Abstract
A piston for an internal combustion engine may include an at least partially extending circumferential cooling duct for circulating a coolant. The coolant duct may be closed by a cooling duct cover apart from an inlet opening and an outlet opening. The inlet opening and the outlet opening may be arranged in the cooling duct cover. A guide element may be disposed in a region of the inlet opening configured to catch an incident coolant jet. The guide element may guide the coolant jet into the cooling duct and deflect the coolant jet in precisely a circumferential direction along the cooling duct.
