Problems solved by technology
[0002] The gas injection valves of gas engines in the prior art are mostly installed on the air intake pipeline outside the cylinder head of the engine. This installation method requires a special mounting seat or pipe joint on the air intake pipeline to connect the structural load. It is not easy to assemble, the structural stability of the gas injection valve cannot be guaranteed, and the installation cost is high

The invention belongs to the technical field of marine engine manufacturing and assembly, and in particular, relates to a gas injection valve mounting structure of an engine. A gas injection valve ismounted on an engine cylinder head; the engine cylinder head is provided with a through hole; the through hole penetrates into an air intake pipeline in the cylinder head; and an injection pipe of thegas injection valve penetrates through the through hole, and convexly extends into the air intake pipeline in the cylinder head. The gas injection valve is directly mounted on the cylinder head of the engine, so that the mounting structure of the gas injection valve is simplified, and the structural stability of the gas injection valve is guaranteed; and an outlet of the injection pipe of the gasinjection valve is an inclined port towards the inner end of the air intake pipeline for preventing gas from flowing back in the air intake pipeline.
Description
technical field [0001] The invention belongs to the technical field of manufacturing and assembling of marine engines, and in particular relates to a gas injection valve installation structure of the engine. Background technique [0002] The gas injection valves of gas engines in the prior art are mostly installed on the air intake pipeline outside the cylinder head of the engine. This installation method requires a special mounting seat or pipe joint on the air intake pipeline to connect the structural load. It is inconvenient to assemble, the structural stability of the gas injection valve cannot be guaranteed, and the installation cost is relatively high. Contents of the invention [0003] The object of the present invention is to provide a gas injection valve installation structure of an engine which facilitates the assembly of the gas injection valve. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a ga...
