DEVICE AND METHOD OF CONTROLLING GAS ENGINE

摘要

A control system (30) for controlling a power output of a gas engine (1) of the present invention comprises a target value setting section (43) for setting as a target value (KW T ) a restricted power output which is less than a predetermined power output when a source gas pressure (P0) of a gas fuel is less than a predetermined value (P0 m_100 ) required to inject the gas fuel against an intake-air pressure (PB 100 ) according to the predetermined power output, a power output setting section (44) for setting a set value (KW SET ) of a power output (KW) based on the target value (KW T ) set by the target value setting section (43), and a power output control section (45) for controlling the power output (KW) so that the power output (KW) reaches the set value (KW SET ) set by the power output setting section (44).
