• Shipbuilding, Semester 3, position 3

The target of this subject is to give a comprehensive insight into the specific matter of IC marine engines, two-stroke, as well as four- stroke ones, and especially of high power engines with complex engine mechanism. The subject is intended for the students of Shipbuilding department who will be given an introduction for further later research into construction specifications of this class of engines and engine systems during professional practical work experience.

General specifications: Adopted basic theoretical and practical knowledge in the field of IC marine engines where fundamental and applied scientific disciplines are entangled. Students acquire basic ability for competent approach to the choice, organization of exploitation and maintenance of diesel engines in the field of marine engine systems.

1.Introductory considerations 2.Specifications of the construction of marine engine parts- immovable and movable, marine engine distribution system 3.Fuel supply system and the supercharging system of the engine. 4. System of lubrication and cooling of the engine. Function, importance and types of lubricating oils for marine engines. Liquid cooling system. Air cooling system. 5. Engine starting and reversing system and operating characteristics of marine engines. Propelling characteristic of the engine. Optimization of the coupling: engine- propeller. 6. Marine engine vibrations. Torsion oscillations of the crankshaft and the transferring shafts. Possibilities of resonance occurrence and the method of its avoidance. 7. Choice of the marine engine as the most important marine driving machine.8. Presentation of marine engine supercharge systems. 9. Marine engine fundaments.10. Steam and gas turbines. 11 Steam boilers. 12. Nuclear power plant.

a) Auditory training: 1. Construction of marine engines. Presentation and analysis of different conceptions, and the construction of marine driving engines, from the lowest to the highest powers. 2. Marine diesel engine fuel supply system. Mechanical regulation systems (pump- pipe- injector, pump- injector), accumulator (common rail) systems, electronic regulated systems. 3.Supercharge engine system- presentation and analysis of the construction of the physical model of turbocharger. 4. Governors of the RPM of marine engines – function and types, division according to the place of assembly, analysis of the construction and the governor operational system. Analysis of the possibilities of electronic governor in optimization of marine diesel engine operating area marine diesel engines. b) Laboratory training: Engine testing- measuring of the propelling characteristics of the engine.
