Definitions

  • the invention relates to a self-igniting internal combustion engine with combustion chambers for high ignition pressures according to the preamble of claim 1.

It is a arranged between the combustion chamber and the cylinder head the top surface of the combustion chamber forming separate, with the crankcase and / or the cylinder liner positively and gastight connected cooled plate in which the valve seats at least one inlet valve and at least one outlet valve are arranged and the is penetrated by the at least one injection valve.
  • the advantage of such a component is, on the one hand, that the positive connection of the cooled plate with the crankcase and / or the cylinder liner can be made directly to the combustion chamber boundary, whereby the deflection under pressure already considerably minimized compared to today's standard cylinder heads due to the much smaller spans
  • the use of this separate from the crankcase, cylinder head and possibly the cylinder liner component opens up completely new possibilities in terms of material selection.
  • the cooling of the cooled plate is carried out by the cooling medium provided for the cooling of the crankcase and the cylinder head, so that the cooled plate can be advantageously integrated into the existing cooling system.
  • a further advantage of the cooled plate according to the invention is that, due to the better accessibility for the mechanical processing, cooling channels can be introduced into the cooled plate which permit a significantly improved cooling of the combustion chamber roof and the valve seats compared to conventional cylinder heads.
  • the cooling channels can be advantageously formed as outgoing from the peripheral side of the cooled plate holes, which advantageously extend in the cooled plate that they cut other holes and form a connected system of holes. In this case, at least some of the bores are reclosed towards the peripheral side in order to simplify advantageously the inflow and outflow of the coolant.
  • the supply of the cooled plate with coolant can be done easily and thus advantageously so that in the peripheral side and / or in the protruding edge region of the top surface of the combustion chamber forming flat side of the cooled plate and / or the top surface opposite flat side of the cooled plate inflow and / / or outflow openings are provided and the supply of the cooled plate with coolant directly and / or via the crankcase and / or via the cylinder head.

In addition, it may be advantageous for sealing the combustion chamber to provide a seal between the combustion chamber overlapping part of the cooled plate and the crankcase or the Buchsenbund.
