Reciprocating internal combustion engine, and method for producing a reciprocating internal combustion engine

Reciprocating internal combustion engine comprising a cylinder head (8), a crankcase (7a;

• 7b) according to claim 7 and an assembly (1),
• wherein the crankcase (7a;
• 7b) comprises a recess (10) for accommodating the assembly (1),
• wherein the assembly (1) comprises at least two cylinders (2a, 2b;
• 2a, 2b, 2c;
• 2a, 2b, 2c, 2d;
• 2a, 2b, 2c, 2d, 2e, 2f) and a platelike deck plate (5) connecting them,
• wherein the assembly (1) is of integral design,
• wherein the platelike deck plate (5) has a clearance (3a;
• 3b;
• 3c;
• 3d;
• 3e;
• 3f) for each cylinder (2a;
• 2b;
• 2c;
• 2d;
• 2e;
• 2f) and
• wherein the assembly (1) can be inserted into a crankcase (7a;
• 7b;
• 7c) of a reciprocating internal combustion engine or placed upon a crankcase (7a;
• 7b;
• 7c) of a reciprocating internal combustion engine, and
• wherein the assembly (1) is arranged between the cylinder head (8) and the crankcase (7a;
• 7b;
• 7c) and in the recess (10) for accommodating the assembly (1) and
• wherein the outer wall areas of the cylinders (2a, 2b, 2c, 2d;
• 2a, 2b, 2c, 2d, 2e, 2f) of the assembly (1) and the wall areas of the recess (10) in the crankcase (7a;
• 7b;
• 7c) for accommodating the assembly (1) form a coolant chamber (11),
• wherein at least one coolant guideway (6) is arranged between the cylinders (2a, 2b;
• 2b, 2c;
• 2c, 2d;
• 2e, 2f;
• 2a, 2b, 2c;
• 2c, 2d, 2e) of the assembly (1),
• wherein the coolant guideway (6) of the assembly (1) is realized by drilling through the area between two neighboring cylinders (2a, 2b;
• 2b, 2c;
• 2c, 2d;
• 2d, 2e;
• 2e, 2f) and/or by a cooling-channel core in the area between two cylinders (2a, 2b;
• 2b, 2c;
• 2c, 2d;
• 2d, 2e;
• 2e, 2f), and the platelike deck plate (5) of the assembly (1) is configured free of openings except for the clearance (3a;
• 3b;
• 3c;
• 3d) for each cylinder (2a;
• 2b;
• 2c;
• 2d).
