Abstract Turbulent Jet Ignition is a prechamber initiated combustion system that can replace
the spark plug in a standard spark ignition engine. The nozzle orifice is critical in a turbulent …

Turbulent jet ignition is a pre-chamber ignition enhancement method that produces a
distributed ignition source through the use of a chemically active turbulent jet which can …

An experiment has been developed to investigate the ignition characteristics of ultra-lean
premixed H₂/air mixtures by a supersonic hot jet. The hot jet is generated by combustion of …

Gas engines often utilize a small-volume pre-chamber in which fuel is injected at near
stoichiometric condition to produce a hot turbulent jet which then ignites the lean mixture in …

Turbulent hot-jet ignition (THJI) is an advanced ignition enhancement technology which can
potentially overcome the problem associated with lean burn combustion. The present study …

Detonation initiation is one of the key problems in the application of pulse detonation engine
(PDE). In recent years, the experimental research and numerical simulation results of multi …

Lean combustion is a promising combustion technology that has the potential to improve
engine efficiency while decreasing emissions. One reason why lean combustion has not …

In this study, detonation initiation in supersonic premixed flow is experimentally investigated
using hot jets with different strength. Two types of shock interaction models, B/S …

Jet flow pre-chamber ignition is used to increase the thermal efficiency of lean-burn engines,
