<p>At an engine of the crosshead type, especially a big sized two stroke diesel engine, having a crankcase (1) as well as at least one cylinder (3) containing a cylinder liner (4), which extends in a surrounding scavenge chamber (7) and is ending above a chamber bottom (8) of the scavenge chamber (7), and wherein a piston rod (11 ) is provided, which connects a piston (5) going up and down within the cylinder liner (4) with an associated crosshead (10) arranged in the crankcase (1 ), and which penetrates a seal packing (15) provided in the chamber bottom (8), pollution of the system oil of the crankcase (1 ) by cylinder oil and/or combustion residues can be prevented in that the blast generated during the start of the piston upstroke and passing the lower edge of the cylinder liner (4) is diverted from a radial direction to an at least mostly axial direction.</p> |
