Commercial transportation fuels are complex mixtures containing hundreds or thousands of chemical components, whose composition has evolved considerably during the past 100 years. In conjunction with concurrent engine advancements, automotive fuel composition has been fine-tuned to balance efficiency and power demands while minimizing emissions. Pollutant emissions from internal combustion engi...

Hydrogen is seen as one of the important energy carriers of the future with potential to reduce local as well as global warming. The main by-product of the combustion of hydrogen in air is water vapor and trace quantities of oxides of nitrogen. An experiment was conducted to study the impact of hydrogen/natural gas blends on performance, thermodynamic efficiency and exhaust gas emissions in ...

Perkembangan teknologi dan industri yang semakin pesat berbanding terbalik dengan cadangan sumber bahan bakar fosil menipis. Hal ini mendorong dilakukannya penelitian untuk mengoptimalkan penggunaan mengurangi ketergantungan akan bakar, khususnya solar. Berdasarkan pemikiran itu, maka dilakukan pengujian mesin diesel Yanmar TF 155 H-Di menggunakan ganda (dual fuel) solar + LPG. LPG digunakan ad...

In diesel engines, it is difficult to reduce both smoke and NOx simultaneously. An experimental study was conducted to determine the performance and exhaust emission characteristics of a commercial single cylinder, natural aspirated, air cooled DI diesel engine. The system was modified to work on either dual fuel or diesel alone. The objective of this work is to investigate the possibility of d...
