Gaseous fuel utilisation reduces pollutant emissions and makes energy systems less dependent from oil. Their carbon content is low, which means a reduction in CO2 emissions per unit of energy in comparison with liquid fossil fuels. The use of biogase

Use of biogas containing CH4, H2 and C02 in controlled auto-ignition engines to reduce NOx emissions
The use of biogas in internal combustion engines presents many advantages. Nevertheless, the CO2 content in the fuel negatively affects the combustion process, reducing combustion speed and stability. The presence of hydrogen in the biogas would impr
