Abstract

Increasing consumption of fossil fuels, depleting oil reserves and increasingly expensive fuels have forced the use of alternative fuels. Diethyl ether (DEE) can be used as an alternative fuel because it has a high cetane number, low viscosity, and high oxygen content. This observation was carried out to determine the effect of the addition of Diethyl ether on 20% diesel-jatropha fuel mixture to the torque and power produced. Tests carried out on a 4JB1 type direct injection diesel engine with a constant speed of 2500 rpm. The DEE volume used is 5%, 10%, and 15% is volume-based. The test results show 20% jatropha content produces lower torque and power compared to pure diesel fuel (D100). Also, the addition of DEE to 20% diesel-jatropha fuel produces low torque and power but the value is higher than 20% of diesel-jatropha fuel. The highest torque and power reduction trends occurred in the use of DJ20 fuel by 0.0448% when loading 25%. While the lowest decrease in torque and power occurs in the DJ20DEE15 fuel by 0.0112% with 100% loading compared to D100 fuel.

Abstract

Air pollution is increasing due to the high exhaust emissions of motorized vehicles using fossil fuels. The solution is the use of alternative energy. Butanol and Diethyl Ether (DEE) are alcohols that can be used as a fuel mixture and are environmentally friendly. This is because butanol and DEE have high oxygen levels so the oxidation process in the combustion chamber increases and the residual gas results from combustion is better. This study tested the residual gas from the combustion of a 160 cc gasoline engine using a mixture of pertalite-butanol and pertalite-DEE fuels with 5%, 10%, and 15% alcohol percentages. The test results show that adding DEE produces better engine exhaust emissions than adding butanol. CO emissions decreased by 87% using DEE15 while B15 reduced CO by 72%. DEE10 improves HC by 73% while B15 improves HC by 72%. However, DEE15 increases CO2 by 17% and B15 by 11%. Meanwhile, the oxygen content increased by 8% in DEE15 and 6% in B15 compared to pure pertalite.

Abstract

Penggunaan mesin diesel mengalami peningkatan yang menyebabkan tingginya konsumsi bahan bakar sehingga terjadi kelangkaan bahan bakar. Selain itu, emisi jelaga yang dihasilkan mesin diesel pun meningkat. Jatropa merupakan bahan bakar alternatif yang biasa digunakan sebagai pengganti bahan bakar fosil. Namun, jatropa memiliki efek negatif bagi mesin yaitu performa mesin menurun dan emisi jelaga pun meningkat. Oleh karena itu, diethyl ether dipilih sebagai aditif bahan bakar diesel karena berpotensi memperbaiki efek negatif dari jatropa. Tujuan penelitian ini adalah mengevaluasi efek penambahan diethyl ether pada campuran bahan bakar diesel dan jatropa terhadap konsumsi bahan bakar dan emisi jelaga mesin diesel yang dilengkapi dengan sistem EGR. Bahan bakar yang digunakan adalah diesel dan jatropa yang ditambahkan diethyl ether dengan prosentase 5%, 10% dan 15% dari total volume bahan bakar. Hasil pengujian menunjukan penambahan diethyl ether pada campuran bahan bakar mampu memperbaiki penghematan konsumsi bahan bakar dan mereduksi emisi jelaga walaupun masih lebih tinggi dari diesel murni. Penggunaan hot EGR menghemat konsumsi bahan bakar tertinggi hingga 2,25% pada campuran bahan bakar DJ10DE15. Namun, penggunaan EGR meningkatkan emisi jelaga mesin diesel. Peningkatan emisi jelaga tertinggi terjadi pada penggunaan cold EGR  hingga 15,26% dibanding tanpa EGR pada campuran bahan bakar DJ10DE15.

Abstract

Mesin diesel banyak digunakan karena memiliki efisiensi termal yang tinggi dibanding mesin bensin. Hal ini mengakibatkan penggunaan bahan bakar fosil meningkat sehingga bahan bakar fosil mengalami kelangkaan. Jatropa banyak digunakan sebagai bahan bakar diesel alternatif. Namun, penggunaan jatropa menurunkan performa mesin diesel karena viskositasnya yang tinggi. Oleh karena itu, diethyl ether dipilih sebagai aditif bahan bakar diesel yang berpotensi memperbaiki performa mesin akibat efek negatif jatropa. Penelitian ini bertujuan untuk mengobservasi efek penambahan diethyl ether pada campuran bahan bakar diesel dan jatropa terhadap torsi dan daya mesin diesel. Penelitian ini menggunakan mesin diesel injeksi langsung yang dilengkapi sistem EGR. Bahan bakat yang digunakan yaitu diseel dan jatropa yang dicampur diethyl ether dengan prosentase 5%, 10%, 15% dari total volume bahan bakar. Hasil pengujian menunjukan bahwa penambahan diethyl ether pada campuran bahan bakar diesel dan jatropa meningkatkan torsi dan daya mesin akan tetapi lebih rendah dari diesel murni. Hal ini disebebkan oleh tingginya cetan number dan kandungan oksigen pada diethyl ether sehingga proses pembakaran dalam ruang silinder lebih sempurna. Penggunaan hot EGR terbukti meningkatkan performa mesin diesel. Peningkatan torsi dan daya mesin masing-masing 0,9% pada setiap variasi campuran bahan bakar.

