| dc.description.abstract | This research was conducted to improve the engine performance with ethanol and
gasoline mixture, because from fuel mixture with high concentrate causes value of flash point
and heat evaporation fuels becomes higher. To overcome these, the air that entrance in
combustion chamber heated up to 26°C, 30°C, 40°C and 50°C, the fuel used are E0, E30 and
E50 on 2000 to 8000 rotation. The result of research shows E0 fuel highest torque on 30°C
with a value 8,98 Nm had 0,22% increase, E30 fuel highest torque on 50°C with a value 9,5
Nm had 1,05% increase and E50 fuel highest torque on 50°C with a value 7,77 Nm had 0,64%
increase. On E0 power is 5,96 kW on 30°C had 0,33% increase, the highest power of E30 is
6,29 kW on 50°C had 1,9% increase and the highest power of E50 on 50°C with a value 4,49
kW had 0,89% increase. For the highest consumption is 2000 rotation, for E0 fuel on 50°C
with a value 1,43Kg / Hp.Hour, E30 with a value 1,48 Kg/Hp.Hour on 26°C and E50 with a
value 2,03 Kg/ Hp.Hour on 26°C, this result shows that air heating treatment can improve the
engine performance. | en_US |
