V-Type Engine Charge Air Layout for Standardized Duct Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Turbo-charged internal combustion engines require different designs of charge air pipes and components due to non-standardized turbocharger positions, leading to increased material costs and part diversity.
Innovation Solution
A V-type internal combustion engine design with charge air coolers positioned on opposite axial sides, implementing a diagonal concept that allows for the use of identical components across cylinder banks, including charge air pipes, manifolds, and blow-by systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If charge air coolers are arranged on the same axial side of the engine, then the engine layout is conventional and compact, but different parts are required for charge air ducts between different cylinder banks
Solution Approach 1:
The patent applies asymmetry by positioning charge air coolers on opposite axial sides of the V-type engine (diagonal arrangement). Specifically, the first charge air cooler is positioned on a first side of the first cylinder bank, while the second charge air cooler is positioned on an opposing second side of the second cylinder bank. This asymmetric diagonal configuration enables symmetric routing of charge air ducts from both turbocharger arrangements to their respective coolers, allowing identical duct designs to be used for both cylinder banks, thereby reducing part diversity and manufacturing costs
2Adaptability or versatility
If turbocharger positions are non-standardized, then different engine configurations can be adapted, but the number of different charge air pipe designs increases
Solution Approach 1:
The patent implements universality through a standardized diagonal charge air architecture that can serve multiple engine configurations (V12, V16, V20, etc.). The diagonal arrangement of charge air coolers on opposite axial sides creates a universal template where identical charge air ducts, manifolds, and piping components can be used across different cylinder bank configurations, reducing the need for configuration-specific custom parts while maintaining adaptability
3Adaptability or versatility
If multiple different charge air pipe designs are used, then different turbocharger configurations can be supported, but material costs increase
Solution Approach 1:
The asymmetric diagonal positioning of charge air coolers on opposite axial sides of the engine enables symmetric routing paths for charge air ducts. This configuration allows the same duct designs and material specifications to be used for both cylinder banks regardless of turbocharger arrangement variations, significantly reducing material costs by eliminating the need for multiple different pipe designs
