Study Finds Strong Synergy Between Spark Ignition Engine Downsizing and Low-to-Moderate Alcohol Blend Fuels

Green Car Congress

MAY 1, 2009

The researchers found that the combination of technologies allowed improvements in fuel economy over the engine drive cycle. Furthermore, a reasonable improvement in dilution tolerance could be achieved at higher engine loads, which could eliminate over-fueling requirements under such conditions. Cairns et al. SAE 2009-01-0138).

In 1975, General Ernesto Geisel, then-president of Brazil, ordered the country’s gasoline supply mixed with 10% ethanol. The level was raised to 25% over the next five years, which was intended to maintain a constant Brazilian gasoline supply for an ever-increasing demand. These were arguably the first flex-fuel vehicles.
