| description | The analysis of literature data, which showed a decrease fuel consumption and smoke emissions of diesel engines during the combustion of water-fuel emulsions based on diesel fuel, was carried out.The combustion of water- fuel emulsions decreases the intensity of low-temperature pollution, which is explained by significant improvement in the quality of the combustion process as a result of micro explosions emulsion droplets and an increase in the contact surface of fuel vapor with the oxidizer.According to the literature data, the use of water-fuel emulsion does not require constructive alterations of the diesel engine and can significantly improve the environmental characteristics of the engine. Based on the experimental and theoretical studies, the relations of the specific increase in the mass of pollution on the excess air factor for different water content of water-fuel emulsion based on low-viscosity fuels were obtained. For evaluation of the joint effect of three factors on the pollution intensity in the statistical processing of experimental data, the Statgraphics Plus for Windows system, providing access to a full set of statistical methods and providing an opportunity to conduct an extended regression analysis was used. Statistical processing of the research results, which showed the prevailing influence on the specific increase in the mass of pollution of the sulfur and water content in the water-fuel emulsion, and then the excess air factor, was carried out. A three-dimensional model and regression equations that take into account the effect on the value of the specific increase in the mass of pollution of the main parameters are obtained. The contour graphs of the dependences of the specific increase in the mass of pollution on the sulfur content, water content in the water-fuel emulsion and the excess air factor are obtained. Analysis of the research results shows that burning of water-fuel emulsions based on low-viscosity fuels with water content of 30% reduces the level of pollution of heating surfaces by 2,36 times. The obtained relations can be used in the design of condensing heating surfaces |
