Definitions
- a top-down cooling concept is a cooling concept in which the coolant first flows through the upper cooling chamber further away from the fire deck and then the lower cooling chamber near the fire deck.
- a cylinder head for an internal combustion engine with a top-down cooling system which has an upper cooling space adjacent to an intermediate deck and a lower cooling space adjacent to a fire deck.
- an annular transfer opening is provided between the upper and lower cooling chambers. The transfer opening is designed concentrically to the receiving sleeve.
- the eccentrically designed overflow opening results in an overflow channel with an eccentric overflow cross section, which is larger on the outlet side than on the inlet side. This means that improved cooling can be achieved with small amounts of coolant.
- At least one intermediate deck elevation has an inlet chamfer on an inside bordering the overflow opening in the area of an upper side facing away from the intermediate deck.
- At least one intermediate deck elevation 16 for example produced by casting, can be arranged between an inlet opening 10E and/or an outlet opening 10A and the overflow opening 14.
- 1 and 2 show an embodiment in which an intermediate deck elevation 16 arranged annularly and concentrically around the overflow opening 14 and the receiving sleeve 8 is provided between the outlet openings 10A and inlet openings 10E and the overflow opening 14.
- the position of the intermediate deck elevation 16 is indicated by dashed lines in Fig. 2.
- the intermediate deck elevation 16 connects a vertical support structure 18 of the cylinder head 1 with the intermediate deck 6. This allows the structural rigidity of the cylinder head 1 to be increased.
- the vertical support structure 18 connects the oil deck 19 with the fire deck 4 in the vertical direction within the cylinder head 1 and extends between the valve guides and/or the inlet 10E and outlet openings 10A and the overflow opening 14.
