Vehicle Engine Oil Pan Filter Mounting for Exhaust Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing engine designs for vehicles complicate the replacement of oil filters and oil coolers due to their placement under exhaust pipes, leading to increased manufacturing difficulties and longer, non-uniform exhaust pipe lengths.
Innovation Solution
The oil filter or oil cooler is attached to the oil pan, which is independently formed and lighter, allowing for simpler mounting and manufacturing, and positioned below the crankcase, enabling exhaust pipes to bypass them without bending, thus simplifying the exhaust pipe layout and facilitating easier replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the oil filter and oil cooler are attached to the front face of the crank case, then they are easily accessible for replacement, but the exhaust pipes must be routed in a complicated manner to bypass them, increasing device complexity and manufacturing difficulty
Solution Approach 1:
The oil filter and oil cooler are moved from the front face of the crank case to the lower surface of the crank case, changing the spatial dimension of their placement. This dimensional shift allows exhaust pipes to pass through the front side without complex routing, while the oil filter and cooler remain accessible from below for maintenance.
2Ease of operation
If the oil filter and oil cooler are attached to the front face of the crank case, then they are easily accessible, but mounting portions must be formed in the crank case itself, increasing manufacturing difficulty
Solution Approach 1:
The oil pan is separated from the crank case as an independent component. The oil filter and oil cooler are attached to the oil pan rather than the crank case, dividing the assembly into modular parts. This segmentation simplifies crank case manufacturing while maintaining accessibility for filter and cooler replacement.
3Ease of operation
If the exhaust pipes are routed to bypass the oil filter and oil cooler from the front side, then replacement is easier, but the exhaust path length increases and pipe shape becomes complicated
Solution Approach 1:
The oil filter and oil cooler are repositioned to the lower surface of the crank case, allowing exhaust pipes to maintain a straight forward path through the engine front. This spatial reconfiguration eliminates the need for lengthy bypass routes while preserving maintenance accessibility.

Function Achieved in This Case
This configuration allows for easier attachment and detachment of oil filters and oil coolers without complicating the exhaust pipe layout, reduces manufacturing complexity, and enables a larger bank angle for vehicles, while simplifying the oil supply path and eliminating the need for specialized fixing members.
Implementation Method 1
an oil pump drawing the oil from the oil pan and pressure feeding the oil to the lubricated positions via the oil supply path
Implementation Method 2
an oil cooler interposed in the middle of the oil supply path

AI summary
An engine for a vehicle for which the work of replacing an oil filter or an oil cooler is easily executed. The vehicle engine is provided with a crank case, a cylinder head having an exhaust passage outlet in a front face, an oil pan being independently formed from the crank case and attached to a lower surface of the crank case, an oil supply path communicating the oil pan with lubricated positions of the engine so as to circulate oil in the oil pan, an oil pump drawing the oil from the oil pan and pressure feeding the oil to the lubricated positions via the oil supply path, and an oil filter or an oil cooler interposed in the middle of the oil supply path and attached to a front face, a side face or a rear face of the oil pan.
