Operation Diagnostics of Marine Combustion Engines: Diesel and Turbine
Selected technical diagnostics issues of large power combustion engines, both piston and turbine, targeted at operation of marine (and other) energy systems in which such engines types occur. Technology of diagnosing. Diagnostic methods and means: endoscopic and parametric, that involve these functional units of the considered engines which directly participate within the basic process performance i.e. the conversion of fuel fed chemical energy into mechanical energy, on way of work and heat. Combustion and emission analysis. Special consideration is paid to methods of mathematical modelling and numerical simulations of the processes and their crucial meaning for finding relationships between the parameters of the engine’s constructional structure and the exit parameters of the performance process, defining the diagnostic symptoms and syndromes, and also effectively designing the diagnosing systems.
Keywords: combustion engines, diagnostics, operation examinations
