Comparison of Energy Consumption and CO
Reduction with Combined Application of the Start and Stop and Intelligent Alternator in a Flex Fuel Vehicle
There is a worldwide race to adopt measures that are efficient in reducing carbon dioxide (CO2) emissions into the planet's atmosphere and consequently minimize the possibility of global warming. In this regard, several countries have adopted laws and programs that encourage the automotive industry to apply advanced and innovative technologies to increase the vehicles energy efficiency. In many cases the adoption of more than one technology does not mean that the result of energy efficiency is the simple sum of the effects of each one of them. Therefore, the relevance of analyzing the interactivity between technologies is justified. The objective of this work is to present the experimental evaluation of the comparison of energy consumption and CO2 reduction with the combined application of Start & Stop and Intelligent Alternator. In order to measure the reduction of fuel consumption and carbon dioxide, a Flex Fuel vehicle running on gasoline was tested in the emissions cycle FTP75 + Highway, where the CO2 levels and their fuel consumption were measured CO2 levels and fuel consumption with the combined use of both technologies in order to compare with the base configuration (technologies disabled). The results showed a CO2 reduction in urban cycle when compared to the base configuration of 3.85% and 3.48% respectively using Start & Stop and Intelligent Alternator, both isolated. In the combined application of the two technologies the 5.87% reduction in CO2 was obtained in the urban cycle. In terms of energy and fuel consumption reduction the results in urban cycle were close to CO2 reduction. The difference between the sum of the effects of the application of isolated and combined technologies form, justifies the importance of the interaction analysis between them.
