Active and passive prechamber assisted engine combustion: simultaneous 50kHz formaldehyde PLIF and OH* visualization [PDF]
Combustion and Flame, 2023 Prechamber-assisted internal combustion engines allow lean limit extension by replacing the spark plug with multiple, high-temperature, radical-rich jets that entrain and ignite the main chamber charge. This work reports the first investigation of active

Prechamber Initiation of Gaseous Detonation in a Channel
Combustion Science and Technology, 2016ABSTRACTDeflagration-to-detonation transition in propane-butane-oxygen mixtures, in an open channel with a circular cross section with a diameter of 3 mm, was investigated experimentally. Detonation initiation was carried out by burning the mixture in the prechamber connected to the channel.

SRC - II Combustion in Prechamber Diesel
SAE Technical Paper Series, 1984<div class="htmlview paragraph">A single cylinder water cooled prechamber diesel engine was used to evaluate SRC-II coal derived fuel with respect to performance and emissions. SRC-II could only be burnt in blend with diesel fuel. Changes of characteristics were shown in relation to SRC-II blend ratio.

The Effects of Fluid Motions on Combustion in a Prechamber Bomb
SAE Technical Paper Series, 1976<div class="htmlview paragraph">A two-chamber bomb was used to investigate the effect of fluid motions on combustion characteristics, in particular exhaust emissions. Variations in prechamber volume, connecting orifice geometry, air-fuel charge stratification, and initial turbulence of the charge were examined. Tests were run over a wide air-fuel
