Definitions

the invention relates to a reciprocating piston internal combustion engine with at least one cylinder insert, in which a piston having a plurality of piston rings is movably arranged, and with a row of lubricating oil bores arranged essentially in a plane lying at right angles to the longitudinal axis of the cylinder insert, which are connected to a common lubricating oil supply and which in Lubricate grooves that are located in the outer surface of the cylinder insert adjacent to the piston.
the invention has for its object to improve the lubrication in a reciprocating internal combustion engine of the type mentioned in such a way that both the corrosion attack and wear are drastically reduced.
this object is achieved in that a further row of lubricating oil bores is provided in the cylinder insert, essentially arranged in a plane perpendicular to the longitudinal axis of the cylinder insert, which are connected to a common lubricating oil supply and which end in lubricating grooves that adjoin the piston in the one Shell surface of the cylinder insert are attached, that the lubricating oil supply to the further row is independent of the first row and that the first-mentioned row of lubricating oil holes is in an area which - based on the position of the top piston ring in top dead center - is below this position and whose limits are between 5 and 18% of the piston stroke, and the further series of lubricating oil holes is in an area below, whose limits are between 20 and 40% of the piston stroke.
This design enables the lubricating oil supply to each lubrication area to be individually adapted to the different operating conditions in these two areas. This can be done by adding the same or different amounts of the same lubricant or the same or different amounts of two different lubricants to the two lubrication areas.
a piston 2 is guided to move up and down. In the position shown, the piston 2 is in the top dead center position.
the piston 2 is provided with a plurality of piston rings 3, which are accommodated in a known manner in ring grooves of the piston and bear with their outer peripheral surface on the inner circumferential surface 1 'of the cylinder insert 1.
a series of lubricating oil bores 5 are provided which penetrate the cylinder insert and end in a plane lying essentially perpendicular to the longitudinal axis of the cylinder insert on the lateral surface 1 '.
the area in which the lubricating oil bores 5 are arranged lies below the uppermost piston ring 3 when the piston 2 is in its top dead center position. The limits of this range are between 5 and 18% of the piston stroke.
the second lubrication area formed by these lubricating oil bores 6 has its limits between 20 and 40% of the piston stroke.
the lubricating oil holes 5 and 6 open into lubricating grooves 5 'and 6', which in the inner lateral surface 1 ' Cylinder insert 1 are incorporated and extend transversely to the direction of movement of the piston 2.
a separate lubricating oil supply 7 or 8 is connected to each row of the lubricating oil bores 5 and 6 and each of these contains an adjusting element 9 or 10 in order to be able to individually adjust the amount of lubricating oil to be supplied to the associated row of lubricating oil holes.
