Engine cylinder lubrication system for low speed, two-stroke, crosshead internal combustion engine uses electronic control unit to control lubrication units based on varying cylinder pressures at current engine operating mode
Engine cylinder lubrication system for low speed, two-stroke, crosshead internal combustion engine uses electronic control unit to control lubrication units based on varying cylinder pressures at current engine operating mode
Piston rings (7) move in annular grooves up and down and also rotate about a longitudinal axis, and the cylinder (1) is lubricated by a lubricating unit (10), supplying lubricant to points (11) on the cylinder, while an electronic control unit (17), receiving pressure measuring data from a pressure sensor (14) determines which lubrication unit should be activated. Preferably, at least one pressure sensor is used for each lubrication unit to ensure its correct functionality. Independent claims are included for a method of lubricating and engine cylinder and for a connecting member.
