Compact Engine Layout via Opposite-Side Turbocharger Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional engines with two-stage turbochargers lack a compact configuration due to the close placement of high-pressure and low-pressure turbochargers, which results in underutilized space and a complex engine layout.
Innovation Solution
The high-pressure and low-pressure turbochargers are separately disposed on opposite sides of the engine body, with intake and exhaust pipes positioned transversely, allowing for a more compact arrangement and improved maintenance access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the high-pressure turbocharger and the low-pressure turbocharger are disposed close to each other and connected by intake pipe and exhaust pipe, then the engine can achieve two-stage turbocharging function, but the space utilization is poor and the engine configuration cannot be made compact
Solution Approach 1:
The patent applies dimensional arrangement by disposing the high-pressure turbocharger and low-pressure turbocharger on opposite sides of the engine main body in the longitudinal direction, with intake and exhaust pipes arranged in the transverse direction. This spatial distribution across different dimensions achieves compact engine configuration while maintaining two-stage turbocharging functionality.
2Device complexity
If the high-pressure turbocharger and the low-pressure turbocharger are disposed close to each other, then the connection between turbochargers is simplified, but the space where turbochargers are disposed is not utilized effectively
Solution Approach 1:
The patent segments the turbocharger system by separating the high-pressure turbocharger and low-pressure turbocharger into different locations on opposite sides of the engine main body. This segmentation allows each turbocharger to be positioned independently to optimize space utilization while maintaining functional connectivity through transverse intake and exhaust pipes.
3Volume of moving object
If the intake pipe and exhaust pipe are disposed separately on one side and the other side in transverse direction, then the engine configuration becomes compact, but the pipe layout complexity increases
Solution Approach 1:
The patent employs asymmetric arrangement by positioning the intake pipe and exhaust pipe on opposite sides of the engine main body in the transverse direction. This asymmetric layout achieves compact engine configuration while the pipes connect the high-pressure and low-pressure turbochargers located on opposite sides, balancing the overall structure.
