| dc.description.abstract | This research aims to develop technology that is
used to improve engine performance and to reduce
detonation by using a water injection system. The use of
water as additional fuel, have been around since the
internal combustion engine found. It's just the old water
injection system where is manually driven, so that the
proportion of fuel mixture is not right. Its development is
providing microcontroller-based electrical automation
systems. With this new system, the engine performance of
a motorcycle to be better.
The research used experiment method. The experiments
were done on a motorcycle using a microcontroller-based
water injection (WaI). The microcontroller is used to
automatically adjust the water injection to inject distilled
water (aquades) and methanol into the fuel chamber.
Microcontroller-based WaI system is mounted on the
motorcycle with the fluid composition: (1) Distilled
water/Aquades: 100% (A100%), (2) Distilled water 90%,
methanol 10% (A90% + M10%), (3) Distilled water 80%,
methanol 20% (A80% + M20%), (4) Distilled water 70%,
methanol 30% (A70% + M30%), (5) Distilled water 60%,
methanol 40% (A60 %+ M40%), (6) Distilled water 50%,
methanol 50% (A50% + M50%). Testing is done by
measuring engine performance parameters includes the
torque, power, mean effective pressure, and specific fuel
consumption.
Based on the experimental result, we got the conclusion:
(1) there is a positive effect of microcontroller-based WaI
at the engine performance on the torque, power, mean
effective pressure, and specific fuel consumption. This
result compared with the motorcycle without
microcontroller-based WaI. (2) The highest torque
achieved with microcontroller-based water injection
(Aquades 50% + methanol 50%) is 14,29 Nm at 6250 rpm
and the lowest torque with microcontroller-based water
injection (A100%) is 13,07 Nm at 6162 rpm. (3) The
highest power achieved with microcontroller-based water
injection (M50% +A50% ) is 10,22 kW at 7724 rpm and
the lowest power generated with microcontroller-based
water injection (A100%) is 9,27 kW at 7049 rpm. (4) The
highest mean effective pressure with microcontrollerbased
water
injection (M50% +A50%) is 288,32 kN/m
at
6250 rpm and the lowest mean effective pressure with
microcontroller-based water injection (A100%) is 261,84
kN/m
2
at 5750 rpm, 6250 rpm and 6500 rpm. (5) The
lowest Specific fuel consumption used microcontroller-based water injection (M50%+A50%) are at 5500 rpm,
6500 rpm and 7500 rpm with 0,0734 Kg/kWh. | en_US |
