What is cpr?
Control pressure relief ring top most ring in 2 stroke which have small holes to release exhaust gases so that Compression ring make proper sealing with help of gas forces
Four factors determine the lubricating oil feed rate:
- sulphur content in the fuel oil
- alkali content in the cylinder lube oil
- engine history
- engine load.
Alpha Lubricator or ME Lube operating in ACC-mode
(Adaptive Cylinder oil Control) adapts the lubricating oil feed
rate to the fuel oil sulphur content and the engine load.
ACC factor will depend upon residual BN , high or low top landand iron wear rate
acc factor multiplied by sulphur % = feed rate
How steam pressure is maintained in sea?
By dump the steam , we have controller
By increasing or decreasing the load ...by maintaining air fuel ratio
By opening steam to the tanks so that excess steam can be used
