題がある。このため、圧縮空気始動式ガスエンジンでは
空気消費量が増加する。However, at the start of the start of the engine 6, since the supply pressure hardly increases, the loading pressure is low and the fuel gas passage of the regulator 3 is not sufficiently opened, so that the start is difficult. However, there are problems that the start-up time is long and the start-up fails frequently. For this reason, in the compressed air start type gas engine, the air consumption increases.

Is provided,
A means for supplying starting compressed air at the time of starting is provided in the loading pressure line of the regulator.

ける。FIG. 1 shows an embodiment of a compressed-air starting gas engine. A sub-compressed air supply line 12 is branched from a main compressed air supply line 11 for supplying the starting compressed air 10 to the engine 6.
Is connected to the loading pressure line 7. At the time of starting, the sub-compressed air supply line 12 is
Is provided with a starting electromagnetic valve 13 for supplying compressed air.
In addition, the starting electromagnetic valve 1 is connected to the sub-compressed air supply line 12.
From the third side, a primary pressure reducing valve 14, a secondary pressure reducing valve 15, and a check valve 16 for reducing the pressure of compressed air to an appropriate pressure are sequentially provided.

As a result, the fuel gas passage of the valve section 3a of the regulator 3 is temporarily opened widely. Therefore, a sufficient amount of fuel gas is supplied to the engine 6 for starting, so that starting is facilitated and starting time can be shortened. In addition, since the starting performance is improved, the consumption of the starting compressed air 10 is reduced, so that energy can be saved.
