Filed: 1984-05-14
Abstract: PURPOSE:To improve stability of combustion control during changing-over by performing the fuel change-over operation for two flow amount control systems of an auxiliary fuel and a battery surplus fuel by one sequence instruction. CONSTITUTION:When a fuel change-over instruction is generated, the flow amount set value presently given to an auxiliary fuel flow amount controller 13 is given to a battery surplus fuel controller 14. Said signal is outputted to the first ratio meter 30 at a speed, for which a process and a response time of two flow amount control systems are taken into consideration by a change rate limiter 19 for giving the value converted into a battery surplus fuel flow amount according to a heat value as the set value of the controller 14. The controller 14 outputs a valve opening operation signal to a battery surplus fuel flow regulating valve 9. The battery surplus fuel flow amount signal becomes a feed-back signal of the controller 14 for being inputted to the second ratio meter 21 while being outputted to a subtractor 22 as the value converted into an auxiliary fuel for performing a valve operation in the direction to decrease the auxiliary fuel. Thereby, the auxiliary fuel can be changed over into the battery surplus fuel without changing the heat value.
