diesel engine 3d model

Create a detailed 3D CAD model of a four-stroke diesel engine with accurate real-world dimensions. Model should include: – Engine block with cylinder bores sized realistically (e.g., bore ~128 mm, stroke ~155 mm for an inline-6 class engine such as Mercedes-Benz OM457). :contentReference[oaicite:0]{index=0} – Six cylinders in inline configuration with correct spacing and crankcase features. – Cylinder head, valves, injectors, fuel rail, intake and exhaust manifolds accurately positioned relative to bores. – Crankshaft with counterweights sized relative to stroke / bore dimensions. – Oil pan, timing cover, and accessory mounts (alternator, water pump, turbocharger inlet / outlet). – Overall engine block dimensions roughly length ~1316 mm, width ~746 mm, height ~1019 mm (based on OM457 dimensions). :contentReference[oaicite:1]{index=1} – Realistic metallic textures, filleted edges, clean topology suitable for CAD export (STEP/OBJ), and neutral lighting on transparent background.
