Dengan exhaust fan, gas karbondioksida yang dihasilkan oleh engine diesel memungkinkan untuk dibuang dengan cepat sehingga tidak memenuhi ruangan dan membahayakan bagi setiap karyawan. Pengoperasian exhaust fan dilakukan sesuai jadwal pengetesan engine. Exhaust fan tersebut digerakkan oleh motor induksi 3 phasa 30 kW dengan putaran nominal secara konstan. Pada saat pengetesan engine dengan nilai aliran gas buang yang rendah, exhaust fan tetap dioperasikan dengan kecepatan nominal. Operasional motor exhaust fan dengan kecepatan konstan seperti ini akan mengakibatkan konsumsi daya listrik yang relatif tinggi dari pada motor dengan kecepatan berubah-ubah sesuai kebutuhan. Sebagai pertimbangan hasil perhitungan untuk engine C 18 Caterpillar kapasitas 831 hp yang sebelumya  membutuhkan operasional exhaust fan dengan daya 24,7927 kW nilai sama untuk semua model engine, setelah penggunaan VSD dapat dikurangi sebesar 14,35 %  menjadi 21,2343 kW saja. Penelitian ini bertujuan mendapatkan probabilitas hubungan antara konsumsi energi listrik, frekuensi pada variable speed drive, putaran motor induksi dan nilai aliran udara pada cerobong exhaust fan. Nilai aliran udara exhaust fan tersebut akan disesuaikan dengan nilai aliran gas pembakaran yang dihasilkan oleh engine. Analisa optimasi motor exhaust fan ini sedianya akan menggunakan Matematic Analysis dan simulasi menggunakan simulink matlab sehingga diharapkan ada solusi untuk melakukan penghematan terhadap konsumsi daya motor, kemudian bisa diterapkan dalam semua pengoperasian motor yang ada di perusahaan.   Kata kunci : variable speed drive, motor induksi, exhaust fan                                                                                                                                            ABSTRACT              The exhaust fan is a rotary blade device which produces centrifugal force to remove exhaust gas from diesel fuel combustion during a full load test. With exhaust fans, the carbondioxide gases that generated by the diesel engine allows to be disposed quickly so that it does not fill the room and harm to every employee. The operation of  exhaust fan is carried out according to the engine test schedule. The exhaust fan is driven by a 3 phase induction motor of  30 kW with constant rotation. When testing the engine with a low Exhaust Gas flow value, the exhaust fan remains operated at rated speed. Operational exhaust fan with a constant speed like this will result in relatively high power consumption of the motor with the speed of change as needed. Considering the calculation results for C 18 engine Caterpillar capacity of 831 hp which previously required operational exhaust fan with 24,7927 kW of equal value for all engine models, after the use of VSD can be reduced by 14.35% to 21.2343 kW only. This study aims to obtain the probability of relationship between electrical energy consumption, frequency on the variable speed drive, induction motor rotation and the value of air flow in the exhaust fan chimney. The value of the exhaust fan air flow will be adjusted to the combustion gas flow value generated by the engine. The optimization analysis of this motor exhaust fan will be using Matematic Analysis and simulation using matlab simulink so it is expected there is a solution to make savings to motor power consumption, then it can be applied in all the motor operation in the company.   Keywords: variable speed drive, induction motor, exhaust fan

Exhaust Gas Emissions

This study presents the use of bio-solution and nano-Titanium dioxide (TiO2) based additives for dosing in diesel and palm biodiesel (B5). The aim of this work is to enhance the performance of a direct injection (DI) engine and to simultaneously reduce the exhaust gas emissions. The basic properties such as kinematic viscosity, specific gravity, flash point, fire point, and carbon residue of the test fuels were measured and accepted in ASTM standards. Overall, diesel-bio-solution and diesel-TiO2 blends show the lower break specific fuel consumption by 13% and 10%, respectively and the lower exhaust gas emissions, as compared with diesel. B5-bio-solution blend provides the break specific fuel consumption decreased by 1.68%, while exhaust emissions were effectively increased in comparison with B5 fuel.

