“…Specifications for the 2.0t claim 150 hp (112 kW) on gasoline and a 20% increase to 180 hp (134 kW) on E85. The vehicle is equipped with components that are compatible with both 11,15 fuels to prevent corrosion and premature wear . Ethanol content in the fuel is detected by means of feedback control from the oxygen sensor in the vehicle's exhaust system.…”

Saab Automobile recently released the BioPower engines, advertised to use increased turbocharger boost and spark advance on ethanol fuel to enhance performance. Specifications for the 2.0 liter turbocharged engine in the Saab 9-5 Biopower 2.0t report 150 hp (112 kW) on gasoline and a 20% increase to 180 hp (134 kW) on E85 (nominally 85% ethanol, 15% gasoline). While FFVs sold in the U.S. must be emissions certified on Federal Certification Gasoline as well as on E85, the European regulations only require certification on gasoline. Owing to renewed and growing interest in increased ethanol utilization in the U.S., a European-specification 2007 Saab 9-5 Biopower 2.0t was acquired by the Department of Energy and Oak Ridge National Laboratory (ORNL) for benchmark evaluations. Results show that the vehicle's gasoline equivalent fuel economy on the Federal Test Procedure (FTP) and the Highway Fuel Economy Test (HFET) are on par with similar U.S.-legal flex-fuel vehicles. Regulated and unregulated emissions measurements on the FTP and the US06 aggressive driving test (part of the supplemental FTP) show that despite the lack of any certification testing requirement in Europe on E85 or on the U.S. cycles, the vehicle is within Tier 2, Bin 5 emissions levels (note that full useful life emissions have not been measured) on the FTP, and also within the 4000 mile (6400 km) US06 emissions limits. Emissions of hydrocarbon-based hazardous air pollutants are higher on Federal Certification Gasoline while ethanol and aldehyde emissions are higher on ethanol fuel. The advertised power increase on E85 was confirmed through acceleration tests on the chassis dynamometer as well as on-road.

“…Further, no metal-on-metal sliding contact or other tribo-corrosion concepts were included within the test protocol that might occur in practical fuel handling systems, such as pumps or valves. At least one experimental effort [6] has indicated that abrasion mechanisms were more pronounced in E22 than E60 or E100 and that corrosion products could be a participant in wear or abrasion.…”

“…Mostly, the formation of corrosion with ethanol blends on engine components is based on the mechanism of galvanic corrosion 167 . Since the electrical conductivity of ethanol blends is higher than gasoline, any contaminants that increase the electrical conductivity of ethanol cause much more aggressive corrosion 155 . To overcome the corrosion, it is recommended that various FFE components have to be upgraded with premium materials to ensure minimal corrosion issues and maximum life span 168 .…”

Summary Ethanol‐powered spark ignition (SI) engines have the potential to mitigate the twin crisis of fossil fuel depletion and exhaust emissions. However, the successful promotion of ethanol is hindered due to the restriction of fuel blend diversity and design features in the conventional SI engine. The fuel flexibility can be overcome by the use of flex‐fuel engine (FFE) technology with appropriate changes in engine design features for a wide range of ethanol blends. The understanding of FFE based on various technical aspects has greater potential in the automotive sector. Therefore, this review paper provides a holistic approach to critically analyze the various technical aspects of FFE. In this work, the application of ethanol blends on FFE output characteristics is reviewed critically considering the effects of engine operating conditions and parameters. Further, the impact of ethanol blends on material compatibility, cold starting characteristics, and unregulated emissions are analyzed. The outcome of the study shows that combustion and performance characteristics such as cylinder pressure(CP), heat release rate (HRR), and brake thermal efficiency (BTE) are improved in FFE operation due to the clean‐burning characteristics of ethanol blends. Also, carbon monoxide(CO) and hydrocarbon (HC) emissions decreased without any significant improvement in nitrogen oxides (NOx) emissions with a wide range of ethanol shares in FFE. Finally, this study summarizes the present status of research in FFE and creates a route towards the direction of multidisciplinary research need in the future that supports the application of different types of biofuels in FFE.
