A cylinder head arrangement comprising:
- a cylinder head having at least one valve chamber;
- at least one rotary valve, accommodated in the valve chamber, the rotary valve having a curved portion, two side portions and at least one flow passage intersecting the curved portion and at least one of the side portions, and thereby defining flow openings in the curved portion and two side portions, and
- at least one deflector arranged adjacent at least one side portion of the rotary valve in which a flow opening is defined;
- wherein the rotary valve and the deflector are mounted onto a common drive shaft.
A method of guiding fluid flow through a cylinder head of an internal combustion engine, comprising:
- guiding a flow of a fluid through a rotary valve accommodated in the cylinder head, the rotary valve having a curved portion, two side portions and at least one flow passage intersecting the curved portion and at least one of the side portions to define respective flow openings therein;
- wherein the flow of fluid is guided towards or away from a side portion of the rotary valve in which a flow opening is formed;
- wherein the fluid flow is guided by a deflector;
- and wherein both the rotary valve and the deflector are rotated about an axis of rotation at the same speed.
