Abstract

PURPOSE:To enable to prevent the fluctuation of air to fuel ratio by a method wherein the fuel injection control is effected by the combined output of a number of revolution, a suction pressure and the opening degree of a choke valve without utilizing a flow meter upon high load and high revolution. CONSTITUTION:Upon the high load and high revolution, an air stream B is striking the measurement board 21 of the flow meter 4 obliquely and the pushing and opening force thereof is reduced, therefore, the increasing amount of an output voltage U of a potentiometer 22 with respect to the amount Q of suction air is reduced, however, a proper maximum value U1 which is in the relation of a linear proportion before the reduction is inputted into a standard setting circuit 16 as a set value. Before the output voltage U is arriving at the value U1, an operation circuit 11 is operated by the output voltage U, and the signals of sensors 9, 10 for the number of revolution and the choke valve and whereby proper fuel in accordance with the amount of the suction air may be injected. When the voltage is arrived at U1, the first fuel injection control system 8 is cut off by a comparating circuit 17 and a switching circuit 18 while a map control is effected by the operation circuit 14 in the second control system 12 based on the signals of sensors 9, 13 for the number of revolution and the suction pressure and the standard value U1, and thus the proper amount of the fuel may be injected.
