<p><P>PROBLEM TO BE SOLVED: To provide a gas engine control device capable of controlling a combustion time of an air-fuel mixture in a specific time, regardless of a change with time. <P>SOLUTION: This gas engine control device includes an engine speed control part 111b for controlling the opening of a throttle valve 23 based on the deviation between an engine speed Ne and an engine speed command value NeO, an air-fuel mixture flow rate control part 111c for determining an air-fuel mixture flow rate command value QmixO from a load Ld and the engine speed command value NeO, calculating a viscosity corrected actual air-fuel mixture flow rate QmixR based on the air-fuel mixture temperature Tmix, air-fuel mixture pressure Pmix and the engine speed Ne and controlling the opening of a fuel gas control valve 42 based on the deviation between the air-fuel mixture flow rate command value QmixO and the viscosity corrected actual air-fuel mixture flow rate QmixR, and a discharge timing control part 111d for determining an exhaust temperature command value TgO from the air-fuel mixture flow rate command value QmixO and controlling timing when an ignition plug 16 discharges based on the deviation between an exhaust temperature command value TgO and the exhaust temperature Tg. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
