We conducted airflow analysis within the engine cylinder from the intake manifold to the inside of the cylinder.
SuperCartesian: In the analysis of airflow within the engine cylinder, we accurately represented the intake manifold and valve shapes, and conducted airflow analysis from the intake manifold to inside the engine cylinder. When predicting the performance of an internal combustion engine, it is crucial to understand the airflow characteristics of the mixture being delivered into the cylinder. These airflow characteristics are significantly influenced by the shapes of the intake manifold and valves, which in turn affect combustion efficiency. For more details, please download the catalog.

basic information
【Analysis】 - Among the engine components, the cylinder, intake valve, and intake pipe were modeled. - The mixture drawn in from the intake valve at the top of the cylinder is expelled to the lower part of the cylinder. - These components, which have complex curved surfaces, were modeled using the SuperCartesian method. - A smooth shape was achieved. - Cylinder inner diameter: 50mm, intake pipe inner diameter: 15mm. - Total grid count is 94 (X) × 98 (Y) × 106 (Z) = 976,472. 【Analysis Results】 - Results are displayed as cross-sectional views of wind speed distribution and streamlines. - The intake collides with the valve and spreads into the cylinder, but does not diffuse uniformly. - The flow is biased in the axial direction of the intake pipe within the cylinder, with some flowing along the cylinder wall. - Others flow towards the lower part of the cylinder while swirling complexly. - It is predicted that the flow will change depending on the shape of the intake pipe and valve. - By modeling with the SuperCartesian method, many analysis cases can be examined. ● For more details, please contact us or download the catalog.
