ABSTRAK

Cadangan minyak bumi semakin lama semakin berkurang sehingga banyak penelitian yang dilakukan untuk menyelesaikan permasalahan ini seperti memodifikasi diesel menjadi dual fuel. Sistem kerja dari dual fuel adalah memasukkan CNG kedalam ruang bakar bersamaan dengan udara pada saat langkah hisap di intake manifold dan akan ikut terbakar dengan solar sebagai pematiknya. Untuk mengkonversi solar ke CNG perlu dihitung nilai kalor dari masing masing bahan bakar tersebut. Metode yang dapat digunakan adalah berdasarkan GPA Standard dan komposisi atom penyusun CNG. Setelah didapatkan nilai kalor perlu dianalisa nilai dari Low Explosive Limit dan High Explotion Limit dari CNG untuk mengetahui apakah bahan bakar gas dan oksigen cukup untuk melakukan pembakaran. Spesifikasi dari komponen komponen yang diperlukan dalam konverter kit ini disesuaikan dengan standar spesifikasi untuk dioperasikan dengan CNG. Pengujian alat ini dapat dilakukan tanpa mengurangi bahan bakar solar dan kemudian ditambahkan dengan CNG. Berdasarkan hasil pengujian CNG mampu mensubtitusi kebutuhan solar sampai 75.


ABSTRACT

The resource of fossil fuels are going to be decreased immediately therefore many research has been used to solve this problem such as the modification of diesel engine to dual fuel. Dual fuel system is setting the gas into the combustion chamber conformity with the air when the intake stroke by mixing both of CNG and air in intake manifold. To compare the diesel fuel and CNG consumption it needs to know the heating value of each fuels. The methods of heating value calculation are GPA Standard and atomic composition of CNG. After obtaining the heating value the value of Low Explosive Limit and High Explotion Limit of CNG are analysed to find out whether the fuel and oxygen is being covered for combustion. The specification of Converter Kit components is determined by the standard of CNG usage specification. For experiments the dieel fuel of engine doesnt need to be substracted while the CNG can be added. Based on the results of experiments the diesel fuel can be subtituted by CNG upon 75
