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 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 will present the proposed solution to this particular problem using an externally-attached swirl combustion chamber. The qualitative assessment of ability to meet the design expectations was performed in AVL Fire. The authors describe the CFD model and injector used for simulation. Contour plots and charts are given to compare the results. A variety of geometrical cases were analyzed. The recapitulation gives a critical evaluation of the proposed solution.
