A review on the effects of ethanol/gasoline fuel blends on NOX emissions in spark-ignition engines [PDF]
Biofuel Research Journal, 2021 Ethanol can be used as an alternative fuel for spark-ignition (SI) engines to increase the octane number and oxygen content of ethanol/gasoline blends, thereby reducing dependence on fossil fuels and the exhaust emissions of incomplete combustion ...

Modeling of a turbocharged SI engine [PDF]
Annual Reviews in Control, 2002 Turbocharged SI engines are a major possibility in the current trend of down-sized engines with preserved drivability performance. Considering control and supervision it is favorable to have a mean value model to be used e.g. in observer design. Such models of turbo engines are similar to those of naturally aspirated engines, but there are some special

NOx emissions from ammonia-hydrogen fueled SI Engines
Nihon Kikai Gakkai ronbunshu, 2020 Ammonia has been suggested as a potential carbon-free fuel for spark ignition reciprocating engines. As ammonia is a nitrogen compound, nitrogen oxide (NOx) emissions are important subjects to study.
