“…Jamrozik, Tutak, Kociszewski and Sosnowski [5] also presented their results for a numerical simulation of two-stage combustion in SI engine with prechamber, using KIVA-3V code. Results from the cooling process analysis for a torch ignition system have been presented by Moreira [6], using Ansys Fluent software. Other approaches done with 1-D/0-D software have also been developed.…”

Torch ignition systems in spark-ignition engines represents an interesting option in the efforts to reduce pollutants emission and specific fuel consumption. Based on this idea, this paper presents a 3D model of a prechamber created for a spark-ignition engine and focuses on the numerical analysis of the fluid flow inside the modified chamber. This kind of analysis is very important once it allowed evaluating aspects like turbulence parameters, pressure inside the chamber and prechamber, fluid recirculation and a possible prechamber’s geometry for the engine. The studies were done in a four valve Single Cylinder Research Engine – SCRE. For the numerical modeling and fluid flow investigation was used STAR-CD software. Results show higher values of tumble ratio and kinetic energy with the prechamber.
