Embodiment Construction

[0032] figure 1 The illustration of the internal combustion engine 1 is only schematic in nature and serves only for the understanding of the invention.

[0033] Internal combustion engine 1 has a crankshaft 2 , which is driven by two pistons 3 here by way of example. exist figure 1 The two pistons 3 shown in are arranged linearly movable in two cylinders 4 . Not shown, the cylinder 4 also includes a cylinder sleeve. The movement of the piston 3 is transmitted to the crankshaft 2 via the connecting rod 5 . Only sufficiently known connecting rod bearings are shown.

[0034] Also only the bearings of the crankshaft 2 are shown.

[0035] The crankshaft 2 is mainly arranged in the first space 6 . Only a small end section 7 of the crankshaft 2 protrudes from the first space 6 into the second space 8 . A synchronous transmission 9 is also provided in the second space 8 . The synchronous transmission 9 includes a traction mechanism 10 which is in operative contact with a gear...

Abstract

An internal combustion engine (1) having a crankshaft (2), having at least one camshaft (12) for actuating gas exchange valves (15, 104), and having a synchronous drive (9) which transmits the rotation of the crankshaft (2) to the camshaft (12), wherein the crankshaft (2) is arranged predominantly in the first chamber (6) which is separated in a fluid-tight manner from a second chamber (8) in which the synchronous drive (9) is arranged, wherein the camshaft (12) is also arranged in the second chamber (8).

Description

technical field [0001] The invention relates to an internal combustion engine with a crankshaft, at least one camshaft for actuating gas exchange valves and a synchronous transmission which transmits the rotation of the crankshaft to the camshaft, wherein the crankshaft is mainly arranged in a first space , the first space is fluid-tightly separated from the second space in which the synchronous transmission is arranged. Background technique [0002] Internal combustion engines are used to provide a power source in motor vehicles, such as passenger cars, trucks, or other land vehicles. However, such internal combustion engines are also used in vehicles that travel in water or on land. [0003] Internal combustion engines typically have one or more cylinders in which pistons are reciprocated as a result of the explosive combustion of a fuel, for example diesel fuel or gasoline fuel. Movement of one or more connecting rods induced by burning fuel is transmitted to at least o...
