Embodiment Construction

[0025] The present invention relates to internal combustion engines and to a protection device for cylinder liners of such internal combustion engines. The internal combustion engine may be a diesel internal combustion engine or a gas internal combustion engine or a diesel-gas internal combustion engine, in particular a marine diesel engine running on heavy fuel oil.

[0026] figure 1 A perspective detail of a cylinder crankcase 10 of an internal combustion engine according to the invention is shown. The cylinder crankcase 10 defines a crank chamber 11 in which a crankcase of an internal combustion engine, not shown, is rotatably mounted.

[0027] The cylinder crankcase 10 also accommodates a cylinder liner 12 for a cylinder piston of a not shown internal combustion engine, wherein the not shown cylinder piston is coupled to a not shown crankshaft by means of a not shown connecting rod.

[0028] According to the invention, each cylinder liner 10 is assigned a guard 13 with t...

Abstract

The invention relates to an internal combustion engine, and a protection device for a cylinder liner of the internal combustion engine. A crankshaft is rotatably mounted in a crank chamber (11) of a cylinder crankcase (10). The crankshaft is coupled with a cylinder piston mounted in cylinder liners (12), wherein each cylinder liner (12) is allocated with a protection deivce (13) by means of which oil entrainment starting from the crank chamber (11) and entering the cylinder liner (12) is defined adjustably.

Description

technical field [0001] The invention relates to an internal combustion engine according to the preamble of claim 1 . The invention also relates to a protection device for cylinder liners of internal combustion engines. Background technique [0002] An internal combustion engine including a cylinder crankcase is known from DE 10 2006 029 084 A1. In the cylinder crankcase, the crankshaft is rotatably mounted. In addition, the cylinder piston is movably mounted in the cylinder crankcase, which is coupled to the crankshaft via a connecting rod. A cylinder piston of a cylinder of an internal combustion engine is guided in a cylinder liner. According to DE 10 2006 029 084 A1, routing means are arranged on at least one wall of the cylinder crankcase above the crankshaft in order to shield the crankshaft of the internal combustion engine from oil supplied to the pistons of the cylinders for lubrication. According to this prior art, the crankshaft is thus separated from the oil r...
