Effect of Torch Jet Direction on Combustion and Performance of a Prechamber Spark-Ignition Engine
TL;DR: In this paper, the effect of torch jet direction on the combustion characteristics and engine performances of a spark-ignition engine with each divided chamber having a torch nozzle of different flow direction was examined by changing the torch nozzle area, prechamber volume and air-fuel ratio.
Proceedings ArticleDOI
LDA Measurement of Turbulent Flow in a Motored and Firing Spark-Ignition Engine with a Horizontal Prechamber
TL;DR: In this paper, a laser Doppler anemometer (LDA) is used to measure the mean velocity and turbulence intensity in a spark ignition engine with an unscavenged prechamber connected to a main chamber by a torch nozzle of different area sizes.
Journal ArticleDOI
Combustion analysis with gas temperature diagrams measured in a prechamber spark ignition engine
Hano Ryu,Tsuyoshi Asanuma +1 more
TL;DR: In this article, a more reasonable model of torch combustion in a spark ignition engine with an auxiliary combustion chamber was proposed, where gas temperature diagrams measured under a wide range of air-fuel ratio and torch nozzle diameter were analyzed to determine such combustion characteristics show a reasonable agreement with those estimated from the pressure diagrams.

Numerical Simulation of Two-Dimensional Combustion Process in a Spark Ignition Engine with a Prechamber using k - ε Turbulence Model
Hano Ryu,Tsuyoshi Asanuma +1 more
TL;DR: In this article, two-dimensional combustion processes in a spark ignition engine with and without an unscavenged horizontal prechamber are calculated numerically using a {kappa}-{epsilon} turbulence model, a flame kernel ignition model and an irreversible reaction model to obtain a better understanding of the spatial and temporal distributions of flow and combustion.
