1. A fluid control system for an engine comprising:
an air pathway to carry air to the engine;
a fuel pathway to carry a fuel to the engine;
a first temperature control device to control a temperature of the air; and
a second temperature control device to control a temperature of the fuel, wherein the first temperature control device maintains the air at a temperature of a target air-fuel ratio and a target volume of the air by adjusting the temperature of the air by heating the air and cooling the air based at least in part on feedback from at least one first sensor defining a deviation from the target air-fuel ratio and the target volume of the air, and
wherein the second temperature control device maintains the fuel at a temperature of the target air-fuel ratio and a target volume of the fuel by adjusting the temperature of the fuel by heating the fuel and cooling the fuel based at least in part on feedback from the at least one second sensor different from the at least one first sensor defining a deviation from the target air-fuel ratio and the target volume of the fuel.
