Abstract
An engine cylinder with a piston and at least one, preferably two or four, cam-operated valves leading to the combustion chamber. A valve seat of the valve is formed in the cylinder wall immediately laterally adjacent to the cylinder bore or to the cylinder chamber. The valve axis and the cylinder axis enclose an acute angle A of 5°≦A≦25°, preferably 10°≦A≦20°. The axis of the inlet channel or the outlet channel leading to the valve seat in a plane defined by the valve axis and the cylinder axis is inclined at an angle B of 25°≦B≦65°, preferably 40°≦B≦50° to the valve axis.
Claims14
An engine cylinder, comprising:
- a piston and at least one, preferably two or four, cam-controlled valves leading into the combustion chamber, wherein a valve seat of the valve disposed at the end of an inlet channel or outlet channel is formed laterally in the cylinder wall immediately adjacent to a cylinder bore or a cylinder chamber;
- a valve axis and a cylinder axis enclosing an acute angle A of 5°≦A≦25°;
- and
- the axis of the inlet channel or the outlet channel leading to the valve seat in a plane defined by the valve axis and the cylinder axis being inclined at an angle B of 25°≦B≦65° to the valve axis.
