Claims

[Scope of Claim for Utility Model Registration] ■ A gas flow path GR that supplies a mixed gas of gas fuel and gas fuel from a mixer 4 is connected to the cylinder head 2, and a flow rate regulating valve is connected to the flow path GR. 3, and
For the mixer 4, an engine exhaust gas driven supercharger 5 is provided.
An air supply path r1 that supplies air from the air is connected to a gas fuel supply path r2, and the gas fuel supply path r2 is connected to the gas fuel supply path r2.
A flow path opening/closing valve 6 and a pressure regulating valve 7 are provided on the downstream side of the flow channel, and the operating diaphragm 16 of the pressure regulating valve 7 is connected to the spring 18.1 and the air supply channel r1. 2 pistons to the pressure increasing side by air,
In addition, the gas engine is provided to be operated to the pressure reducing side by the gas pressure after pressure adjustment, and a bypass flow path that communicates and connects a flow path portion on an upstream side and a flow path portion on a downstream side of the pressure regulating valve 7. r5 and its bypass flow path r
The two-stage operated bypass valve 2'0, which opens and closes the engine, is automatically opened and closed based on the information from the pressure detection device 1.22 so that it opens only under high engine load conditions. A gas engine is provided. (i) The bypass valve 20 is switched to an open state when the differential pressure between the gas pressure and the air pressure supplied to the mixer 4 becomes less than a set value, and to a closed state when the differential pressure becomes higher than the set value. A gas engine as set forth in claim 0 of the utility model registration claim provided in . (2) A utility model registration in which the bypass valve 20 is configured to be switched to an open state when the air pressure supplied to the mixer 4 exceeds a set value, and to a closed state when the air pressure becomes lower than the set value. A gas engine according to claim 0.
