Saddle-Ridden Vehicle Cooling Piping Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saddle-ridden type vehicles with supercharged engines face challenges in adequately cooling the oil cooler and supercharger, leading to unstable cooling water temperatures, which can impact engine performance.
Innovation Solution
A cooling piping system with separate inlet and outlet pipes for the oil cooler and supercharger, converging above them, ensures efficient cooling and temperature stabilization by using fresh cooling water from a water pump, and includes a radiator for temperature regulation and vapor management to maintain cooling even after engine shutdown.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cooling water having cooled the engine is used to cool the oil cooler and supercharger, then the cooling system can utilize existing cooling water, but the oil cooler and supercharger cannot be sufficiently cooled and the cooling water temperature becomes unstable
Solution Approach 1:
The cooling water circulation system is segmented into multiple independent circulation paths: a first circulation path for the engine, a second circulation path for the oil cooler, and a third circulation path for the supercharger. This segmentation allows each component to receive cooling water at appropriate temperatures independently, preventing temperature instability while maintaining system complexity at an acceptable level.
2Loss of energy
If high-temperature cooling water from the supercharger is mixed with low-temperature cooling water from the radiator, then the cooling water can be reused, but the temperature of cooling water supplied to the engine becomes unstable
Solution Approach 1:
The cooling water circulation system is divided into separate circulation paths that prevent mixing of cooling water at different temperatures. The engine cooling path, oil cooler path, and supercharger path are independently configured, ensuring that temperature-stable cooling water is always supplied to the engine while allowing other components to use cooling water at various temperatures without affecting engine cooling stability.
3Device complexity
If the cooling water passage for supply is used for both engine cooling and supercharger cooling, then the system structure is simplified, but the cooling performance of both components deteriorates
Solution Approach 1:
The cooling system is segmented into distinct circulation paths with dedicated inlet and outlet passages for each component (engine, oil cooler, supercharger). This segmentation ensures adequate cooling performance for each component by providing sufficient cooling water flow independently, while the overall system structure remains organized and manageable through clear separation of functions.

AI summary
There is provided a saddle-ridden type vehicle. An oil cooler cools engine oil to be supplied to an engine. A supercharger compresses combustion air to be supplied to the engine. A water pump pumps cooling water to the engine and the supercharger. A cooling piping flows the cooling water delivered from the water pump. A first inlet piping supplies the cooling water to the oil cooler. A second inlet piping is disposed in parallel with the first inlet piping and supplies the cooling water to the supercharger. A first outlet piping extends upward from the oil cooler and returns the cooling water to the water pump. A second outlet piping extends upward from the supercharger and returns the cooling water to the water pump. The first outlet piping and the second outlet piping converge above the oil cooler and the supercharger.
