PURPOSE:To perform the optimal control of an engine at its acceleration, by altering the compensated quantity of injected fuel depending on four levels of acceleration, in an automobile fuel injector employing a microcomputer. CONSTITUTION:The degree of opening of a throttle valve is sampled for every prescribed time to detect the acceleration of an engine from the sampled values. A compensated quantity of fuel is additionally injected depending on each of four levels of the acceleration. The difference DELTATH between the preceding and succeeding degrees of opening of the throttle valve is determined for classification to the four levels. For instance, the level ''1'' corresponds to the opening degree of 1-2.5, the level ''2'' the opening degree of 2.5-5, the level ''3'' the opening degree of 5-7, and the level ''4'' the opening degree of 7 or more. As a result, the engine is controlled in an optimal manner at its acceleration. |
