<p>PURPOSE:To control a fuel jet quantity with a high accuracy, to prevent a delay of a rise of a revolving speed of an engine, and to reduce an exhaust quantity of an exhaust gas by constituting a titled device so that an output of a heat wire sensor is smoothed appropriately even in case of a transient state of the engine. CONSTITUTION:A capacity of a suction system of a throttle valve 3, a surge tank 4, a suction port 5, etc. exists between a heat wire sensor 2 and a combustion chamber 9. Therefore, when the throttle valve 3 is changed quickly from full-closing to full-opening, an air quantity D absorbed into the combustion chamber 9 and an air quantity C detected at a position of the heat wire sensor 2 do not coincide with each other. On the other hand, the quantity of a fuel jetted into the combustion chamber 9 is determined in accordance with a virtual absorbed air quantity C, therefore, it is excessive with respect to the air quantity D absorbed into the combustion chamber actually. Therefore, in case of a state that a variation rate F of an opening of the throttle valve 3 has exceeded a prescribed value T, overrich or overlean is prevented by smoothing an output of the heat wire sensor 2, and at the transient time, an exhaust quantity of an exhaust gas is reduced and a revolving speed rises smoothly.</p> |
