Vehicle Fuel Type Detection via Engine Parameter Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to quickly and accurately detect when a vehicle's fuel tank has been filled with the wrong type of fuel, leading to potential engine malfunctions and increased repair costs, especially when the error is not detected during the vehicle's warranty period.
Innovation Solution
A vehicle system that includes a supervision computer which detects fuel type by analyzing engine operation after a predefined fuel consumption, storing data on suspected fuel type mismatches, and informing the driver or displaying messages if a malfunction is detected, allowing for post-repair diagnosis and troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no detection system is implemented, then the system remains simple, but fuel type errors go undetected causing engine damage
Solution Approach 1:
The supervision computer continuously monitors engine operation parameters (knocking, temperature, pressure) and compares them against expected values for correct fuel type. When deviations indicate wrong fuel detection, the system provides feedback to trigger alerts and store diagnostic data, enabling reliable detection without complex additional hardware
Solution Approach 2:
The engine's own operation characteristics serve as the detection mechanism. The supervision computer analyzes existing sensor data from the engine's normal operation (knocking sensors, temperature sensors, pressure sensors) to detect fuel type errors, eliminating the need for separate detection devices and allowing the system to self-diagnose fuel errors
2Loss of time
If detection is delayed until after-sales service, then no additional detection systems are needed, but engine damage increases and repair costs rise
Solution Approach 1:
The system performs preliminary detection of fuel type errors by continuously monitoring engine operation parameters during normal use. The supervision computer analyzes knocking patterns, temperature variations, and pressure fluctuations to identify wrong fuel before significant engine damage occurs, enabling early intervention and preventing catastrophic failures
Solution Approach 2:
The system rapidly analyzes engine parameters and quickly identifies fuel type errors through real-time monitoring of knocking and temperature data. By processing existing sensor information immediately and triggering alerts without delay, the system rushes through the detection process to minimize the time window for engine damage to occur
3Ease of repair
If warranty covers all repairs, then customer satisfaction increases, but manufacturer costs increase due to undetected fuel errors
Solution Approach 1:
The supervision computer acts as an intermediary that collects and analyzes engine operation data, storing diagnostic information about fuel type errors. This intermediary system provides objective evidence to distinguish between warranty-covered defects and customer-caused fuel errors, enabling accurate diagnosis and appropriate warranty application without manual investigation
Solution Approach 2:
The system replaces manual diagnostic procedures with automated electronic monitoring and analysis. The supervision computer electronically records and analyzes engine parameters, substituting mechanical inspection methods with digital data collection and analysis, thereby improving diagnostic accuracy and reducing the time and resources needed for post-repair diagnosis

AI summary
The invention relates to a vehicle (V) comprising: - a combustion engine (MT) supplied, by at least one injector (IN), with petrol as fuel originating from a tank (RC), in order to supply the torque to move it, and - a supervising computer (CS) controlling the supply and the operation of the combustion engine (MT), and, in the event of detecting a filling of the tank (RC) and then a restarting of the combustion engine (MT), detecting when the latter will have consumed a quantity of fuel equal to a predefined value, then, once this detection is performed, analysing the operation of the combustion engine (MT) over a chosen period, and, in the event of detecting a malfunction of the combustion engine (MT), triggering the storage of data representative of a suspected filling of the tank (RC) with a type of fuel different from petrol.
