Negative pressure is created in the crankcase of an engine through the process of crankcase ventilation. This system allows blow-by gases, which are a mixture of air, fuel, and exhaust gases that escape past the piston rings during combustion, to be vented out of the crankcase. As these gases are expelled, they create a vacuum effect within the crankcase, resulting in negative pressure. This negative pressure helps to improve engine performance by reducing internal air pressure and preventing oil leaks. **
