ABSTRACT:
Herein disclosed is a fuel injection rate control system for starting a two-cycle engine having a fuel injection valve, which comprises: means for correcting the starting basic fuel injection rate, which is stored in advance in terms of an engine temperature, in accordance with the cranking engine speed at the enging starting time; and means for performing a correction in accordance with the cranking time period, wherein the improvement comprises, as the means for correcting the starting basic fuel injection rate in accordance with the cranking engine speed: first engine speed correction coefficient setting means for setting a first engine speed at a first start of the engine; means for deciding second later starts of the engine; and second engine speed correction coefficient setting means for setting an engine speed correction coefficient smaller than that of the first engine speed correction coefficient setting means when the second and later starts of the engine are decided by the decision means.
