Abstract:

Methods and systems for efficiently utilizing a fuel heating system incorporating an exhaust gas recirculation (“EGR”) stream and an EGR cooling system are disclosed. Waste heat energy in an exhaust gas recirculation stream of an engine system is used to heat the fuel being fed to the combustion chambers of the engine. A conventional EGR cooler can be replaced with a fuel heat exchanger/EGR cooler. Utilizing these components allows fuel heating to be accomplished simultaneously with partial EGR gas cooling by using waste EGR heat. This reduces the heat rejection requirement of the engine coolant and also reduces the electrical power requirements of the fuel heater.
