Oznake:
spark ignition engines;renewable fuels;combustion;syngas;natural gas;
Power generation units based on the bio-syngas system face two main challenges due to (i) the possible temporary shortage of primary sources and (ii) the engine power derating associated with the use of low-energy density fuels in combustion engines. In both cases, an external input fuel is provided ...
