IMPROVING FUEL EFFICIENCY AND ECOLOGICAL SAFETY OF OPERATION OF THE ENGINE D-240 BY APPLYING WATER INJECTION
The article presents the results of research on improving the fuel efficiency and environmental safety of the D-240 engine by using water injection. The relevance of the use of water (water vapor condensate) as an additive to hydrocarbon fuel is shown, which contributes to the increase of power, fuel efficiency and ecological safety of the operation of the internal combustion engine. Taking into account the constant growth of prices for energy carriers, the increase in productivity and fuel efficiency of machine and tractor units determine the effectiveness of mechanized processes in agricultural production. Reduction of energy consumption is possible due to the use of perspective and modernization of existing structures of fuel systems of engines of tractors and agricultural machinery, including the use of alternative fuels that allow. In order to visualize the economy of diesel fuel using water injection based on the data of external speed characteristics, the combined characteristics of the D-240 engine for diesel fuel consumption were constructed depending on the effective power. The analysis shows that when using water injection with a water fraction equal to 30%, the relative savings of diesel fuel reaches 36 g / kW of effective power. As a result of the processing of the D-240 engine identification data, it was found that when using water injection (30% of the cyclic supply of diesel fuel) a steady increase in the indicator pressure was observed, on average by 18...22%.
