Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Factory turbocharged engines release manifold pressure at a predetermined level, undesirably dropping available power, necessitating a system to maintain higher turbo-boost for enhanced power output.
Innovation Solution
A turbo-boost controlled intake system with a control module that processes input signals from turbo inlet and manifold absolute pressure sensors to increase manifold pressure before release through the waste gate, using a wiring harness and signal adjuster for manual or automated power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the waste gate releases manifold pressure at the manufacturer-specified level, then the engine operates within factory parameters, but the available power level drops undesirably
Solution Approach 1:
The patent introduces a control module as an intermediary device between the waste gate and the manifold pressure system. This module intercepts and modifies the waste gate control signal to delay pressure release, thereby maintaining higher manifold pressure and boost levels without directly modifying the waste gate or other factory components.
Solution Approach 2:
The patent replaces the factory's mechanical/electrical waste gate control system with an electronic control module that uses sensor feedback and programmable logic to manage manifold pressure. This substitution enables precise control over pressure release timing, allowing the system to maintain optimal boost levels for enhanced power output.
2Stress or pressure
If the waste gate releases manifold pressure at manufacturer-specified levels, then the system operates as designed, but turbo-boost is lost prematurely
Solution Approach 1:
The control module performs preliminary action by pre-intercepting the waste gate control signal before the factory-specified pressure release point is reached. By modifying the signal in advance, the system delays pressure release and extends the duration of high manifold pressure, thereby maintaining turbo-boost longer and preventing premature power loss.
Solution Approach 2:
The patent implements a feedback control system that continuously monitors manifold pressure through a dedicated sensor and adjusts the waste gate control signal accordingly. This closed-loop feedback ensures that manifold pressure is maintained at optimal levels for the desired duration, extending turbo-boost persistence while preventing premature pressure release.
3Adaptability or versatility
If factory parameters are used for waste gate control, then installation is simple, but control over power output is limited
Solution Approach 1:
The control module is designed as a universal device that interfaces with standard factory components (waste gate, sensors, ECU) without requiring custom modifications. It performs multiple functions including signal interception, pressure monitoring, and adaptive control, thereby providing enhanced power output control while maintaining compatibility with various vehicle platforms and minimizing system complexity.
