To provide an auxiliary chamber gas supply device for a gas engine, the device that can inhibit variations of fuel gas supply amounts to an auxiliary chamber caused by the difference of electromagnetic valve individuals and improve stable combustion of the gas engine and performance of the engine.
In an auxiliary chamber gas supply device for a gas engine, an auxiliary chamber (4) is provided with auxiliary chamber gas supply paths (5, 14, 28, 29) that supply a fuel gas to the auxiliary chamber; the auxiliary chamber gas supply paths are connected with a fuel gas supply source (24) via an electromagnetic valve (23); the fuel gas amount corresponding to an opening time of an electromagnetic valve is supplied from the fuel gas supply source to the auxiliary chamber via the auxiliary chamber gas supply paths when the electromagnetic valve is left open; the opening time of the electromagnetic valve (23) is set so that a predetermined amount of fuel gas is supplied to the auxiliary chamber (4); and the auxiliary chamber gas supply paths (5, 14, 28, 29) are formed of a throttle part (30) which makes the opening time of the electromagnetic valve (23) prolong.
