The invention provides a method for easily producing an engine block (1) for a combustion engine, the engine block (1) having a deck (A), at least one cylinder opening (2,3,4,5) and an open water jacket (10), which is formed into the engine block (1) between a cylinder wall (6,7,8,9) defining the cylinder opening (2,3,4,5) and an outer wall (15), wherein a contact face (11) is provided on the top of the deck (A) for mounting a cylinder head of the combustion engine, the cylinder opening (2,3,4,5) and the opening (12) of the water jacket (10) being formed in the contact face (11), the method comprising the following process steps: a) providing an engine block (1) with an open water jacket opening (12); b) placing an insert (20) in the water jacket opening (12), the shape of the insert (20) being adapted to the shape of the water jacket opening (12) such that the insert (20), when being placed, at least partially closes the water jacket opening (12) and bridges the distance between the outer wall (15) and the cylinder wall (6,7,8,9), thereby supporting the cylinder wall (6,7,8,9) against the outer wall (15) of the engine block (1); and c) fixing the insert (20) in the water jacket opening (12) by friction welding. An engine block produced accordingly shows the advantages of a closed deck engine block. La invención proporciona un método para producir fácilmente un bloque de máquina (1) para una máquina de combustión, el bloque de máquina (1) tiene una cubierta (A), por lo menos una abertura de cilindro (2, 3, 4, 5) y una camisa abierta de agua (10), la cual está formada en el bloque de máquina (1) entre una pared de cilindro (6, 7, 8, 9) que define la abertura de cilindro (2, 3, 4, 5) y una pared exterior (15), en donde se proporciona una cara de contacto (11) en la parte superior de la cubierta (A) para montaje de un cabezal de cilindro de la máquina de combustión, la abertura de cilindro (2, 3, 4, 5) y la abertura (12) de la camisa de agua (10) están formadas en la cara de contacto (11), el método comprende las siguientes etapas de proceso: a) proporcionar un bloque de máquina (1) con una abertura (12) de camisa abierta de agua; b) colocar un inserto (20) en la abertura (12) de camisa de agua, la forma del inserto (20) está adaptada a la forma de la abertura (12) de camisa de agua de tal manera que el inserto (20), cuando está siendo colocado, cierra al menos parcialmente la abertura (12) de camisa de agua y puentea la distancia entre la pared exterior (15) y la pared de cilindro (6, 7, 8, 9), soportando de este modo la pared de cilindro (6, 7, 8, 9) contra la pared exterior (15) del bloque de máquina (1); y c) fijar el inserto (20) en la abertura (12) de camisa de agua mediante soldadura por fricción. Un bloque de máquina producido correspondientemente muestra las ventajas de un bloque de máquina de cubierta cerrado.
