Abstract
Official abstract text for this publication.
Methods and systems are provided for synergizing the benefits of an engine exhaust driven fuel reformer in a hybrid vehicle system. A vehicle controller may hold the engine in a narrow operating range where fuel reformer operation is optimal while using motor and/or CVT adjustments to address transients generated as driver demand varies. The controller may also adjust an operating range of temperatures of the reformer to enable extended fuel reforming even after the engine of the hybrid has been shutdown.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for a hybrid vehicle, comprising: responsive to lower than threshold engine load while an available reformate is lower than a threshold level, raising engine load above the threshold load and charging a system battery using excess engine torque; and reforming a liquid fuel using exhaust energy, the engine operated with the raised engine load until the available reformate is higher than the threshold level. 2. The met…
