Inline Engine Signal Re-calibrator for Fuel Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
After-market solutions for recalibrating engine control units and air intake sensors lack a convenient and easily installable device that can modify sensor signals without replacing existing components, failing to address the need for adaptive fuel efficiency and combustion optimization.
Innovation Solution
An inline re-calibrator with a housing and electronic circuit that connects between the air intake sensor and engine control unit, modifying signal voltages or pulse-width modulation to recalibrate load tables based on pre-engineered rules and engine dynamometer calculations, allowing for efficient fuel use and combustion optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an inline re-calibrator is installed next to the mass air flow sensor, then ease of installation and identification is improved, but device complexity increases
Solution Approach 1:
The system is divided into separate functional components: the original mass air flow sensor remains in place, while a separate inline re-calibrator unit is installed adjacent to it. This segmentation allows the re-calibrator to be independently installed and removed without affecting the original sensor or ECU, thereby improving ease of installation while maintaining manageable device complexity through modular architecture.
2Use of energy by moving object
If signal modification is applied to recalibrate the ECU, then fuel efficiency is improved, but reliability of original system architecture is worsened
Solution Approach 1:
The inline re-calibrator serves as an intermediary device that sits between the mass air flow sensor and the ECU. It receives the original sensor signal, modifies it according to pre-programmed calibration algorithms, and delivers the recalibrated signal to the ECU. This intermediary approach enables fuel efficiency improvements through signal modification while preserving the reliability of the original sensor and ECU architecture, as neither original component is altered or replaced.
3Adaptability or versatility
If a separate re-calibration device is used, then adaptability to different engine types is improved, but device complexity increases
Solution Approach 1:
The inline re-calibrator incorporates dynamic adaptability through pre-programmed calibration algorithms that can be configured for different engine types, vehicle models, and performance requirements. The device can be programmatically adapted to various applications without requiring hardware modifications, allowing a single standardized device design to serve multiple engine configurations while maintaining low complexity through software-based flexibility rather than hardware variability.

AI summary
An apparatus for in-line re-calibration of engine load signal, the apparatus having a housing and a first connector disposed on the housing, adapted to plug into an electrical connection socket of an automotive air intake sensor. A second connector is disposed on the housing, adapted to mimic the electrical connection socket of the automotive air intake sensor. An electronic circuit is disposed in the housing, the electronic circuit adapted to re-calibrate signals from the automotive air intake sensor and deliver the re-calibrated signals the to the second connector. The housing is adapted to plug in-line directly into the electrical connection socket of the automotive air intake sensor, whereby the corresponding electrical wiring connector to an engine control unit plugs directly into the second connector of the housing, completing the inline connection.
