Abstract

The flow field within the cylinder of internal combustion engines is themost important factor controlling the combustion process.  Thus it has a major impact on engine operation. This paper represents the influence of the piston deep bowl eccentricity on the in-cylinder now in a deep-bowl direct injection Chamber during the compression stroke. The eccentricity of the bowl axis is. Varied from. O to 30 mm with a ratio to the piston radius of 0.5 with a diametral ratio of bowl to piston of 0.4. An expression for the squish flow velocity is obtained for the eccentric deep bowl. The influence of the eccentricity on the spatial and temporal distribution of the flow, the squash flow velocity, the tangential swirl velocity of the flow, the velocity vector and contour lines, the swirl center and the swirl intensity is represented .
