Combustion Engine Additional Valve Unit for Fluid Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing internal combustion engine systems lack a versatile and efficient mechanism for managing multiple fluid systems, such as compressed air, exhaust, and fuel, which limits their operational flexibility and thermal management capabilities.
Innovation Solution
A device with an additional valve unit that can establish fluid connections between the combustion chamber and multiple fluid systems, including compressed air, exhaust, and fuel systems, allowing for multifunctional operation, dual-fuel capabilities, and improved thermal management by selectively switching between these systems using a control unit and idle travel device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional engine system with separate valves for each fluid system is used, then each fluid system can be managed independently, but the device complexity and number of components increase
Solution Approach 1:
The additional valve unit is designed to serve multiple functions by establishing fluid connections between the combustion chamber and different fluid systems (compressed air system, exhaust system, fuel supply system) through a single integrated component, replacing what would traditionally require separate valves and connection paths for each system
Solution Approach 2:
The patent combines multiple fluid connection paths and control functions into a single additional valve unit, merging the functionality of what would otherwise be separate valuation mechanisms for managing compressed air, exhaust, and fuel systems
2Adaptability or versatility
If an additional valve unit is added to manage multiple fluid systems, then operational flexibility and thermal management capabilities improve, but the device complexity increases
Solution Approach 1:
The additional valve unit provides universal access to multiple fluid systems (compressed air, exhaust, fuel) from the combustion chamber, enabling the engine to switch between different operational modes (compression, exhaust, fuel injection) through a single integrated component rather than requiring separate dedicated valves for each function
3Adaptability or versatility
If separate fluid systems are used for compressed air, exhaust, and fuel, then each system can be optimized independently, but the overall system complexity and space requirements increase
Solution Approach 1:
The patent merges multiple fluid connection paths into a single integrated valve unit structure, combining what would traditionally be separate physical systems for compressed air, exhaust, and fuel into one compact assembly that occupies less space while maintaining independent control capabilities for each fluid system

AI summary
The invention relates to a device (10) for an internal combustion engine for a motor vehicle, preferably a commercial vehicle, comprising several charge exchange valves (16) for supplying combustion air to a combustion chamber (14) of the internal combustion engine and for removing exhaust gas from the combustion chamber (14). The device (10) has a first fluid system and a second fluid system. The device (10) includes an additional valve unit (18) by means of which a fluid connection between the combustion chamber (14) and the first fluid system and a fluid connection between the combustion chamber (14) and the second fluid system can be established. The device (10) offers the advantage that the additional valve unit (18) is multifunctional.
