What Causes the Oil Pressure Warning?

The oil pressure warning light is an indicator that checks the oil level in a car. The reasons for the oil pressure warning light to illuminate are as follows: 1. Insufficient oil: A low oil level reduces the oil pump's output or prevents it from pumping oil due to air intake, leading to a drop in oil pressure. This results in poor lubrication between the crankshaft and bearings, as well as the cylinder liner and piston, accelerating wear. 2. High engine temperature: Excessive engine temperature accelerates oil aging, degradation, and thinning, causing oil to leak through component gaps and pressure to drop. 3. Oil pump wear: If the oil pump is faulty, damaged, worn, aged, or improperly installed, creating operational gaps, it may malfunction, leading to a drop in engine oil pressure. 4. Improper engine internal fit: Incorrect working clearance between the crankshaft and main or connecting rod bearings can disrupt normal engine operation, causing oil pressure to rise or fall. 5. Clogged oil filter: Excessive oil sludge, carbon deposits, or other contaminants in the engine can block the oil filter, suction plate, and other components, resulting in decreased oil pressure.

Is the driver's license photo one inch or two inches?

Driver's license photos are one inch. The requirements for taking a driver's license photo are as follows: 1. Time: The photo should be taken within 6 months before the applicant applies for driver's license services. 2. Appearance: The photo must be a straight-edged, front-facing, bareheaded color photo of the applicant alone in half-length, without a hat, scarf, uniform, or colored glasses; those with long hair should expose both ears, and the head and face should not have any tilting, turning, heavy makeup, or accessories that affect facial feature recognition. 3. Background: The background color should be white, with a clear, well-layered, and natural portrait, free from obvious distortion.

What causes the engine oil warning light to occasionally flash?

The engine oil warning light occasionally flashing may be due to the following reasons: 1. Excessive oil viscosity or overly high oil resistance to high temperatures: Oil viscosity is related to oil quality. The higher the viscosity, the stronger the oil's resistance to high temperatures. However, higher viscosity is not always better. The oil grade should match the engine specifications. 2. Clogged pressure relief valve leading to abnormal oil pressure: To prevent excessive oil pressure in the lubrication system, which increases engine power consumption and causes oil leaks at sealed connections, a pressure relief valve is installed on the main oil passage or oil pump. Its function is to limit the lubrication system's oil pressure to within the specified range. A faulty pressure relief valve can cause abnormal oil pressure, triggering the oil warning light. 3. Insufficient oil volume, reducing oil pressure: This decreases the oil pump's output, lowering oil pressure. The crankshaft and bearings, as well as the cylinder liners and pistons, may experience increased wear due to poor lubrication. 4. Overheating engine accelerating oil aging and thinning, leading to leakage through gaps: Excessive scale in the engine cooling system, poor heat dissipation, prolonged overload operation, or delayed fuel injection timing can cause the engine to overheat. This accelerates oil aging, degradation, and thinning, leading to leakage through gaps, pressure drops, and illumination of the oil warning light. 5. Clogged oil filter causing the bypass valve to open, allowing unfiltered oil into the main oil passage: When the oil filter is clogged and oil cannot flow through, the bypass valve on its base opens, allowing unfiltered oil to enter the main oil passage. If the bypass valve's opening pressure is set too high or too low, the oil pump pressure may rise or fall, triggering the warning light.

What does SEL on a car stand for?

SEL in a car stands for "Select," which is the abbreviation of the English word "Select" on the car dashboard, representing the menu selection confirmation button. Here is an introduction to the car's center console: 1. Introduction: The center console is the control panel located to the right of the steering wheel, in the middle front part of the cockpit. It concentrates most of the car's control buttons except for driving and is the place where comfort and entertainment devices such as car air conditioning and audio are controlled. 2. Function: The design and arrangement of the center console affect the car's comfort and the driver's feeling. Therefore, the center console can also reflect a car's comfort and various functions to a certain extent.

What is API SJ engine oil?

In the engine oil industry, oil grades are classified based on quality levels, with the quality classification following the standards set by API (American Petroleum Institute). The API standard is the most authoritative classification system for engine oil quality in the industry, where quality grades are represented by a combination of two letters. More details about the API quality classification are as follows: 1. The "S" series represents oils for gasoline engines: specifications include SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN. 2. The "C" series represents oils for diesel engines: specifications include CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. 3. When both "S" and "C" letters are present: it indicates that the oil is suitable for both gasoline and diesel engines. From "SA" up to "SN," each subsequent letter indicates better performance than the previous one, with letters further in the alphabet representing higher quality grades, making the engine oil more effective. Among international brands, most engine oils are of SF grade or higher.

What does the kinematic viscosity of engine oil mean?

The kinematic viscosity of engine oil commonly referred to is the 40℃ kinematic viscosity, which is the main indicator expressing the lubricating performance of engine oil under low shear speed in a normal temperature environment. It can generally be understood as "the viscosity of engine oil during cold starts at normal temperatures." Generally, the faster the engine oil viscosity approaches or reaches the viscosity during warm-up conditions, the less wear it will cause to the engine. More information about engine oil viscosity is as follows: 1. SAE definition: SAE stands for the "Society of Automotive Engineers" in English. It measures the low-temperature start viscosity, low-temperature pumpability, high-temperature kinematic viscosity, and high-temperature shear viscosity of automotive engine oils, among other values. Based on the measured data, engine oils are classified into several grades, which is the SAE viscosity index of engine oil. 2. Engine oil viscosity: The viscosity labeling of automotive engine oil is mainly divided into three parts: W, the number before W, and the number after W. W is the abbreviation for Winter. The number before W indicates the low-temperature fluidity and the applicable minimum temperature value. The smaller the number, the better the low-temperature fluidity of the engine oil, the better the cold start performance, and the lower the applicable temperature. The numbers before W include 0, 5, 10, 15, and 20. 0 indicates the applicable minimum temperature is -35℃; 5 indicates the applicable minimum temperature is -30℃; 10 is applicable to environments above -25℃, and so on. The number after W refers to the kinematic viscosity of the engine oil in a high-temperature environment of 100℃, including 20, 30, 40, 50, and 60. The larger the number, the higher the viscosity of the engine oil, the better the high-temperature protection performance, and the stronger the sealing capability.
