- To make small adjustments to each unit make uniform power generation
in every unit.
- Pmax by timing of fuel pump(vit or by shims to pump or cam floating
- Pcomp in ME engines by exh valve timing change.
- Pmax- Pcomp not more than 35 bar to avoid piston ring failure.
Pi adjusted by fuel index.
(But limits are The peak pressure difference can't be more than 3 to 5
for AE And max 10 for ME. Exhaust gas temp diff 40deg C.
Fuel rack should not be adjusted more than 10% Otherwise we have to
change the plunger and barrel)
It is a two dimensional drawing of a three dimensional surface of the ship’s hull form. This plan is very useful for the following information:It is used for marking the location of a hull Damage on this plan by identifying the strake number , letter and frame number so that the exact location of the damage and also suggested repairs are marked in a localised copy. The shell expansion can be used for finding areas of painting surfaces such as topside, boot topping and bottom areas by applying Simpsons rules directly. In the shell expansion the vertical scale used is different from the horizontal scale and a suitable adjustment has to be made when calculating areas. This becomes useful in solving disputes concerning areas of preparation and painting. It gives information on the thickness of the original strake which is indicated by the number in the circle shown in the strake. The quality of steel used is also shown by letters A,B,D E and AH, BH,DH, EH.
