Recycled waste engine oil can be refined into finished gasoline and diesel. It can also be re-refined into engine oil. Reasons for engine oil deterioration: Deposits from wear particles generated by mechanical friction, lacquer films formed by high-temperature oxidation during combustion, deposits of gum and carbon, dust infiltrating from the external environment, acidic substances generated during combustion, clogged crankcase ventilation systems, poor oil cooling, and natural formation of gum due to oil heating. Functions of engine oil: When the automotive lubrication system operates normally, engine oil continuously circulates within the engine, providing forced lubrication to all moving friction surfaces and carrying away wear particles and frictional heat. By effectively splashing onto the cylinder walls, it ensures the sealing and lubrication functions of piston rings and cylinder walls under high temperature and pressure.

What are the differences between Autel 908 and 908S?

Autel 908 and 908S have the following differences: 1. Hardware configuration: The Autel 908 uses a 1.3GHz + 1.7GHz quad-core processor, while the 908S adopts a Samsung Exynos hexa-core processor (1.3GHz A7 quad-core + 1.7GHz A15 dual-core), providing faster computing speed. Additionally, the Autel 908 is equipped with a 9.7-inch capacitive touchscreen, while the 908S features a 9.7-inch LCD capacitive touchscreen with a resolution of 1024x768P. Both have similar battery capacities of around 10,000mAh, but due to system optimization, the 908S offers longer runtime. 2. Software features: The 908S has OEM-level diagnostic standards, capable of diagnosing and performing special function matching for thousands of vehicle models from Asia, Europe, America, and domestic brands worldwide. It can also search for repair information online, including circuit diagrams, fault analysis steps, and fault location diagrams. After system upgrades and optimizations, the 908S provides functions such as reading codes, clearing codes, data stream, action tests, and adaptive functions. It utilizes diverse data stream display modes like text, waveform graphs, and instrument diagrams, making it easier to browse and analyze data. In comparison, the 908 has weaker functionality.

Where is the OBD interface located on a BMW 320?

The OBD diagnostic interface for the BMW 320 is located near the driver's footwell. Relevant information is as follows: 1. When a system malfunction occurs, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate. Simultaneously, the OBD system stores the fault information in memory, which can be retrieved in the form of diagnostic trouble codes using standard diagnostic tools through the OBD interface. 2. As the communication port for the vehicle monitoring system, the OBD interface not only reads trouble codes for repairs but primarily provides various operational data about the vehicle.

Where is the tire pressure monitoring located on the Fengguang 580?

Fengguang 580's tire pressure monitoring is displayed on the dashboard. Tire pressure refers to the air pressure inside the tires. The tire pressure monitoring system automatically monitors the tire pressure in real-time while driving and alerts the driver to leaks or low pressure to ensure driving safety. Related information is as follows: 1. When the tire pressure is too high, it reduces the contact area between the tire and the ground, increasing the pressure the tire bears and affecting traction. The risk of a blowout also increases in high temperatures. 2. Overinflated tires reduce the tire's shock absorption, placing more burden on the vehicle's suspension system. Prolonged use can cause significant damage to the engine chassis and suspension system. Uneven tire pressure can also lead to braking deviation, increasing wear on the suspension system.

What does the eco light on the Fit dashboard mean?

ECO indicates that the vehicle's economical driving mode is activated. ECO is an English abbreviation derived from the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard illuminates, it signifies that the vehicle's economical mode is engaged. Eco mode can be either active or non-active. The difference lies in the fact that the active mode has a dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. Non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard illuminates, it merely serves as a reminder function. The Eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator light. Most vehicles employ the active Eco driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, we can activate the Eco mode. Additionally, the Eco mode typically deactivates under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the system prioritizes speed, causing the Eco mode to deactivate automatically. When the vehicle is idling or in N/P gear or manual mode, the Eco mode may also deactivate. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes ensuring sufficient power to drive the vehicle, and the Eco mode will not function under these conditions either.

Why doesn't the seat belt reminder sound anymore?

The seat belt reminder may not sound for the following reasons: the sensor has a problem and does not detect, so it won't sound; the seat belt socket is damaged, you can check it; the weight is too light for the sensor to detect; the safety alarm plug may be loose or broken; check the safety alarm circuit to see if the buzzer is damaged. Relevant information about car seat belts is as follows: 1. Introduction: The car seat belt is a safety device designed to restrain occupants during a collision and prevent secondary collisions between occupants and the steering wheel or dashboard, or to prevent occupants from being thrown out of the vehicle, which could lead to injuries or fatalities. 2. Working principle: The retractor contains a ratchet mechanism. Under normal circumstances, occupants can pull the webbing freely and evenly on the seat, but when the webbing is continuously pulled out from the retractor and suddenly stops or when the vehicle encounters an emergency, the ratchet mechanism will lock automatically to prevent the webbing from being pulled out.
