INTERNAL COMBUSTION ENGINE COMPRISING A CYLINDER HEAD

摘要

The invention relates to an internal combustion engine comprising a cylinder head (1) with a fire deck (7) on the combustion chamber side, at least one injector sleeve (2) detachably connected to the cylinder head (1) for mounting an injection unit, wherein the injector sleeve (2) is screwed to the fire deck (7) on a fire-deck-side first end (5) via a first screw connection (4), and wherein the injector sleeve (2) comprises in the region of the first end (5) at least one radially protruding first bearing area (9) with a first contact face (10) facing the fire deck (10), which contact face rests on a first counter surface (11) formed by the cylinder head (1). In order to increase the rigidity of the cylinder head (1) at low material cost, it is provided that the injector sleeve (2) preferably in the region of a second end (6) facing away from the first end (5) comprises at least one radially protruding second bearing area (12) with a second contact face (13) facing the fire deck (7), which contact face rests on a second counter surface (14) formed by the cylinder head (1).

主权项

1. An internal combustion engine, comprising a cylinder head with a fire deck on the combustion chamber side, at least one injector sleeve detachably connected to the cylinder head for accommodating an injection device, wherein the injector sleeve is screwed to the fire deck on a first end on the fire deck side via a first screw connection, and wherein the injector sleeve comprises in the region of the first end at least one radially protruding first bearing area with a first contact face facing the fire deck, which contact face rests on a first counter surface formed by the cylinder head, wherein the injector sleeve comprises at least one radially protruding second bearing area with a second contact face facing the fire deck, which contact face rests on a second counter surface formed by the cylinder head.
