GAS ENGINE CONTROL DEVICE

摘要

<P>PROBLEM TO BE SOLVED: To improve opening correction accuracy by calculating an opening correction value based on air-fuel ratio characteristics of each engine operation zone in the opening correction of a fuel gas supply quantity regulating valve. Ž<P>SOLUTION: A gas engine control device 1 is provided with an opening regulating means 200 regulating an opening GVM of a fuel gas supply quantity regulating valve 35 so at to converge actual combustion fluctuation PIV to a target combustion fluctuation value PIVm based on an engine load L, and an opening correcting means 300 forcibly increasing or decreasing the opening GVM of the fuel gas supply quantity regulating valve 35 at prescribed timing t_int and calculating an opening correction value GVM_rv based on a local maximum value and a local minimum value of the opening GVM during a convergence process to the target combustion fluctuation value PIVm. The gas engine control device is provided with a correction deployment means 400 defining a correction coefficient based on air-fuel ratio characteristics of each engine operation zone as a rated correction coefficient ε and deploying the multiplication of the rated correction coefficient ε to the opening correction value GVM to each engine operation zone.
