The prompt
Create a parametric methane generator engine assembly concept, focused on the intake side and supporting subsystems. Design a compact stationary gas engine/generator layout with a biomimetic hybrid low-loss + swirl intake architecture. MAIN REQUIREMENTS: - Overall concept: a complete methane engine module suitable for a stationary generator set. - Intake manifold: tree-like branching geometry with smooth progressive transitions. - Runner length: 200 mm. - Runner diameter: 35.6 mm. - Plenum volume: 0.50 L. - Branch angle: 20 degrees. - Bend radius: 45 mm minimum. - Wall thickness: 3 mm. - Internal surface: very smooth. - Add a removable swirl insert at the end of each intake runner. - Swirl insert length: 25 mm. - Swirl twist: 35 degrees. - Swirl blockage ratio: low, about 8%. ENGINE MODULES TO INCLUDE: - Cylinder head block placeholder. - Intake manifold. - Exhaust manifold placeholder. - Generator coupling placeholder. - Cooling jacket placeholder. - Base frame / skid placeholder. DESIGN GOAL: Reduce pressure losses, keep airflow distribution uniform, and create controlled swirl near the cylinder entry for methane-air mixing. STYLE: Mechanical and precise, not artistic. Parametric CAD model with editable dimensions. Use clean engineering geometry and realistic part separation for assembly. Export-ready for STEP or STL.
