Study of the possibility of reducing diesel exhaust gas smoke engine bio additives into fuel

Abstract

One of the modern ways to reduce the technogenic impact of the transport sector on the environment is the expansion of the use of biofuels. The article discusses computational studies of the flow of these fuels in a sprayer using the Ansys Fluent software package. The stationary flow of the specified fuels into the sprayer of a diesel nozzle of the FDM-22 type Plant was simulated which was manufactured by the Noginsk Fuel Equipment Plant with a sprayer of the Altai Precision Products Plant was simulated. The sprayer had five spraying holes with a diameter of 0.35 mm. At the same time, the pressure at the entrance to the design area was 51.5 MPa, and the back pressures were 0.1 and 8.9 MPa. While comparing the flow of rapeseed oil, to the flow of the emulsion of rapeseed oil and ethanol has a higher injection rate. However, compared with the flow of petroleum diesel fuel, it has a lower injection rate.
