Motorcycle Supercharger and Intercooler Layout for Intake Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In motorcycles, the combination of reduced engine displacement and supercharging to improve fuel economy and engine power poses challenges in efficiently cooling intake air and reducing turbo lag within the limited space, especially when using a supercharger and intercooler together.
Innovation Solution
The arrangement includes a supercharger positioned in front of the engine, an intercooler adjacent to the surge tank behind the cylinder head, and a configuration that shortens air paths and reduces the number of pipes, allowing for improved throttle response, weight reduction, and efficient cooling of intake air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the intercooler is added to cool the compressed air, then the intake efficiency is improved, but the device complexity and space requirement increase
Solution Approach 1:
The intercooler is integrated with the surge tank by positioning it adjacent to the surge tank behind the cylinder head. This merging of functions allows the intercooler to cool compressed air while the surge tank stores and regulates air flow, reducing overall system complexity and space requirement while maintaining effective cooling for improved intake efficiency
2Speed
If the air path is shortened to reduce turbo lag, then the throttle response is improved, but the arrangement complexity in limited space increases
Solution Approach 1:
The supercharger is positioned in front of the intercooler, and both are arranged behind the cylinder head in a compact configuration. This spatial arrangement in multiple dimensions shortens the air path from the supercharger through the intercooler to the surge tank and throttle bodies, improving throttle response while maintaining manageable arrangement complexity within the limited motorcycle engine space
3Temperature
If the supercharger and intercooler are positioned to optimize cooling, then the cooling efficiency is improved, but the weight and part count increase
Solution Approach 1:
The intercooler is positioned adjacent to the surge tank, merging their functional zones. This integration allows the system to achieve effective cooling of compressed air while reducing the total number of separate components and connections, thereby minimizing the weight increase associated with adding cooling capability to the supercharging system
