Engine Control for Carbon Monoxide in Enclosed Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Engines operating in enclosed spaces pose safety concerns due to carbon monoxide emissions, particularly in vehicles with automatic start/stop capabilities, where operators may forget to shut down the engine, leading to potential accumulation of hazardous levels.
Innovation Solution
A carbon monoxide monitoring system that uses various sensors and location-determination methods to automatically shut down or prevent the starting of an engine, ensuring safety by reducing or eliminating emissions when the vehicle is in an enclosed space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic start/stop control is implemented to improve convenience, then ease of operation is improved, but safety deteriorates due to potential carbon monoxide accumulation when operator forgets to shut down engine
Solution Approach 1:
The system continuously monitors location data via GPS to detect when the vehicle is in an enclosed space, and automatically triggers engine shutdown or prevents automatic restart. This feedback loop eliminates the need for operator intervention while maintaining safety, resolving the contradiction between automated convenience and safety reliability.
2Productivity
If engine operates continuously to maintain readiness, then productivity is improved, but harmful factors worsen due to carbon monoxide emissions in enclosed spaces
Solution Approach 1:
The system dynamically adjusts engine operation status based on real-time location monitoring. When the vehicle is detected to be in an enclosed space, the engine is automatically shut down or prevented from automatic restart, reducing carbon monoxide emissions while maintaining operational readiness when appropriate.
3Reliability
If manual monitoring and shutdown procedures are required to ensure safety, then safety is improved, but device complexity increases due to additional monitoring systems and operator procedures
Solution Approach 1:
The system performs self-monitoring of location conditions and self-executes engine shutdown or prevention of automatic restart without requiring operator intervention. This automation maintains high safety levels while avoiding the complexity of manual monitoring procedures and operator training requirements.
Data Source
AI summary
An internal combustion engine is controlled in response to a location of the engine and an operational status of the engine to stop or reduce carbon monoxide emissions.
