Energy recovery system for a mobile machine
First Claim
1. An energy recovery system for a mobile machine having a locomotive and a tender car, comprising:
- a tank located on the tender car and being configured to store a liquid fuel for combustion within a main engine located on the locomotive;
a fuel delivery circuit connecting the tank to the main engine;
an auxiliary engine located on the locomotive; and
a boil-off circuit connecting the tank to the auxiliary engine.

Abstract
The disclosure is directed to an energy recovery system for a mobile machine. The mobile machine may include a locomotive and a tender car. The recovery system may include a tank located on the tender car. The tank may be configured to store a liquid fuel for combustion within a main engine located on the locomotive. The recovery system may also include a fuel delivery circuit connecting the tank to the main engine, and an auxiliary engine located on the locomotive. The auxiliary engine may be selectively connectable to receive gaseous fuel formed in the tank. The energy recovery system may also include a boil-off circuit connecting the tank to the auxiliary engine.

20. A train consist, comprising:
-
a locomotive having; a frame; a main engine mounted to the frame; a plurality of wheels configured to support the frame and driven by the main engine; an auxiliary engine mounted to the frame; and a generator driven by the auxiliary engine; a tender car having a tank configured to store a liquid fuel; a boil-off circuit connecting the tank to the auxiliary engine a fuel delivery circuit connecting the tank to the main engine; an accumulator fluidly connected to the boil-off circuit between the tank and the auxiliary engine and configured to store gaseous fuel formed in the tank; an electrical connection in communication with the generator, the electrical connection configured to transfer electricity generated by the generator to an external load; an inlet valve configured to selectively pass gaseous fuel from the tank to the accumulator when a pressure of the tank exceeds a tank pressure threshold; and an outlet valve configured to selectively pass gaseous fuel from the accumulator toward the auxiliary engine when a pressure of the accumulator exceeds a high pressure threshold.
