Abstract

A system for fuel and thermal management of fuel delivered to an engine is disclosed. The system includes a supply of fuel in fluid communication with a fuel inlet of the engine, and an oxygen sensor for measuring dissolved oxygen content in the fuel is in fluid communication with the fuel. The fuel is heated by transferring heat from engine oil in a heat exchanger. The temperature of the fuel is controlled by controlling engine oil flow and airflow through another heat exchanger upstream of the fuel/oil heat exchanger on the oil circulation path with engine oil.
