Abstract
A fluid temperature conditioner heats fuel being supplied to a fuel injection system for an engine. During operation of the engine, energy is transferred from engine and stored in a thermal battery which is a part of the fluid temperature conditioner. During cold starting of the engine, the energy is transferred from the thermal battery to the fuel to aid in the starting of the engine.

A fluid temperature conditioner comprising:
- a reservoir tank defining an inner chamber including an upper surface and a lower surface;
- a pump mounted to an exterior surface of the reservoir tank;
- a phase change material within the inner chamber;
- a heat transfer medium within the inner chamber;
- an outlet line extending between the inner chamber and the pump, the outlet line including an outlet line orifice between the phase change material and the upper surface;
- a heater proximate to the outlet line orifice;
- and
- a return line extending between the inner chamber and the pump, the return line including a return line orifice proximate to a portion of the phase change material proximate to the lower surface of the inner chamber;
- wherein the pump is configured to pump the heat transfer medium to and from a vehicle component to be heated.
