STUDY OF THE MODEL OF THE COMBUSTION OF ALTERNATIVE FUELS IN SHIP DIESELS

Abstract

Recently, alternative biofuels based on vegetable oils (rapeseed, soybean, sunflower, peanut, palm) and their derivatives are becoming more widespread. Intensive work on the conversion of diesel to biofuel is carried out both in countries with limited energy potential and in countries with large reserves of petroleum fuels, as well as in highly developed countries that have the financial capacity to purchase petroleum energy.

At present, more than 1.5 million tons of biofuels are produced annually in Europe (Germany, France, Austria, and other countries). It is a blended biofuel containing up to 10% methyl ester derived from rapeseed oil.

Analysis of the efficiency of production and economic activities of water transport enterprises shows that the average level of profitability of their basic services is not high. Therefore, there is a need to find reserves to improve the efficiency of transportation and the work of the transport fleet. One of the areas of scientific research is the economic evaluation of the use of resources and, above all, fuel in the company to achieve a useful result in the activity. The problem of finding and evaluating resource-saving technologies of transport vessels is relevant. The situation on the energy market is especially acute given the constant fluctuations in fuel prices. Reserves for reducing fuel costs are the rationing of running operations, the choice of optimal modes of operation of engines on different sections of the flight, the choice of speed, which on the one hand will ensure timely transport operations - and on the other allow fuel savings. The research consists in the possibility of bringing the obtained theoretical provisions to practical recommendations and directly to devices and equipment that will allow the use of alternative fuels in order to improve the environmental and energy performance of marine engines.
