• Quantitative Assessment of Operation of Ship Main Diesel Engine

  Publication

  • J. Rudnicki

  - Year 2011

  Operation of ship propulsion system is associated with realization of definite operational goals. If to elements of the system the operational reliability strategy could be applied, the situation would be very simple as existing conditions would unambiguously determine application of means being on hand. However decision to reject application of the strategy (even if hypothetical) becomes obvious with a view of necessity of ensuring...

• Loads of ship main diesel engine in the aspect of practical assessment of its operation

  Publication

  • J. Rudnicki

  - Journal of Polish CIMEEAC - Year 2008

  W artykule przedstawiono koncepcję metody pozwalającej na ocenę działania silnika pracującego na obciążeniu częściowym. Do określenia istniejącego zapasu parametrów użytkowych silnika oraz związanych z degradacją jego stanu technicznego dodatkowych kosztów ponoszonych przez użytkownika wykorzystane zostało wartościujące (ilościowe) ujęcie działania interpretowanego jako pewna wielkość fizyczna.

• A method for evaluating the performance of a marine piston internal combustion engine used as the main engine on a ship during its voyage in different sailing conditions

  Publication

  • J. Girtler

  - Polish Maritime Research - Year 2010

  Przedstawiono metodę oceny działania tłokowych silników spalinowych napędu głównego staków morskich, nazywanych silnikami głównymi, działających w typowych warunkach ich eksploatacji. Warunki te zostały opisane z uwzględnieniem pola osiągów tego rodzaju silników. Metoda ta umożliwia obliczenie wartości działania w wyniku zastosowania rachunku całkowego. Znamienne jest to, że działanie wspomnianych silników spalinowych zostało przyrównane...

• Assesment of operation of ship main diesel engine using the theory of semi-markovian and markov processes.

  Publication

  • J. Rudnicki

  - Journal of KONES - Year 2009

  To precisely determine the task it is necessary to specify also its duration time, apart from conditions in which it will be realized. When considering propulsion engine, i.e. the main element of ship propulsion system, especially important becomes not only the problem which amount of energy could be at one's disposal but also within which time interval it could be delivered. Therefore apart from applying the commonly used reliability...

  • Z. Kneba
  • J. Kropiwnicki

  - Polish Maritime Research - Year 2017

  With a single approach to modeling elements of different physical nature, the method of Bond Graph (BG) is particularly well suited for modeling energy systems consisting of mechanical, thermal, electrical and hydraulic elements that operate in the power system engine room. The paper refers to the earlier presented new concept of thermal process modeling using the BG method. The authors own suggestions for determining causality...
