| Combustion characteristics of a swirl chamber type diesel engine Gyeung Ho Choi/Jae Cheon Lee/Tae Yun Kwon/Chang Uk Ha/Jong Soon Lee/Yon Jong Chung/Yong Hoon Chang/Sung Bin Han
The Journal of Mechanical Science and Technology, vol. 23, no. 12, pp.3385-3392, 2009
Abstract : A numerical model that utilizes Computational Fluid Dynamics (CFD) techniques is simulated for the analysis of a
swirl chamber type diesel engine. This research also reveals the effects of swirl chamber passage hole geometry on the
combustion characteristics of a swirl chamber type diesel engine depending on the shape, angle, and area of the jet
passage. Turbulence kinetic energy is generated by compound effects of the pressure, heat release, NOx concentrations,
and soot concentrations. Results show that combustion characteristics are affected by the passage hole areas and the
passage hole inclination angles.