Abstract

Mesin diesel digunakan secara luas dan lebih banyak dibandingkan dengan mesin bensin karena mempunyai daya yang lebih tinggi. Hal ini menyebabkan meningkatnya penggunaan bahan bakar fosil yang semakin meningkat serta menimbulkan emisi yang lebih besar. Jatropha merupakan bahan bakar alternatif dari non pangan hayati yang dapat terbarukan, penambahan bahan bakar jatropha tidak mengurai daya mesin. Tetapi menimbulkan smoke opacity yang lebih besar dibanding dengan menggunakan solar murni. Oleh karena itu, diethil ether merupakan salah satu jenis alkohol yang dapat memperbaiki performa mesin diesel dan menurunkan emisi gas buang. Penelitian ini bertujuan untuk mengobservasi efek penambahan diethyl ether pada campuran bahan bakar diesel dan jatropa tanpa EGR terhadap smoke opacity mesin diesel. Penelitian ini menggunakan mesin diesel injeksi langsung yang dilengkapi sistem EGR. Bahan bakat yang digunakan yaitu diesel dan jatropa 20% yang dicampur diethyl ether dengan prosentase 5%, 10%, 15% dari total volume bahan bakar. Hasil pengujian menunjukan bahwa penambahan cairan alkohol Diethyl ether pada bahan bakar campuran diesel dan jatropa pada sisi emisi juga menghasilkan dampak positif yaitu terjadi penurunan emisi smoke opacity. Penurunan nilai smoke opacity tertinggi terjadi pada bahan bakar DJ20DEE15 sebesar 15,665% dibandingkan D100.

Abstract

Community economic activities that encourage motorized vehicles are getting higher. This exacerbates dependence on fossil fuels and air pollution. The outside air that is contaminated with exhaust gases from combustion products is very dangerous for human health. Motorized vehicles such as motorcycles are the largest cause of air pollution. Alcohols have high octane number and low viscosity. The use of ethanol and methanol alcohols is very diverse, so they are easy to obtain. Therefore, alcohol ethanol and methanol are suitable as premium fossil fuel mixtures. This study aims to observe the CO and HC emission characteristics of the gasoline engine using a premium-alcohol mixture of ethanol, methanol. The alcohol concentration was varied from 5% to 15% at 5% intervals. The petrol engine is operated at 2000, 3000, and 4000rpm. Commercial Gas Analyzers are used to measure CO and HC emissions coming out of the exhaust. The results of the observations present the CO and HC emissions of the engine with premium-ethanol fuel, methanol is lower than pure premium (P100). CO emissions from PE15 fuel decreased to 66,30%, and PM15 decreased to 90,63%. Meanwhile, PE15 fuel HC emissions decreased by 58,94%, and PM15 decreased by 68,60%.

Abstract

Indonesia is one of the countries that uses the most motorized vehicles, which increases air pollution and fuel crises. Using biofuel is one solution to overcome this problem. Methanol is used as a mixture of Pertamax to produce environmentally friendly and renewable biofuel. This is because methanol has high octane and oxygen. Mixing methanol in Pertamax was carried out to analyze the impact of Torque, Power, and Exhaust Gas Temperature (EGT) of a 150cc petrol engine. Methanol 5%, 10%, and 15% was mixed into Pertamax with engine speed variations of 1000, 2000 and 3000 rpm. Dynotest is used to measure engine performance and thermocouples to measure EGT. Test results show the highest increase in engine torque and power of up to 25% at a speed of 2000 rpm with the PM15 mixture compared to P100. The highest reduction in EGT value occurred when using the PM15 mixture at a speed of 1000 rpm up to 28% compared to P100. This shows that the addition of methanol to Pertamax increases torque and power and reduces the EGT of the gasoline engine.

Abstract

The development of butanol as a gasoline additive is encouraged by the government to reduce pollution and the fuel crisis. This is because butanol is a green fuel that is environmentally friendly and can be produced. In addition, the octane number and high oxygen concentration in butanol optimize engine performance and improve exhaust emissions. This research correlates engine power and Brake specific fuel consumption (BSFC) with the BTE of gasoline-butanol-fueled engines and identifies the content of Nox compounds in exhaust gases through engine Exhaust Gas Temperature (EGT). The percentage of butanol in gasoline is 5% -15%. Engine speed from 1000-3000 rpm. Dynotest is used to measure BTE while the thermocouple is used to measure exhaust gas temperature. This research proves that the addition of butanol increases energy absorption which is converted into power with effective fuel consumption which means BTE increases. The highest BTE increase was 21.7% in the B15 blend. EGT decreased by 8.6% in the B16 mixture compared to B0. This identifies that the concentration of Nox in the exhaust gas also decreases.
