Work Vehicle Exhaust Gas Processing Device Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to maintain a compact vehicle body size in work vehicles equipped with multiple exhaust gas processing devices, as existing configurations often require significant space and lead to vehicle enlargement.
Innovation Solution
The solution involves strategically positioning and overlapping two exhaust gas processing devices, along with optimized piping and a coupling frame, to minimize space requirements and facilitate easy maintenance, while using a vibration absorber to stabilize the exhaust gas processing unit.

If multiple exhaust gas processing devices are accommodated in the inside of the work vehicle, then exhaust gas processing capability is improved, but vehicle body size increases
Solution Approach 1:
The patent positions the first exhaust gas processing device higher than the second exhaust gas processing device, utilizing vertical space rather than only horizontal arrangement. This three-dimensional configuration allows multiple devices to be accommodated within the same footprint area, improving exhaust gas processing capability without proportionally increasing vehicle body size.
Solution Approach 2:
The first exhaust gas processing device is partially overlapped with the second exhaust gas processing device in a top view, creating a nested or interlocking arrangement. This overlapping configuration maximizes space utilization by allowing devices to share vertical and horizontal space, reducing the overall footprint required for multiple exhaust gas processing devices.

AI summary
In a work vehicle, a second processing device, disposed over a hydraulic pump, is configured to process the hydraulic gas from an engine. A first processing device is disposed closer to the engine than the second processing device is. Further, the first processing device is positioned higher the second processing device. The first processing device is partially overlapped with the second processing device in a top plan view.
