Abstract: A system for rapidly heating a vehicle engine when the engine is below a pre-determined temperature allows for improved fuel efficiency after a vehicle cold-start. The system includes an organic Rankine cycle (ORC) loop having a two-phase ORC fluid traveling circuitously through a conduit. The ORC fluid is vaporized by a power electronics cooling device and by an evaporator in thermal communication with exhaust waste heat. The vaporized ORC fluid is passed through an expander to generate electrical power. When the vehicle engine is below the pre-determined temperature, heat from the vaporized ORC fluid is transferred directly or indirectly to the engine. When the vehicle engine is at or above the pre-determined temperature, heat from the vaporized ORC fluid is instead transferred to an alternate heat sink.
