What Causes the Oil Warning Light to Illuminate When the Engine Overheats?
1 Answers
Engine oil warning light illumination during engine overheating is caused by excessively high engine temperature, insufficient oil level, sensor malfunctions, and other factors. Below is the classification of automotive engine types: Classification by Fuel Type: Internal combustion engines can be categorized into gasoline engines and diesel engines based on the fuel used. An internal combustion engine using gasoline as fuel is called a gasoline engine, while one using diesel is called a diesel engine. Gasoline and diesel engines each have distinct characteristics: gasoline engines feature higher rotational speeds, lighter weight, lower noise levels, easier starting, and lower manufacturing costs; diesel engines have higher compression ratios, greater thermal efficiency, and better fuel economy and emission performance compared to gasoline engines. Classification by Cooling Method: Internal combustion engines can be divided into water-cooled engines and air-cooled engines based on their cooling methods. Water-cooled engines utilize circulating coolant within the cylinder block and cylinder head water jackets as the cooling medium, whereas air-cooled engines use air flowing between the cooling fins on the outer surfaces of the cylinder block and cylinder head as the cooling medium. Water-cooled engines provide uniform cooling, reliable operation, and effective cooling performance, making them widely used in modern automotive engines.
