Most drivers like the power, price and renewable benefits of E85, but are looking for ways to increase MPGs. Engines designed with gasoline as the primary fuel are not maximizing ethanol’s potential, which can often lead to mileage penalties. However, new technology from manufactures like Ricardo is geared toward running efficiently with ethanol’s higher octane rating.
In a recent interview with Fleet Owner magazine, Robert Kozak, president of Atlantic Biomass Conversions pointed out that, “Such engine designs tap into the positive ability of ethanol to resist early ignition, thus regaining much of the previous fuel economy loss,” Kozak explained. “Higher octane ethanol makes an internal combustion engine operate more efficiently – up in the 30% to even 40% range – while it’s also priced lower than gasoline, on the order of 10 to 15%, because of its lower Btu or energy content.”
The goal is to produce direct injection engines that perform equal to if not more efficiently than current gasoline engines. And this is what Ricardo engine product group has developed in their ethanol boosted direct injection platform. According to Rod Beazley, director of Ricardo, Ethanol’s higher octane rating allows the fuel to withstand compression rates closer to that of diesel engines. The higher the compression rates the better an engine can translate energy into power.
These first steps toward boosting ethanol efficiency in heavy-duty engines opens the door for continued technology innovation and helps solidify ethanol as a desirable choice for drivers.
