A method for fabricating a MOSFET is provided. The new variety is a Trifolium, typically produced as an ornamental plant. A heating element is coupled to the housing so the heating element may heat the mold. A clearance varying device varies a magnitude of a clearance between the opposite and confronting surfaces of the stator and the rotor. In other embodiments, the open valve fuel injector may be used in conjunction with direct injection of the primary fuel or the anti-knock fuel. In use, a plurality of parameters associated with a product or service is identified.
