Topic > Using ethanol as a starting fuel (SI)

Despite low greenhouse gas emissions, the best preferred view of ethanol as a starting fuel (SI) is perhaps its high octane rating and the ability to withstand high weights and temperatures without uncontrolled starting. Since the efficiency of SI engines depends primarily on the pressure ratio and high-octane power ratings are particularly suited to high-pressure ratios, the use of ethanol in SI engines can offer greater energy productivity. The result is that the performance of engines using the E85 blend can be 9% higher than that of gas-fueled engines. One approach to achieving a high pressure ratio is to design the engine with a turbocharger (e.g. Lotus Building on a Toyota engine). For the Brazilian market, Passage has developed an engine for E93 (7% water), which is also ready to run proficiently on E25 (gasoline). Say no to plagiarism.

Concerns in using ethanol to fuel vehicles are related to consumption in the fuel system and in warehouses. The most notable similarity problems found in armada tests include: a) corruption of plastic and elastic materials (i.e. softening and swelling) caused by the solvent idea of ​​ethanol; b) degradation of metals due to the acidic or galvanic nature of ethanol. Although anhydrous ethanol is only mildly destructive, its hygroscopic nature makes water pollution inevitable, with the potential for metal consumption greatly increasing in the presence of water contaminants, such as sodium chloride and natural acids. Minor issues also include plugged fuel lines due to loosened ethanol deposits, cold starting, and increased fuel emissions through dissipation. The above issues are mostly related to existing vehicles that use E10 and older ethanol blends. Upgrading this vehicle to use blends with up to 20% anhydrous ethanol essentially requires replacing some plastic parts on the fuel frames. In basic practice, the low-ethanol blends E5 and E10 are already available worldwide and have generally shown great similarity to existing SI engines. For high-ethanol blends, Portage and other automakers are already offering flex-fuel vehicles, which can continue to run on 0 to 85 percent ethanol blends, with moderately economical engine tunes. In both non-FFVs and FFVs, fuel consumption and corruption issues have been resolved by using treated steel as a replacement for aluminum, magnesium, lead, and other metals. Polyvinyl chloride and some elastic parts have been replaced by materials, for example, high-density polyethylene, nylon and fluorinated plastic, for example Teflon. There is no immediate logical documentation of the engine and fuel structure in Brazilian E100-fueled vehicles, but all in all, automakers' thirty-year experience with hydrous ethanol fuel appears to have eliminated any significant similarity issues through the right selection of materials. As for cold starting problems, current vehicles powered by high ethanol blends use..
