Abstract: According to the invention, there is provided seed and plants of the corn variety designated CV644326. The invention thus relates to the plants, seeds and tissue cultures of the variety CV644326, and to methods for producing a corn plant produced by crossing a corn plant of variety CV644326 with itself or with another corn plant, such as a plant of another variety. The invention further relates to corn seeds and plants produced by crossing plants of variety CV644326 with plants of another variety, such as another inbred line. The invention further relates to the inbred and hybrid genetic complements of plants of variety CV644326.

Abstract: Improved internal combustion engine power systems (e.g., those used to generate mechanical or electrical power in vehicular applications) that utilize a reformed alcohol fuel comprising a hydrogen-containing gas mixture, and more particularly, the efficient operation of such engines and power systems are disclosed. Modes of operating the engine power systems that provide faster startup and lower cost and emissions are provided. In various preferred embodiments, the internal combustion engine power systems include dilution of the intake fluid mixture introduced into the combustion chamber or cylinder of the engine using recirculated exhaust gas and/or excess combustion air as the diluent, use of blends of ethanol reformate and unreformed ethanol as fuel and aftertreatment of the exhaust gas discharged from the cylinder using a lean NOx trap.
