Zero-Governor Fitting Using Fuel Tank Support Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas engine generator units do not effectively utilize the lower half of the fuel tank, leading to inefficient arrangement of the zero-governor and fuel gas supply inlet-pipe, which results in transmission of engine vibrations and heat radiation to the zero-governor.
Innovation Solution
A zero-governor fitting structure is implemented using a fuel tank with two spaces of different depths, where the zero-governor is supported via a vibration insulation gasket on the shallower space and the gas supply inlet pipe and elbow joint are housed in the deeper space, allowing orthogonal gas flow direction and resilient support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the zero-governor is arranged in the upper half of the fuel tank, then the fuel tank can serve as a cover, but the lower half of the fuel tank is not utilized and additional components are needed
Solution Approach 1:
The fuel tank is divided into two functional spaces: the upper half serves as a cover housing for the zero-governor, while the lower half is utilized as a support box with a stay to hold the fuel gas supply inlet-pipe. This segmentation allows both halves of the fuel tank to be effectively utilized without increasing overall structural complexity
Solution Approach 2:
The fuel tank is designed to perform multiple functions: it serves as both a cover (upper half) and a support structure (lower half with stay) for the zero-governor and inlet-pipe arrangements, eliminating the need for separate dedicated support components
2Device complexity
If the zero-governor is exposed to engine vibrations and heat radiation, then the structure is simpler, but the zero-governor performance deteriorates
Solution Approach 1:
The zero-governor is extracted from the direct engine environment and placed in the upper half of the fuel tank, which serves as a protective cover. This spatial separation shields the zero-governor from engine vibrations and heat radiation, protecting its performance without requiring complex additional shielding structures
Solution Approach 2:
The fuel tank acts as an intermediary protective barrier between the engine (source of vibrations and heat) and the zero-governor (sensitive component). The fuel tank structure mediates the environmental exposure, providing thermal and vibrational isolation
3Device complexity
If the fuel tank lower half is not utilized, then the zero-governor arrangement is simpler, but the overall space utilization is inefficient
Solution Approach 1:
The fuel tank is segmented into two functional zones: the upper half for zero-governor housing and the lower half for inlet-pipe support via a stay. This segmentation enables efficient use of the entire fuel tank volume without complicating the zero-governor arrangement

Function Achieved in This Case
This configuration prevents the transmission of engine vibrations and heat radiation to the zero-governor, enables compact housing of the inlet pipe and elbow joint, and allows easy maintenance by allowing access through the fuel tank lid.

AI summary
A zero-governor fitting structure for a gas engine, configured in such a manner that the lower half of a fuel tank for a gasoline engine is utilized as a support box for supporting the zero-governor in which a gas supply inlet pipe and a zero governor can be reliably mounted with vibration and heating of the zero-governor avoided. A zero-governor mounting structure for a gas engine equipped with a zero-governor is provided with a support box fixed to the upper part of the gas engine. The support box is formed as a box having two depths. The zero-governor is supported, through a vibration insulation gasket, on the bottom plate of the shallower depth space of the support box. A gas supply inlet pipe and an elbow joint which is connected to the gas supply inlet pipe and can be bent the direction of the gas flow at a right angle toward the zero-governor are received in the deeper depth space, and the elbow joint is connected to the bottom inlet of the zero-governor.
