Multiple Spark Ignition Approach to Burn Ammonia in a Spark-Ignition Engine: An Optical Study

SAE technical paper series, 2023
The future of the internal combustion (IC) engine relies on carbon-free fuels to mitigate climate change. Ammonia (NH3) is a promising carbon-free fuel, which can be used as an energy carrier for hydrogen (H2) and directly as a combustible fuel inside ...

Limits of compression ratio in spark-ignition combustion with methanol

, 2021
A shift toward a circular and C O 2 -neutral world is required, in which rapid defossilization and lower emissions are realized. A promising alternative fuel that has gained traction is methanol, thanks to its favorable and clean-burning fuel properties ...

Investigations on spark pre-chamber ignition and subsequent turbulent jet main chamber ignition in a novel optically accessible test rig

International Journal of Engine Research, 2021
Turbulent jet ignition (TJI) is a promising strategy to ignite diluted air-fuel mixtures; this is usually generated by igniting a fraction of the mixture inside a small pre-chamber.