Pollutant regulations are not a matter of concern only for engine manufacturers but they also require policy implementation, commitment and a dedicated effort by industry. In particular, some in the mining industries are expanding their efforts to provide environmentally friendly working procedures and conditions. Use of fuel enhancershas been suggested. The Letšeng Diamond Mine, in Lesotho has taken the lead and commissioned a study on three different fuel additives. For all three fuel additives, three prominent variables were measured, namely diesel fuel consumption, diesel exhaust gases and smoke emission levels. All instruments used were EPA certified andcalibrated or verified according to the specification of the manufacturer and or international best practice to ensure accurate readings. This paper discusses the results obtained on site over a thirteen month study period involving different classes of machinery and under different weather conditions. Product C improved fuel consumption by 9.9% and reduced black smoke by 32%. Pitfalls have been identified with product A and product B that can help to avoid costly trials on other sites, such as rusted and blown injectors, engine failure and corroded seals, valves and cylinders. Further research is required however to determine if these additives will become major role players toreduce emissions and improve efficiency. In conclusion, we cannot ignore the use of fuel additives when talking about diesel pollution and the fact that the additives cou ld assist in reducing harmful emissions even if only one additive appears to be performing positively in terms of consumption and emissions, such as product C. Three strategies have been identified for reducing emissions on diesel earth moving equipment currently in use: engine modifications, exhaust gas treatment and fuel composition modifications. Engine modifications and exhaust gas treatment are considered costly alternatives to achieve reduced exhaust emissions plus these strategies are proven to have little or no positive impact on fuel economy performance. The study has shown one factor clearly – we cannot ignore the effects of additives both with regard to emissions and combustion efficiency.

The instability of petroleum prices in the world market has caused the price of fuel in Malaysia to increase, especially in the transportation sector. As an alternative, a research has been conducted from a technical aspect on the profitability of using hydrogen onboard as fuel for internal combustion engine. The process of producing hydrogen through chemical reaction between aluminum and hydrochloric acid (Al+HCl) has been successfully applied. Applications using a mixture of petrol with hydrogen (P+H2) as an alternative fuel in four-stroke motorcycles have been tested using a chassis dynamometer model ATV Inertial Dyno, 054-500-1K. Hydrogen requirement in the petrol mixing ratio is dependent on the operating system of the engine ignition system which is controlled by hydrogen pressure in the cylinder. Three stages of load test on the engine performance have been conducted on the chassis dynamometer, namely, load test L0 is equal 0 ampere (L0), load test L1 is equal 1 ampere, and load test L2 is equal 2. This results showed 0.7412 mole of hydrogen can be generated through the chemical reaction between 20 grams of aluminium with 250 ml of hydrochloric acid or 1 kg of aluminium can produce 37.06 moles which is equivalent to 108 grams hydrogen. Fuel economy of each load test was 6.5% (L0), 18.5% (L1) and 30% (L2) in grams per kilowatt hour. The rate used in each test load was 100 g/kWh (L0), 80.77 g/kWh (L1), and 112 g/kWh (L2) compared to petrol of 107 g/kWh (L0), 99.23 g/kWh (L1) and 162 g/kWh (L2). Results from the combustion of petrol, air and hydrogen in proportion of 100 g/kWh, 80.77 g/kWh and 112 g/kWh was able to improve the quality of combustion compared to the normal fuel consumption. The total use of sfc achieved 20.3% savings in grams per kilowatt hour for the engine (G + H2) with an average value of 98 g/kWh compared to the engine (G) with an average value of 123 g/kWh. The successful development of a prototype model with a reduction in fuel consumption in the system's ability to meet the basic needs of the internal combustion engine cycle can be beneficial to the development of the automotive industry, particularly in the transport sector.
