The calculation results based on the recorded pressure diagram show that the flame development and rapid burn angles of gasoline-ether blends decrease largely and the maximum cylinder pressure increases as compared with those of gasoline. The flame development angle decreases and the rapid burn angle reduces largely when the fraction of alcohol fuels in gasoline is small, whereas the flame development and rapid burn angles increases if the fraction of alcohol fuels in gasoline is large. The experimental results show that the engine exhaust hydrogencarbon emissions can be reduced by blending the oxygenated fuels in gasoline compared with that operating on neat gasoline, the engine hydrogencarbon emissions can be greatly reduced by operating on gasoline-ether blends rather than operating on gasoline-alcohol fuel blends.
