Numerical investigation of the swirl combustion chamber for the Opposed-Piston Compression-Ignition engine

Rafał Pyszczek , Jakub Kalke , Paweł Mazuro


The possibility of achieving high thermodynamic efficiency brings opposed-piston (OP) engines back into interest of research centers. IF made as 2-stroke, the possibility of unidirectional scavenging arises together with lower engine cost due to removal of unnecessary parts like like camshafts or poppet valves. Unfortunately, in the OP design the injection is perpendicular to cylinder axis, which is ineffective with conventional diesel injectors. Following article presents a proposed solution to this particular problem using an externally-attached swirl combustion chamber. The quantitative assessment of ability to meet the design expectations was performed in AVL Fire software. Authors describe the CFD model and injector used for simulations. Contour plots and charts are given to compare the results. A variety of geometrical cases was analyzed
