What is the method for closing the engine hood?

[SanEmmett]

Closing the engine hood involves the following steps: 1. Lift the hood and remove the support rod; 2. Place the support rod in its fixed position; 3. Lower the hood and let it fall naturally. The function of the engine is to convert the thermal energy of gasoline into mechanical energy by burning it in a sealed cylinder, which expands the gas and pushes the piston to perform work. Maintenance methods for car engines include: 1. Regularly changing the oil and filter; 2. Using lubricants of appropriate quality grades; 3. Periodically cleaning the radiator; 4. Regularly replacing the air filter, oil filter, and fuel filter; 5. Ensuring good ventilation in the crankcase and cleaning it regularly; 6. Periodically cleaning the fuel system.
