Abstract
A fuel heating system for a machine is disclosed. The fuel heating system may have a fuel tank, and a fuel supply line fluidly connected to the fuel tank, to a first engine, and to a second engine. The fuel heating system may also have a first heat exchanger fluidly connected to the first engine to transfer heat from the first engine to fuel in the fuel supply line. In addition, the fuel heating system may have a second heat exchanger fluidly connected to transfer heat from the second engine to fuel in the fuel supply line.
Claims20
A fuel heating system, comprising:
- a fuel tank;
- a fuel supply line fluidly connected to the fuel tank, to a first engine, and to a second engine;
- a first heat exchanger fluidly connected to transfer heat from the first engine to fuel in the fuel supply line;
- and
- a second heat exchanger fluidly connected to transfer heat from the second engine to fuel in the fuel supply line.
2 more elements
A method of heating fuel, comprising:
- circulating coolant from a first engine through a first heat exchanger;
- circulating coolant from a second engine through a second heat exchanger;
- selectively directing fuel through the first and second heat exchangers to at least one of the first and second engines.
A locomotive comprising:
- a platform;
- a plurality of wheels configured to support the platform;
- a fuel tank mounted to the platform;
- a first engine mounted to the platform;
- a second engine mounted on the platform;
- a fuel supply line fluidly connecting the fuel tank to the first engine and to the second engine;
- a fuel filter in the fuel supply line upstream of the first and second engines;
- a fuel valve configured to direct a desired amount of fuel to the first engine and the second engine;
- a first heat exchanger fluidly connected to transfer heat from the first engine to fuel in the fuel supply line;
- a second heat exchanger fluidly connected to transfer heat from the second engine to fuel in the fuel supply line;
- a first thermostatic valve to control a flow rate of coolant from the first engine through the first heat exchanger;
- and
- a second thermostatic valve to control a flow rate of coolant from the second engine through the second heat exchanger.
