Opis:
The following paper introduces us to possibility of using visualization to present running point of main marine diesel engine during ship operation. Construction development of ship marine diesel engine going towards more and more power results in large mechanical and thermal load. So ship marine diesel engines of new generation are more susceptible to damage caused by overloading than the ones of older generation. For this reason more and more attention is paid to proper operation of these main marine engines understood as the way of choosing the right parameters resulting in adequate point of engine operation. This kind of exploitation is being reflected in more and more rigorous requirements imposed by ship engine producers concerning the conditions of their exploitation. This paper presents measured parameters during engine operation and of the sometime confirming its current performance. Special attention has been paid to the measurement of torque. Measurement of torque and revolution speed of the main marine diesel engine have been linked with the possibility of visual presentation of running point of the engine. By means of research carried out of HCP Engine Test Bed it was possible to prove effectiveness of succession of measurement instruments and torque meter action. Visualization algorithm which can be used to present field of work and running point of the engine has also been tested.

Opis:
The paper presents introduction to the research on possible supplying ship diesel engines with mixtures of diesel oils and vegetable oils or their esters with accounting for ecological aspects, i.e. exhaust gas purity. Characteristics of vegetable oils and their esters are compared with those of diesel oils; some consequenŹces of their application to diesel engines, mainly for their working process and exhaust gas content, are indicated. Also, influence of combusting their mixtures with diesel oils are discussed in the same context. Scope of the planned research project is shortly presented.

Opis:
The paper presents results of experimental tests being continuation of the research project described in the preliminary report [4]. The tests were carried out on a ship diesel engine supplied with marine diesel oil, and the oil and rape oil methyl esters mixed in different proportions. In the tests special attention was paid to influence of combustion of the mixtures on exhaust gas content, including its noxious components, as well as on possible changes of indicated working parameters of the engine.

Opis:
This paper is a continuation of the previous articles of the authors, published in Polish Maritime Research [1, 2], devoted to pollution of the atmosphere due ship diesel engines in operation. In the paper presented are results of the investigations carried out in the Gdynia Maritime Academy laboratory with the use of a ship one-cylinder diesel engine combusting heavy fuel oil. Two its possible malfunctions: changes of fuel injection pressure and changes of injection advance angle were simulated. Both malfunctions, which might occur as a result of incorrect engine regulation or wearing or contamination of engine elements, were simulated separately. The presented investigations were focused on finding out relationships between the assumed malfunctions and exhaust gas content, especially content of nitric oxides (NOx), very toxic compoŹunds. The paper is ended by several conclusions arising from analysis of the results which have - apart from their cognitive merits - also an utilitarian character as they may be put into practice by ship operators, provided that some limitations resulting from the specific conditions of the reported laboratory investigations are appropriately taken into account.
