DR-640 V0.2 Twin-Rotor Rotary Engine

You PROJECT: DR-640 V0.2 UNITS: millimeters MODEL TYPE: fully parametric mechanical assembly ENGINE TYPE: 2-rotor headless rotary-disc petrol ICE ORIENTATION: X = main shaft/engine longitudinal axis Y = engine width Z = vertical Origin = geometric center of complete rotary core ================================================== 01 — COMPLETE ENGINE ASSEMBLY ================================================== Create a detailed engineering cutaway assembly. Maximum complete engine envelope excluding gearbox, exhaust pipes, radiator and airbox: X length = 340 Y width = 280 Z height = 290 Bare rotary-core target envelope: X length = 280 Y width = 180 Z height = 180 Main shaft centerline: X axis Y = 0 Z = 0 Architecture along X: LEFT END COVER LEFT MAIN BEARING LEFT SEAL CARRIER LEFT STATIONARY WORKING PLATE ROTOR A CENTRAL WORKING/SEAL STRUCTURE ROTOR B RIGHT STATIONARY WORKING PLATE RIGHT SEAL CARRIER RIGHT MAIN BEARING RIGHT END COVER Use two completely circular concentric rotors. Rotor A and Rotor B rotate about exactly the same X axis. Each rotor contains two balanced blind curved-oval working cavities. Total working cavities = 4. Target effective engine displacement = 640 cc. Target swept displacement per chamber = 160 cc. Target compression ratio = 10.0:1. Required chamber-volume targets: Vmax = 177.78 cc Vmin = 17.78 cc Vswept = 160.00 cc The complete assembly must include: housing 2 rotors shaft main bearings stationary working plates replaceable hot inserts face-seal carriers water jackets oil galleries 4 rotor oil jets wet sump mechanical oil-pump mounting coolant-pump mounting intake plenum carburetor flange fixed intake ports fixed exhaust ports spark-plug bosses end covers fasteners alignment dowels Generate external, transparent and full cutaway views.
