Swiveling Work Machine Fuel Cylinder Layout and Nested Mufflers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swiveling work machines face challenges in using alternative fuels, managing space for tools and maintenance parts, and reducing exhaust temperature and noise while maintaining a compact installation space.
Innovation Solution
The swiveling work machine is designed with a swivel base, a prime mover that can be driven by fuel from a fuel cylinder, and an exhaust structure that includes multiple mufflers to reduce exhaust temperature and noise. The fuel cylinder is supported by a mechanism that allows it to be shifted between an installation position and a retracting position, and it is equipped with a reserve cylinder to ensure continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a large muffler or multiple mufflers are installed to reduce exhaust temperature and noise, then the exhaust reduction effect is improved, but the installation space requirement increases
Solution Approach 1:
The exhaust structure employs nested mufflers where a first muffler is placed inside a second muffler, and a third muffler is placed inside the second muffler. This nested arrangement allows multiple mufflers to occupy a compact radial space while maintaining the cumulative noise and heat reduction benefits of multiple stages, effectively resolving the contradiction between exhaust reduction performance and installation space requirements.
2Productivity
If multiple types of fuel are used alternatively, then the fuel efficiency and environmental performance are improved, but the fuel management system complexity increases
Solution Approach 1:
The prime mover is designed with multi-functionality to operate on multiple fuel types (diesel and alternative fuels such as natural gas or LPG). The fuel management system incorporates universal components including a fuel selection valve that can route different fuel sources, and a control system that automatically adjusts injection parameters based on the selected fuel type. This universal design enables the machine to achieve improved fuel efficiency and environmental performance while keeping the added system complexity manageable through integrated control.
