Abstract
An energy recovery system for a diesel electric locomotive is disclosed. The energy recovery system captures and stores the waste heat generated by the diesel engine of the diesel electric locomotive for use at a remote location at a later time. The energy recovery system also converts the electricity generated by the diesel electric locomotive during dynamic braking into heat, and captures and stores this heat for use at a remote location at a later time.
Claims9
An energy recovery system for a locomotive mounted on wheels, comprising:
- an internal combustion engine located on a wheeled locomotive which serves as the primary source of power for said locomotive;
- an electric dynamo which is mechanically powered by said internal combustion engine;
- an electric motor which is electrically powered by said dynamo, which electric motor serves to propel the locomotive by rotating at least one of the wheels of said locomotive, and which electric motor operates as a dynamo to produce electricity during dynamic braking of said locomotive;
- and
- energy recovery tank means containing a heat storage fluid for capturing and storing waste heat energy generated by said internal combustion engine and electrical energy generated by said electric motor for use at a remote location at a later time.
