Abstract
NON-MAGNETIC UNLINED ALUMINUM ENGINE BLOCKS ARE CURRENTLY FEASIBLE IN GASOLINE ENGINES, BUT NOT FOR DIESELS, WHERE PRESSURE LOADINGS AT THE FOR DIESELS, WHERE PRESSURE LOADINGS AT THE NOVEL VENTILATED BAND SEAL APPROACH WILL SOLVE THAT PROBLEM,AND WILL ALSO REDUCE FUEL CONSUMPTION IN ANY PISTON DRIVEN DEVICE. FEATURES INCLUDE: POSITIVE CONTACT FOR LOW LEAKAGE AND DIRT EXCLUSION, A VENTILATED FACE FOR LOW FRICTION AND WEAR, RADICAL COMPLIANCE AND A STATIC BACK SEAL FOR CONFORMANCE TO BORE DISTORTIONS AND TAPER. RESEARCH WILL BE CONDUCTED IN A BLIND CYLINDER WITH A PISTON RING PACK DRIVEN BY AN EXISTING SEALED SLIDER CRANK MECHANISM. A THEORETICAL MODEL WILL BE EMPIRICALLY VERIFIED.
