Artigo Completo:

In the next 15 years, the Brazilian government faces the difficult task of honoring the environmental commitment assumed at COP21 to reduce in 43% the GHG emission contributing to the global warming effect. 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.
