“…DFX was found to increase the burning speed due to its oxygen component, and thus provide higher burning temperature and reduce the HC amount. One can see that there is a reasonable compatibility between the effective efficiency obtained within this study and the other research results [9,[22][23][24][25].…”

Current study uses DieselFX (DFX) additive to increase the cetane number of the diesel fuel used in compression-ignition (CI) engines, reduce carbon monoxide (CO) and hydrocarbon (HC) emissions, and improve engine performance. In this respect, the effects of the additive used in diesel engines were analyzed. A Katana brand, KM 178 FE model, single-cylinder, air-cooled engine was started at a constant engine speed with different loads for the experiments. By adding the additive in 1% and 2% ratios the cetane number was increased to 62 and 75, respectively, furthermore at 3% and 5% additive ratios the cetane number value reached over 76. In result of the experiments, DFX2 offers 12.24% increase on efficiency compared to the diesel fuel and 6.87% increase in specific fuel consumption. As for the emission values, with the use of DFX5 44.23% reduction in HC emission and 50% reduction on average in CO emission was observed at 3000W load compared to additive-free diesel fuel. Moreover, 37.84% increase was observed in carbon dioxide (CO2) emission at 3000W engine load for DFX2 whereas 52.11% increase was observed in nitrogen oxide (NOx) emission for DFX5.

Populasi kendaraan di indonesia, dari tahun ke tahun selalu mengalami peningkatan, hal ini berdampak pada konsumsi bahan bakar minyak yang terus bertambah pula, pengurangan konsumsi bahan bakar pada kendaraan dapat dilakukan dengan metode eco driving, salah satu metode dalam eco driving yang paling mudah diterapkan adalah pengaturan kecepatan, posisi roda gigi, dan pemilihan jenis Transmisi yang tepat. Fokus penelitian dengan melakukan analisis terhadap hasil perhitungan konsumsi bahan bakar kendaraan bus dengan variasi dua jenis transmisi model transmisi, untuk mengetahui pola pengendaraan yang rendah konsumsi bahan bakar dan jenis transmisi yang terbaik dari dua transmisi. Hasil yang diperoleh dari penelitian ini, konsumsi bahan bakar bus bus akan terus menurun pada 1000-1300 rpm, namun akan naik kembali secara perlahan pada 1400-2300 rpm, sedangkan kenaikan kecepatan berbanding lurus dengan pertambahan putaran mesin, transmisi tipe MB GO190 adalah transmisi yang paling baik diantara ketiga transmisi lainya karena selisih antara tingkat rasio dalam transmisi ini tidak terlalu jauh sehingga bahan bakar yang terbuang akibat jeda loses traksi pada transmisi ini yang sedikit dan akselerasi kendaraan yang halus dan cepat.

In order to solve issues concerning performance induction and in-cylinder heat accumulation of a certain heavy-duty diesel engine in a plateau environment, working state parameters and performance indexes of diesel engine are calculated and optimized using the method of artificial neural network and genetic algorithm cycle multi-objective optimization. First, with an established diesel engine simulation model and an orthogonal experimental method, the influence rule of five performance indexes affected by five working state parameters are calculated and analyzed. Results indicate the first four of five working state parameters have a more prominent influence on those five performance indexes. Subsequently, further calculation generates correspondences among four working state parameters and five performance indexes with the method of radial basis function neural network. The predicted value of the trained neural network matches well with the original one. The approach can fulfill serialization of discrete working state parameters and performance indexes to facilitate subsequent analysis and optimization. Next, we came up with a new algorithm named RBFNN & GACMOO, which can calculate the optimal working state parameters and the corresponding performance indexes of the diesel engine working at 3700 m altitude. At last, the bench test of the diesel engine in a plateau environment is employed to verify accuracy of the optimized results and the effectiveness of the algorithm. The research first combined the method of artificial neural network and genetic algorithm to specify the optimal working state parameters of the diesel engine at high altitudes by focusing on engine power, torque and heat dissipation, which is of great significance for improving both performance and working reliability of heavy-duty diesel engine working in plateau environment.
