of ethanol fumigation.
3. The diesel substitution and the energy replacement increases with
an increase in an ethanol fumigation rate at a constant engine speed.
4. The NO emission level and the exhaust gas temperature decreases with
x
an increase in a ethanol fumigation rate at a constant engine speed.
5. The CO emission level increases with an increase in an ethanol fumi-
gation rate at a constant engine speed.
6. The smoke level decreases with an increase in an ethanol fumigation
rate at a constant engine speed.
7. The fumigation rate of 1.06 kg/h (40% diesel substitution) is optimal
for good engine performance.
