US4802931: High energy product rare earth-iron magnet alloys
Croat; John J. , Sterling Heights, MI
General Motors Corporation, Detroit, MI
Magnetically hard compositions having high values of coercivity,
remanence and energy product contain rare earth elements, transition
metal elements and boron in suitable proportions. The preferred
rare earth elements are neodymium and praseodymium, and the
preferred transition metal element is iron. The magnetic alloys
have characteristic very finely crystalline microstructures.
US4496395: High coercivity rare earth-iron magnets
Croat; John J. , Sterling Heights, MI
General Motors Corporation, Detroit, MI
Ferromagnetic compositions having intrinsic magnetic coercivities
at room temperature of at least 1,000 Oersteds are formed by
the controlled quench of molten rare earth-transition metal
alloys. Hard magnets may be inexpensively formed from the lower
atomic weight lanthanide elements and iron.
US4770723: Magnetic materials and permanent magnets
Sagawa; Masato , Nagaokakyo, Japan
Fujimura; Setsuo , Kyoto, Japan
Matsuura; Yutaka , Ibaraki, Japan
Sumitomo Special Metals Co., Ltd., Osaka, Japan
Magnetic materials comprising Fe, B and R (rare earth elements)
having a major phase of Fe--B--R intermetallic compound(s) of
tetragonal system, and sintered anisotropic permanent magnets
consisting essentially of, by atomic percent, 8-30% R (at least
one of rare earth elements inclusive of Y), 2-28% B and the
balance being Fe with impurities. Those may contain additional
elements M (Ti, Ni, Bi, V, Nb, Ta, Cr, Mo, W, Mn, Al, Sb, Ge,
Sn, Zr, Hf) providing Fe--B--R--M type materials and magnets.
While theoretically, magnetically polarizing hydrocarbon chains might give an increase in efficiency to combustion, fracturing these chains, their claim, won't. IMHO, the polarization would have to occur after combination with air, but before combustion (inside the intake manifold or injector body), to yield any possible significant benefit. It'd be more difficult and expensive to implement then any possible cost saving, which is why the automakers haven't done it.
