PURPOSE:To improve drivability by correcting the signal of a karman vortex type air flow sensor according to the number of engine revolution when the engine is in low-speed high-load operation state where Karman vortex is disturbed, thus improving the linkage between control zones. CONSTITUTION:In order to control fuel feed, the information supplied from an air flow sensor 1, engine revolution-number sensor 5, and a throttle opening sensor 4 for detecting the loaded state of the engine from the opening of a throttle valve 8 is read-in, and it is judged if the operation state of the engine E is within a prescribed karman vortex range or not. If the operation state is within the karman vortex rage, the correction coefficient in proportion to the erroneous operation of the air flow sensor 1 is multiplied with the fuel injection pulse time, and the second pulse control signal thus obtained is supplied into a fuel injection valve 2 from a computer 3, having preference to the first pulse control signal, and thus karman synchronous fuel injection is performed. |
