Abstract

The characteristic of spray largely determines of combustion quality. Before testing the fuel of diesel engine, characteristic of spray is needed to know. Biodiesel made from nyamplung seeds (callophyllum inophylum) mixed with diesel oil for spray characteristics test. The research was conducted at 1 atm ambient pressure, 15 MPa injection pressure. The fuel used Oil diesel added biodiesel variation B0, B20, B30, dan B100. The fuel mixture sprayed by nozzle tester and recorded using a 480 fps camera at 224x168 resolution to cognize spray tip penetration and spray angle. The result of research showing viscosity of fuel mixture has huge impact on spray characteristic. At high viscosity, longer spray tip penetration longer and smaller spray angle. Its affects the homogeneity of the mixture of fuel and the air. Keywords: spray characteristic, biodiesel, callophyllum inophylum

Abstract

Spray characteristics have an important role in improving the quality of combustion in compression engines. This study analyzes the effect of ambient temperature on spray characteristics including spray tip penetration, spray angle and velocity of spray. The research method uses an experimental method with ambient temperature variations of 60oC, 80oC, 100oC controlled using a thermocouple and an ambient pressure of 0.3 MPa. the composition of the fuel uses diesel (diesel 100%), B30 (30% biodiesel), B100 (100% biodiesel). Image recording using camera speed 480 fms. Based on the experimental results, the ambient temperature increases the spray angle and B100 at all ambient temperatures has a spray tip penetration, velocity of spray is lower.

Abstract

Perkembangan energi alternatif di zaman modern saat ini sangat menarik mengingat energi di alam yang diperoleh dari proses penambangan yang jumlahnya semakin terbatas. Jika terus dibiarkan maka dapat menimbulkan krisis dan kelangkaan energi di masa mendatang. Metode yang digunakan dalam penelitian ini adalah metode eksperimen. Pengujian dilakukan dengan penambahan HHO pada bahan bakar pertalite, terhadap uji konsumsi, emisi gas buang dan performa pada kendaran bermotor dengan variasi putaran 1000 sampai 7000 rpm. Hasil dari penelitian uji performa didapatkan hasil analisa data daya dengan peak performance memperoleh hasil 8,92 Nm pada rpm 8.500, pengujian daya dengan penambahan HHO memperoleh peak performance hasil 14,27. Untuk pengujian konsumsi bahan bakar pertalite dengan penambahan HHO mendapatkan angkah konsumsi 17 ml, sedangkan pengujian konsumsi pertalite tanpa HHO mendapatkan angkah konsumsi 33 ml pada 7.000 rpm. Untuk pengujian emisi gas buang menggunakan bahan bakar pertalite dengan penambahan HHO mendapatkan nilai CO 2,74%, HC 41 ppm, CO2 13,35% dan O2 0,39%, sedangkan tanpa HHO mendapatkan nilai CO 1,58%, HC 91 ppm, CO2 12,2% dan O2 3,71%,
