Engine Cleanliness in E85 Powered Flex-fuel Vehicles
نویسندگان
چکیده
E85 is viewed as a potential alternative fuel to decrease fossil CO2 emissions and dependence on crude oil. As for their conventional counterparts, engines powering flex-fuel vehicles deliver optimal performance when the sensitive areas in the intake system are kept clean and free of deposits. Since no standard tests are available for evaluating the tendency of fuels to form intake valve deposits in FFV engines fuelled with E85, interested parties such as fuel marketers or additive suppliers have to run in-house tests. This work focuses on experiments performed in a bench engine and vehicles operated on the road. The results demonstrate that additives based on polyisobuteneamine or polyetheramine are suitable to control the formation of intake valve deposits in this kind of engines.

Feasibility of meeting increased biofuel mandates with E85
The Environmental Protection Agency implements the Renewable Fuel Standard through annual blending mandates for different categories of biofuels. In its proposed rule released for the 2014, 2015 and 2016 calendar years, EPA reduced mandates because the volume of ethanol that consumers can easily use is lower than the original mandates specified in the Renewable Fuels Standard. This study estima...
متن کاملA Study on Fuel Consumption Reduction Using 48-V Mild Hybrid Technology
Due to the air pollution crisis and increase in greenhouse gases, emission standards are getting tougher gradually. In the other hand reducing the consumption of nonrenewable resources is one of the main goals of the automotive industries in the world. Using electric propulsion along with internal combustion engine is one of the answers. Different designs of Hybrid Electric Vehicles (HEV) have ...
متن کاملImpacts of ethanol fuel level on emissions of regulated and unregulated pollutants from a fleet of gasoline light-duty vehicles
The study investigated the impact of ethanol blends on criteria emissions (THC, NMHC, CO, NOx), greenhouse gas (CO2), and a suite of unregulated pollutants in a fleet of gasoline-powered light-duty vehicles. The vehicles ranged in model year from 1984 to 2007 and included one Flexible Fuel Vehicle (FFV). Emission and fuel consumption measurements were performed in duplicate or triplicate over t...
متن کاملBuilding Out Alternative Fuel Retail Infrastructure:
One significant obstacle to meeting aggressive federal and state alternative fuel consumption targets is the relative scarcity of retail fueling stations that carry alternative fuels. Policies that encourage or mandate use of alternative fuel vehicles in government fleets, thereby increasing demand for such fuels, are one popular approach to stimulating further development of the alternative fu...
متن کاملEthanol Internal Combustion Engines
Ethanol Internal Combustion Engines HIGHLIGHTS PROCESS AND TECHNOLOGY STATUS – The use of biofuels (e.g. bio-ethanol and biodiesel) in the transport sector can save significant amounts of fossil fuels and greenhouse gas (GHG) emissions. Internal combustion engines (ICEs) can run on bio-ethanol manufactured from biomass or waste through biochemical processes. Agricultural feedstock such as sugar...
