PURPOSE:To improve the thermal efficiency and the fuel consumption and stabilize the combustion performance by installing a means for detecting the H2 concentration in reformed gas and a means for correcting and controlling each set value of the rate of feeding fuel and the excessive rate of air in the mixed gas. CONSTITUTION:A temperature sensor 19 is installed in a reformer 4, and an alcohol flow-rate meter 32 is installed in an alcohol passage 7 in the upstream of a check valve 6. The concentration of H2 in the reformed gas is detected on the basis of the detected temperature for catalyst and the amount of feeding alcohol into the reformer 4. A controller 23 corrects each set value of the rate of feeding of alcohol reformed gas and no-reformed gas and the excessive rate of air in the mixed gas, corresponding to the H2 concentration in the reformed gas. Thus, generation of abnormal combustion can be prevented, and stable driving performance cab be obtained at all times. |
