“…Masalah utama dari sepeda motor dengan teknologi Fuel Injection yaitu performa mesin yang sering dianggap kurang maksimal oleh pengguna sehingga dilakukan modifikasi dengan menyetel ulang (remapping) ECU untuk meningkatkan tenaga dan torsi [14 -16] , serta efisiensi bahan bakar [17] . Akan tetapi, proses ECU remapping harus dilakukan dengan perangkat lunak (engine tuning software) dan mengikuti prosedur terukur sesuai dengan standar pabrikan sehingga proses penyetelan ECU pada umumnya membutuhkan biaya yang relatif tinggi dan menyita banyak waktu [17] . Oleh sebab itu, banyak pengguna memilih metode alternatif yaitu dengan mengganti Electronic Control Unit standar pabrik dengan ECU aftermarket untuk meningkatkan performa sepeda motor.…”

To improve motorbike performance, simple modifications are often applied using an aftermarket Electronic Control Unit (ECU). However, scientific studies on this particular topic are still limited. Therefore, the purpose of this research is to examine the effect of the aftermarket Juken 5 ECU on the power, torque, emissions, and fuel consumption of the Yamaha R15-V3 bike. The results of the dynamometer testing showed that the motorcycle with the Juken 5 ECU experienced an average increase of 8.09 ± 1.30% in power and 7.79 ± 1.31% in torque, respectively, at 5500 – 11000 rpm. However, the concentrations of Carbon Monoxide and Hydrocarbon emissions also increased by 170% and 360%, respectively. Particulate emission measurements also revealed that the Juken 5 ECU usage resulted in a significant increase in particulate counts. Compared to the standard ECU, motorcycles equipped with the Juken 5 ECU produced 89% and 145% more particulates in the size range of 0.3 – 0.374 μm and 0.374 – 2.685 μm, respectively. The performance and emission data analysis results indicated that the increase in power and torque achieved by the Juken 5 ECU is simply due to more fuel being injected into the combustion chamber. This finding was supported by the results of fuel consumption testing, where using the aftermarket ECU increased motorcycle fuel consumption by 63.6%.

“…Peningkatan nilai kalor pada campuran diduga akibat adanya reaksi antara senyawa penyusun bio-additive dengan senyawa pada premium. Massa molekul senyawa penyususn bahan bakar dapat mempengaruhi tinggi rendahnya nilai kalor saat pembakaran [25]. Tingginya massa molekul pada setiap senyawa penyusun bioadditive orange peel dapat mendorong terjadinya dipol sesaat dengan intensitas yang sering dan berpengaruh pada senyawa lain disekitarnya termasuk senyawa penyusun bahan bakar premium.…”

The addition of bio-additive in gasoline was needed in order to improve the anti-knock quality. The bio-additive used was orange peel in the form of essential oil. Nevertheless, it make any changes of fuel properties affecting standard compliances: physical properties, engine performances and exhaust gas emissions due to some main compound effects of orange oil; limonene up to 90%. The recent study aimed to analyze the blends of bio-additives and premium gasoline experimentally related to improve the fuel properties theoretically. By verifying the blends, they were tested at blending concentration ratio from 1% to 75%. For each blend, the physical properties; kinematic viscosity, density, and calorific value were measured using ASTM D 445, ASTM D 92, and ASTM D 250. The results show that the limonene gave many impacts on the change of properties fuel. Limonene is a non-polar compound with high intramolecular force intensity. It causes a spontaneous dipole and gave propagation effect on premium gasoline molecular compound. The effect influences dynamic molecular distribution by increasing the attractive force between opposite pole of premium gasoline and bio-additives blend. The decrease of intermolecular movement intensity will decrease the viscosity of the mixture. In contrary, the kinematic viscosity of the mixture will increase with increasing bio-additive concentration. In other pysical properties, the premium gasoline-bio-additive blends have low density at 1%, 5%, 10% and 25% addition concentration but it has high heating value of fuel blends.

This study offered an investigation as to how the use of sweet orange peel oil as an additive for premium gasoline can increase octane performance which influence combustion. Sweet orange peel oil-acting as a RON booster-contains monoterpene compounds and oxygenated hydrocarbons which can improve the quality of combustion. The study also aimed to analyze the combustion characteristics of premium gasoline mixture affected by sweet orange peel additives on SI engines. This study carried out tests on an engine fuel consumption and HC emissions. The cyclic rings and methyl groups of monoterpene compounds in sweet orange peel additives contribute to the increase of electronegativity of additives, therefore being able to interfere with the premium gasoline’s compounds which are dominated by aromatics hydrocarbons. It has an impact on the branches of single-bond molecules series of premium gasoline. This makes the premium gasoline cannot be ignited at low temperatures, which results in perfect combustion. In addition, the polarity of triacetin and eugenol, which includes oxygenated hydrocarbons, is able to reduce CO as the avoided gas in combustion. Sweet orange peel additives—processed by maceration extraction method—are added to premium gasoline. There are 3 ratios of additives in this study; orange peel essential oil extracted with a concentration ratio of dried orange peels simplicial to n-hexane (v / v) of 1% (EO A); 0.75% (EO B); and 0.6% (EO C). To determine the effect of the additive, exhaust gas emission testing and fuel consumption measurement were carried out on the 2013 Honda Absolute Revo motorcycle 4-step, SOHC, 1 cylinder, 109.17 cc engine. The exhaust gas, i.e. CO, HC, CO2, and O2 were analyzed using a Stargas-898-type gas analyzer. Furthermore, fuel consumption measurement was carried out at 3500 rpm engine speed. The results show that CO could be reduced by 37.7%, while the remaining O2 was reduced by 17%. The addition of sweet orange peel additives could increase CO2 levels in exhaust gases when compared to premium gasoline combustion without additives. However, the premium gasoline with additive A (EO A) blend tends to produce higher hydrocarbon emissions compared to other types of premium additive proportions. In conclusion, adding sweet orange peel additives to premium gasoline can reduce fuel consumption by 3.3%; 3.2%; and 3.4% for each blend, respectively.
