Abstract
Official abstract text for this publication.
Methods for preventing a premature ignition of a cylinder charge in advance of a planned ignition point in an internal combustion engine are provided. In one method, a pressure in a crankcase of the internal combustion engine is adjusted so as to prevent lubricating oil constituents from being transported from the crankcase to a combustion chamber of a cylinder of the internal combustion engine due to a pressure ratio between the crankcase and the combustion chamber. In another method, an ignition point for a cylinder of the internal combustion engine is adjusted in a given operating range of the internal combustion engine in such a way that the adjusted ignition point brings about a knocking combustion in the cylinder. Internal combustion engines having a device for preventing a premature ignition of a cylinder charge in advance of a planned ignition point are also provided.
First claim
Opening claim text (preview).
1 . A method for preventing a premature ignition of a cylinder charge in advance of a planned ignition point, the method which comprises: providing an internal combustion engine having a crankcase and a cylinder; and adjusting a pressure in the crankcase of the internal combustion engine such that a transport of lubricating oil constituents from the crankcase to a combustion chamber of the cylinder due to a pressure ratio between the crankcase and the combustion chamber of the cylinder of the…
