It also has the challenge of ensuring a sustainable fuel supply for the transport sector. In this scenario, the RenovaBio program gives the directives to promote the use of biofuels as an important source of energy. Besides the above-mentioned strategic aspects, the automotive market demands for the development of future technologies to improve the efficiency of the S.I. engines. With that in mind, the experimental work here described consisted of investigating the influence of the volumetric compression ratio, associated to internal EGR and airflow structure optimization (swirl and tumble) on the fuel consumption of a single cylinder research engine equipped with PFI and DI injection systems and running on E22 or hydrated ethanol. The conclusion of the present work will show that it is possible to improve the fuel conversion efficiency by increasing the volumetric compression ratios above the ones used in the passenger cars sold in Brazil, and that ethanol has many advantages over the fossil fuel due to its antiknocking properties and environment friendliness.

Both the process quality and the output quality of the application were assessed. The findings suggest that the successful execution of the FMEA and DRBFM methods, in the business unit case, is due to the combination of provision of resources, employment of multidisciplinary teams, competence development (training), definition and documentation of the process of application, and integration of the application of these methods with other NPD methods/tools, and, mainly, it results from not considering their application as a perfunctory task. Despite the result generalization constraints, the main limitation of this study was using questionnaires as the only source of data collection. It can be said that the knowledge resulting from this research can assist companies to benefit from applying these methods in the new product development process.

This system can deal with different blends of ethanol and gasoline, ranging from 22% in volume of anhydrous ethanol in gasoline (E22) to hydrated ethanol (93% ethanol and 7% ...

However, the best solution for this dilemma must take into account the geographic and social-economic characteristics of the country, its energy matrix, its emission legislation, and the fuel carbon footprint during its entire lifecycle. Brazil has a strong reputation for its fleet of Flex-Fuel vehicles, long date experience in the use of ethanol fuel and its distribution network. This differentiates it from other global markets and justifies a unique approach for the CO2 emission reduction. This article describes a project with the main objective of optimizing the efficiency of Flex-Fuel engines running on ethanol, without deteriorating their performance with gasoline. The influence of the geometric compression ratio, the airflow structure and the inlet valve opening/closing strategy was investigated for fuel consumption and engine performance. The analysis of the experimental data confirmed the benefits of the compression ratio optimization on the combustion efficiency. Therefore, the development of efficient Flex-Fuel engines will lead to a sustainable route for mobility in Brazil.
