Development of a New Electronically Controlled Cylinder Lubrication System
Contraposing defects of the conventional mechanical lubrication system, a new electronically controlled cylinder lubrication system was developed. Its constitution, working principle, control strategy and features were described, and the performance experiments were conducted on the test bench and real ship. The main performance data are as follows: oil injection pressure 2MPa; injection timing precision 0.1ms; injection duration 20ms. The oil injection concentrates onto the piston rings zone to ensure the cylinder liner lubrication, and the oil injection frequency is regulated according to engine load, sulphur content in fuel, cylinder liner run-in condition and so on, thus the cylinder oil consumption rate can be reduced approximately by 30% compared to the conventional mechanical lubrication system. As a retrofit on vessels in service, the Lubrication System will have a payback period of less than two years on most types of MC/MC-C engines.
