Heat storage device for an engine

Abstract

A heat recovery system for an engine is disclosed herein utilizing a heat storage unit configured to store waste exhaust heat for subsequent use on engine starts in various systems. In this way, improved system operation can be obtained by re-using such waste heat.

Description

BACKGROUND AND SUMMARY[0001]Vehicles may recover exhaust heat for transfer to various other systems in an internal combustion engine.[0002]The inventors herein have recognized various issues with such systems in that the available packaging space for storing waste heat is limited, and further suitable coordination among various vehicle components is lacking. As such, one example approach to address the above issues is, claim 1.[0003]It should be understood that the summary above is provided to introduce in simplified form a selection of concepts that are further described in the detailed description. It is not meant to identify key or essential features of the claimed subject matter, the scope of which is defined uniquely by the claims that follow the detailed description. Furthermore, the claimed subject matter is not limited to implementations that solve any disadvantages noted above or in any part of this disclosure.BRIEF DESCRIPTION OF THE DRAWINGS[0004]FIGS. 1A-1B schematically...
