Abstract
A combustion engine for combustion of an air-fuel mixture containing air and fuel, comprising at least one temperature adjusting means for cooling or heating the air, fuel, and/or air-fuel mixture and a control unit configured to determine the methane number and/or hydrogen content of the fuel and/or air-fuel mixture, wherein the control unit is configured to control a temperature of the air, fuel and/or air-fuel mixture based on the determined methane number and/or hydrogen content by controlling the at least one temperature adjusting means.
Claims20
A system, comprising:
- a controller of a combustion engine, wherein the controller is configured to:
- determine a knock value of a fluid flow supplied to a combustion chamber of the combustion engine, wherein the fluid flow comprises at least one fuel, and the knock value varies at least due to variations in a fuel composition of the at least one fuel;
- and
- control at least one temperature adjuster to change a temperature of the fluid flow in response to variations in the knock value caused by the variations in the fuel composition of the at least one fuel.
A method, comprising:
- determining a knock value of a fluid flow supplied to a combustion chamber of a combustion engine via a controller, wherein the fluid flow comprises at least one fuel, and the knock value varies at least due to variations in a fuel composition of the at least one fuel;
- and
- controlling at least one temperature adjuster via the controller to change a temperature of the fluid flow in response to variations in the knock value caused by the variations in the fuel composition of the at least one fuel.
A system, comprising:
- a controller of a combustion engine, wherein the controller is configured to:
- determine a knock value of a fluid flow supplied to a combustion chamber of the combustion engine, wherein the fluid flow comprises at least one fuel, and the knock value varies at least due to variations in a fuel composition of the at least one fuel;
- and
- control at least one temperature adjuster to change a temperature of the fluid flow in response to variations in the knock value, wherein the at least one temperature adjuster is coupled to a fuel flow path of the at least one fuel and/or an air-fuel mixture flow path of an air-fuel mixture of the at least one fuel and air.
