Abstract
Pada penelitian ini motor bensin ( berbahan bakar cair )
akan dicoba dioperasikan dengan bahan bakar LPG ( berbahan
bakar gas). Agar dapat menggunakan bahan bakar LPG, motor
bensin harus dimodifikasi, dengan jalan menambahkan mixer
venturi. Dari penelitian sebelumnya mixer yang sesuai adalah
mixer venturi. Mixer venturi berfungsi sebagai pencampur antara
udara dan bahan bakar, sebelum masuk ke dalam silinder.
Selanjutnya dilanjutkan pengujian untuk membandingkan
genset dengan bahan bakar LPG dan bahan bakar pertalite
menggunakan metode uji konstan speed dengan standart SNI
( Standart Nasional Indonesia ).
Dari hasil eksperimen didapat data bahwa bahan bakar
pertalite lebih effisien daripada LPG. Unjuk kerja terbaik
diperoleh pada putaran mesin 3000 rpm. Dengan data, BHP=
1093,75 watt, Torsi=3,46 Nm, BMEP= 438 Kpa, BSFC= 0,00046
Kg/Wh, dan efisiensi mencapai 13,25%. Sedangkan
menggunakan LPG,pada putaran 3000 dengan data, efisiensi=
2,9% dengan BHP= 1062,5 Watt, Torsi= 3,35 Nm, BSFC=
0,0079 Kg/Wh, BMEP= 425 Kpa.
==================================================================================================================
In this test a gasoline engine (with liquid fuel ) will try
to operate with LPG ( Gas Fuel ). For using LPG fuel, the
gasoline engine must be modified, by adding a venturi mixer.
From previous studies appropriate mixer is a venturi mixer.
Venturi mixer serves as mixing between air and fuel, before
entering into the cylinder.
Furthermore, the next step is testing to compare the
generators with fuel LPG and fuel pertalite with constant speed
test method in standard SNI(Standart Nasional Indonesia).
The experiment result shows that the Pertalite is more
efficient than LPG. The best performance using pertalite was
obtained from the engine at 3000 rpm that the BHP= 1093,75
watt, Torsi = 3,46 Nm, BMEP = 438 Kpa,BSFC = 0,00046
Kg/Wh, and the efficiency= 13,25%. While using LPG from the
engine at 3000 rpm, the efficient= 2,9% with BHP= 1062,5 Watt,
Torsi= 3,35 Nm, BSFC= 0,0079 Kg/Wh, BMEP= 425 Kpa.
