<P>PROBLEM TO BE SOLVED: To secure an stable engine start even when a fuel gas having a large compositional variation is employed. <P>SOLUTION: A gas engine starting control method comprises a cell motor, a fuel gas supply device for supplying fuel gas into air for combustion, a rotation speed sensor for detecting engine rotation speed, and a control means for controlling a fuel gas supply amount by the fuel gas supply device. During an initial cranking period (T1) by the cell motor, the fuel gas supply amount by the fuel gas supply device is successively increased or decreased within a predetermined change range (W1). An initial explosion rotation speed value (Ns) when initial explosion occurs is detected by the rotation speed sensor to execute operation inputted in the control means. When an engine does not start during the initial cranking period (T1), cranking is re-executed by a fuel supply amount corresponding to the initial explosion rotation speed value (Ns), a fuel control valve opening (Qs1), for instance. <P>COPYRIGHT: (C)2012,JPO&INPIT |
