“…Oxy-hydrogen gas obtained through conventional water electrolysis process is known to improve performance and combustion characteristics of both gasoline and diesel engines. Musmar and Al-Rousan [13] reported reduction of 50% in NO and NOx values, 20% in CO and 20-30 % in fuel consumption due to its blending with gasoline and use in a single cylinder engine. Yilmaz and Uludamar [14] bended a constant flow rate of oxy-hydrogen gas with diesel and showed 19.1% increase in engine torque, 13.5% reduction in CO, 5% reduction in HC and average 14 % reduction in specific fuel consumption.…”

Many bio-diesels are tried and tested to reduce vibrations from diesel engines. Oxy-hydrogen gas is known to improve engine performance and combustion characteristics. This paper presents study on effect of addition of oxy-hydrogen in diesel on vibration signals from cylinder head of a twin cylinder diesel engine. Oxy-hydrogen is added in diesel at five different flow rates (100 (B1), 150 (B2), 200 (B3), 250 (B4) and 300 (B5) milliliters per minute). Changes in statistical parameters (Skewness, RMS value, Crest factor, Kurtosis and Peak amplitude) related to vibration signals are studied and compared with respect to non blended diesel (NB). 36.36% drop in skewness from cylinder head is recorded with B3 flow rate. RMS from cylinder head drops down by 6.68% with B3. Crest factor from cylinder head drops down by 7.97% with B2 and 8.14% with B4 blend. Kurtosis from cylinder head drops down by 20.56% with B4 and increases for B5. Peak amplitude of vibration signals from cylinder head shows drop of 13.34% with B1 flow rate of oxy-hydrogen gas. Overall B3 flow rate of oxy-hydrogen is observed to be most effective in reducing vibration signals from cylinder head of a diesel engine. Keywords: Oxy-hydrogen gas; kurtosis; crest factor; skewness; RMS; peak amplitude. I.INTRODUCTION Majority of diesel engines suffer from disadvantage of vibration due to the way in which fuel is burnt inside the combustion chamber and large peak pressure produced during process of combustion. Engines of present days also suffer from vibration especially due to dynamic misbalancing of various rotating and reciprocating parts. With modern techniques like direct injection, high injection pressure systems, electronic fuel injection system with multiple injection patterns of injectors as per the engine demand from electronic control unit the vibrations from these engines are very well under control. Apart from different techniques to predict and reduce vibrations from different engine parts by Charles et al. [5] studied the effect of mahua methyl ester as a diesel substitute on a vibration and noise from a diesel engine. Authors found that the engine vibration and noise levels are dropping down with use of mahua methyl ester and hence complete replacement of diesel with mahua methyl ester is possible. Rao and Rao [6] studied FFT spectrum indicating knocking frequency and the acceleration amplitude in order to investigate the effect triacetin addition to the coconut oil methyl ester on cylinder vibration. Measurement is carried out in radial direction of cylinder in line crankshaft axis. 10% addition of triacetin with coconut oil methyl ester is proven to reduce the cylinder block vibration effectively together with improved performance and reduced emissions. Manieniyan and Sivaprakasam [7] studied time vs. acceleration graphs at different engine locations for a single cylinder diesel engine fuelled with different blends of diesel and bio diesel (mahua MEOM). Significant reductions in vibration signals are recorded due to addition of bio...

