Methods and systems for utilizing waste heat for a hybrid vehicle

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 c...

More Information
Summary: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.
