Experimental observation of the combustion modes based on a novel multistage pre-chamber turbulent jet ignition (TJI) system

Physics of Fluids, 2023
Transient jet flame propagation under newly proposed multistage pre-chambers is studied in a constant-volume combustion chamber with a high-speed schlieren photography system. Various combustion behaviors, including the flame tip velocity, jet emergence timing, projected flame area, pressure, and heat release rate, are investigated under different pre ...

A study of the turbulent jet flow field in a methane fueled turbulent jet ignition (TJI) system

Combustion and Flame, 2017
Abstract This paper analytically and computationally examines the transient jet used to ignite combustible mixtures during Turbulent Jet Ignition (TJI). In TJI the ignition source, which originates in the prechamber, enters through a connecting nozzle into the main chamber as a transient high temperature jet of reacted mixture, reacting mixture and ...

Influence of pre-chamber structure and injection parameters on engine performance and combustion characteristics in a turbulent jet ignition (TJI) engine

Fuel, 2021
Abstract Turbulent jet ignition (TJI) has been proven to effectively improve the burning rate and expand the lean-burn limit of gasoline engines. In this work, based on a single-cylinder engine, injection parameters in the pre-chamber were investigated, combustion characteristics were studied, and pollutant emissions were optimized. Results show that
