<p>PURPOSE:To switch the valve timing at earlier period when the variation rate is large, by varying the standard value of the parameter in the case when the valve timing is switched, according to the variation rate of the parameter. CONSTITUTION:The parameters such as the number of revolution are detected by an operation condition parameter detecting means C. In a memory means D, the operation condition of an engine, with each set values of the parameters such as load and number of revolution as boundary, is memorized. A timing controlling means E calculates the timing condition to be controlled on the basis of the detected signal, and in that case, a correcting means F corrects the standard value on which the timing is switched from a certain value to another value according to the number of revolution or the magnitude of the variation rate of other parameter. The signal for determining the timing to be set is transmitted to a control means B by a driving means G.</p> |
