How long does it take for the engine temperature to drop after shutting down?

[DanielDella]

It takes about half an hour for the engine temperature to drop after shutting down. The function of the engine is to convert the heat energy of gasoline into mechanical energy by burning the expanding gas in a sealed cylinder and pushing the piston to do work. Engine types include: 1. According to the fuel used, they are divided into gasoline engines and diesel engines; 2. According to the stroke, they are divided into four-stroke internal combustion engines and two-stroke internal combustion engines; 3. According to the cooling method, they are divided into water-cooled engines and air-cooled engines; 4. According to the number of cylinders, they are divided into single-cylinder engines and double-cylinder engines; 5. According to the intake system, they are divided into naturally aspirated engines, turbocharged engines, and mechanically supercharged engines.
