Solution Overview
Problem
Internal combustion engine systems in heavy-duty vehicles face operational issues due to liquid formation from condensation, which existing technologies have not adequately addressed, leading to potential damage and inefficiencies.
Innovation Solution
The implementation of an inlet system with at least two fluid sources and corresponding fluid guiding elements that create a pressure drop to drive fluid flow, reducing the risk of liquid formation and facilitating the distribution of condensation liquids for NOx suppression, utilizing a compressor with a rotor and air guide to guide air flow, and incorporating a conduit outlet arrangement to inject fluids towards the compressor's center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single fluid guiding element is used to guide condensate liquid, then the device complexity is low, but the reliability is insufficient due to inadequate fluid distribution and potential liquid formation problems
Solution Approach 1:
The fluid guiding element is divided into multiple segments (first fluid guiding element and second fluid guiding element), each with its own conduit (first conduit and second conduit) that independently guide fluid from different fluid sources. This segmentation allows for better fluid distribution and reduced liquid formation risks while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent introduces a pressure dimension by creating a pressure drop through the rotor that drives fluid flow through the second conduit. This pressure-driven flow mechanism adds a new dimension to fluid guidance, enabling the system to reliably transport fluid from multiple sources without requiring complex mechanical pumping mechanisms.
2Productivity
If fluid pressure at the second fluid source is low, then the device operation is simpler, but the fluid flow capability is insufficient to drive fluid to the air guide
Solution Approach 1:
The rotor acts as an intermediary that creates a pressure drop to mediate fluid flow from the second fluid source. By positioning the second conduit's downstream end so that the rotor-induced pressure drop drives fluid through it, the system enables flow from low-pressure sources without requiring additional pumping mechanisms, thus maintaining simplicity while improving fluid transport capability.
3Object-affected harmful factors
If condensation liquid accumulates in the system, then the device complexity remains low, but harmful factors increase due to operational problems and potential damage
Solution Approach 1:
The system converts the potentially harmful condensation liquid into a beneficial substance by guiding it through multiple fluid guiding elements to the air guide, where it suppresses NOx formation during engine operation. The restriction created by the rotor ensures proper fluid distribution, transforming what would be a harmful accumulation into a useful emission control mechanism without adding complex treatment systems.
