Abstract
The article describes the kinds of lubricators used for lubricating the cylinder liner-piston unit in the MAN Diesel slow-speed diesel engines. It presents the design of the HJ-type mechanical lubricators and the ALPHA lubrication system with the electronic control.
Highlights
The reduction of frictional resistance and wear of the engines mating elements, such as piston and cylinder liner, requires that their friction faces be lubricated
The keeping of the cylinder liner-piston unit in good condition is influenced by proper lubrication system adjustment so that the oil film formed during engine operation can remain intact
When a ship is equipped with CPP (Controllable Pitch Propeller), the engine runs with a fixed speed, and the lubricators and cylinder oil feed rate are controlled depending on mean effective pressure (MEP), Fig. 6
Summary
The reduction of frictional resistance and wear of the engines mating elements, such as piston and cylinder liner, requires that their friction faces be lubricated.
