Resumo(s)
Syngas, a renewable fuel primarily composed of hydrogen and carbon monoxide, is emerging as a viable alternative to conventional fossil fuels in internal combustion engines (ICEs).
Obtained mainly through the gasification of biomass and organic waste, syngas offers
significant environmental benefits but also presents challenges due to its lower heating
value and variable composition. This review establishes recent advances in understanding
syngas combustion, chemical kinetics, and practical applications in spark-ignition (SI)
and compression-ignition (CI) engines. Variability in syngas composition, dependent on
feedstock and gasification conditions, strongly influences ignition behavior, flame stability,
and emissions, demanding detailed kinetic models and adaptive engine control strategies.
In SI engines, syngas can replace up to 100% of conventional fuel, typically at 20–30% reduced power output. CI engines generally require a pilot fuel representing 10–20% of total
energy to start combustion, favoring dual-fuel (DF) operation for efficiency and emissions
control. This work underlines the need to integrate advanced modelling approaches with
experimental insights to optimize performance and meet emission targets. By addressing
challenges of fuel variability and engine adaptation, syngas reveals promising potential as
a clean fuel for future sustainable power generation and transport applications.
