ABSTRACT:
A thermal load control assembly for a fuel injector includes a rail inlet port, a cooling inlet port and a fuel drain port. A leakage path channels leaked fuel originating from the rail inlet port to the fuel drain port. A cooling path channels fuel originating from the cooling inlet port to the fuel drain port. A fuel system using a thermal load control assembly includes a single fuel tank that supplies fuel to the rail inlet port and the cooling inlet port of a plurality of fuel injectors and collect fuel from the fuel drain port of the plurality of fuel injectors.
