Abstract
A vehicle includes an engine, an oil circuit for providing oil to the engine, a fuel supply line, and an air-oil separating unit. The air-oil separating unit is configured to receive aerated oil from the engine via the oil circuit, flow the aerated oil in approximately a helical direction to de-aerate the oil, receive fuel from the fuel supply line, cool the aerated oil with the fuel while the aerated oil flows in the approximately helical direction, causing the fuel to heat, and pass the cooled and de-aerated oil and pass the heated fuel to the engine.
