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

Green Car Congress

MAY 1, 2009

A study by engineers from Mahle Powertrain Ltd and BP found strong synergy between spark ignition (SI) engine downsizing and fuel containing low-to-moderate amounts of alcohol, including ethanol and butanol. The team presented a paper on their work at the recent SAE 2009 World Congress in Detroit. Cairns et al.

The Brazilian experience shows that the presence of small (<10%) amounts of water in the fuel does not in itself cause a greater tendency to misfire in spark ignition engines than a proportionate leaning of the fuel/air mixture would do, provided that the vapor pressure of the hydrated ethanol at the ambient temperature is high enough.
