V-Type Engine Diagonal Charge Air Layout for Parts Standardization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Turbocharged 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 of the cylinder banks, implementing a diagonal concept that allows for the use of identical parts for charge air ducts, manifolds, and other components across both banks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If charge air coolers are arranged on the same axial side of the engine, then the engine can operate with conventional turbocharger configurations, but the design diversity of charge air pipes and components increases, leading to higher material costs
Solution Approach 1:
The patent applies asymmetry by positioning charge air coolers on opposite axial sides of the engine (diagonal arrangement). This asymmetric configuration enables the use of identical, standardized charge air pipes and components for both cylinder banks, thereby reducing part diversity and material costs while simplifying the overall charge air architecture
Solution Approach 2:
The diagonal arrangement of charge air coolers allows the same charge air pipe design to serve both cylinder banks universally. This multi-functional approach eliminates the need for separate, bank-specific piping designs, reducing the number of different parts required and lowering manufacturing complexity
2Adaptability or versatility
If different turbocharger configurations are used for different cylinder numbers, then the engine can be adapted to various applications, but the number of different parts required increases
Solution Approach 1:
The standardized diagonal charge air architecture with identical components for both cylinder banks creates a universal system that can be adapted to different engine configurations (V12, V16, V20, etc.) without requiring different parts. This multi-functional design maintains engine versatility while significantly reducing part diversity
Solution Approach 2:
The engine is segmented into two independent but symmetrical cylinder banks, each with its own turbocharger arrangement and charge air cooler positioned on opposite axial sides. This segmentation allows each bank to be configured independently while using identical standardized components, enabling adaptability across different cylinder numbers without increasing part diversity
