Engine Valve Actuated by Fastener for Fluid Spillage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing engine arrangements for turbocharger units in internal combustion engines face issues with fluid mixing and spillage during maintenance or replacement, as fluid ports are not effectively closed when the turbocharger unit is removed, leading to waste and potential contamination.
Innovation Solution
A valve system is integrated into the engine arrangement that automatically closes fluid ports unless the turbocharger unit is securely attached, ensuring fluid flow only when the units are properly connected, and automatically closing when the unit is removed to prevent spillage and mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the turbocharger unit is removed for maintenance or replacement, then the turbocharger unit can be accessed and removed, but fluid may spill out and mix if the fluid ports are not closed properly
Solution Approach 1:
The valve is designed to automatically close the fluid port before the turbocharger unit is completely removed, preventing fluid spillage in advance. The fastening member's movement during the removal process triggers the valve closure as a preliminary action, ensuring fluid containment before the unit is fully disengaged.
Solution Approach 2:
The system uses the positional feedback of the fastening member during mounting and removal to automatically control the valve state. When the fastening member is in the mounted position, the valve opens to allow fluid flow; when moved to the removed position, the valve closes to prevent spillage, creating an automatic feedback-controlled system.
2Reliability
If fluid ports are kept open for fluid flow between engine units, then lubrication and cooling are provided, but fluid mixing and waste occur when units are disconnected
Solution Approach 1:
The valve transitions from a static open/closed state to a dynamic state that automatically adjusts based on the connection status. The valve moves between open and closed positions in response to the fastening member's position, enabling the system to adapt fluid flow conditions to the operational state, ensuring reliability when connected and preventing loss when disconnected.
Solution Approach 2:
The system uses the mechanical movement of the fastening member itself to operate the valve, eliminating the need for separate control mechanisms. The fastening member's own motion during mounting and removal directly actuates the valve, allowing the system to self-regulate fluid flow based on its operational state.
3Object-affected harmful factors
If a valve system is added to control fluid ports automatically, then fluid spillage is prevented, but device complexity increases
Solution Approach 1:
The valve control function is merged with the existing fastening mechanism. The same fastening member that secures the turbocharger unit also serves to actuate the valve through its movement. This integration combines two functions (mechanical fastening and fluid control) into a single mechanism, reducing overall system complexity while maintaining spillage prevention.
Solution Approach 2:
The fastening member is given multiple functions: it mechanically secures the turbocharger unit to the engine block and simultaneously controls the valve to regulate fluid flow. This multi-functionality eliminates the need for separate control components, reducing device complexity while achieving automatic fluid port management.

AI summary
An engine arrangement includes a first engine unit, a second engine unit and at least one member for fastening the second engine unit to the first engine unit. The first unit and the second unit include fluid ports for achieving a fluid flow between the first and second unit. The engine arrangement further includes a valve for opening and closing at least one of the fluid ports and the fastening member is moveably arranged relative to the first unit and second unit and is arranged to act on the valve.