IntisariTelah dilakukan pengukuran nilai resistansi fuel cell terhadap variasi lapisan pelat sejajar, hasilnya penggunaan logam SS316 menghasilkan resistansi lebih rendah bila dibandingkan dengan logam aluminium. Dari beberapa variasi lapisan pelat sejajar yang yang dicoba, diperoleh kenaikan arus listrik yang mengalir pada fuel cell. Laju produksi HHO semakin meningkat dengan bertambahnya arus listrik yang mengalir. AbstractResistance measurement of the variation of the fuel cell layers parallel plates has been done, the result is the use of metal SS316 produce lower resistance when compared to aluminum metal. Of several variations of parallelplate layer is tested, obtained increase in the electrical current flowing in the fuel cell. HHO production rate increasing with increasing electric current flowing.KATA KUNCI: I. PENDAHULUAN Bahan bakar fosil merupakan sumber utama untuk memenuhi kebutuhan energi, terutama dalam bidang transportasi. Sebagai sumber energi, bahan bakar fosil memiliki banyak kelemahan misalnya dapat menghasilkan gas CO 2 yang menimbulkan efek kerusakan lapisan ozon sehingga terjadi pemanasan global. Bahan bakar fosil juga merupakan sumber pencemaran udara karena dapat mengemisikan gas seperti CO 2 , NO 2 . Selain itu bahan bakar fosil bersifat tidak dapat diperbaharui sehingga lama-kelamaan bahan bakar fosil akan habis [1].Salah satu solusi yang dapat dipakai untuk mengatasi hal di atas adalah dengan menggunakan oxyhydrogen sebagai bahan bakar mengingat oxyhydrogen tidak menimbulkan polusi dan dapat diproduksi dengan mengelektrolisis air [2]. Oxyhydrogen sebagai bahan campuran dalam bahan bakar bensin juga terbukti mampu meningkatkan efisiensi mesin Otto [3].Pada peristiwa elektrolisis, pemilihan bahan logam sebagai elektroda sangatlah penting mengingat hal tersebut dapat mempengaruhi reaksi kimia yang terjadi. Kuat arus listrik yang mengalir berperan penting dalam menghasilkan mol produk dari proses eletrolisis [4]. Kuat arus listrik bergantung pada resistansi media yang dilewati. Resistansi dari sel eletrolisis pelat sejajar bergantung antara lain pada luas permukaan pelat, jarak antar pelat, jenis logam pelat, dan jenis larutan yang dielektrolisis [5]. * E-MAIL: bachtera@physics.its.ac.id Pada celah yang sempit, fluida akan bergerak dengan kecepatan yang berbanding lurus dengan lebar celah karena adanya gaya adhesi antara molekul fluida dan gaya kohesi antara fluida dengan dinding celah [6]. Pada proses elektrolisis dihasilkan gas yang dapat dipandang sebagai fluida yang akan bergerak pada celah antara pelat. Dengan jarak yang cukup dekat dimungkinkan gas akan terhambat untuk dapat keluar dari fuel cell, hal ini akan berpengaruh pada nilai resistansi larutan.Pada proses elektrolisis air, gas yang dihasilkan yaitu H 2 dan O 2 dapat dianggap sebagai gas nyata yang persamaan keadaannya dapat dinyatakan dengan persamaan Van Der Walls.(1) dengan a dan b adalah konstanta, p = tekanan gas, V = volume gas, T = temperature absolute gas, n = jumlah mol dan R = konstanta gas umum.

RESUMENLos motores de combustión interna a gasolina tienen conocidos problemas de eficiencia térmica y alto índice de emisión de gases contaminantes. Por otro lado, existen procesos químicos y eléctricos que han permitido obtener fuentes de energía limpia del agua. La electrólisis permite mediante un proceso electroquímico la obtención de gas de hidrógeno y oxígeno, de cuya mezcla se obtiene HHO. Las características moleculares del HHO permiten la disminución de gases tóxicos al ambiente y el ahorro de combustibles hidrocarbonados en motores de combustión interna. En este trabajo se investigan los beneficios potenciales de la mezcla de HHO como aditivo a los combustibles fósiles, en particular, la gasolina comercial. Se describe el diseño de un sistema con una celda electrolítica y se evalúa el desempeño de un motor de 110 cm 3 en términos del consumo específico de combustible, potencia, torque y emisión de gases.PALABRAS CLAVE: electrólisis; celdas de oxihidrógeno; motores de combustión interna; energía limpia; combustibles. ABSTRACTGasoline internal combustion engines have known issues related to thermal efficiency and high emission of polluting gases. On the other hand, there are chemical and electrical processes that have provided sources of clean energy from water. Electrolysis allows the production of hydrogen and oxygen gas by means of an electrochemical process, from which HHO is obtained. The molecular characteristics of HHO allow the reduction of toxic gases to the environment and the saving of hydrocarbon fuels in internal combustion engines. In this paper, we investigate the potential benefits of HHO mixtures as an additive to fossil fuels, in particular, commercial gasoline. We describe the design of a system with an electrolytic cell and evaluate the performance of a 110 cm 3 engine in terms of brake specific fuel consumption, brake power, brake torque and gas emissions.
