PENGARUH PENAMBAHAN BROWNS GAS TERHADAP KINERJA MOTOR BENSIN YAMAHA VEGA ZR 115 CC

Brown's gas (HHO) is a mixture of H gas (Hydrogen) and O gas (Oxygen) in the ratio of 2:1 is generally produced from the electrolysis process. Electrolysis is the process of molecular breakdown HO (water) into Hand O the influence of electrical energy. HHO gas has a high energy when burned up to three times the energy of premium fuel per unit of weight and has excellent combustion properties that can be used to improve the performance of combustion and exhaust emissions from gasoline engines. research on HHO gas is already quite a lot. This paper is a study of experimental behavior for HHO effect on gasoline four-stroke engine twowheeler (motorcycle). HHO gas is injected into the combustion chamber through the intake manifold by varying the flow-rate of HHO by varying the revolution shaft engine. HHO injection varies at 0 ml/s, 1 ml/s, 2 ml / s, and 3 ml/s. Rotation of the motor also varies from 3000, 3500 rpm to 4200rpm performance. observation from this study is the engine performance (output power, sfc,), emissions (CO and HC). With the addition of HHO gas to gasoline motor can improve performance four-stroke enginePowerHHOgasincreaseson the addition of3ml/sby 27,6% with amotor rotationof 4000rpm, SFCdecreasedapproximately31.4% at 4000rpm. The addition ofHHOalsoimprove the quality ofthe exhaust gasof about20% COandHCcontentdecreases to27.6%
