“…Проблема розвитку методів об'єктивного контролю параметрів робочого процесу суднових малообертових двигунів з механічними системами управління продиктована ще й тим, що протягом останніх років відбувається серйозне посилення екологічних норм, а екологічні показники, як відомо, жорстко пов'язані з технічним станом двигуна та режимами його роботи. Крім того, активно ведеться пошук нових видів палива для суднових двигунів, які будуть більш екологічними, ніж традиційні [12][13][14], що також буде потребувати більш глибокого контролю робочого процесу, особливо у разі модернізації цих ДВЗ, що вже знаходяться в експлуатації.…”

Technical condition assessment of marine internal combustion engines by the parameters and nature of the workflow is a common practice in their operation. Taking and analysis of indicator diagrams is a mandatory procedure provided by the rules of technical operation for the main range of large and medium-sized marine engines. There is a whole arsenal of indication means for such evaluation: from classical mechanical systems to electronic means of periodic or continuous action. The rapid development of electronic control systems and changes in approaches to logistics operations in maritime transport have imposed a number of limitations, somewhat narrowing the possibilities of using these methods. Most of the vessels that form the basis of the world merchant fleet were built 10...15 years ago. Information about the results of the indication of the engines of such vessels during bench tests is presented in the form of raster images. This complicates the process of using them as the reference needed to compare them with the actual diagrams obtained in operation by means of electronic control systems, which have replaced mechanical indicators over the past few years. In addition, tendencies to reduce the speed of vessels complicate, and often make it impossible to indicate the engines in the specified operating modes. As a result, the efficiency of using indicator diagrams to assess the current technical condition is sharply reduced. In this regard, there is an objective need to compare different methods of obtaining and storing information about the results of indication and in a unified method of presenting this information, convenient for processing and analysis. In addition, there is a need to develop methods for obtaining reference diagrams for nonspecific modes on the basis of processing the results of acceptance and commissioning bench tests of a particular engine to assess its technical condition by the results of indication on the partial load modes. This study is devoted to the comparison of different methods of presenting information and obtaining reference indicator diagrams for non-specific operating modes of engines.

“…However, it is the extremely wide application of ICE has caused a number of global problems, related to the depletion of world oil reserves, atmospheric pollution with toxic substances, global warming etc. There is a solution that allows to partially solve the mentioned problems through application of alternative fuels in internal combustion engines [3,7,10,13,15]. In this content a water-fuel emulsion (WFE) could be treated as one of the most promising type of alternative fuels due to the combination of the unique properties, characteristics, production and operation features [1,2,5,14].…”

Due to unique properties, production and operation features, water-fuel emulsion (WFE) could be considered as one of the most promising type of alternative fuels for diesel engines. Experimental research showed that comparing to traditional diesel fuel, application of water-fuel emulsion allows to reduce nitrogen oxides and soot emissions, which is due primarily to a decrease in the level of maximum temperatures in the engine cylinder, as well as a more uniform distribution of fuel over the combustion chamber volume thanks to its secondary dispersion (micro-explosion phenomena). To control the stability of water-fuel emulsion properties during engine operation it is recommended to install water content sensor in the fuel supply system.
