Integrated Fresh Gas Housing for Turbocharged Engines
Solution Overview
Problem
Existing fresh gas supply devices for internal combustion engines with exhaust gas turbochargers have a high number of components and lengthy assembly times, complicating production and installation.
Innovation Solution
A housing design for the fresh gas supply device consisting of a main part and a removable cover, with integrated components such as a charge air inlet, flap element, quantity regulating device, and non-return valve, allowing for simplified assembly and reduced component count by combining functions within a split housing structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fresh gas supply device is equipped with multiple functional components (flap element, quantity regulating device, non-return valve, etc.), then the device can perform complete fresh gas supply functions, but the number of parts increases and assembly time becomes lengthy
Solution Approach 1:
The patent combines multiple functional components (flap element, quantity regulating device, non-return valve) into a single integrated housing structure. The housing serves as both the structural container and the mounting framework for all control components, eliminating the need for separate housings or mounting structures for each component. This merging approach maintains full functional capability while significantly reducing the total number of discrete parts and simplifying assembly procedures.
Solution Approach 2:
The housing is designed as a multi-functional element that simultaneously serves as: (1) the structural container for the fresh gas supply device, (2) the mounting structure for the flap element, (3) the framework for the quantity regulating device, and (4) the support for the non-return valve. This universal design allows a single component to fulfill multiple roles, reducing overall device complexity while maintaining adaptability and functional completeness.
2Manufacturing precision
If multiple separate components are used in the fresh gas supply device, then each component can be optimized independently, but the assembly and installation time increases
Solution Approach 1:
The housing is designed with a segmented structure featuring a removable cover that can be separated from the main housing body. This segmentation allows for independent optimization of different functional zones while enabling modular assembly and disassembly. The removable cover design facilitates easy access to internal components for maintenance and assembly, reducing installation time without compromising the ability to optimize each functional component independently.
3Device complexity
If a complex housing structure is used to accommodate all functional components, then all components can be integrated, but production and machining complexity increases
Solution Approach 1:
The housing is divided into a main housing body and a removable cover, creating two simpler manufacturing zones. This segmentation allows each part to be produced with simpler tooling and processes, then assembled together. The removable cover design maintains integration of all functional components while avoiding the need for a single complex monolithic housing structure that would be difficult and expensive to manufacture.
