Abstract
A fluid control system for an engine may include an air pathway to carry air to the engine, a fuel pathway to carry a fuel to the engine, and at least one temperature control device to control temperatures of the air and the fuel. The temperature control device maintains the air and the fuel at a temperature based on a target air-fuel ratio and a target volume of the air and the fuel.
Claims20
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.

A method of controlling fluid temperature within an engine, comprising:
- determining a target air-fuel ratio based on at least one parameter of an operation of the engine;
- with a first sensor, detecting a temperature of air introduced into the engine;
- with a second sensor, detecting a temperature of a fuel introduced into the engine;
- with a controller, determining a target temperature of the air and a target temperature of the fuel to meet the target air-fuel ratio;
- with a first control device, adjusting the temperature of the air before introduction into a combustion chamber of the engine to the target air-fuel ratio and a target volume of the air and the fuel by heating the air and cooling the air based at least in part on feedback from at least one of the first sensor and the second sensor defining a deviation from the target air-fuel ratio and the target volume of the air;
- and
- with a second control device, adjusting the temperature of the fuel before introduction into the combustion chamber of the engine to the target air-fuel ratio and the target volume of the air and the fuel by heating the fuel and cooling the fuel based at least in part on feedback from at least one of the first sensor and the second sensor defining a deviation from the target air-fuel ratio and the target volume of the fuel.
