PURPOSE:To prevent occurrence of vapor-lock and to thereby improve the starting performance of an engine, by comparing the temperature of cooling water and the temperature of intake air with respective reference values at the time of starting the engine, and in case that the engine temperature is high, injecting fuel under high-temperature starting mode for a prescribed while. CONSTITUTION:In operation of an engine, the value Tw measured by a sensor 17 for detecting the temperature of cooling water is compared with a reference value Tw at a means for comparing the temperature of cooling water. In case of Tw<=TW, the output signal of said comparing means is applied to a means for instructing ordinary starting mode, wheareas in case of Tw>TW, the output signal is applied to a means for comparing the temperature of intake air. Further, in case of Tw>TW, the value Ta measured by a sensor 23 for detecting the temperature of intake air is compared with a reference value TA. In case of Ta<TA, the output signal of said comparing means is applied to the means for instructing ordinary starting mode, whereas in case of Ta>=TA, the output signal is applied to a means for instruction high-temperature starting mode. Through operation of said means for instructing high-temperature starting mode, a fuel injection valve 13 is controlled under the high temperature starting mode for a certain while determined by the output signal of an engine-speed sensor 9, and the starting mode is switched to the ordinary starting mode after the elapse of said certain while. |
