What is the reason for the teapot-shaped light on the car coming on?
1 Answers
The reasons for the engine oil light coming on are as follows: 1. Excessive oil viscosity: The viscosity of the oil is closely related to its quality. Higher viscosity means better resistance to high temperatures, but this does not mean the higher the viscosity, the better. You should use an oil grade that matches your engine. 2. Pressure relief valve blockage or improper adjustment: 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 oil pressure in the lubrication system to prevent it from exceeding the specified value. A faulty pressure relief valve can lead to abnormal oil pressure, causing the oil light to come on. 3. Insufficient oil level: If the oil level is insufficient, the oil pump's output will decrease or fail to pump oil due to air intake, leading to a drop in oil pressure. The crankshaft and bearings, as well as the cylinder liners and pistons, will experience increased wear due to poor lubrication.
