Experimental Research of Fuel Efficiency and Emissions of a Diesel Engine Using Hydro-gen-Containing Gas

Abstract

The paper presents the relevance of research of the possibility to reduce fuel consumption and emissions of polluting substances. It was found that internal combustion engines causes a number of problems. First of all, it is the depletion of oil resources. Another global problem is environmental pollution. In addition, it was found that the use of renewable and environmentally friendly alternative fuels is a key challenges for meeting energy needs. The article notes that the use of renewable energy sources is one of the many solutions to the problems of using internal combustion engines. It was found out the possibility of using hydrogen-containing gas in diesel engines in order to reduce fuel consumption and exhaust gas emissions. The current state of using of hydrogen-containing gas in internal combustion engines was analyzed in the scientific work. The paper use the preliminary results of stand tests of a diesel engine regarding to its fuel efficiency in terms of fuel consumption per hour and specific fuel consumption using hydrogen-containing gas in the fresh air charge. It was calculated the road fuel consumption of the steady traffic of the bus "BOHDAN". The bus is equipped with a chinese Dong Feng diesel engine. The theoretical and experimental methodology, for researching the environmental indicators of diesel engine using hydrogen-containing gas, was developed. It was presented the developed equipment for conducting experimental research in the paper. It was found out that the using hydrogen-containing gas in Dong Feng diesel allows to increase fuel economy and reduce emissions of polluting substances.
