  • Fuel injection control method of fuel reformer and fuel reforming system
    Patent number: 10619602
    Abstract: A fuel injection control method includes measuring EGR (exhaust gas recirculation) rate through a CO2 sensor measuring the amount of CO2 entering the intake side of the engine, setting an optimum SCR (Steam to Carbon Ratio) value based on the measured EGR rate, calculating the amount of steam supplied to the engine based on the measured EGR rate, calculating an actual SCR value by the ratio of the steam amount and the carbon component of the fuel supplied to the engine, comparing the actual SCR value with the optimum SCR value, calculating the SCR difference value by subtracting the optimum SCR value from the actual SCR value if the actual SCR value is greater than the optimum SCR value, calculating an additional fuel amount to be added based on the SCR difference value, and injecting fuel to the fuel reformer based on the calculated additional fuel amount.
