Remote Engine Diagnostic System for Non-Starting Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern engines are complex, requiring sophisticated diagnostic tools and procedures to diagnose issues like non-starting conditions, which can be time-consuming and impractical for remote locations due to the need for extensive equipment and multiple steps.
Innovation Solution
An engine diagnostic system with a control system, monitoring system, and communication system that allows for remote execution of diagnostic procedures while the engine is cranking, transmitting data to a remote location for analysis, thereby reducing the need for on-site diagnostic complexity and minimizing the number of replacement parts required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sophisticated diagnostic tools and multiple diagnostic steps are used to diagnose non-starting engine conditions, then diagnostic accuracy is improved, but diagnostic time and complexity increase significantly
Solution Approach 1:
The system performs preliminary diagnostic actions by automatically executing diagnostic procedures and collecting engine data before the technician arrives. The diagnostic system pre-analyzes engine parameters, sensor readings, and system states, preparing a preliminary diagnosis report that guides the technician's on-site actions, thereby reducing the actual diagnostic time at the remote location.
Solution Approach 2:
A communication system acts as an intermediary between the remote engine and the service center. This intermediary transmits engine data and diagnostic information remotely, enabling the service center to perform sophisticated analysis without requiring the technician to be physically present with complex diagnostic equipment, thus reducing diagnostic time while maintaining accuracy.
2Adaptability or versatility
If technicians carry large numbers of replacement parts to remote locations, then repair completeness is improved, but travel time and cost increase
Solution Approach 1:
The diagnostic system performs preliminary analysis of engine faults and identifies the specific replacement parts needed before the technician travels to the remote location. By pre-diagnosing the issue using transmitted engine data, the system enables the technician to carry only the necessary parts rather than a large inventory, reducing travel time and costs while ensuring repair completeness.
Solution Approach 2:
The system provides feedback to the technician about the specific diagnosis and required parts based on remote analysis of engine data. This feedback mechanism allows the technician to be precisely prepared with the correct parts for the identified issue, eliminating the need to carry excessive inventory while ensuring the ability to complete the repair.
3Ease of operation
If technicians travel to remote locations for engine diagnosis, then on-site diagnostic capability is improved, but service cost and time consumption increase
Solution Approach 1:
A communication system serves as an intermediary that enables remote diagnostic capabilities. The system transmits engine data to the service center and receives diagnostic instructions, allowing sophisticated analysis to be performed remotely without requiring the technician to travel with complex diagnostic equipment, thereby reducing service time and costs while maintaining on-site diagnostic capability.
Solution Approach 2:
The system replaces the need for physical presence of sophisticated diagnostic equipment and technicians at remote locations by substituting with automated diagnostic procedures and remote data transmission. The mechanical aspect of bringing heavy diagnostic tools to the site is replaced by electronic data communication, reducing both time and cost while preserving diagnostic capability.

AI summary
An engine diagnostic system includes an engine and a control system having a controller operatively connected to the engine. A monitoring system has a measurement device operatively connected to the engine. A diagnostic system is operatively connected to the engine. A communication system is configured to send and receive data from a remote location. The diagnostic system is configured to implement a non-starting engine diagnostic procedure, at least a portion of which is performed while the engine is cranking, and to transmit data generated during the engine diagnostic procedure to the remote location through the communication system.
