(54) Lubrication system


(57) A cylinder lubrication system for an internal combustion engine, particularly a low speed compression ignition engine, is controlled electronically.
Oil supply to the cylinders is from a ring main gallery (22,41) via oil supply devices (16) having electro-magnetically operated valves (19).
An electronic control system (29) actuates valves (19) in response to signals from a timing device (30). Signals may additionally be generated from an oil pressure sensor (28), a flow detector (21) and other sensors detecting other engine operating parameters fed into the electronic control system to adjust and control the lubricant supply.
