Abstract

The invention relates to a cylinder liner arrangement for a reciprocating internal combustion engine and a cooling method. The cylinder liner arrangement comprises a cylinder liner, in which a piston is installed, the factory and installed state between a top dead center and a bottom dead center so along a cylinder axis of the cylinder liner reciprocally disposed forth that a top of the piston delimits, together with a running surface of the cylinder liner and on the cylinder liner arranged in the cylinder cover a combustion chamber. The cylinder liner comprises a liner cooling system for cooling the cylinder liner by means of liner cooling fluid and the cylinder cover comprises a cover cooling system for cooling the cylinder cover by means of a cover cooling fluid, According to the invention, the liner cooling system in such a manner decoupled from the cover cooling system that a flow communication between the liner cooling fluid and the cover cooling fluid is controlled or regulated, or that the flow communication between the liner cooling fluid and the cover cooling fluid is prevented.

Description

technical field

[0001] The invention relates to a cylinder liner arrangement for a reciprocating piston internal combustion engine, in particular a longitudinally scavenged two-stroke large diesel engine, and a cooling method for cooling the cylinder liner arrangement. Background technique

[0002] Large diesel engines are often used as ship drive units or also during stationary operation, for example, to drive large generators to generate electricity. In connection with this, the engine is usually operated in continuous operation for a considerable period of time, which means stringent requirements with regard to effort and costs in terms of operational safety and availability. For this reason, in particular long maintenance intervals, low wear and economical maintenance of fuel and operating materials are the main criteria for the operator operating the machine. In particular, the piston movement behavior in the cylinder liners of such large-bore slow-running diesel engin...
