Abstract
PURPOSE: To prevent engenderment of after-burning by performing fuel cut right after deceleration even with deceleration at the time of high speed rotation of the engine.
CONSTITUTION: An AND GATE G1 gives input of negative pressure signal b through rotating signal (a) and a delay mechanism D, output of cut signal C1 is given by these coincidences. An AND GATE G2 gives input of negative pressure signal b and rotating signal c, output of cut signal c2, is given by these coincidences. An OR GATE G3 gives input of cut signals c1, c2, output of fuel cut signal fc. The control system made by said constitution cuts fuel supply with a desired time delay when the engine is within the range of the first rotation Ra, and when it is in the second rotation Rc which is higher than the first rotation Ra, the time delay is set to zero, and the fuel supply is able to be cut. Thus, even if the deceleration is done at the time when it is over the second rotation Rc, the fuel cut can be done right after deceleration, and the after-burning can be prevented
