Abstract
Official abstract text for this publication.
Systems and methods for operating an engine that includes an exhaust gas heat recovery system are described. The system may reduce engine warm-up time and increase an amount of time an engine of a hybrid vehicle is deactivated while the hybrid vehicle is powered by a motor. In one example, a phase change material selectively stores and releases exhaust gas energy from and engine to improve vehicle operation.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operating an engine, comprising: operating an engine; transferring engine exhaust gas heat energy from the engine to a thermal energy storage device via an engine exhaust gas heat exchanger; and transferring heat energy from the thermal energy storage device to a passenger cabin heater core while the engine has stopped rotating. 2. The method of claim 1 , further comprising adjusting a position of a bypass valve…
