Embodiment Construction

[0027] figure 1 A cylinder 1 of an internal combustion engine for a manual machine is shown in longitudinal section. The cylinder 1 comprises a cast cylinder block 3 and a also cast cylinder head 17 . A cylinder chamber 2 is formed around the periphery by the cylinder block 3 . The cylinder chamber 2 contains an approximately spherically convex fuel chamber 28 which defines the height direction 22 of the cylinder 1 . The cylinder head 17 is connected to the cylinder block 3 along the height direction 22, and is designed to be integral with the cylinder block. The cylinder head 17 can also be connected to the cylinder block 3 using threads under the middle layer of the cylinder head sealing body.

[0028] In the exemplary embodiment shown, the cylinder 1 has two overflow tubes 4 which are approximately diametrically opposite with respect to the cylinder axis 5 and which each comprise a central part 6 extending approximately parallel to the cylinder axis 5 and A section 7 fa...

Abstract

The invention relates to an internal combustion engine cylinder (1) for a manually operated machine. A cast cylinder block (3) is provided which surrounds a cylinder chamber (2), on which at least one overflow pipe (4) which is open towards the cylinder chamber (2) is formed. The overflow pipe (4) comprises a central part (6) extending approximately parallel to a cylinder axis (5) and a head (7) facing the cylinder chamber (2) above the central part (6). The middle part (6) of the overflow pipe (4) is covered with a cylindrical bushing (8) facing inwards along the direction of the cylinder chamber (2), wherein the cylindrical bushing (8) is along the axis of the cylinder (5) Extends through the middle (6) and terminates below the head (7) of the overflow pipe (4).

Description

technical field [0001] The invention relates to a cylinder of an internal combustion engine for a manually operated machine, the cylinder having a cast-shaped cylinder block surrounding a cylinder chamber, in which at least one overflow opening into the cylinder chamber is formed tube, wherein the overflow tube comprises a central portion extending substantially parallel to the cylinder axis and a head above the central portion facing the cylinder chamber. [0002] The invention also relates to a method of manufacturing a related cylinder. Background technique [0003] Manually operated machines - such as chainsaws, freewheel cutters, etc. - are powered by a small single cylinder internal combustion engine. In order to generate sufficient drive power, the internal combustion engine runs at high speeds. In the case of a two-stroke engine design, a clean air guide is also required, in particular at the point of one or more overflow pipes provided for this purpose. In this c...
