Dot 5


Dot 5 Extended layout Diagram

Fewer engine type

Larger lay out areaFewer engines

SMCR (MEP) dependent design of components (Liner cooling, atomizers)

New engine control strategy

What advantages:

Extended layout diagram: extrapolating performance in deep rpm and Pme, new perfomance rules needed

Acceleration performance/heavy running improved

Significantly improved partload SFOC

Tier III technology advantages

Enhanced prediction of expected performance

< 17 >

Dot 5 Why?In short


T/C relevant performance changes:

Lower Pscav

Increased air flow

EGB: reduced bypass ratio (6% to 3%)

Other performance changes:

New cylinder pressures (part load SFOC, acceleration, NOx tuning)

New engine running mode (not ME-B)

Lower Hydraulic pressure curve

< 19 >

What is dot 5 performance strategyChanges


Dot 2 to Dot 5 Transition Period

1. CEAS Dot2 data

2. CEAS Dot5 A data since April 2014

Decreased Scav. Heat Dissipation and decreased Jacket Heat Diss.

3. CEAS Dot5 B data since June 2015

Increased Scav. Heat Dissipation decreased Jacket Heat Diss.

Approx 3% in total


Dot 2 to Dot 5 Transition Period

Owner and yard discuss the cost differences.

What are the impact on engine design.?

What are the impacts on engine room aux. and capacities?

Approxmately 3% increased in combined heat dissipation from scav air

and jacket water cooler

New data for shaft vibrations calculation. Must be checked

Less EEC effect due to

Only comparison of CEAS calculations between the different lay outs can

reveal the exact figures
