Studi Eksperimental Performansi Mesin Otto dengan Menggunakan Bahan Bakar LPG

Abstract

Common problemsfacedworld today, isthe depletion ofpetroleum reserves. This phenomenon isencouraging peopletoseekalternative fuelthat is expected toovercome these problems. One type ofalternativefuelthatmakes it possible toreplacefueloil, mainlyusedfor motor vehiclesandgeneratorsetsare theLPG. UsingLPGforOtto enginescan be doneby adding apiece of equipment calledaconversionkit. But theobstaclesencountered intheconversionkitis aconversionpricethat is tooexpensiveanddifficulttoobtain.Toovercome these problemsis carried outmodifications to theenginecarburetorOttomanually controlled. The tools usedinthis researchis, the generatorsets, autogasanalyzer, digital tachometer, digital multimeter, stop watch, weights,andscales. Andas aningredient, PertaminaLPGproduction. Dataobtained from thegaugereadingis processedinto theempiricalformula, thenthe datafrom thecalculationspresented intabulatedandgraphicform. Otto engine carburator modification process is still not provide the optimal function, that is too high idle rotation, and to perform acceleration will couse delays of supply LPG into the combustion chamber so that the engine performance decreases
