Abstract: This invention concerns an engine fuel-oil heat exchange system for an engine (10) having a first fuel line (30) for delivery of fuel to an engine combustor (16) and a second fuel line (32) for delivery of fuel to ancillary engine equipment. The heat exchange system has a first heat exchanger (34) for transfer of heat from an engine oil system to the first fuel line (30) and a second heat exchanger (40) for transfer of heat from the engine oil system to the second fuel line (32). A control valve (46) is provided for selective control of the oil flow (48) from the engine oil system to the first (30) and second (32) heat exchangers.[FIG. 2]
