| description | PURPOSE: A method for compensating accelerating and decelerating air fuel ratios in a turbocharger engine vehicle is provided to reduce exhaust gas while improving accelerating performance through compensating air fuel ratio. CONSTITUTION: A table data map is set by recognizing intake characteristic of a turbocharger engine. Then, the value of an intake manifold absolute pressure sensor is inputted in traveling(20). An accelerating state and a decelerating state are decided by using the difference between the input value and a prior value(21). In case of accelerating or decelerating state, a turbocharger value at change in speed and a turbocharger value at an injection calculation point are read to calculate a turbocharger compensating value(22). Then, a compensating amount is calculated by using a turbocharger compensating value(23). Moreover, a fuel amount is calculated by using the compensating value(24). |
