Abstract:
1. A zero-governor fitting structure for fitting the zero-governor to a gas engine, comprising at least one main chamber formed in a cylinder head so that air-fuel mixture of main fuel gas and air that are pre-mixed in an air-fuel mixer is burnt in the main chamber, and a zero-governor which establishes or regulates suitably a pressure of a fuel gas supplied to the air-fuel mixer, wherein a fuel tank which serves as a support box for supporting the zero-governor is provided to be fastened to an upper part of the gas engine, the support box being formed into a box body having two spaces of different depths, so that the zero-governor is fitted to a bottom plate of the shallower depth space of the support box via a vibration insulation gasket, and a gas supply inlet pipe and an elbow joint connected to the gas supply inlet pipe are housed in the deeper depth space of the support box, the direction of the gas flow from the gas supply inlet pipe is bent orthogonally toward the zero-governor at the elbow joint which is connected to a fuel gas inlet at the bottom of the zero-governor.
