RESEARCH OF OPACITY AND CONSUMPTION AT DACIA SANDERO 1.5 DCI WITHOUT EGR
The study of pollutant emissions, especially of the Dacia Sandero 1.5 dCi passenger car at different operating regimes was developed by monitoring the fuel consumption. The introduction of the study is concerned about pollution, the environmental problem which is met every day. Pollution is about emitting in the surrounding environment chemical components which may lead to the structural imbalance between various life forms, which impacts health and comfort at all levels and causes ambient damage by altering natural and life sustaining factors. Different types of pollution do manifest continuously. First of all the air pollution from automobiles is the most important and analyzed in this study. In it is also considered the ecological design approach of most cars. Another section of the study makes a brief history of the internal combustion engines and their improvement process taking into account the pollutant emissions. Further in the study a comprehensive step is about the evolution of the chemical pollution. Last but not least is a description of the devices for measuring the pollutant emissions of cars. Another chapter enumerates and defines the filters, equipment and systems applied in engine development to meet increasingly stringent pollution standards. The study also contains the experimental part of the work. In this part is presented the measuring system used and then the results acquired from the Dacia Sandero 1.5 dCi engine, by monitoring the variation in the opacity of the exhaust smoke and the evolution of fuel consumption in different engine operating regimes. The last part of the study contains the final conclusions and proposed development perspectives.
