STUDY OF THE OPERATION OF THE DIESEL ENGINE 4H 11,012,5 ON MIXTURES OF DIESEL FUEL WITH BIOGAS

Abstract

One of the main tasks in the operation of automotive vehicles is the development of measures to protect the environment from toxic components of exhaust gases (exhaust) of internal combustion engines. Biogas is one of the most environmentally friendly fuels for vehicles, as it produces minimal emissions of carbon dioxide and particulate matter. The gas engine runs quieter, vibration is reduced, which helps to improve the working conditions of drivers. The article is devoted to the development of new fuel compositions based on diesel fuel (DT) and biogas (BG) that meet the requirements of their application in diesel. The article is referred to effective performance of a diesel and the performance of its opacity and toxicity when operating on mixtures consisting of 85% diesel + 15% HD and 70% diesel + 30% BG at different values of the angle of installation of an advancing of injection of fuel. The results of bench tests of diesel when working on these fuel compositions are given. Based on the analysis of the experimental data, the optimal regulation of the fuel supply equipment was determined. According to the results of bench tests of diesel engine with mixtures of BG following conclusions: 1) When using diesel fuels with the addition of 15% HD and 30% BG optimum installation angle of an advancing of injection should be considered ?vpr angle=22?; 2) Operation diesel with additives 15% HD and 30% BG, the amount of heat, allows to reduce the consumption of diesel fuel, respectively, 15% and 30%; 3) The diesel engine works on mixed fuels with the addition of the BG is accompanied by a reduction in emissions from the exhaust gases of soot particles tend to be around the expected range of variation of the angle setting; 4) Work on mixed diesel fuels with the addition of BG in the whole considered range of variation of the angle of installation is accompanied by an increase of emissions in the EXHAUST gas of nitrogen oxides and unburned hydrocarbons.
