Summary:

The search for better energetic efficiency of the flexible fuelengines will guide the next design changes in this technology. Theuse of direct injection and the downsizing of volumetricdisplacement compensated by supercharging is a possible solution toreduce the fuel consumption. The direct injection brings thethermodynamic benefits of the charge cooling; the reduceddisplacement reduces the pumping work in partial loads and enginefriction, while the supercharging allows the performance of abigger engine. The combination of these technologies with hydratedethanol (E100 or AEHC) represents a performance and CO₂ reductionopportunity, but also a challenge in terms of cold start anddurability.The objective of this study is to evaluate and compare thebehavior and the potential in full load conditions of an engineequipped with direct fuel injection and turbocharger, usingBrazilian Hydrated Bioethanol (called as E100) and Braziliangasoline (called E22). Instead of using E100 to raise the engineperformance (torque and power), with the adjustment of manifoldpressure, spark advance and air-to-fuel rate, was possible to takethe physical and chemical characteristics of E100 to increase theengine efficiency with same performance, without compromising themain engine parameters for durability
