Internal combustion engine system with temperature based output control

An internal combustion engine system comprising:

• an internal combustion engine;
• a turbocharger configured to discharge compressed air using exhaust gas supplied from the internal combustion engine;
• a flow ratio adjustment device including a branch configured to divide the compressed air received from the turbocharger into first compressed air and second compressed air, the flow ratio adjustment device further including a valve configured to adjust a flow rate of the first compressed air and a flow rate of the second compressed air;
• a reformer configured to receive the first compressed air and fuel gas and discharge first gas including heat and hydrogen generated as a result of an exothermic reaction between the first compressed air and the fuel gas;
• a junction configured to receive the first gas from the reformer and receive the second compressed air from the valve to generate second gas including the first gas and the second compressed air;
• an air-fuel mixture generator configured to receive the second gas and receive the fuel gas to generate an air-fuel mixture including the second gas and the fuel gas;
• a temperature sensor configured to measure a temperature of the air-fuel mixture;
• and
• a controller configured to output, to the flow ratio adjustment device, a control signal for determining a ratio of the flow rate of the first compressed air supplied to the reformer based on the temperature of the air-fuel mixture.
