To sum up, for one entire test cycle, the effect of ethanol
on the reduction of CO and HC emissions is significant.
However, the ethanol fuel improves NOX emission reduction
lightly, even cannot. For five steady-driving stages, the
decrease of CO and HC emissions are obvious at only idle
and 50 km h−1 stages, when E10 fuel is combusted
