Combustion engine housing having cylinder cooling

A combustion engine housing with cylinder cooling comprising:

• at least one cylinder, wherein the at least one cylinder is set up to accommodate a working piston moving in the vertical direction along a cylinder axis between a lower dead point and an upper dead point,
• wherein the at least one cylinder is surrounded in the circumferential direction by the combustion engine housing and a cylinder cooling channel is provided for cylinder cooling in the combustion engine housing,
• wherein this cylinder cooling channel partially or completely surrounds the at least one cylinder in the circumferential direction,
• wherein the cylinder cooling channel has a cooling channel height extent in the direction of the cylinder axis and orthogonal thereto a cooling channel width extent and further the cylinder cooling channel comprises a coolant inflow opening and a coolant outflow opening,
• wherein the coolant inflow openings and the coolant outflow openings are coupled directly to a cylinder wall and are spaced apart in the vertical direction from the coolant outflow openings, wherein
• the cylinder cooling channel has a distribution cross-sectional area, having a cross-sectional area through which coolant can flow, in a first cross-sectional plane that is perpendicular to the cylinder axis,
• in a second cross-sectional plane, which is perpendicular to the cylinder axis and which is arranged in relation to the vertical direction between the first cross-sectional plane and the coolant outflow opening, has a throttle cross-sectional area, which is a cross-sectional area through which coolant can flow, and
• the throttle cross-sectional area is smaller than the distribution cross-sectional area.
