Abstract:
Syngas (Synthetic Gas), also known as producer gas or wood gas, is a gaseous fuel which could be produced by the gasification of biomass. It is mainly composed of hydrogen and carbon monoxide with a smaller share of methane, all diluted by nitrogen and carbon dioxide. Although it contains carbon in its composition, it is considered as a low or zero carbon fuel as soon as it is made from biomass, which makes it a strong candidate for reducing the global warming impact of combustion engines. This work focuses on the combustion development and performances of a Spark-Ignition engine, fuelled with a syngas enriched with ammonia, from a nitrogen-rich sample, typical of ammonia-enriched sewage sludge. Results show that, by replacing part of the syngas by ammonia, even as expected the combustion development is slowed down, the indicated work increases. Last exhaust emissions measurement shows a decrease in CO and CO2 as a function of ammonia addition in the fuel but a slight increase of NOx.
