Ammonia (NH 3) energy has emerged as a new international strategy to mitigate climate
change and energy crises because ammonia–hydrogen fuel can effectively overcome the …

This review covers efforts to optimize combustion in spark ignition and compression ignition
engines using pre-chamber ignition systems, with a focus on the fuel used in the pre …

The combustion of hydrogen generates almost no harmful emissions except for nitric oxides
(NO x), which could be effectively eliminated under lean-burn conditions. In particular, the …

Pre-chamber turbulent jet ignition technology is an effective way to optimize the methanol-air
mixture combustion process. A literature survey of structures of currently used pre-chambers …

Pre-chamber spark-ignition (PCSI), either fueled or non-fueled, is a leading concept with the
potential to enable diesel-like efficiency in medium-duty (MD) and heavy-duty (HD) natural …

The pre-chamber combustion concept (PCC) concept shows promises for lean combustion
to achieve improved combustion stability and engine efficiency. The KAUST narrow-throat …

Due to its potential to extend the lean limit or overcome knock-limited conditions on spark-
ignited (SI) engines, the pre-chamber spark-ignition (PCSI) concept has gained attention as …

Hydrogen is a promising future fuel to enable the transition of transportation sector toward
carbon neutrality. The direct utilization of H2 in internal combustion engines (ICEs) faces …

This paper aims to investigate the mechanism of the asymmetric jets of the TJI system. We
analyzed the effects of fuel injection and air flows in pre-chamber and main chamber, initial …

Pre-chamber spark ignition combustion has shown several advantages for its
implementation in engines, mainly related to its capability to achieve stable operation at lean …
