Abstract
Penggunaan mesin diesel yang diprediksi akan meningkat setiap tahunnya dapat menyebabkan kelangkaan pada bahan bakar fosil. EBT yang saat ini mulai banyak digunakan yaitu berasal dari minyak kelapa sawit (crude palm oil) seperti biodiesel. Namun penggunaan bahan bakar biodiesel memiliki performa mesin yang lebih rendah dibandingkan dengan bahan bakar fosil. Penelitian ini menggunakan bahan bakar dexlite, biodiesel B30 dan biodiesel B30 yang sudah ditambahkan dengan zat aditif yaitu eco diesel. Eco diesel diklaim mampu meningkatkan performa serta mengurangi emisi pada mesin diesel. Pada setiap bahan bakar dilakukan tiga pengujian yaitu, uji properties bahan bakar, uji performa dan emisi mesin diesel. Uji performa mesin diesel dilakukan dengan putaran konstan pada 2200 rpm dan beban yang bervariasi dari 500 W hingga 4000 W dengan interval 500 W. Dari hasil penelitian didapatkan hasil bahwa bahan bakar Dexlite memiliki performa yang lebih tinggi dibandingkan bahan bakar B30 dan B30 dengan penambahan zat aditif Eco Diesel. Penurunan nilai torsi pada bahan bakar B30 dan B30+Eco Diesel jika dibandingkan dengan dexlite berturut-turut sebesar 1,8% dan 0,57%. Namun terjadi peningkatan nilai torsi pada bahan bakar B30 setelah penambahan Eco Diesel yaitu sebesar 1,25%. Penurunan nilai BMEP pada bahan bakar B30 dan B30+Eco Diesel jika dibandingkan dengan dexlite berturut-turut sebesar 1,87% dan 0,57%. Namun terjadi peningkatan nilai BMEP pada bahan bakar B30 setelah penambahan Eco Diesel yaitu sebesar 1,32%. Peningkatan nilai SFC pada bahan bakar B30 dan B30+Eco Diesel jika dibandingkan dengan dexlite berturut-turut sebesar 17,14% dan 5,7%. Namun terjadi penurunan nilai SFC pada bahan bakar
B30 setelah penambahan Eco Diesel yaitu sebesar 9,8%. Penurunan nilai efisiensi termal pada bahan bakar B30 dan B30+Eco Diesel jika dibandingkan dengan dexlite berturut-turut sebesar 13,7% dan 6,2%. Namun terjadi peningkatan nilai efisiensi termal pada bahan bakar B30 setelah penambahan Eco Diesel yaitu sebesar 8,7%. Penurunan nilai smoke opacity pada bahan bakar B30 dan B30+Eco Diesel jika dibandingkan dengan dexlite berturut-turut sebesar 10,3% dan 17,3%. Jika dibandingkan dengan bahan bakar B30, nilai smoke opacity menurun sebesar 7,8% setelah penambahan Eco Diesel.
================================================================================================
The use of diesel engines which is predicted to increase
every year can cause a shortage of fossil fuels. EBT which is
currently being widely used is derived from crude palm oil such as
biodiesel. However, the use of biodiesel fuel has lower engine
performance compared to fossil fuels.
This research uses dexlite fuel, biodiesel B30 and biodiesel
B30 which has been added with additives, namely eco diesel. Eco
diesel is claimed to be able to improve performance and reduce
emissions in diesel engines. For each fuel, three tests were carried
out, namely, fuel properties test, performance test and diesel engine
emissions. Diesel engine performance tests were carried out with
constant rotation at 2200 rpm and varying loads from 500 W to
4000 W at 500 W intervals.
The results showed that Dexlite fuel has a higher
performance than B30 and B30 fuel with the addition of Eco Diesel
additives. The decrease in torque values for B30 and B30+Eco
Diesel fuels when compared to dexlite was 1.8% and 0.57%,
respectively. However, there was an increase in the value of torque
on B30 fuel after the addition of Eco Diesel, which was 1.25%. The
decrease in BMEP value for B30 and B30+Eco Diesel fuel when
compared to dexlite was 1.87% and 0.57%, respectively. However,
there was an increase in the value of BMEP on B30 fuel after the
addition of Eco Diesel, which was 1.32%. The increase in SFC
value in B30 and B30+Eco Diesel fuels when compared to dexlite
was 17.14% and 5.7%, respectively. However, there was a decrease
in the value of SFC in B30 fuel after the addition of Eco Diesel,
which was 9.8%. The decrease in the value of thermal efficiency
on B30 and B30+Eco Diesel fuels when compared to dexlite was
13.7% and 6.2%, respectively. However, there was an increase in
the value of thermal efficiency in B30 fuel after the addition of Eco
Diesel, which was 8.7%. The decrease in the value of smoke
opacity in B30 and B30+Eco Diesel fuels when compared to
dexlite was 10.3% and 17.3%, respectively. When compared to
B30 fuel, the value of smoke opacity decreased by 7.8% after the
addition of Eco Diesel
