ANALISA VARIASI JUMLAH LILITAN PADA ALAT PENGHEMAT BAHAN BAKAR TERHADAP EMISI GAS BUANG MOTOR BENSIN 4 LANGKAH
Process combustion of fuel in room burn to be influenced by many factor , among others is temperature, closeness of mixture, composition, and turbulensi exist in mixture. When fuel temperature with air mount, hence will progressively easy to fuel with the air to on fire.Gas emission throw away which is yielded from combustion process at motor vehicle can have the character of poison and make negative effect at environment around, the mentioned in causing by less perfect combustion process, gas result of less the combustion perfect for example is CO, HC.The purpose of this study was to determine the effect of the use of electromagnets in the fuel line gasolin engine 4 step with variations in the number of windings on exhaust emissions and fuel consumption . The study was conducted in Laboratory Convert Energi Majors Technical Engineering Faculty Of Technique University Jember . Equipments which is used in the testing is Motor gasoline 4 Step with machine brand Honda Supra x 125D, Gas Analyzer , buret, measure glass, stop wach, tachometer , and accumulator 12 volt. used by materials is Premium RON 88, strand of metal have diameter to 0,6 cm, pipe have diameter to 1" with length 12 cm, and ring 18 cm.This study focuses on the variation of the number of windings on fuel saving devices on exhaust emissions of petrol 4 step. Analysis of the data sought includes AFR, Magnetic Field, Ampere each variation, emissions of CO gas (%), CO2 emissions (%), HC emissions (ppm), O gas emissions (%). Fuel Consumption (FC). From the research 2conducted, it can be concluded that the larger the number of winding electromagnets, the more binding the amount of oxygen in the combustion chamber , so it would be more optimal combustion. The lower the value of the FC (Fuel Consumtion), the lower the fuel consumption required for the performance of the engine. Variations in the amount of electromagnetic windings affect fuel consumption . Fuel consumption is the most efficient use of the variation found in the number of windings of the coil 1000 fuel standard state conditions of 0.57 Kg / hr to 0.43 Kg / h at 3000 RPM rotation with increased efficiency of about 8.14% . Although these results are smaller than the results of previous research by 20.35 % , but at engine speed 9000 RPM FC results of this study resulted in a lower , ie 0.81 Kg / hour compared to 1.19 Kg / hour.
