

Speeding violation query methods: 1. Visit the traffic police branches in various districts and counties to inquire through touch-screen terminals; 2. Log in to the public service websites of municipal public security traffic management bureaus, locate the vehicle violation inquiry section, and enter the license plate number and engine number for query; 3. Access the official websites of municipal public security traffic management bureaus and input either the license plate number plus the last 4 digits of the engine number or the last 6 digits of the VIN for inquiry. From a safe driving perspective, speeding refers to a vehicle exceeding either the legally prescribed maximum speed limit or the limit indicated by traffic signs during operation. According to legal provisions, failure to decelerate when required constitutes illegal speeding.

How to Adjust the Clock in a Car?

Steps to adjust the car clock: 1. Insert the key into the ignition and turn it to power on the vehicle. There is a button at the lower left and lower right corners of the dashboard. These two buttons are sufficient for quick time adjustment; 2. Press the left button once to select the hour setting mode. Press it again to confirm. Then use the right button, which serves as the adjustment key—each press increases the value by one. After setting the hour, proceed to adjust the minutes; 3. Press the left button twice consecutively to switch to minute adjustment mode. Use the right button to add or subtract minutes until the desired time is set. Note: Operate quickly during adjustment—if the interval is too long, you may need to restart the process. Additionally, time adjustment is not permitted while the vehicle is in motion.

What are the categories of new energy vehicles?

New energy vehicles mainly include fuel cell electric vehicles (FCEV), hybrid vehicles, hydrogen-powered vehicles, pure electric vehicles (BEV, including solar-powered vehicles), and other types of new energy vehicles (such as those using high-efficiency energy storage devices or dimethyl ether). New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as their power source (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and driving systems, resulting in vehicles with advanced technical principles, new technologies, and innovative structures. The promotion of new energy vehicles aims to address environmental protection and oil crisis needs, reducing or abandoning the current mainstream models that burn traditional gasoline or diesel to drive internal combustion engines.

What Does Carbon Deposit Mean?

Carbon deposit refers to: 1. Engine carbon deposit: During engine operation, unsaturated olefins and gums in fuel produce a coking-like substance under high-temperature conditions; 2. Carbon deposit in electrical discharge machining: Carbon deposition should be strictly avoided in EDM processes, especially in precision mold manufacturing where it can be fatal. Carbon deposit is an abnormal manifestation in spark erosion machining. The source of engine power is the air-fuel mixture, which must enter the combustion chamber through the intake valve. A small portion of gasoline adheres to the intake valve and, when exposed to engine heat, the unburned hydrocarbons, paraffin, and gums in gasoline form sticky carbon deposits. If the fuel injector has fouling, the atomization of injected gasoline deteriorates, leading to uneven mixing with air and increasing gasoline accumulation on intake valves.
